What do I do when screws or duct liner interfering with damper blade?

Fire/Smoke Dampers, Access Doors & Rated AssembliesHigh-risk starter answer — manufacturer/project/code/AHJ verification required

If you put a screw into a possible fire/smoke damper or blade path, stop now. Do not keep pulling, drilling, or trying to fix it yourself.

Field checklist

Stop work in that area immediately.
Do not drive the screw deeper or keep removing/repairing without direction.
Mark the exact screw/location and take a wide and close photo.
Tell the foreman exactly what happened before anyone covers or tests the damper.

Ask foreman

I may have put a screw into the damper/blade path at [location]. I stopped. Can you look before I touch it again?

Do not

Do not hide the hole, smear mastic over it, force the blade, or pretend it did not happen.

Why it matters

A fastener in a blade path can prevent life-safety equipment from working. The recovery move is immediate honesty and verification.
