Your sprinkler contractor closes the control valve at 10:40 p.m. A tenant event is still underway upstairs. The alarm company says the panel will show a supervisory signal until repairs finish. Who do you call when a fire watch is needed?
Start with the contacts named in your impairment plan. Notify the building owner or impairment coordinator, the alarm monitoring company, and the local fire code official or fire department as your adopted code and permit conditions require. If the authority having jurisdiction allows the building to remain occupied, call a professional fire watch company that can put trained guards on the property and document every patrol.
If you see smoke, flame, or another immediate threat, call 911. Pull the alarm and evacuate according to the building plan if you can do so safely. A fire watch is not an emergency response crew, and it does not make an active fire safe.
Make the emergency call before the fire watch call
The first decision is simple: Is there a fire or only a loss of protection?
Smoke, visible flame, unusual heat, an explosion, or the smell of burning material points to an active emergency. Call 911. Do not ask a maintenance employee or security officer to investigate alone. Begin the evacuation procedure and meet firefighters with keys, access information, and the location of the reported hazard.
A fire watch covers a different condition. The building has no active fire, but one or more safeguards are out of service or a temporary operation has raised the ignition risk. Examples include a disabled sprinkler zone, failed fire pump, empty water supply, alarm panel outage, damaged standpipe, blocked notification circuit, or hot work near combustible material.
That difference matters. Calling a guard company first should never delay a 911 call. Once you confirm there is no active fire, move into the impairment process.
The authority having jurisdiction, often called the AHJ, decides what the adopted fire code requires at your property. Depending on the location, that may be the municipal fire marshal, a fire prevention bureau, a county official, a state agency, or another code official.
Many jurisdictions base their rules on a version of the International Fire Code. The model IFC provisions for an out-of-service fire protection system generally call for notice to the fire department and the AHJ. They may require evacuation or an approved fire watch until the system returns to service. The exact language, time threshold, reporting method, and staffing conditions depend on the edition and local amendments.
Do not wait for an assumed national time limit. Some owners have heard that every outage receives the same four-hour or ten-hour grace period. That is not a safe operating rule. Your occupancy, impaired equipment, permit conditions, and local adoption control the response.
Tell the official what failed, which areas lost protection, when the outage began, whether the building is occupied, and when repairs are expected. Ask four direct questions:
- May the affected area remain occupied?
- Is a fire watch required now?
- What patrol frequency and log format will be accepted?
- Who must receive notice when the system is restored?
Record the official’s name, agency, call time, and instructions. If the office uses an online impairment form or email address, send the required notice and keep the confirmation.
Activate the building impairment plan
NFPA 25 addresses inspection, testing, and maintenance of water-based fire protection systems. Its impairment procedures assign responsibility for controlling an outage, identifying its extent, notifying affected parties, and restoring protection. Your locally adopted edition may use different section numbers, so follow the approved site plan and the AHJ’s direction rather than a checklist copied from another property.
The owner or designated impairment coordinator should take control. Confirm which valves, zones, floors, and devices are affected. Tag impaired equipment. Stop hazardous operations in the unprotected area. Notify the alarm monitoring company so responders are not working from incomplete information. Contact the sprinkler, alarm, pump, or suppression contractor needed for repair.
Notify people inside the building as the plan requires. That list can include management, security, tenants, supervisors, the insurance contact, and anyone responsible for an assisted evacuation. A hospital, hotel, apartment tower, warehouse, and construction site do not have the same exposure. The response should match the people and fuel load inside the affected space.
If the AHJ orders evacuation, a fire watch does not overrule that order. Close or clear the area. Post the required out-of-service signs. A professional provider can still protect an empty site during repair, but occupancy resumes only when the official permits it.
Call a qualified fire watch provider with usable details
Once the AHJ permits a watch, call a provider that handles emergency deployment rather than a general guard desk with no fire watch procedure. The dispatcher needs facts, not a request to “send somebody.”
Have the property address and the correct entrance ready. Give the building type, occupied floors, expected head count, impaired system, affected area, outage start time, repair estimate, and AHJ instructions. Identify access restrictions, parking limits, required personal protective equipment, and the person who will meet the guard. Say whether one post covers the approved route or whether the official ordered several posts.
Ask how the provider trains guards to recognize hazards, raise an alarm, contact emergency services, patrol assigned areas, and maintain a fire watch log. Confirm the estimated arrival, minimum shift, relief procedure, supervisor contact, and proof of insurance. If your jurisdiction requires a specific license or guard credential, say so before dispatch.
A nationwide company should still work from local instructions. The provider can supply trained personnel and operating discipline. Only the AHJ can approve the watch for that particular outage.
Match staffing to the actual building
One guard cannot be everywhere at once. A short route around a single retail suite is different from a high-rise with locked stairs, a sprawling warehouse, or an active construction project.
In a hotel or apartment building, the route may include sleeping floors, stairs, mechanical rooms, trash rooms, and common corridors. Guards need a reliable way to report a fire and must account for residents who may need help evacuating. Management should keep exits open and give the watch current access keys.
In a hospital or care facility, defend-in-place procedures, smoke compartments, medical gas, and patients with limited mobility change the plan. Facility leadership and the life-safety team should set routes with the AHJ. A guard should not improvise patient movement.
Warehouses add long travel distances, tall storage, charging stations, loading activity, and concealed spaces. A route that takes longer than the required patrol interval needs another guard or a smaller patrol zone. At construction sites, open shafts, temporary heat, incomplete stairs, changing access, and combustible debris demand daily route review.
Ask the guard to walk the route with the site contact at shift start. Time it. If the route cannot be completed at the interval ordered by the AHJ, adjust the staffing before the first cycle is missed.
Use a separate plan for hot work
Welding, cutting, brazing, grinding, and torch-applied roofing can throw sparks or transfer heat beyond the immediate work area. NFPA 51B covers fire prevention during welding, cutting, and other hot work. The permit authorizing individual should review the area, approve controls, and decide whether a fire watch is required under the adopted program.
The hot-work fire watch stays focused on ignition sources, nearby combustibles, floor and wall openings, and areas where sparks can travel. The watcher needs suitable extinguishing equipment and a clear method to stop work and raise the alarm. The watch continues through the post-work period required by the permit, adopted standard, and site conditions.
Do not combine incompatible duties. A worker who is welding cannot act as the watcher. A guard assigned to patrol an entire impaired building may not be able to continuously observe a hot-work area. Treat those as separate posts unless the AHJ and permit plan specifically approve the arrangement.
Know what the guard should do on arrival
A fire watch guard should receive a written post order, site orientation, emergency numbers, an approved patrol route, and instructions from the owner or impairment coordinator. The guard checks exits and fire lanes, watches for smoke and unsafe heat, notes new hazards, keeps combustible material away from ignition sources, and confirms that required portable extinguishers remain accessible.
The log should show the property, affected system, guard name, shift time, patrol start and finish times, areas checked, observations, corrections, and notifications. Entries need to be made as the patrol occurs. A log completed from memory at the end of the shift has little value to the next guard or the fire marshal.
If the guard finds smoke or fire, the response should already be clear: call 911, activate the alarm or use the approved notification method, start evacuation procedures, and report the exact location. Portable extinguisher use is limited to a small incipient fire when the guard is trained, has a safe escape route, and site rules allow it. Chasing a growing fire is not the job.
The guard should also report conditions that make the route unsafe or incomplete. A locked stair door, blocked aisle, failed radio, or expanding work zone can defeat the plan even when patrol entries look timely.
Control the first hour from one checklist
Property managers can keep the response moving with a short written sequence:
- Call 911 and evacuate if there is an active fire or immediate life hazard.
- Identify the impaired equipment, area, and outage start time.
- Notify the impairment coordinator, alarm monitoring company, service contractor, and AHJ as required.
- Follow the AHJ’s decision on evacuation, occupancy, patrol intervals, and staffing.
- Stop hazardous work and remove avoidable ignition sources from the affected area.
- Call a qualified fire watch provider and give the complete dispatch details.
- Brief the arriving guard, walk the route, test communications, and start the log.
- Keep repair updates and AHJ instructions with the impairment record.
Save these contacts before an outage. Put the fire prevention office, alarm company, sprinkler contractor, building engineer, property lead, and emergency fire watch provider in the plan. At 2 a.m., a tested contact list is more useful than a binder nobody can find.
End the watch only after restoration is confirmed
A repair technician finishing work does not automatically end the watch. The responsible contractor must return the system to service and complete the required testing. The impairment coordinator should verify that valves are open, alarms and supervisory devices are normal, tags are removed when authorized, monitoring is active, and affected parties receive restoration notice.
Ask the AHJ whether approval or a final notice is required before guards leave. Keep the patrol logs, contractor record, monitoring confirmation, and official communications together. If the system cannot be fully restored, document the remaining impairment and continue the approved controls.
The answer to who you call is a sequence, not one phone number. Call 911 for an emergency. Call the AHJ for the occupancy and fire watch decision. Call the building team and system contractor to control and repair the impairment. Then call a trained provider to carry out the approved watch.
