Damper open/closed position before startup not verified
Protect damper access and rated assembly requirements: not verifying damper open/closed position before startup.
High-risk starter answer - stop before covering, blocking, fastening, modifying, insulating, or closing anything around a fire/smoke damper, ceiling radiation damper, access door, or rated assembly. Before startup or turnover, the damper position/function needs to be verified by the responsible person.
Ask when access is missing/blocked, damper type is unclear, rated construction is involved, or manufacturer/AHJ detail is not known.
Watch out
Do not treat damper or rated-assembly work like normal duct.
Check
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.
Ask who is checking operation/status before startup and turnover.
Steps
Identify damper type and label.
Find access side, actuator/handle, and blade path.
Check whether duct, insulation, ceiling, or another trade blocks access.
Focus on the actual issue: not verifying damper open/closed position before startup.
Photograph or mark the condition if someone else needs to approve it.
