Hot work permit
Before the work starts
OSHA 1910.252 asks the person who authorizes cutting and welding to inspect the area and set the precautions, preferably in a written permit. Construction work has its own rules in 29 CFR 1926 Subpart J. Check the current text and your own program.

- Combustibles moved at least 35 feet (10.7 m) from the work, or shielded with flameproof covers or guards
- Floor swept clean for 35 feet, and wet or covered if it is combustible
- Floor and wall openings, cracks and open doorways covered so sparks cannot drop or travel
- Ducts and conveyors that could carry sparks protected or shut down

- Used containers cleaned and vented before any heat is applied
