Torch work is planned beside combustible framing and concealed cavities. What controls are needed?
- AWet only the visible pipe
- Apply hot-work and fire-watch controls
- CUse oxygen to ventilate the space
- DLeave immediately when the flame is off
Why B is correct
Torch heat and sparks can ignite hidden material after work ends. Removal or shielding of combustibles, permits, fire watch, extinguishers, ventilation, and post-work monitoring control that delayed-fire risk.
