You arrive after a night of protests and find shattered glass near the lobby. The building is still standing, but the fire alarm panel shows multiple faults. A pull station has been torn from the wall. Water is running from a damaged sprinkler head. Your first instinct may be to board the opening, call the alarm company, and unlock the doors. That may not be enough.
A damaged fire alarm or sprinkler system can make an occupied building unsafe even after the street is quiet. The local fire marshal may require evacuation, closure, or an approved fire watch until repairs restore protection. A fire watch after protests gives trained personnel one narrow job: look continuously for signs of fire, report an emergency, warn occupants, and document every patrol. It is not a substitute for repairs. It can be the temporary control that lets a business remain open under conditions approved by the authority having jurisdiction.
Property managers should treat this as a fire protection impairment, not a cleanup problem. The decisions made during the first hour affect occupant safety, code compliance, and whether the doors can legally reopen.
Start with the life-safety systems, not the storefront
Broken windows and damaged merchandise are easy to see. Fire protection damage often hides behind the walls or inside a control panel. A severed communication line may stop alarm signals from reaching the supervising station. Impact to a sprinkler riser can close a control valve or reduce pressure. A damaged fire department connection may keep responding crews from supplying the system. Power loss can disable detection, notification appliances, smoke control equipment, or fire pumps.
Do not assume that a silent panel means the system is normal. Check the alarm display, sprinkler valves, pump status, fire department connections, emergency lighting, exit doors, and any area exposed to vandalism or water damage. Have licensed alarm and sprinkler contractors inspect their systems. Call the alarm monitoring company to confirm whether signals are reaching it. Record who checked each system, what was found, and when the impairment began.
Then notify the parties named in the building’s impairment plan. That list may include the fire department, alarm company, insurer, property owner, tenants, and facility leadership. The local fire marshal or other authority having jurisdiction, commonly called the AHJ, decides what temporary measures are acceptable. A national standard may inform that decision, but local adoption and amendments control enforcement.
Why a fire watch may let a business remain open
An operating alarm and suppression system detects fire, warns people, and controls growth. When part of that system is out of service, human patrols can cover some of the detection and notification gap. A guard walks the affected area on a fixed route, checks known hazards, keeps exits clear, and maintains a reliable way to call 911. If smoke, flame, unusual heat, or a burning odor appears, the guard acts without delay.
The AHJ can approve that temporary arrangement, impose conditions, or reject occupancy. Conditions may limit which floors remain open, reduce occupant load, stop hazardous work, require additional extinguishers, or set a patrol frequency. Some buildings may operate only during staffed hours. Others may need fire watch coverage around the clock, including closed hours when a delayed fire could spread unnoticed.
No provider can promise that hiring guards automatically prevents closure. The building official or fire marshal retains that authority. The useful question is whether your proposed fire watch addresses the actual impairment and can be deployed before the approved operating window begins.
The code framework behind the decision
The International Fire Code contains impairment provisions that direct the owner or responsible party to notify the fire department and follow approved procedures when required fire protection systems are out of service. Depending on the locally adopted edition and the AHJ’s direction, the response can include evacuation or an approved fire watch. Local amendments may add notification deadlines, guard qualifications, patrol intervals, or reporting forms.
NFPA 25 addresses inspection, testing, maintenance, and impairment of water-based fire protection systems. Its impairment procedures include planning the shutdown, identifying affected areas, notifying responsible parties, removing ignition sources where practical, and restoring the system promptly. The commonly cited sprinkler impairment threshold of more than 10 hours in a 24-hour period can lead to evacuation or an approved fire watch after notification to the AHJ. Do not apply that number blindly. Your adopted code, system type, occupancy, and local order can require action sooner.
Alarm impairments also need a controlled response. NFPA 72 provides a framework for managing fire alarm and signaling system impairments, including identifying the extent of the outage and notifying affected parties. A panel may appear partly operational while an entire initiating-device circuit, notification zone, or supervising connection is unavailable. The impairment must be defined before anyone can design an effective patrol.
If repairs involve cutting, welding, brazing, torch-applied roofing, or other hot work, NFPA 51B becomes relevant. Hot work introduces ignition sources at the same time the building has reduced protection. The permit authorizing individual should evaluate the area, remove or shield combustibles, confirm extinguisher access, and assign a separate hot work fire watch when required. A building impairment patrol does not automatically satisfy the duties or duration of a hot work watch.
What trained fire watch guards do on site
A guard needs a written post order tied to the building and impairment. Generic instructions such as “walk the property” are not enough. The order should identify the affected floors, rooms, risers, alarm zones, hazards, patrol frequency, communication method, emergency contacts, and evacuation procedure. It should also state who can end the watch.
Before the first round, the guard should receive a site briefing. That briefing covers exits, stairwells, assembly areas, extinguisher locations, fire department access, utility shutoffs, construction zones, vacant suites, and areas where protest damage occurred. The guard should know which devices are out of service and which protections remain active.
During each patrol, the guard looks for smoke, flame, sparks, unusual heat, burning odors, leaking fuel, damaged electrical equipment, obstructed exits, and unsafe storage. The guard checks that fire doors are not blocked and that access lanes remain available to responding crews. In buildings open to the public, the route must account for loading docks, trash rooms, kitchens, mechanical spaces, sales floors, parking structures, and any boarded area where visibility has changed.
Every round belongs in a fire watch log. A useful entry records the date, start time, guard’s name, exact areas checked, conditions observed, corrective action, and completion time. Logs should be written as the patrol occurs, not reconstructed at the end of a shift. The property representative should retain them for the AHJ and the insurer.
If the guard finds a fire, the sequence is direct: call 911, initiate the approved occupant warning or evacuation procedure, notify site management, and use an extinguisher only if the fire is incipient, the guard is trained, and a safe exit remains behind the guard. A fire watch post is not interior structural firefighting.
Fire watch and security are different assignments
After civil unrest, a property may need security officers for access control, vandalism prevention, and conflict response. It may also need fire watch guards because alarm or sprinkler protection is impaired. Those jobs overlap geographically, but their priorities differ.
A security officer watching an entrance cannot leave that position for timed patrols through a large building. A fire watch guard should not be pulled away to manage a crowd, protect merchandise, or escort contractors if that interruption breaks the approved patrol schedule. Combining the roles without AHJ approval creates gaps and weakens the log.
Use separate staffing when both risks are active. Give each team clear radio channels, supervisors, escalation procedures, and boundaries. Fire watch should remain focused on fire detection, notification, evacuation support, and records.
Match staffing to the building and the damage
A single guard may cover a small, empty retail suite with one affected zone. That same person cannot reliably patrol a high-rise, hospital, warehouse, or multi-building campus at the same interval. Route timing should be tested by walking it. If one complete round takes longer than the required interval, divide the property into zones and add guards.
Occupancy changes the plan. A hotel operates while guests sleep and may need coverage on every occupied floor. An assisted living facility has residents who need help evacuating. A warehouse may contain high-piled storage that hides early smoke and accelerates fire spread. A restaurant adds cooking hazards, grease ducts, and compressed gas. A construction site has open shafts, temporary wiring, changing egress routes, and hot work.
Protest damage can also create special hazards. Boarded windows may reduce visibility and alter exits. Water from a broken sprinkler line can reach energized equipment. Debris can block fire lanes. Accelerants or discarded fireworks may remain near the exterior. Contractors making emergency repairs can introduce temporary heaters, generators, extension cords, and hot work. Add those conditions to the patrol order instead of relying on a standard checklist.
A practical reopening decision
Before opening, answer five questions in writing. What exact fire protection functions are impaired? Which areas and occupants are exposed? What has the AHJ authorized? Can guards complete the required route and keep accurate logs? Who is responsible for repairs and system restoration?
If any answer is unclear, keep the decision with the property representative and AHJ. Do not let the pressure to reopen turn an unknown impairment into an assumed one. A documented call with the fire marshal is more useful than a verbal message passed through several contractors.
Once the plan is approved, brief tenants and employees. Tell them which system is impaired, how they will receive an emergency warning, which exits to use, and who has authority on site. Post emergency numbers where guards can reach them. Keep keys, floor plans, system drawings, permits, and impairment tags available. Confirm that portable extinguishers are accessible and current.
Management should review logs during every shift. Missed rounds, repeated access problems, or new hazards require immediate correction. If the building changes use, opens another floor, starts hot work, or loses another part of the system, contact the AHJ and revise the plan.
End the watch only after formal restoration
A contractor saying “the repair is done” does not always end the impairment. The alarm or sprinkler system must be returned to service, required testing must be completed, valves and controls must be placed in normal position, and the supervising station must receive the proper signals. The impairment coordinator should confirm restoration with the responsible contractor and follow the AHJ’s release process.
Notify everyone who received the original impairment notice. Remove temporary tags only when authorized. Collect fire watch logs, contractor reports, test records, and the written release in the property file. If some zones remain disabled, update the affected area and continue coverage there.
