Construction sites in British Columbia are among the highest fire-risk environments in the province. Exposed wood framing, temporary electrical systems, cutting and welding operations, and the absence of completed fire suppression infrastructure create conditions where a single ignition event can destroy months of work and put workers’ lives at risk.
BC law does not leave fire safety on construction sites to chance. The BC Fire Code, WorkSafe BC regulations, and local municipal bylaws all place specific obligations on general contractors and site supervisors and fire watch security guards are a central part of meeting those obligations. This guide covers exactly when fire watch is required, what qualified fire watch coverage looks like, and what happens when a site does not have it.
What Is a Fire Watch and Why Construction Sites Need One
A fire watch is a dedicated, continuous monitoring function carried out by qualified personnel, most commonly licensed fire watch security guards, whose sole responsibility during their deployment is to detect signs of fire, ensure fire suppression equipment is in place and accessible, and raise the alarm or initiate response before a fire spreads.
On a completed building, fire alarms, sprinkler systems, and monitored suppression infrastructure do much of this work automatically. Construction sites are different. Sprinkler systems are often not yet installed or are temporarily out of service. Fire alarm systems may not be operational. Workers carrying out hot work welding, cutting, grinding, torch operations are introducing ignition sources into environments where combustible materials are everywhere and automatic suppression does not exist yet.
Fire watch security guards fill that gap. They are the human layer of protection that substitutes for the systems that are not yet in place, and they remain on site until those systems are restored or the conditions that triggered the requirement have passed.
When Does BC Law Require Fire Watch on a Construction Site?
There are three primary regulatory frameworks that govern fire watch requirements on BC construction sites. All three can apply simultaneously.
BC Fire Code 2024 Section 5.6
The BC Fire Code 2024, which came into effect March 8, 2024 and is based on the National Fire Code 2020, governs fire safety during construction and demolition under Section 5.6. Fire watch is specifically required when fire protection systems are temporarily impaired for example, when sprinklers are offline for testing, installation, or modification. Municipal fire departments across BC enforce these requirements, and after several high-profile construction fires in Metro Vancouver, enforcement has tightened significantly. General contractors are now regularly asked to produce Fire Safety Plans before permits are issued and during routine site inspections.
WorkSafe BC Section 8.30 (Hot Work)
WorkSafe BC Occupational Health and Safety Regulation Section 8.30 requires continuous fire watch monitoring during all hot work activities and for a minimum of 60 minutes after hot work is completed. Hot work includes welding, cutting, grinding, brazing, soldering, torch operations, and any other activity that produces sparks, flame, or heat capable of igniting surrounding materials.
A written hot work permit is mandatory before any hot work begins on a BC construction site. The permit must identify the fire watch personnel assigned, specify the safety equipment in place, and document emergency response procedures. WorkSafe BC-qualified fire watch personnel must be on site for the duration and for the full 60-minute post-work monitoring period without exception.
Wood-Frame Construction 24/7 Fire Watch Requirement
Once wood-frame construction commences on a BC project, many municipalities including New Westminster and Vancouver require fire watch to be implemented 24 hours per day, 7 days per week. This requirement typically remains in effect until the fire protection systems for the building are fully operational. The New Westminster Fire and Rescue Services Construction Fire Safety Bulletin makes this explicit: fire watch must be conducted by qualified personnel and cannot be delegated to general construction workers as a secondary task.
What Qualified Fire Watch Security Guards Are Required to Do
A fire watch is not simply having someone on site. Regulatory authorities having jurisdiction (AHJs) typically the local fire department expect specific, documented conduct from fire watch personnel. A properly qualified fire watch security guard on a BC construction site is required to:
- Maintain continuous, uninterrupted observation of the designated fire watch area no other tasks during a fire watch assignment
- Carry appropriate fire extinguishing equipment and know how to operate it across multiple fire classifications
- Conduct patrol checks of all active work areas, stairways, hoisting areas, and combustible storage zones
- Maintain a detailed written log of every patrol recording time, route, observations, and any anomalies
- Follow documented emergency communication protocols, including who to contact, in what order, and how to notify adjacent property representatives if required
- Remain on site for the full 60-minute post-hot-work monitoring period without departure
In British Columbia, fire watch personnel who perform security functions must also hold a valid security worker licence issued by the Ministry of Public Safety and Solicitor General. This means your fire watch provider must meet both the fire safety training requirements and the provincial security licensing requirements, not one or the other.
What the Documentation Must Include
Compliance documentation is not optional. The BC Safety Authority conducts regular site inspections, and violations can result in immediate work stoppages. Proper fire watch records that your provider should be producing include:
- Dated patrol logs for every shift, noting times, routes completed, and observations
- Copies of all written hot work permits with fire watch personnel identified by name and licence number
- Equipment inspection records confirming extinguishers were checked and serviceable at the start of each shift
- Incident reports for any anomaly even minor ones that occurred during the watch period
These records serve two purposes: they demonstrate regulatory compliance during inspections, and they protect the general contractor and site owner in the event of an insurance claim or liability dispute after an incident.
The Real Risk of Getting This Wrong
Construction fires in BC have become more frequent and more damaging. The province updated the BC Fire Code in 2024 specifically to address gaps that contributed to losses on wood-frame and mid-rise projects. A fire on an unprotected site does not just destroy the structure it can injure or kill workers, trigger regulatory investigations, void insurance coverage, and result in personal liability for the general contractor and site supervisor.
Hiring unqualified personnel for fire watch general labourers asked to watch for fire as a secondary duty, or workers without valid security licences carrying out fire watch functions does not satisfy BC’s regulatory requirements and will not be accepted by an AHJ or an insurer reviewing a claim. The financial exposure from a single non-compliant fire watch decision is many times the cost of doing it properly.
Why BC Construction Sites Trust Imperial Security Group for Fire Watch
Imperial Security Group has provided licensed security guard services to construction, commercial, and institutional sites across British Columbia and Alberta since 1993. Every Imperial fire watch security guard holds a valid BC security worker licence and is trained specifically for construction site fire watch deployment including hot work monitoring, wood-frame building coverage, and impaired-system fire watch protocols.
Imperial’s fire watch services are available for short-term hot work coverage, extended wood-frame construction deployments, and emergency impaired-system callouts across Vancouver, Victoria, Nanaimo, Burnaby, Surrey, Langley, Kelowna, Abbotsford, Chilliwack, and throughout Western Canada. Patrol reports are produced after every shift, documentation is maintained for the life of the project, and clients have a direct point of contact not a call centre for scheduling, changes, and urgent coverage requests.
For construction projects in BC requiring fire watch security guards that meet WorkSafe BC, BC Fire Code, and municipal requirements, contact Imperial Security Group for a site assessment and coverage quote.
Final Thought
Fire watch on a BC construction site is not a box to check; it is a specific legal obligation with precise documentation, personnel qualification, and coverage duration requirements attached to it. The general contractors and site supervisors who handle it correctly are the ones who have qualified, licensed fire watch security guards on site before hot work begins, maintaining logs throughout every shift, and staying the full 60 minutes after the last spark. The ones who treat it as an afterthought tend to find out the cost of that decision the hard way.
Frequently Asked Questions
- How long must fire watch be maintained after hot work ends on a BC site?
WorkSafe BC Section 8.30 requires a minimum of 60 minutes of continuous fire watch after hot work is completed. The fire watch guard must remain on site and actively monitoring for the full duration no exceptions.
- Do fire watch guards in BC need a security licence?
Yes. In BC, personnel performing fire watch who also carry out security functions must hold a valid security worker licence issued by the Ministry of Public Safety and Solicitor General. A company providing only fire training without provincial security licensing does not meet the full legal standard.
- When does 24/7 fire watch become mandatory on a construction site?
Once wood-frame construction begins, many BC municipalities require fire watch 24 hours a day, 7 days a week, until the building’s permanent fire protection systems are fully operational.
- What happens if a BC construction site fails a fire watch inspection?
The BC Safety Authority can issue an immediate work stoppage order. Beyond regulatory penalties, a non-compliant fire watch can void insurance coverage in the event of a fire and expose the general contractor and site supervisor to personal liability.
