Fire Watch

In Plain English

A dedicated worker who monitors an area for fire during and after welding or other hot work.

Definition

A fire watch is a designated worker stationed to observe an area for fire during and after hot work operations such as welding, cutting, or grinding. OSHA requires a fire watch when hot work is performed near combustibles, when walls or floor openings expose combustibles, and for 30 to 60 minutes after hot work is complete. The fire watch must be equipped with fire extinguishers and trained in their use.

Example

The welding inspector required a 30-minute fire watch after all pipe welding on the roof because combustible roofing materials were within 35 feet.
