When a sprinkler system, fire alarm, or standpipe goes out of service — whether for repair, renovation, or an unplanned outage — most local fire codes require continuous fire watch coverage until the system is restored. Getting this wrong isn't just a compliance issue; it's the kind of gap that shows up in an insurance claim.
What a fire watch officer actually does
A fire watch isn't a security guard standing near an exit. The role includes scheduled patrols of the affected area (typically every 30 minutes, though local codes vary), a written log of each patrol with timestamps, immediate notification procedures if a hazard is spotted, and familiarity with the building's evacuation plan and manual alarm locations.
When you need one
Common triggers include a sprinkler or standpipe system taken out of service for maintenance, a fire alarm system malfunction or impairment, hot work (welding, cutting) in areas without active suppression, and construction phases where permanent systems aren't yet operational.
Documentation is the part people skip
Most jurisdictions require a fire watch log that can be produced on request — not just "we had someone there." If your current provider can't hand you a timestamped patrol log at the end of a shift, you don't actually have a compliant fire watch; you have a person standing in a hallway.
How long does it need to last?
Until the impaired system is fully restored and verified, full stop. This is where a lot of properties get caught off guard: a repair that was supposed to take an afternoon turns into a multi-day parts delay, and fire watch coverage needs to scale with it, not lapse because the original estimate was optimistic.
