Coverage When Your Fire Systems Can’t Be
A fire watch is a trained person whose only job is to patrol your property, watch for fire hazards, and sound the alarm and call 911 if anything happens — required whenever your built-in fire protection is impaired. Under NFPA standards and local Texas fire codes, a fire watch is typically required when a sprinkler or alarm system is out of service, during and after hot work like welding or cutting, and when ordered by the fire marshal for an impairment or event.
Op6 fire watch officers conduct continuous patrols on the schedule your authority having jurisdiction (AHJ) or insurer requires, maintain a detailed written log of every round, and respond immediately to any sign of fire — keeping your people safe and your operation in compliance until your systems are restored.

Learn MoreWhat Drives Your Fire Watch Cost
Fire watch cost is driven almost entirely by one thing: what the fire marshal or your insurer requires, and for how long. Once that’s on paper, the scope is straightforward.
- Required round interval. A 15-minute round and a 60-minute round are different staffing problems. On a large footprint, a short interval can require more than one officer just to complete a round on time.
- Size and layout. Square footage, number of buildings, floors, stairwells, roof access, and how much ground a single round actually covers.
- Length of the impairment. A two-day sprinkler repair, hot work across one shift, or a multi-week system outage. A longer scheduled watch is easier to staff efficiently than a short emergency block.
- Coverage pattern. Some watches are ordered around the clock; others run only overnight or only while the building is occupied.
- Overnight, weekend, and holiday hours. These are the hardest hours to staff, and fire system failures rarely wait for a Tuesday morning.
- Documentation requirements. Timestamped rounds, photo verification, and impairment logs formatted for the fire marshal and your insurance carrier.
- Occupancy and risk. Hot work on an active construction site, high-occupancy buildings, and hazardous storage all raise the risk profile of the watch.
- Short-notice mobilization. A same-day emergency start pulls officers off an existing rotation, so it is scoped differently than a watch you schedule in advance.
