Stop if

Hold point on ductwork penetration firestopping: I have the location, photo, drawing/detail, and what was checked. Who should verify before this gets cut, covered, lifted, sealed, energized, or signed off?

Don't install duct through rated assemblies without firestopping. Don't use generic caulk as firestop.
