Question: After completing a hot work operation, the fire watch personnel usually remain on duty for a minimum duration to ensure no smouldering fires ignite. What is the generally recommended minimum duration for a fire watch after hot work cessation?
Answer options: ✅ 30 minutes.
- 5 minutes.
- Immediately after the welder stops.
- Until the area has completely cooled to the touch.
Correct answer: 30 minutes.
Explanation: Industry best practice and safety regulations, such as those often referenced by provincial WHSCC boards and NFPA, typically require a fire watch to remain for at least 30 minutes after hot work is completed to detect and extinguish any delayed-ignition fires. Immediately stopping or shorter durations may not be sufficient for smouldering materials to flare up.
