What should go into a hot work permit?

NFPA 51B and 29 CFR 1910.252 expect each permit to outline scope, duration, hazards, atmospheric testing, fire watch assignments, and post-work inspections. For restaurants and fabrication shops we also add GHS references for cleaning solvents, near-miss reporting instructions, and photos of temporary shielding. Capture LOTO status and ventilation checks so investigators see how you prevented flashback. Keep permits for at least 12 months with signatures from supervisors plus the designated fire watch so OSHA can confirm you trained the role.
