Field checklist

Confirm the damper type and exact location.
Find the access side, label, actuator, fusible link, sleeve, blade area, or inspection point.
Check that permanent access remains reachable after walls, ceiling, insulation, hangers, and other trades are installed.
Verify the access door size/location and confirm the panel can actually be opened and used after finish work.

Ask foreman

In Fire/Smoke Dampers, Access Doors & Rated Assemblies, I’m looking at: What do I do when access door hidden above hard ceiling? 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 bury access behind duct, insulation, grid, hard lid, wall, lights, or other trades.
