Introduction
1.1 Importance of Construction Fire Safety
Buildings face the greatest risk from fires during the construction phase. In recent
years, there have been several examples across Canada of major construction site
fires, including those in Calgary, Alberta in March 2015, Kingston, Ontario in
December 2013 and Richmond, British Columbia in 2011.
Myriad risks exist at construction sites, including:
• Proximity of combustible materials to ignition sources (e.g. electrical
equipment and hot work such as welding);
• Lack of completion of any built-in fire -safety systems such as sprinklers;
• Absence of doors, finished walls and other separations that may slow fire
spread; and
• Potential site security issues.
It is estimated that more than 100,000 building projects in Canada each year
involve wood -based construction (e.g. wood -frame, post -and -beam, mill or cross -
laminated timber).
With this widespread and growing use of wood — due in part to building code
changes permitting taller wood buildings — comes the need for a greater focus on
construction fire safety. Although research' shows that wood buildings are as safe
as those built with steel and concrete when effective fire -safety systems are in
place, like all buildings, they are more vulnerable to fires when they lack those
systems — as is the case during construction.
5
Financial Losses
A focus on construction fire safety also makes good business sense. Financial losses
can be significant, as fire departments in general take a defensive approach to
construction site fires.' Because there is typically little to no need for occupant
rescue in a building under construction, protecting firefighter safety and preventing
fire spread usually are the main focuses.
1.2 Scope
The intent of this manual is to reduce the risk of and losses from construction site
fires. The manual provides Canadian builders with practical tools and information
based on best practice, legislation, regulation and standards from Canada, the
United States and Europe. (For more analysis of this topic, please see the research
paper Construction Fire Response: Preventing and Suppressing Fires during
Construction of Large Buildings at www.cwc.ca.)
Regulation related to buildings under construction varies across the country, and
the information in this guide may not reflect the local, provincial and national
regulation in all areas. It is important to research, understand and comply with all
area -specific fire safety regulations before construction and throughout the project.
(See the Legislation, Regulation and Other Guidelines section for more
information.)
While the focus of this manual is on the design, planning and construction phases
for new buildings, the information may also be relevant to projects involving
demolition, alteration, renovation, repair and maintenance of existing buildings.
1.3 Responsibility for Fire Safety
Fire safety is the responsibility of everyone involved in construction projects,
including the construction industry, employers, workers, site visitors, and provincial
and local authorities. Each participant has a specific role that, when combined with
the efforts of others, can help to reduce the risk of construction site fires.
Construction Industry
The construction industry has made significant improvements in its efforts to
support on-site safety over the years. With the increased focus on construction fire
safety, industry associations such as the Canadian Wood Council are stepping
forward to provide resources and information to members, designers, builders and
regulators.
Employers
Provincial Occupational Health and Safety regulations require the provision of a
safe work environment. To properly implement and evaluate safety at their sites,
employers should have a comprehensive policy that covers all levels of the
company, from management to labour. Construction companies should emphasize
the need for fire safety and create a mindset amongst all employees that fire safety
is a top priority.
Workers
It is critical that workers follow prescribed safety methods of work and
demonstrate concern for the health and safety of themselves, fellow employees
and others who may be affected by their actions. Workers should:
• Report all potential fire hazards;
• Observe all fire safety rules, procedures and codes of safe practices; and,
• Use, with all reasonable care, the tools, safety equipment and personal
protective equipment (PPE) appropriate to the worksite.
Site Visitors
Individuals visiting jobsites should be required to check in with the site supervisor,
who should ensure visitors are made aware of the site safety procedures.
They should also be required to wear appropriate PPE, including, at minimum:
• Hard hat and safety vest;
• Goggles; and
• Appropriate safety shoes or other footwear.
While on the jobsite, visitors should:
• Stay visible;
• Remain alert and aware of their surroundings;
• Never approach equipment unless the operator has acknowledged their
presence; and
• Never park vehicles in a way that blocks fire department access.
Authority Having Jurisdiction
Fire Protection and Construction
Fire and building regulations are typically enforced at the local government level:
• Building Department: Enforces and oversees building construction in
accordance with local bylaws, and provincial legislation and codes.
• Fire Department:
o Fire Prevention Division: Enforces local fire bylaws and provincial
fire codes.
o Fire Suppression Division: Works with project representatives to
develop pre -fire plans and assess water supply, access and
exposure protection.
Health and Safety
Occupational Health and Safety regulations are enforced by provincial workplace
health and safety agencies.

This document was created as a response to try to avert future catastrophic events
(e.g. a fire or building collapse), such as those faced by the construction industry
over the last decade. As illustrated in the diagram, catastrophic events usually have
a low probability of occurring, but high consequences when they do occur. Despite
the potential severe consequences, however, human nature is such that routine
events are easily accepted but catastrophic events are seldom contemplated and
are difficult to accept.
It is important that senior company managers demonstrate leadership in managing
the risks associated with catastrophic events. As noted American businessman and
humourist Arnold Glasow said, "One of the true tests of leadership is the ability to
recognize a problem before it becomes an emergency."

Legislation, Regulation and Other
Guidelines
Construction fire safety in Canada is addressed through a variety of legislation,
regulation, standards and guidelines.
2.1 Federal
National Model Construction Codes are developed and maintained by the Canadian
Commission on Building and Fire Codes (CCBFC), an independent committee
established by the National Research Council.
The model codes include the National Building Code, the National Fire Code, the
National Plumbing Code and the National Energy Code. Provinces and territories
may adopt the codes as their own, either as -is or with amendments.
National Building Code of Canada (NBCC)
Part 8 of the NBCC 2010 includes construction site regulations! Provinces and
territories that have adopted Part 8 with little or no modification are:
British Columbia
Northwest Territories
Saskatchewan
Nova Scotia
Manitoba
Nunavut
Quebec
Yukon
New Brunswick
Prince Edward Island
Newfoundland and Labrador
The 2012 Ontario Building Code does not include requirements for fire and life
safety at construction sites.
* The NBCC was under review at the time of publication of this guide; the 2015 version is
expected to permit the construction of wood buildings of up to six storeys, from the current
four storeys. No changes are proposed for Part 8 of the NBCC 2015.
A
National Fire Code of Canada (NFCQ
Section 5.6 of the NFCC covers construction site fire and life safety! Provinces and
territories that have adopted the NFCC with little or no modification are:
Saskatchewan Newfoundland and Labrador
Manitoba Northwest Territories
Quebec Nova Scotia
New Brunswick Yukon
British Columbia and Alberta have province -specific construction and demolition
safety sections in their provincial fire codes.
The 2012 Ontario Fire Code does not include requirements for fire and life safety at
construction sites. However, the 2014 Ontario Fire Code does cover fire and life
safety for demolition (Part 8) and during repairs or renovations (Article 2.6.1.10).
Nunavut and Prince Edward Island have not adopted fire regulations that address
fire and life safety at construction sites.
2.2 Provincial
Provincial Occupational Health and Safety (OHS) regulations primarily focus on the
protection of workers and others present at workplaces. Worker safety at
construction sites is commonly addressed through general OHS provisions,
although some regulations have additional specific provisions for construction sites,
such as in Ontario.
Construction site OHS in Canada is addressed through the following regulations:
• British Columbia Occupational Health and Safety Regulation
• Alberta Occupational Health and Safety Code
• Saskatchewan Occupational Health and Safety Regulations
• Manitoba Workplace Safety and Health Regulation
• Ontario Occupational Health and Safety Regulation, Construction Projects
• Quebec Act Respecting Occupational Health and Safety
• Newfoundland and Labrador Occupational Health and Safety Regulations
• Nova Scotia Occupational Safety General Regulations
• New Brunswick Workers' Compensation Regulation
• Prince Edward Island Occupational Health and Safety Act, General
Regulations
• Yukon Occupational Health Regulations
• Northwest Territories Occupational Health & Safety Regulations
* The NFCC was under review at the time of publication of this guide; the 2015 version is
expected to include additional provisions in Section 5.6 for construction of wood buildings
of up to six storeys.
Its]
Hot Work Permits
Hot work requirements vary across Canada. While all jurisdictions require
employers to have appropriate safety measures and safe work procedures for hot
work, Alberta is the only province where the provincial OHS regulations require hot
work permits.
Other jurisdictions have adopted the Canadian Standards Association's W117.2
standard Safety in Welding, Cutting and Allied Processes to address hot work safety.
(See Other Standards and Codes below for more information.)
Even where hot work permit systems aren't required, they can provide a useful
checklist of activities that help ensure the safety of employees and the worksite, as
well as compliance with the safe work procedures in your area.
See the Hot Work subsection in the Fire Prevention and Protection Best Practices
section of this guide for a hot work permit checklist.
2.3 Local Government
Several cities in Canada have published guidance related to construction site fire
and life safety, or interpretations of provincial regulations. These documents are
primarily intended to supplement, interpret and facilitate compliance with
mandatory construction and fire regulations. Topics covered include construction
site fire safety plans, protection of adjacent buildings, general construction and
demolition site safety, and construction site fencing and barricading.
Prior to starting a construction project, it is advised to check with the local fire
department for any area -specific bulletins or guidance.
2.4 Company Policy
No employee can be required to work at a jobsite they believe is not safe. All
construction companies should have a policy that makes the health and safety of
employees the highest priority. Eliminating unsafe working conditions and work
practices begins with a company policy that establishes safety rules, policies and
procedures that may be grounds for dismissal if not followed.
2.5 Other Standards and Codes
National Fire Protection Association (NFPA)
The NFPA produces standards that serve as the basis for many fire codes and fire
prevention practices adopted by the construction industry. Relevant NFPA
standards include:
• NFPA 241 Standard for Safeguarding Construction, Alteration, and
Demolition Operations;
• NFPA 1620 Standard for Pre -Incident Planning; and
• NFPA 51B Fire Prevention in the Use of Cutting and Welding Processes.
11
Canadian Standards Association (CSA)
The CSA Group is accredited in the U.S. and Canada to develop standards in a wide
range of subjects related to product safety and performance, process improvement,
best practices and safer work environments.
A number of jurisdictions, including BC, Manitoba, New Brunswick, Newfoundland
and Nova Scotia, look to the CSA W117.2 standard, entitled Safety in Welding,
Cutting and Allied Processes, for guidance in hot work safety. The standard can be
viewed for free at ohsviewaccess.csa.ca.
International Code Council (ICC)
The ICC develops model codes and standards used in design, building and
compliance processes to construct safe, sustainable, affordable and resilient
structures. The ICC produces two documents that are relevant to construction fire
safety: the International Building Code and the International Fire Code. Although
the codes focus on the United States, both documents provide good practices that
are relevant to the construction industry in Canada.
2.6 Insurance Industry Perspective
The private property and casualty insurance industry in Canada writes more than
$45 billion in premiums and pays out about approximately 60% in claims annually.
The industry has had a longstanding concern about large and devastating
condominium and apartment fires, and is cautious when dealing with this line of
business, particularly for projects under construction.
A focus group of insurance industry representatives was conducted in May 2014 for
the development of the Report on Course of Construction (Fire) Best Practices
Guide for the Canadian Wood Council. Participants had both strong underwriting
and loss prevention backgrounds, and included the two largest private property
and casualty insurers in Canada. All participants provided Course of Construction
(Builder's Risk) insurance coverage.
Construction companies might wish to consider the key concerns of this group,
summarized below:
❑ The site water supply should be assessed in the planning stages to ensure
there is sufficient water to supply the sprinkler system, standpipes and
hose, and fire department requirements, both during and after
construction.
❑ A fire plan for the construction phase should be in place before
construction commences and reviewed before construction advances
above ground level.
❑ The site should be supervised 24/7, with regular tours of the entire jobsite.
❑ No smoking should be permitted inside the fenced jobsite perimeter.
❑ The standpipes and hose should be installed and activated as the structure
is being built (one floor below the floor under construction).
❑ Sprinkler systems should be installed and activated floor -by -floor as the
structure is being erected (two floors below the floor under construction.)
12
❑ Sprinkler systems should be installed as designed (wet or dry), but
temporarily used as dry -pipe systems and only converted to wet systems
when the risk of freezing is no longer present.
❑ When hot work is being performed in non-sprinklered areas, staffed and
charged fire hoses should be in place. If possible, employ off-duty
firefighters to staff the hoses.
❑ No open -flame heating should be used.
❑ The erection of fire barriers/separation walls should be prioritized on each
floor, and fire doors should be installed as soon as the door's framing is in
place. Protocols should ensure the fire doors are then kept closed after
normal working hours.
❑ Firewalls with parapets (or equivalent) that are integral to the approved
project design should be installed using a two-storey lag.
❑ To help reduce the amount of project values susceptible to any fire loss,
construction of multiple buildings at the same site should be staged to
create a 30 -metre firebreak until active fire protection and the
noncombustible exterior are installed, before filling in the remaining
buildings.
❑ The insurers preferred the notion of a contractor certification program
until wood mid -rise construction becomes more common, and ideally
afterwards as well. The certification would apply to all trades working at
the site. An audit system to monitor the certification program was also
suggested.
❑ Regular progress reports on construction and loss prevention should be
posted to the company website.
An expected consequence of implementing such measures should be cost savings
through the ability to obtain the most competitive rates from insurance companies.
2.7 Innovation and Alternatives
New and emerging technologies, products and processes are continually being
developed to assist in construction site fire safety. While following established best
practices, those responsible for construction site fire safety should regularly
monitor industry news for innovations in this area.
Construction companies may also need to consider alternative approaches from
time to time to address creative building designs brought to them by architects and
engineers. An alternative approach should be discussed with local building
authorities and should be equivalent, as a minimum, to the code requirements in
terms of quality, strength, effectiveness, fire performance, durability and safety.

Definitions
Exposed combustible materials: Combustible materials that are not protected by
fire-resistant coverings (see below).
Fire-resistant coverings: Coverings applied to construction elements to increase
fire resistance, such as fire -rated gypsum board protecting timber or structural
steel.
Fire -preventative coverings: Coverings, screens or treatments to combustible
materials/construction elements that reduce the risk of ignition. Examples include
fire -retardant treatments and noncombustible sheathing.
Fire Safety Plan (FSP): A strategy document developed and implemented by the
owner of a construction site to address fire prevention, occupant safety, and fire
control and extinguishment.
Fire watch: Typically consists of a trained person with a fire extinguisher whose
sole job during the fire watch period is to guard against any fire ignition as a result
of hot work activity.
Hot work: Operations including cutting, welding, brazing, soldering, grinding,
thermal spraying, thawing pipe, installation of torch -applied roof system or any
other similar activity involving an open flame, sparks, friction or other heat or
ignition source.
Hot work area: The area exposed to sparks, hot slag, radiant heat or convective
heat as a result of hot work.
Hot work equipment: Electrical or gas welding, soldering or cutting equipment
used for hot work.
Hot work permit: Permits issued by the responsible person at the facility that
permit welding or other hot work to be performed and that outline requirements
to meet for the work to be permitted to take place.
14
Hot work program: Allows approved personnel to oversee and issue permits for
hot work conducted by their personnel or at their facility. The intent is that trained,
on-site, responsible personnel ensure that the required hot work safety measures
are taken.
NFPA Standard: A standard developed by the National Fire Protection Association
(NFPA), an organization that creates and maintains fire protection standards and
codes for use and adoption by local governments. Although based in the United
States, many NFPA standards and codes are widely adopted for use in Canada.
Pre -fire or pre -incident plan: A strategy document and site map indicating all
hazards and resource locations related to a property before a fire takes place, to
improve the effectiveness of the fire response.
Personal protective equipment (PPE): Equipment worn to protect human safety,
such as hard hats, safety vests, goggles and appropriate footwear.
Torch -applied roof system: Bituminous roofing systems using membranes that are
adhered by heating with a torch and melting an asphalt back -coating instead of
mopping hot asphalt for adhesion.

Fire Basics
4.1 Fire Theory
Fuel, heat and oxygen must be
present in the right proportions
for a fire to occur. This is often
described as the "fire triangle."
A&
Chain
reaction
The addition of a fourth
component, a chemical chain `
reaction, creates what is called
the "fire tetrahedron." Once a fire
has started, the resulting chain
reaction sustains the fire until at least one of the elements is removed.
Below are some of the common causes of fires at construction sites.
-Wim
• Normal atmosphere is
21% oxygen
• Additional oxidizers
4.2 Heat Transfer
• Combustible waste
• Building materials
• Flammable
gases/liquids
• Packaging materials
• Smoking materials
• Open flames
• Electrical equipment
• Light fixtures
• Grinding/cutting
metal
Heat from a fire can be transferred by three methods: radiation, conduction and
convection. In a typical building fire, solid and liquid matter are converted to gases
by heat, and additional heat (thermal energy) is released as the volatile gases are
consumed through the process called burning.
16
Radiation
Thermal energy in the form of electromagnetic waves is called radiation. Hot solid,
liquid or gaseous materials radiate heat that is absorbed by other materials.
Radiation is probably the most typical method of heat transfer from building to
building. Radiated heat can result in ignition of surface materials at some distance
from the originating fire, causing what is called an exposure fire.
Radiation can also be the main driver of "flashover" in a room or compartment —
that is, the transition from localized burning (for example, of a single object) to the
burning of all fuel surfaces in a room or compartment. This most often occurs when
the heat in a layer of smoke and gases near the ceiling radiates to all other surfaces
in the room. When the amount of radiation reaches a critical point, all exposed fuel
surfaces ignite.
Conduction
In conduction, heat is transferred molecule to molecule through the length of a
solid conductive material, such as metal. The fire may follow the heat, or
conducted heat may cause another fire to ignite. Conduction does not typically
cause fires to spread between buildings, but it can sometimes contribute to
spreading a fire within a building.
Convection
Convection is the most typical heat transfer method when it comes to spreading
fires within a building. Convection is the transfer of heat from one place to another
by the movement of fluids or gases. In the case of a building fire, heat is transferred
by the movement of air, including the fire -generated smoke and other gases.
Radiation as well as convection can prevent firefighters from getting close to the
seat of a fire.
4.3 Fire Types
Fires are classified according to the nature of the material being burned (the fuel),
and whether live electrical equipment is present. The primary purpose for
classifying fires is to identify the type of material required to extinguish them.
Fire types are grouped below based on fuel sources:
• Class A: Ordinary combustibles such as paper, wood, cloth, etc.
• Class B: Flammable and combustible liquids and gases
• Class C: Electrical fires
• Class D: Combustible metals
• Class K: Flammable cooking oils
4.4 Firefighting Methods
The method of fighting a fire depends on the fuel and on the presence of electrical
hazards. In general, there are three approaches to putting out a fire:
• Starvation: Cutting off the fuel supply, such as by removing combustible
materials;
• Smothering: Separating the fuel from the oxidant, such as by using a fire -
retardant blanket to smother flames; and
• Cooling: Lowering the temperature below the material's ignition
temperature, such as by applying water.
Fire extinguishers tend to either smother or cool the fire, depending on the type of
fire. Small fires can also be smothered by fire blankets or by sand or earth, which
are often in good supply at construction sites.
4.5 Fire Extinguisher Types
The nature of the fuel source and its reaction to extinguishing agents dictate the
type of extinguisher to be used. It is important to understand the different types of
extinguishers, because using the wrong agent — such as putting water on a
flammable liquid fire or electrical fire — can be highly dangerous and can even help
spread the fire.

4.6 Fire Extinguisher Use
1. Call for help before attempting to extinguish a fire. The fire may grow
much faster than you're capable of dealing with, and if help is on the way,
it removes one less concern for you.
• Call, or have someone else call, 911.
2. Ensure your own safety before trying to extinguish a fire — make sure you
have a safe way out. Before using a fire extinguisher, always:
• Assess the fire size — is it small enough to be put out by an
extinguisher?
• Check that you have the right type of extinguisher for the type of fire
(see chart above). For example, never use a water extinguisher on an
electrical fire.
• Ensure you feel confident that you can use the equipment properly.
• Check to see if the fire extinguisher is charged.
3. Ready the fire extinguisher. Almost all fire extinguishers have a safety pin in
the handle. This pin usually looks like a plastic or metal ring, sometimes
coloured red, which is held in place by a plastic seal. The seal needs to be
broken and the pin pulled.
4. Aim for the base of the fire. Shooting into the flame is a waste of the
extinguishing agent, as you're not addressing the source of the flames.
5. Use the PASS method:
• PULL out the safety pin
• AIM at the base of the fire
• SQUEEZE the trigger
• SWEEP the base of the fire
Keep in mind:
• Do not let the casing of the extinguisher come into contact with
energized electrical equipment.
• If the fire contains loose particles or involves lightweight materials or
liquids, be careful not to spread the fire with the blast of the agent from
the nozzle.
• A typical fire extinguisher will contain around 10 seconds of
extinguishing agent.
6. If you have successfully put out the fire, tend to the area and make sure
not to leave it alone, as it might re -ignite without warning.
7. Replace the used fire extinguisher. The used one is now depleted and will
serve no further purpose. Leaving it in place will create a false sense of
security.
Remember: If you have used an extinguisher, it MUST be recharged. Also,
follow your local fire code requirements for servicing fire extinguishers.
Typically, most require annual servicing.

Managing Risks
5.1 Construction Site Dangers
It is no surprise that a construction site can quickly become a dangerous
environment. The presence of hazardous and combustible materials, the use of
equipment that generates heat and sparks, lack of completed built-in fire -safety
systems or fire separations, and potential security issues are among the hazards.
The leading causes of fire in buildings under construction or demolition are:
incendiary or suspicious events, smoking, open flames (e.g. from hot work), embers
and heating equipment. Best practices to address the following common hazards
can be found in the Fire Prevention and Protection Best Practices section of this
guide:
• Waste
• Gases, solvents and many paints and adhesives
• Gas cylinders
• Electrical equipment
• Smoking on site
• Escape routes
• Temporary buildings
Through careful risk assessment, design and planning, hazards can be addressed
well before the first shovel goes in the ground.
5.2 Fire Prevention Planning
Fire prevention planning, which includes the development of a formal Fire Safety
Plan (see next section), should be completed before the project begins.
Steps to ensure success include:
❑ Assessing risks by asking questions such as:
o Where are fires most likely to occur?
o Are employees properly trained to identify and prevent conditions
that may lead to fires, and react appropriately if a fire starts?
o Are means of egress (exiting) kept clear of obstruction?
20
❑ Identifying and implementing actions to address the risks, such as
employee training.
❑ Communicating the plan to everyone involved in the worksite (including
management, contractors and employees) through written policies and
procedures, signage and information/training sessions.
❑ Continually evaluating and revising the plan to keep pace with the constant
changes at a construction site, including:
o New contractors or employees;
o Changes in types and quantities of materials;
o Changes in water supply; and,
o Deliveries or completed work that blocks evacuation routes.
❑ Maintaining accurate records and keeping them available for inspection by
fire authorities.
❑ Ongoing training and drilling to keep the information top -of -mind among
those at the worksite, and to solicit input for improvements. Tactics can
include weekly walk-throughs and "toolbox talks."
5.3 Project Staging
Strategic project staging can significantly reduce the fire risk at construction sites.
Elements for consideration are as follows.
❑ Coordinate the installation of some or all fire protection equipment (such
as standpipes, hose stations, sprinkler systems and alarms) in stages to
provide active fire detection, control and/or suppression in sync with the
development of the structure itself.
❑ Prioritize the installation of fire barriers, separation walls and fire doors on
each floor, and time them to progress in step with structure development.
Fire doors should be installed at the same time as their frames.
❑ Fire blocking should be installed immediately where necessary, and smaller
openings identified, marked and scheduled for fire stopping as soon as the
section is completed.
❑ Any noncombustible finishes, both internal and external, should follow in
stages as the project progresses.
❑ Consider alternate construction materials and methods to reduce fire risks,
such as:
o Using five-ply built-up roof coverings instead of single -ply
membrane roofs, to avoid the need for hot work on the roof; and
o Using panelized wall and floor assemblies constructed off-site,
rather than site -built assemblies, to reduce the amount of stored
on-site combustibles and construction time.
PAI
Developing a Fire Safety Plan
Fire safety plans (FSPs) are designed to address typical construction hazards and
are usually developed by the site owner/developer or their representative in
conjunction with the local fire department. FSPs are required by the National
Building Code of Canada and most provincial building or fire codes for construction
projects of a certain size or type. Check your locally -applicable building and fire
codes for guidance about FSP requirements.
Owners may choose to obtain the services of a fire -safety planning specialist to
ensure they develop an adequate plan for their site. This job may also be tasked to
a site fire prevention/fire safety manager.
6.1 Site Fire Safety Manager
A site fire safety manager with adequate training and knowledge should be
appointed to manage and enforce the FSP throughout the course of the
construction project.
Responsibilities will vary based on site size and complexity, but generally include:
❑ Conducting daily inspections to identify fire hazards and security issues,
and developing measures to address them.
❑ Liaising with the fire department.
❑ Ensuring everyone at the site is aware of and understands their
responsibilities under the FSP (methods could include signage, training,
drills, and stipulations in contracts for subcontractors).
❑ Ensuring compliance with the FSP and taking action to address infractions.
❑ Carrying out daily inspections of:
o Evacuation routes, fire safety signage and temporary emergency
lighting (where applicable);
o Installed fire detection and alarm devices;
o Firefighting equipment/facilities and fire department access; and
10%
o Routing of temporary electrical cables, housekeeping and
combustible waste storage.
❑ Taking prompt, effective and appropriate action if fires occur, including:
o Raising the alarm to alert others of the fire;
o If trained, tackling small fires before they spread;
o Ensuring all staff, visitors and contractors are evacuated to a place
of safety; and
o If time permits, closing doors and windows as people leave, to slow
fire spread.
❑ Maintaining accurate records of site inspections, infractions and other
documentation related to the FSP for management and fire authorities.
❑ Updating evacuation routes and other elements of the plan as necessary as
conditions at the site change.
Depending on the size of the project, the site fire safety manager may require
support from another designated individual or team.
6.2 Plan Components and Implementation
FSPs should be updated after any significant project changes. While plans will vary
based on the project size and complexity, at minimum, each FSP should include:
❑ The designation and organization of site personnel responsible for fire
safety duties;
❑ Emergency procedures to be followed in the event of a fire, including
sounding the alarm, notifying the fire department, instructing site
personnel on the procedures to be followed when the alarm sounds, and
firefighting procedures;
❑ Measures for controlling fire hazards in and around the building;
❑ A maintenance procedure for firefighting facilities;
❑ Documents and diagrams showing the type, location and operation of the
building's fire emergency systems; and,
❑ A list of all emergency response numbers and the names, addresses and
telephone numbers of the project's emergency contacts.
Relevant Activities
Activities that may be critical to the success of a FSP include:
❑ Fire safety training, including:
o Instruction in fire prevention and evacuation procedures for all
workers.
o Adequate training (and retraining) for workers assigned to
firefighting duties by a qualified instructor in fire suppression
methods, fire prevention, emergency procedures, organization and
chain of command, firefighting crew safety and communications.
o Ensuring all workers assigned to firefighting duties are physically
capable of performing the duties safely and effectively.
❑ Passive protection, including:
o Provision on each level of an unobstructed stair discharging to
grade level.
23
o Coordination between the construction of fire compartments and
firewalls.
o Management of fuel -fired equipment, including limiting usage and
using electrical -powered alternatives when possible.
o Management of temporary heating equipment, such as ensuring all
are listed and used in accordance to manufacturer instructions.
o Management of roofing operations involving heat sources and hot
work, including having operations conducted by a qualified agency.
o Maintaining a high standard of housekeeping on site.
o Maintaining fire department access to the site.
o Providing a fire separation between occupied areas and areas
under construction or demolition.
❑ Fire protection, including:
o An activated (charged) standpipe installed progressively with
building construction.
o Where and when practicable, an activated (charged) sprinkler
system upon installation of the ceiling membrane. When possible,
the system should be activated when construction is not taking
place but may be turned off during operating hours.
o Onsite fire protection stations that may include portable fire
extinguishers.
o Early installation of fire pumps where required for the fire
protection water supply.
o Coordination such that the municipal water supply is available
onsite when grade -level construction begins.
o A fire alert warning system.
o Temporary heating equipment that complies with the fire code.
❑ Security and monitoring, including:
o Alert, roving after-hours security personnel.
o A fire watch during hot work operations and for at least 60 minutes
afterwards, and again four hours after completion.
o A watch during demolition or construction involving partially
occupied buildings.
Additional recommended activities may include:
❑ Installing doors in firewalls and closing them after hours, and putting doors
on fusible links during construction.
❑ Providing temporary water -flow alarms on sprinklers.
❑ Providing adequate timing for issuance of the sprinkler permit, given that
sprinkler drawings must be reviewed by numerous consultants and
accepted by municipal authorities.
❑ Providing sprinkler systems for exposure protection.
❑ Holding a pre -construction meeting between the local fire department and
site representatives.
❑ Development of a fire risk assessment for more complex sites that
identifies time frames and processes where the risk is greater and extra
measures may be required.
Your local fire department may have a checklist to assist with FSP development.

Site Security
Security is required on a construction site for many purposes, including preventing
arson, theft and unauthorized entrance.
Security measures may include:
❑ Erecting secure fencing, boarding or hoarding at least 1.8 metres in height
around the perimeter, with access gates that can be closed and locked.
❑ Setting up security access points at site entrances, including entries to the
construction zone in occupied buildings.
❑ Maintaining strict sign-in/sign-out procedures for anyone gaining access to
the site, including visitors, contractors and the permanent workforce (sign -
in sheets are also useful for tracking occupants if evacuation is required).
❑ Employing 24-hour guards on larger or more hazardous sites, with orders
that include recorded rounds, supplemented by intruder alarms.
❑ Storing combustible materials and potential ignition sources in secure areas,
away from the perimeter and at least 10 metres from the building.
❑ Emptying dumpsters regularly and locating them away from buildings, and
far enough from the perimeter to prevent deliberate ignition from outside
the boundary.
❑ Storing expensive equipment and vehicles in a secure area when not in use.
❑ Installing security lighting, closed-circuit cameras and intruder alarms.
❑ Instituting a rigorous locking -up procedure that includes making sure all
gates, doors and equipment are secure, and checking hot work areas for
signs of fire.
Site security is everyone's responsibility. Personnel should be advised to:
❑ Watch for and report any damage or signs of tampering with perimeter
security, lighting or security cameras.
❑ Report anyone who does not seem to belong on the site. Security
personnel should question any unknown or suspicious individuals.
7.1 Security Guards
A security guard service may be required, depending on the size and physical
configuration of the site. Orders for the guards should, at minimum, include:
25
❑ Notification procedures that include calling the fire department and
management if an event occurs;
❑ Knowledge of the building street address;
❑ Knowledge of location and use of fire extinguishers and fire control
equipment;
❑ Familiarization with fire hazards; and
❑ Use of the construction elevators, if any on site.
Site security should be issued adequate equipment to enable them to immediately
notify the fire department using the emergency phone number if the need arises.

8.1 Electrical Supplies and Equipment
❑ All electrical systems and equipment, including temporary installations,
should be installed and maintained in accordance with applicable
regulations by a qualified technician. Poor installation and maintenance can
lead to a buildup of heat or arcing and sparking, all of which have the
potential to ignite any nearby combustibles.
❑ Electrical equipment, including portable devices and electrical cords,
should be regularly maintained and inspected as part of day-to-day
routines, and any problems should be reported and fixed immediately.
❑ Faulty or damaged equipment should be removed from use immediately,
labeled, and either removed from the site or secured to prevent future use.
❑ Any equipment that operates at temperatures above 75°C should be
securely fastened to prevent hot parts of the equipment from coming in
contact with combustible materials.
❑ Fragile components, such as temporary lights, should be equipped with
guards to prevent accidental damage.
❑ Low -voltage equipment should be used when possible.
❑ Electrical cabling, especially temporary installations, should be protected
against damage from construction activities.
❑ Temporary wiring should be removed as soon as it is no longer needed.
❑ When using metal halide lights for temporary lighting, only use fixtures
equipped with Type O lamps. Any other type of lamp could present a
severe fire risk if it fails prematurely. Combustible and flammable materials
should not be stored directly below the light fixture in the event of a
catastrophic light failure.
❑ Special consideration should be given to equipment located near storage of
flammable gases or liquids.
❑ Where possible, main switches (other than those controlling security and
automatic fire detection systems) should be turned off when work ceases,
and all equipment unplugged when not in use.
Please see Heating Equipment below for related information.
8.2 Emergency Procedures
Please see Evacuation and Egress and Fire Alarm Systems below for related
information.
Preparation
General
❑ Clear signage should be provided and maintained in prominent positions
showing the locations of fire department access routes, escape routes,
standpipes, and fire extinguishers provided for use by trained staff. Signs
should be reviewed regularly and replaced or repositioned as necessary.
❑ Assembly points should be designated in advance and clearly identified.
❑ Employers should provide training on emergency procedures, including
how to raise the alarm to all workers at the site. Drills should be conducted
to test the procedures and ensure workers and supervisors are familiar
with their roles and responsibilities.
❑ Security personnel should be instructed to open gates or barriers and
provide ready access to the fire department in the event of an emergency
or an inspection visit.
Written Procedures
Written emergency procedures should be displayed in prominent locations and
given to all employees and visitors on site.
The procedures should include:
❑ Emergency contact details for key personnel who have specific fire or
safety roles or responsibilities;
❑ Contact details for local emergency services such as police, fire department
and poison control;
❑ Description of the mechanisms and procedures for alerting people on site
about an emergency or possible emergency, such as a siren or bell alarm;
❑ Evacuation procedures, including arrangements for assisting any people
with hearing, vision or mobility impairments;
❑ Map of the site illustrating the location of fire protection equipment,
emergency exits and assembly points;
❑ Triggers and processes for advising neighbouring businesses/residents
about emergencies;
❑ A post -incident follow-up process, such as notifying regulatory agencies
and organizing trauma counseling or medical treatment; and
❑ Procedures for testing the emergency plan, including frequency of testing.
During emergencies
❑ Employees discovering a fire should sound the fire alarm and notify all
employees in the immediate vicinity, as well as surrounding areas that may
be threatened by the fire.
❑ Employees should then immediately notify the fire department of the fire.
❑ The supervisor or designated individual should also be notified of the fire
immediately.
❑ Employees discovering a fire should, if possible, quickly and carefully
remove anyone who is injured or in immediate danger.
❑ If the area or material involved in the fire is small, properly trained
employees may attempt to extinguish the fire using approved fire
suppression equipment.
❑ If the fire appears to be too large, involves a toxic substance, or is
electrical -based, employees should leave the area immediately and notify
their supervisor.
8.3 Equipment and Vehicles
❑ No vehicles should be parked inside of buildings unless fire -detection
systems are installed and monitored.
❑ No mobile construction equipment should be stored inside of buildings
without first making sure the equipment has cooled down and there are no
leaks in the fuel or hydraulic systems.
we
❑ Equipment and vehicles should be located so their exhausts discharge as
far as possible away from combustible materials (not less than 500 mm).
❑ Combustible materials should be prevented from coming into contact with,
or being close to, hot surfaces such as flues and exhaust pipes.
❑ Fuel storage and service areas should not be located within structures
under construction, alteration or demolition.
❑ Policies for the refueling of tools and equipment should require that the
appliance be cool before refilling.
❑ Where appropriate, sand trays should be provided to absorb drips of fuel
or lubricant. The trays should be changed at regular intervals.
❑ As a general rule, long-term parking of vehicles should not be permitted
within 10 metres of a building under construction, and, if possible, a
separate parking lot should be available for workers' vehicles.
8.4 Evacuation and Egress
Preparation
❑ Adequate paths of travel to exits and evacuation routes should be provided
at all times, taking into account the number of people, activities being
undertaken, and occupant capabilities. Routes should also be designated
through large open-plan areas.
❑ Two ways out should be provided whenever possible, particularly if
working at height or below ground level.
❑ Multi-storey projects that have progressed to 10 metres or more above
ground level should have permanent or temporary stairs to the ground that
are accessible from each working level.
❑ Signage showing the fastest way out should be clearly visible, and should
be regularly monitored and relocated as necessary as construction
progresses and conditions change.
❑ Regular checks should be undertaken to ensure exits and evacuation routes
are kept clear of obstructions and provided with clear signage. These
checks should be undertaken daily or weekly, depending on the risks
associated with the site.
❑ Combustible materials and liquids should never be stored in an evacuation
route.
❑ Building exits should never be blocked or locked while people are in the
buildings.
❑ Staff should be advised to make themselves aware of escape routes and
that routes could change without notice.
During emergencies
❑ An assembly site away from the premises should be designated in advance
and communicated to everyone on the site. If acetylene cylinders are
stored on site, the assembly site should be at least 200 metres away from
the location of the cylinders.
gill
❑ Once a fire alarm has been raised, the fire department should be contacted
and all occupants should evacuate the building and/or worksite and make
their way to the assembly site, ensuring that fire service access points are
not obstructed.
❑ If the building fills with smoke, occupants should stay low and follow the
wall, if possible, as they exit.
❑ A designated person should confirm that all occupants have been
accounted for (using documentation such as sign -in sheets, employee lists
and work schedules), and provide the information to the fire department. It
is important that the fire department know if anyone may be in the
building, so a system to track site occupants at all times is critical.
Temporary Exiting
❑ Existing exits should not be impaired or impeded by new construction. In
the event that temporary exiting is required, blocked exits should be
minimized.
❑ Temporary floor signs should be provided in any stairwell connecting three
or more floors, indicating the floor number, roof access and direction to
exits.
❑ If the building is over one storey in height, at least one stairwell should be
provided that is in usable condition at all times.
❑ A stairwell should be extended upward as each floor is installed with new
construction.
8.5 Fire Alarm Systems —Temporary
It is everybody's responsibility to immediately raise the alarm in cases of fire or
other emergency on a site.
Where the installation of permanent automatic detection and alarm systems is not
practical during construction, a temporary means of fire warning should be
established to allow staff to raise an alarm across the site if a fire is detected, and
to alert the fire department.
Manual devices (such as hand -crank alarms and air horns) may be utilized, provided
that:
❑ They are distinctive and clearly audible above background noises in all
areas;
❑ All staff and inducted visitors are trained/instructed so that they can
recognize the fire/emergency alarm and understand what action to take;
and
❑ The devices are distributed throughout the site, and staff are aware of their
locations and trained in their use.
Telephone systems can be used to alert the fire department, provided the
emergency procedures adequately specify responsibilities for alerting the fire
department, and emergency numbers are prominently displayed along with the
site address.
911
Emergency phones, when provided, should be located at strategic points and
clearly identified.
8.6 Fire Extinguishers
See the Fire Basics section for information about fire extinguisher types and use.
❑ Extinguishers should be installed in unobstructed and easily accessible
locations in accordance with NFPA 10 Standard for Fire Extinguishers. They
should be installed on each storey, adjacent to each required exit,
temporary exit or stairway, and near areas where combustibles are stored
and hot work is carried out.
❑ At least one Class A, B and C fire extinguisher of the appropriate size should
be provided at all times.
❑ Ride -on mechanically -propelled equipment should carry an appropriate fire
extinguisher when possible.
❑ Employees should be made familiar with the location of all fire
extinguishers on site.
❑ Extinguishers should be provided for fire watch personnel while hot work is
being undertaken, and at any other locations identified through risk
assessments or required as part of a standard safe work method.
❑ Fire extinguishers should be maintained and regularly inspected, and staff
should be trained in the use of manual firefighting equipment.
❑ As construction progresses, the adequacy of portable firefighting
equipment should be reviewed as part of the periodic site fire assessment.
8.7 Fires — Open and Waste Fires
❑ Open fires, including the burning of waste materials, should be prohibited
on the construction site. Combustible waste materials should be regularly
removed from the site rather than burned.
❑ Use of warming devices, such as heating drums, should be located outside
of any structure. If they are intended to be used, a risk assessment should
first be undertaken.
8.8 Fire Protection Systems
When the following fire protection systems are to be installed in the completed
building, the project should be planned to bring them into operation as early as
possible during the course of construction.
Automatic Fire Sprinkler and Other Suppression Systems
❑ When possible, automatic fire sprinkler systems should be progressively
brought into service on each floor as construction takes place.
❑ Early installation is particularly important when the building design relies
on a sprinkler system to supplement fire separations (e.g. waiving
requirements for spandrels or reducing fire -resistance levels) or to control
fire spread when combustible materials are exposed during construction.
Kia
❑ Progressive installation may not be practical in colder regions during the
winter, due to the lack of insulation or heating in the unfinished buildings.
❑ There is potential for damage to sprinklers from nearby construction tasks
when installation is performed before the building is completed, so special
care and/or replacement of damaged components may be necessary.
Automatic Fire Detection and Alarm Systems
❑ When possible, fire detection and alarm systems should be brought into
service progressively on each floor as construction takes place.
❑ There is potential for damage to these systems from nearby construction
tasks when installation is performed before the building is completed, so
special care and/or replacement of damaged components may be
necessary.
Fire Compartment Boundaries
Fire compartment boundaries include fire doors, penetration seals and general
protection of other openings.
❑ Fire compartment boundaries should be completed progressively
throughout the project to minimize fire spread.
❑ Where the provision of fire compartments is critical to fire safety during
construction, temporary coverings of openings should be provided while
ensuring exit paths are not compromised.
Other Forms of Fire Protection
❑ Fire stairs with fire-resistant walls.
❑ Planned firefighting shafts.
❑ Fire -protective materials applied to structural steel.
❑ Fire -preventative coverings, such as fire blankets, used over combustible
construction.
8.9 Food Preparation
❑ Food preparation that involves the use of open flames should be prohibited.
❑ Areas should be designated where meals can be warmed using a
microwave or other forms of non -flame -producing heat.
❑ Cooking appliances should be properly installed, with adequate ventilation
provided.
8.10 Flammable and Combustible Building Materials
❑ Deliveries of wood framing and other combustible materials should be
planned to minimize the time they are stored on site.
❑ Combustible building materials and scrap lumber should be stored in a
secure area at least 22 metres away from any buildings or partially
constructed buildings, or any area where hot work is undertaken.
❑ When not in use, mops used to spread bitumen for hot surface applications
should be stored in a safe location at a safe distance away from buildings.
33
❑ If there is no alternative to storing combustible building materials within or
close to a building under construction, the storage area should:
o Have controlled access;
o Not be in an area where hot work is being carried out;
o Be in either an area covered by the site fire -detection system or
included in the route of regular fire checks;
o Have firefighting equipment close by; and
o Be protected from ignition sources where practical by fire -
preventative covers.
8.11 Flammable and Combustible Liquids and Gases
The storage and use of flammable liquids and gases require specific safety
measures that address the risks of use in confined spaces and potential explosions,
in addition to normal fire risks. Refer to the applicable federal or provincial
legislation.
This category includes common fuels (e.g. gasoline and liquid propane gas) and
acetylene used for cutting purposes. Typical requirements are found in various
NFPA standards.
Some of the main fire prevention methods are as follows:
❑ Gas -line purging requirements:
o Gas lines should be purged to the outdoors.
o Gas lines should be continuously monitored to the point of
discharge. If done indoors, a combustible gas detector should be
used to monitor the point of discharge.
o Ignition sources should be kept at least three metres away from
the point of discharge.
o The discharge point should be at least three metres from openings
and eight metres from any intakes.
o Any non -purging employees should be evacuated.
o Purging should be stopped when 90 per cent gas volume is reached.
❑ Workers should be instructed and trained in the storage and handling of
flammable and combustible liquids and gases.
❑ Storage of flammable liquids and gases should be limited to a day's supply.
❑ When not in use, flammable liquids and gases should be stored in closed,
clearly labeled containers/cylinders compliant with NFPA standards, in a
secure area — preferably an open compound at least 10 metres from
permanent and temporary buildings and 20 metres from structures
fabricated predominantly with combustible materials.
❑ In enclosed settings, care should be taken to avoid buildup of explosive
fumes.
❑ Automatic flammable -gas detection equipment should be considered for
enclosed storage areas.
❑ All electrical fittings in storage areas, such as lights and switches, should be
suitable for an environment where a flammable or explosive atmosphere
may be present.
MA
❑ All sources or potential sources of ignition should be eliminated or
controlled where an explosive atmosphere exists or is likely to exist.
❑ Flammable liquids and gases should be stored separately from materials
that could intensify the fire or present a toxic hazard, such as oxygen,
acetylene and chlorine.
❑ Flammable liquids, compressed gases and/or liquid propane gas should not
be stored together.
❑ Empty and full gas cylinders should be separated, and empty cylinders
marked to allow staff and firefighters to identify them easily.
❑ Clear signage should be provided identifying the materials being stored and
prohibiting smoking, open flame, hot work and the use of mobile phones in
and around the storage area.
❑ The use of acetylene should be minimized and spare cylinders should not
be kept on site. As soon as the work is completed, acetylene cylinders
should be returned to the storage area.
❑ Leaks or spills should be dealt with promptly and safely.
❑ Flammable liquids should never be used when there are open flames or
sources of ignition nearby. For example, fuel tanks of heating devices
should never be refilled while the device is in operation or is hot enough to
ignite the liquid.
❑ Propane cylinders should not be placed closer than three metres to a
source of ignition unless they are part of hand-held equipment, part of a
lead pot used in plumbing or electrical work, part of a propane -powered or
propane -heated vehicle, or are protected by a barrier, wall or other
separation.
❑ The accumulation of static charge during the transfer of flammable or
explosive substances from one container to another should be prevented
by electrically bonding the containers.
❑ Liquids should only be used for their intended purposes. For example,
gasoline should not be used to start a fire or used as a cleaning agent.
❑ Proximity to flammable liquids and gases should be considered in hot -work
risk assessments.
8.12 Flammable and Combustible Materials — Other
During construction, combustible materials may be temporarily in place or exposed
in locations such as the fagade or as parts of wall or ceiling linings. These include:
❑ Shade cloths, tarps and other covering around scaffolding, separating work
areas, and around the site perimeter;
❑ Scaffolding components;
❑ Combustible facade materials, including insulation;
❑ Piping, wiring, and other service elements; and,
❑ Wood framing members and sheathing.
Additional precautions may be required during the construction phase if a risk
assessment determines the volume of exposed combustible materials is significant.
The risk assessment should consider the proximity of the incomplete building to
surrounding buildings, as well as fire safety within the site.
35
Mitigation measures to consider include:
❑ Shade cloths, tarps and other temporary coverings should be fabricated
from noncombustible materials or fire -retardant materials when possible,
and should be securely fastened to prevent contact with heaters or other
ignition sources.
❑ For buildings of four or more storeys, if the incomplete, exposed facade is
combustible, or if the building is predominantly of combustible
construction, consider one or more of the following controls:
o Exposed combustible construction materials could be progressively
clad with the coverings required by the final design (e.g. interior
gypsum board, gypsum sheathing, and exterior cladding) so that
there are only two storeys below the current construction level
with significant exposed combustible materials.
o If an automatic sprinkler system is to be provided, it could be
progressively commissioned so that there are only two
unprotected storeys with significant combustible materials below
the current construction level.
o Early installation of permanent or temporary fire compartments
can limit fire spread in the event of an uncontrolled fire. Protection
of door openings, windows, shafts and service penetrations needs
to be addressed.
o A temporary fire alarm system could be provided and evacuation
procedures modified to address the expected rate of fire spread.
o Separation distances or fire barriers may be needed between
adjacent buildings and the building under construction, as
appropriate to the fire hazard.
8.13 Heating Equipment
❑ Any heating equipment should, as a minimum, comply with provincial and
local regulations and be installed, used and maintained in accordance with
the manufacturer's instructions.
❑ Heating equipment should not be used in close proximity to combustible
materials.
❑ Personnel should always be required to be in attendance when the heater
is running.
❑ The heating device should be restrained to minimize the risk of it being
knocked over or being incorrectly located.
❑ Heating equipment should be regularly inspected.
❑ Heaters should not be covered with wet or damp clothing. Coat stands and
drying racks should be fixed in place a safe distance from heaters.
❑ Paraffin or gas heaters should be avoided where possible.
❑ Where possible, a system planned so that heating equipment remains
outside the building(s) under construction should be considered.
❑ Heaters used in temporary buildings should have enclosed elements, be
fixed in position (preferably above floor level), be thermostatically
controlled, and be maintained in sound condition.
Please see Electrical Suoolies and Eauioment above for related information.
8.14 Higher -risk Sites
Additional measures are warranted for construction of tall buildings where the
upper storey is above the reach of external firefighting equipment, or buildings of
predominantly combustible construction that have four or more storeys or a floor
area of more than 2,500 square metres.
All Tall Buildings
❑ A wet standpipe riser should be provided, fed by duplicate pumps.
❑ Fire doors with self -closers should be fitted to protect the escape stairs and,
where possible, access to any shaft in which a crane is located.
❑ The building should be horizontally compartmented at intervals not
exceeding 10 storeys, to prevent the spread of smoke and flames. This
should be done at the earliest opportunity after construction of each of the
relevant floors, using temporary fire -stopping materials with at least one-
hour fire resistance, until the permanent fire -stopping arrangements can
be put in place.
Large or Tall Building Sites with Combustible Construction
❑ The building should be compartmented at the earliest stage possible. For
example, fire-resistant sheathing required by the final building design
should be fixed in place as soon after the erection of each storey as is
practicable.
❑ To retard the spread of fire up a building through unstopped ducts and
shafts, consideration should be given to installing temporary fire -retardant
boarding as work progresses.
❑ Permanent fire -resisting doors, panels and fire stopping should be installed
as early as possible.
❑ The proximity of the incomplete structure to the site boundary and
surrounding buildings should be considered during the fire risk assessment.
❑ Serious consideration should be given to mitigating fire damage by facing
exposed wood construction and combustible insulation with
noncombustible or limited -combustible materials at the earliest
opportunity. The use of such materials may be extended to protect
windows and door openings not required as means of escape.
❑ Consideration should be given during the fire safety planning process to
evacuation routes for site personnel, including crane operators.
❑ Even when the perimeter of the site is secure, access to the building under
construction should be denied when work is not in progress.
❑ When multiple large structures constructed predominantly of combustible
materials are being built close to each other, the hazards of fire spread
from one to another should be considered and minimized as part of the fire
risk assessment.
8.15 Housekeeping
'Housekeeping' involves keeping the worksite tidy and safe, ensuring combustible
materials are stored in safe designated areas, as well as spotting hazards and taking
action against them.
37
Housekeeping is an important fire -prevention practice, but it can quickly
deteriorate as a result of lack of action from supervisors. Housekeeping needs to be
enforced consistently and action taken when rules are violated.
Proper housekeeping includes:
❑ Keeping the premises clear of all kinds of refuse and process waste.
❑ Ensuring waste and excess debris or scrap is swept up and removed from
the premises at least daily.
❑ Ensuring all areas in and around the building site are kept free from
accumulated packing materials, such as empty wooden crates, straw,
plastic products, paper, etc.
❑ Ensuring appropriate metal bins (or dumpsters with lids for some items)
are provided for disposal of combustible waste materials such oily rags;
❑ Keeping storage areas accessible to firefighters.
❑ Clearing spaces around stacks of stored materials and ensuring adequate
gangways are present between them.
❑ If a sprinkler system is installed, arranging all stacks of material to ensure
they do not impede the effective operation of sprinklers.
❑ Locating dumpsters at least 15 metres away from the building (the farther
away, the better). If a dumpster is located within the footprint of the
building, then an on-site guard should be assigned or hired to monitor it.
8.16 Hot Work
Hot work — work that generates open flames, heat and/or sparks — is a common
cause of fires on construction sites. Hot work operations may include cutting,
welding, brazing, soldering, grinding, thermal spraying, thawing of pipe, and
installation of torch -applied roof systems.
When possible, activities involving hot work should be minimized or conducted off-
site in a dedicated hot -work shop.
When hot work on site is required, site managers are responsible for ensuring
adequate control and procedures are in place before work begins. A risk
assessment should be conducted that considers alternatives to hot work, the risk of
fire ignition, who will be in danger, and the possibility of fire spread.
Training
❑ Anyone performing hot work should be trained in proper equipment
operation, handling and storage of welding materials, compressed gas
safety, chemical hazards, and working procedures.
❑ Additional training may also be required in the proper selection and use of
specialized personal protective equipment.
❑ Training in confined space entry is necessary before any hot work is
performed in a confined space area.
❑ Anyone performing hot work should be trained in emergency procedures
such as how to raise the alarm, call the fire department, and safely
evacuate the area in the event of fire.
IN
Hot Work Permits
A hot work permit system is a useful fire -prevention tool even in jurisdictions
where they are not required, as they:
❑ Provide a checklist of activities that protect employee and site safety;
❑ Help ensure compliance with safe work procedures; and
❑ Ensure accountability that fire prevention measures are being considered
at all times.
Permits should be specific to the location, activity and work period, and should not
provide blanket coverage.
A permit checklist may include the following measures:
❑ Written permission should be obtained prior to starting any hot work
activity.
❑ All potential hazards should be described and accounted for.
❑ Hot work equipment should be regularly inspected and tested to ensure it
can be operated safely (e.g. power source, welding leads, torches, etc.).
❑ Combustible materials and liquids should be at least 10 metres away from
the hot work area. If they cannot be moved, they should be protected with
fire blankets, guards or metal shields.
❑ Floors in hot work areas should be swept clean of all combustible materials
and debris.
❑ Combustible floors and flooring (e.g. wood or carpeting) should be wet
down and covered with damp sand or fire blankets.
❑ Burning, welding or cutting should not take place where there is danger of
extreme heat coming in contact with a concrete surface, unless the surface
is protected from the heat source.
❑ All openings in floors and walls within 10 metres of a hot work area should
be covered to prevent hot sparks from entering, or falling to a lower level.
❑ If there is a danger of heat transfer to other areas (e.g. through metal
beams, bolts or pipes), those areas should also be cleared of combustible
materials.
❑ When working on walls or ceilings, combustible materials should be moved
away from the other side of the wall.
❑ Bitumen kettles should not be located on roofs, and should be provided
with a close -fitting metal cover. They should be under constant supervision
when in operation.
❑ Tar pots that are in use should not be placed within three metres of an
entrance or exit of a building or structure.
❑ Welding or cutting torches should not be laid down until the gases have
been completely shut off.
❑ Hot work should never be conducted in the presence of flammable or
explosive gases, vapours, liquids, substances or dust.
❑ Welding or cutting of metal that has been cleaned with a flammable or
combustible liquid should not be permitted until the metal has dried.
❑ Hot work should not be permitted on containers or piping that contained a
flammable substance until they are purged using an effective method.
❑ Appropriate fire extinguishers should be on hand, fully charged and
operable.
❑ Evacuation paths should be kept clear.
❑ There should be a means for communicating an alarm in the hot work area.
❑ A suitably trained and equipped person should be assigned to fire watch
during the hot work and stay on watch until released by the individual in
charge. Hot work areas should be monitored for at least an hour after the
work is completed, and checked again four hours later.
❑ In premises with heat or smoke detectors, only those adjacent to the hot
work area should be disabled, and should be reactivated immediately
afterwards.
❑ After hot work is completed, hot waste materials should be removed and
disposed of safely, and all equipment, including gas cylinders, should be
removed to a secure area. (If bitumen or tar boilers are involved, only the
gas cylinders need to be removed.)
❑ Hot work areas should be inspected at the end of the day by the
authorizing individual, and by security staff (if on site and it is reasonably
practicable and safe to access the area).
Please see Personal Protective Equipment for Hot Work below for related
information.
8.17 Hose Stations and Hose Reels
❑ All hose stations and hose reels required by code for the completed
building should be progressively installed on all levels of a building under
construction as early as possible, and unobstructed access maintained. As
well, they should be made fully operational as soon as possible.
❑ Hose stations should be installed for use both inside and outside the
building.
❑ Any required booster connections should be installed as early as possible.
8.18 Personal Protective Equipment for Hot Work
Personal protective equipment (PPE) guards employees against injury (which can
be fatal) and will vary depending on the type of construction activity.
The information in this section is specific to hot work. For other construction work,
please refer to and follow the PPE practices and guidelines applicable to your
region and type of activity.
Clothing and Equipment
❑ Protective clothing and equipment should be suitable for the type of work
to be performed, kept in good repair, and kept free of oil and grease.
❑ Sleeves should be kept buttoned at the wrist and collars should be kept
buttoned.
❑ Fire-resistant gauntlet gloves, aprons of leather or asbestos, and other
appropriate PPE should be used as protection against radiated heat or
sparks.
❑ Front pockets on overalls and aprons, and cuffs on pants, should be
eliminated.
❑ Capes or shoulder covers made of leather or other flame- and heat -
resistant material should be worn during overhead welding or cutting
operations.
❑ Leather skullcaps can be worn under helmets to provide protection against
head burns.
❑ When working in a confined space or an overhead location, earplugs should
be worn or the ears covered with wire screen protectors.
❑ Hard hats or other types of head protectors should be used where there is
exposure to falling objects or debris.
❑ Low-cut shoes should not be worn unless the ankles are covered with
protective leggings.
❑ Employees required to wear respirators should keep them clean and
sterilized after each use. When not in use, the equipment should be stored
in closed containers.
❑ The airline to supplied -air respirators should be provided with a filter that
will remove pipe scale, water, oil, mist, and noxious vapours. The respirator
should also be equipped with a pressure -reducing valve to prevent the
supplied -air pressure from exceeding 25 psi.
❑ Insulating mats of sufficient size should be used when the worker is sitting
on the same metal that is being welded.
❑ Rubber gloves should be worn under welding gloves when welding in wet
or damp locations.
❑ After a welding job is completed, the material should be marked "HOT" in
chalk, or a warning sign posted to caution other employees.
Eye Protection
❑ Goggles, helmets, hand shields, or other suitable eye protection with the
proper lens shade for the work at hand should be worn during all welding
or cutting operations.
❑ Goggles, helmets, and hand shields should be checked frequently.
Equipment with light leaks should not be worn, as radiation burns can
result. Cracked, broken, or loose filter plates should be replaced
immediately.
❑ Protective -coloured flash goggles with side shields should be worn under a
hood for protection against harmful rays, flying chips, and sparks when an
arc is struck prematurely before the helmet is lowered. The lenses should
be No. 1 or No. 3 shade. Inert gas metal -arc welding by nearby welders
requires goggles under the helmet with lens shade.
❑ When arc -welding operations are performed in an area that is not enclosed
or isolated, other persons near the welding area (generally within 23
metres of the arc) should wear appropriate goggles.
❑ Flash shields should be carried on portable welding carts as standard
equipment and should be used when necessary.
Please see Hot Work above for related information.
III
8.19 Protection of Adjacent Buildings
Protection of adjacent buildings and facilities that would be exposed to a fire
originating at the construction site should be assessed. Methods and materials
used to protect adjacent buildings and facilities may include active or passive
systems, such as:
❑ spatial separation,
❑ water curtains,
❑ fire-resistant construction methods and materials (such as gypsum
sheathing), or
❑ temporary fire barriers, such as fire tarpaulins.
The occupancy type of any adjacent building also should be considered during the
development of the fire safety plan.
8.20 Smoking
Smoking materials are a significant ignition source for fires on construction sites. All
employees and site visitors should be fully informed of site smoking restrictions,
and an emphasis placed on the fire safety reason for such restrictions.
❑ Smoking restrictions should be applied throughout a construction site
because hazardous materials, such as flammable liquids and gases, may be
used in open as well as enclosed areas.
❑ If designated smoking areas are to be provided on or adjacent to a
construction site, a specific risk assessment should be undertaken before it
is allowed.
❑ Smoking restriction zones should be clearly identified, signposted and
strictly enforced.
❑ Smoking areas should be constructed of noncombustible materials and be
separated from buildings by at least six metres (or more if determined
necessary by a risk assessment). Combustible curtains, canopies and drapes
should not be used to protect smokers from the elements.
❑ The immediate area should be kept clear of combustible materials,
including windblown debris and vegetation.
❑ Safe receptacles for smoking materials should be provided, such as suitable
metal ashtrays and a separate metal garbage can with a fitted metal lid.
❑ Smoking areas should be provided with a suitable fire extinguisher.
❑ The risk of smoking materials being discarded around the perimeter of the
site should be considered and, if the risk is significant, precautions should
be implemented.
8.21 Standpipe Risers
❑ Standpipe risers with fire department connections should be installed
progressively as construction is undertaken, and unobstructed access
maintained.
❑ When a standpipe system is to be installed progressively in unoccupied
portions of a building under construction, a permanent or temporary
standpipe system is permitted. The standpipe system should have:
42
o Conspicuously marked and readily accessible fire department
connections on the outside of the building at street level;
o At least one hose outlet at each floor;
o Pipe size, hose valves and water supply conforming to local bylaws
and codes;
o At minimum, secure supports and restraints on alternate floors;
o At least one hose valve for attaching fire department hose at each
intermediate landing or floor level in the exit stairway; and
o Valves that are kept closed and protected from mechanical damage
at all times.
❑ A standpipe system introduced progressively should be installed so that it is
no more than one level below the highest forms, staging, and similar
combustible construction materials at all times.
❑ A temporary standpipe system should remain in service until the
installation of the permanent standpipe system is complete.
❑ If a building equipped with a standpipe system is being deconstructed or
demolished floor by floor, the system and all fire department connections
and valves should be maintained in operable condition at all times on all
storeys, except for the storey located immediately below the one being
deconstructed or demolished.
Please see Hose Stations and Hose Reels above for related information.
8.22 Temporary Buildings
❑ Temporary offices, sheds and construction shanties should be located
separately from other storage facilities having combustible construction or
contents.
❑ Temporary buildings should be located as far as possible away from the
building under construction or other occupied buildings — at least 10
metres, and 20 metres for combustible construction.
❑ A risk assessment should be conducted to determine fire precautions
within temporary buildings and accommodation, including temporary fixed
fire protection systems, portable firefighting equipment, and alarm systems.
❑ Temporary structures located inside any building should be of
noncombustible construction or protected by automatic sprinklers.
❑ Temporary structures that are located outside should be separated by a
minimum of 10 metres and not closely clustered.
❑ When floors of temporary buildings are raised above ground level, the
space beneath should be closed to prevent the accumulation of trash,
while still allowing for under -floor ventilation. No combustible materials
should be stored under the building.
❑ Temporary buildings where cooking takes place (including the use of
toasters) should have automatic fire detection installed.
❑ Temporary accommodation should not be provided in structures under
construction composed predominantly of combustible materials.
43
8.23 Waste
❑ Waste is both a fire and trip hazard and should be disposed of as soon as
possible. A clean floor policy creates a cleaner and safer environment.
❑ Dust and debris should be removed from the building and its immediate
vicinity at the end of each shift or as soon as possible.
❑ Scrap lumber and other combustible waste should be stored as far from
buildings as possible.
❑ Dumpsters should be located away from buildings (e.g. 15 metres) and far
enough from the perimeter to prevent deliberate ignition from outside the
boundary. If a dumpster must be located within the footprint of the
building, an on-site guard service should be assigned or hired to monitor it.
❑ Waste materials susceptible to spontaneous ignition, such as oily rags and
other materials contaminated by flammable liquids, should be stored in
clearly labeled noncombustible containers and removed from the site at
the end of each work shift.
❑ Waste or other material should not be permitted to fall freely from one
storey to another.
❑ Waste should be placed in a container that is designed to ensure the
deposited materials cannot escape, and that is secure and not accessible to
the public.
❑ Unless specific items of vegetation are to be retained, all dry/dead
vegetation should be removed from larger sites for a distance of 18 metres
from buildings and structures under construction.
❑ If waste chutes are used, whenever possible they should be constructed of
noncombustible materials and be located outside the building envelope.
❑ The accumulation of combustible materials close to waste chutes should be
minimized as far as possible. Dumpsters at the bottom of chutes need to be
changed out frequently to prevent chutes from becoming clogged with
debris.

Working with the Fire Department
9.1 Pre -fire or Pre -incident Plans
Pre -fire or pre -incident planning with the local fire department is a critical step, to
be taken before any substantial development of a construction site. Pre -incident
plans, which focus on information required for emergency responses, are
commonly required for construction projects in addition to fire safety plans.
NFPA 1620 Standard for Pre -Incident Planning is the common standard used for
these plans. Check with your local fire department to confirm the requirements in
your area.
A pre -incident plan typically includes information, site plans and drawings that
illustrate:
❑ Fire department access points to the site;
❑ Locations of fire extinguishers and initial attack equipment;
❑ Any special provisions for firefighting activities;
❑ The disposition of all built-in fire protection systems;
❑ Emergency escape routes and stairs;
❑ Available water supplies and positions of hydrants and hose reels that are
operative;
❑ Any other operative fire safety systems that have been provided;
❑ Locations of assembly points and registers of persons currently on the site;
and,
❑ Details of temporary accommodation and storage areas, including location
for storage of hazardous items such as flammable liquids and gas cylinders.
The fire department should also be made aware of any alternative solutions that
could affect firefighting operations, and any changes to the pre -incident plan that
may occur as construction progresses.
45
9.2 Notification Process
If an emergency occurs, it is essential that emergency responders are properly
notified and dispatched to the scene immediately. All people at a construction site
should be made aware that it is everyone's responsibility to take action if an
emergency occurs, including raising the alarm and contacting the fire department.
Procedures for notifying emergency responders should be well documented and
readily available to all employees and site visitors.
The training should include:
❑ What to do when you discover an emergency;
❑ How to raise the alarm and what should happen next;
❑ What should be done upon hearing a fire alarm sound;
❑ The procedures for alerting jobsite personnel and visitors, and directing
them to evacuate if needed;
❑ The specific arrangements and methods for notifying the fire department;
❑ The reporting of incidents, especially any near -misses; and,
❑ Policies and procedures to interface with responding units.
Documentation of a supervisor's investigation or report on each incident should
also be filed for all events.
9.3 Incident Command System
Fire departments use an Incident Command System (ICS) to manage their response.
An ICS provides a structured approach to all elements of a response — including
command structure, personnel, policies, procedures, facilities and equipment —
with the aim of improving the effectiveness of the response.
While aspects may vary for different departments, an ICS uses a "first -on -scene"
structure, in which the first responder to a scene becomes the Incident
Commander and remains in charge until one of the following occurs: the incident is
resolved, a more qualified responder arrives and receives command, or the
Incident Commander appoints his/her own replacement.
The person who reports an emergency at a construction site may have information
that will be valuable to the Incident Commander. Development of the site's fire
safety plan should include procedures on how to interact with the Incident
Commander to pass along information.
9.4 Water Supply
❑ A water -supply analysis should be conducted prior to the development of
the project to ensure adequate and reliable water supplies are available for
both firefighting operations and on-site fire protection systems.
❑ Water mains/connections that will feed hydrants, sprinklers and hoses
should be installed, tested and brought into service prior to the
introduction of any combustible elements to the site.
❑ If insufficient public hydrants are available, yard hydrants should be
installed.
❑ Public water supplies — including public hydrants, tested and verified —
should be in place before breaking ground. The same applies to yard
hydrants provided in lieu of public hydrants.
❑ When the site is remote and an adequate and reliable public water supply
is not available, an alternative means of providing the water supply should
be established, or means should be found to reduce the fire risk.
9.5 Fire Department Access
❑ Clear, marked and unobstructed fire department access to the site and
buildings should be provided at all times, and the fire department notified
immediately of any changes or restrictions to the access points.
❑ At fenced sites, provisions should be made to provide access to fire
department equipment and crews when required.
❑ Unobstructed access should also be maintained to fire hydrants, portable
extinguishers, and fire department connections for standpipe and sprinkler
systems.
❑ A means should be provided to allow firefighters to perform their duties on
all levels of the building. This includes making provision for the use of
elevators, hoists and lifts to assist firefighting crews to reach all levels of
the building.
❑ Significant changes to the access to the site should be discussed with the
fire department before being implemented.
Construction Zones within Occupied
Buildings
Renovation and maintenance activities are often undertaken after buildings have
received their certificate of occupancy and are occupied. This presents a number of
challenges to fire and life safety, and may also be subject to additional regulations.
Check the codes and bylaws for your area.
The principal contractor should take the lead in preparing a site fire safety plan, but
the construction crew employer and the building owner should be involved in
developing a plan that addresses all stages of the
construction/renovation/maintenance project.
Common issues to be addressed include:
❑ Isolation of existing fire protection systems in occupied areas and the
construction/renovation/maintenance zone;
❑ Verification of alarm system performance after adjustments and
reprogramming;
❑ Fire and smoke separation of the construction zone from occupied areas;
❑ Security to prevent unauthorized access to work areas;
❑ Blocking of evacuation paths from occupied parts of the building;
❑ Disturbance of service penetrations through existing fire separations;
❑ Modification of the performance of smoke management systems and
firefighting equipment;
❑ Monitoring of the construction/renovation/maintenance zone for fires; and
❑ Emergency notification for both the construction/renovation/maintenance
zone and occupied portion of the building.
A joint fire safety committee should be established to create, validate and
implement an emergency plan and procedures for the facility and construction
zones for the duration of the project. Responsibilities for the committee members
should be clearly defined.
