What is a Fire Watch and when might it be required?

• A. A backup fire extinguisher arrangement.
• B. A temporary alarm system used only for inspections.
• C. A plan to watch for weather hazards.
• D. A designated person who monitors for fire hazards and dangerous conditions when a required system is out of service or during hot work.

Answer: (D)

A Fire Watch is a designated person whose job is to observe for signs of fire and dangerous conditions while a required fire protection system is out of service or during activities that generate heat, such as hot work. This person stays on site to detect ignition sources (sparks, embers, overheating) and to take immediate action, like using an extinguisher or calling emergency services, to prevent a fire from starting or spreading. They should have access to fire extinguishing equipment, know the location of alarms and exits, and remain on duty for the duration of the hazardous activity and for a period afterward to ensure no smoldering continues.

This role is specifically linked to situations where a fire protection system isn’t operating or when hot work creates ignition risk, which is why it fits best. It’s not about a backup extinguisher setup in general, not about a temporary alarm system, and not about watching for weather hazards.
