In Fire/Smoke Dampers, Access Doors & Rated Assemblies, I’m looking at: What do I do when covering UL label or losing documentation? What should I verify before I cut, drill, seal, cover, move, or install?

Do not

Do not treat damper or rated-assembly work like normal duct. Do not paint over, cover, remove, or lose damper labels/documentation.
