Stop if

Hold point on ductwork insulation at fire damper: I have the location, photo, drawing/detail, and what I checked. Who should verify before this gets cut, drilled, covered, lifted, connected, or signed off?

Don't insulate through fire damper sleeves. Don't assume insulation can pass through rated assemblies.
