Who Can Perform a Fire Watch?
Your fire alarm contractor removes the panel for a planned four-hour repair. Six hours later, the panel is still dark. Tenants are in the building. The night security officer asks whether he is now the fire watch.
That is the wrong time to decide who can perform a fire watch. A name on the schedule is not enough. The person must be trained, equipped, free from competing duties, and accepted by the authority having jurisdiction (AHJ). If those pieces are missing, the building may still have an unprotected life-safety gap even though someone is walking the halls.
The practical answer is that an employee, security officer, maintenance worker, or contracted guard may be allowed to perform the watch. Local code, the fire marshal’s order, and the conditions at the property control the final decision. The job cannot be handed to whoever happens to be available.
A fire watch is a life-safety assignment
A working sprinkler or alarm system watches the building every second. When part of that protection is impaired, a human patrol may be ordered as a temporary safeguard. That person looks for smoke, fire, unusual heat, and unsafe work. The guard also checks exits and access routes, reports dangerous conditions, keeps timed records, and starts the emergency notification process without delay.
This is active work. It is not a person sitting at the front desk waiting for somebody else to report smoke. It is not a maintenance technician glancing down a hallway between repair tasks. The patrol has to cover every affected area on the interval ordered by the AHJ, including mechanical rooms, stairwells, storage spaces, concealed-risk areas that can be observed safely, and exterior sections included in the plan.
The assigned person must know the building well enough to move through that route without missing locked, remote, or easy-to-forget spaces. In a large property, one guard may not be able to finish the route within the required interval. The plan then needs more people or separate patrol zones.
What the IFC and NFPA 25 require
The International Fire Code gives the fire code official authority to order a fire watch when a required fire protection system is out of service or another hazardous condition creates an unacceptable risk. The IFC also permits other approved actions in some situations. The fire official decides what is acceptable for that building and that incident.
NFPA 25 addresses the inspection, testing, maintenance, and impairment of water-based fire protection systems. Its impairment process places responsibility on the property owner or designated impairment coordinator. That process includes identifying the affected system, notifying the required parties, controlling hazards, arranging temporary protection when required, and restoring the system properly. A patrol does not replace the repair. It covers a limited period while the impairment is managed.
There is no single nationwide time trigger that applies to every property. States and cities adopt different editions of the IFC and NFPA standards, then add local amendments. A fire marshal can also issue an order based on the occupancy, the portion of the system affected, the expected repair time, and the hazards inside. Hospitals, hotels, apartment buildings, warehouses, schools, and active construction sites do not present the same risk.
Do not wait for a remembered threshold from another city. Report the impairment through the required local process and ask the AHJ whether a watch is required, when it must begin, what areas it must cover, and how often rounds must be completed. Get those instructions in writing when possible.
Who can perform a fire watch?
Most codes do not name one universal license called a fire watch certification. They focus on whether the assigned person can perform the required duties. Some states or cities regulate the work as a security service, require a guard license, or place added rules on contracted providers. Some fire departments require a specific form, briefing, or approval before the first round.
An in-house employee may be acceptable if that employee has documented training and no other job during the watch. A security officer may qualify if the fire watch replaces the officer’s usual post rather than being piled on top of normal rounds, access control, parking enforcement, and incident calls. A maintenance employee may qualify only after stepping away from the repair and every other maintenance assignment. The person working on the disabled system should not be expected to repair it and patrol the building at the same time.
A professional fire watch guard is often the cleaner choice for an occupied building, a long outage, an overnight assignment, or a property with several patrol zones. The provider can supply relief staff, supervisors, training records, route logs, and guards dedicated to the post. That does not remove the owner’s responsibility. Property management still has to give the guard access, disclose hazards, provide site information, and coordinate with the AHJ.
Job title alone proves nothing. A licensed security guard who has not been briefed on the impairment, alarm method, route, or extinguisher locations is not ready. A veteran maintenance worker with no relief coverage is not ready either. The assignment follows demonstrated ability, not seniority.
The qualifications that matter on the first round
A qualified fire watch guard must understand exactly what protection is unavailable. A sprinkler valve closed for repair creates a different problem from a silent alarm panel or a disabled standpipe. The guard needs a plain-language briefing that identifies the affected floors, rooms, zones, devices, and expected restoration time.
The guard must be physically able to complete the patrol. That can mean repeated stairs, long corridors, outdoor yards, construction floors, or industrial areas. The route and interval must be realistic. If one complete round takes longer than the ordered patrol interval, the staffing plan has already failed.
The guard must recognize early signs of fire and common ignition hazards. Smoke odor, hot surfaces, damaged electrical equipment, blocked exits, accumulating waste, open-flame work, and combustible storage near heat sources all require attention. The guard also needs training on the portable extinguishers available at the property. An extinguisher is for a small, controllable fire with a safe exit behind the user. The guard’s first duty is notification and occupant safety, not an interior firefighting attack.
Communication has to work even if the impaired system normally provides the alarm. The guard needs a charged phone or radio, the correct emergency contact method, and instructions for warning occupants. Dead zones should be found before the first patrol. A written call sheet should include 911, the property contact, the alarm or sprinkler contractor, and any fire department number supplied by the AHJ.
Every round needs a record. A useful fire watch log identifies the property, date, guard, patrol area, start and finish time, conditions found, corrective action, and handoff between shifts. Entries should be made as the work happens. A page filled in at the end of the night is not a reliable record. Review our fire watch checklist for system impairments before the outage begins.
When an employee should not take the post
Do not assign the watch to a person who must answer phones, receive deliveries, monitor a lobby, perform repairs, clean rooms, or respond to unrelated security calls. Competing duties create missed rounds. The watch must be the person’s primary assignment for the full shift.
Do not use anyone who has not been briefed on the route and notification procedure. Do not use a person who cannot enter every required patrol area. Keys, badges, escorts, fall protection, or site-specific safety training may be needed before the post starts. A guard stopped by a locked mechanical room cannot complete the watch.
Fatigue also matters. Fire watch work is repetitive, and overnight rounds can stretch across several shifts. Schedule relief before the original guard reaches the point where attention drops. The handoff should happen face to face, with the outgoing guard explaining the impairment status, open hazards, log location, and last completed round.
Property managers sometimes ask a tenant, resident, or volunteer to “keep an eye out.” That is not a planned fire watch. Unless the person is formally assigned, trained, equipped, documented, and approved where approval is required, the property should not count that arrangement as code compliance.
Hot work uses a separate fire watch test
Welding, cutting, brazing, and other spark- or flame-producing jobs bring their own rules. Under OSHA’s general-industry welding and cutting standard, fire watchers are required when more than a minor fire could develop. Examples include appreciable combustible material within 35 feet, combustible material located more than 35 feet away but easily ignited by sparks, wall or floor openings that expose hidden spaces, and metal partitions that can carry heat to combustibles on the far side.
The hot work watcher must have suitable fire extinguishing equipment ready and be trained to use it. The watcher must know how to sound the alarm. OSHA requires the watch during the work and for at least 30 minutes after welding or cutting ends so a smoldering fire is not left behind. The permit issuer, facility policy, adopted NFPA 51B provisions, or local fire official may require a longer period.
A hot work fire watch should not help with the welding while also watching for sparks. The watcher needs a clear view of the work area and any exposed opposite side of a wall, floor, or partition. If one person cannot see every hazard area, add another watcher. Stop the work if conditions move outside the permit or if the watcher has to leave.
How to approve a person before the impairment
Start with the AHJ. Describe the occupancy, system affected, portion of the building without protection, expected outage, and repair plan. Ask whether the department requires a fire watch, a permit, a specific patrol interval, or direct notification when the watch begins and ends.
Next, walk the proposed route with the person who will stand the post. Mark every required room and floor. Check keys, lighting, stair access, communication coverage, extinguisher locations, and the method used to alert occupants. Time the route at a safe walking pace. Add staff if the round cannot be completed on schedule.
Then review the guard’s training records and the written duties. The briefing should cover the impaired equipment, patrol interval, hazards, alarm sequence, evacuation actions, extinguisher limits, log entries, escalation contacts, and shift relief. Our article on fire watch guard training and certifications explains what to ask a provider to document.
Finally, plan the stand-down. The watch does not end because a contractor says the repair is nearly done. The system must be restored, tested, and returned to service through the required process. Notify the parties identified in the impairment plan. Keep the completed logs with the work order and system records.
Use a dedicated guard when the risk is real
If your only available employee also has another post, does not have documented training, cannot cover the route on time, or lacks relief, call a qualified provider. That decision is cheaper than explaining an empty log after a fire or a missed round during a marshal inspection.
