Stop if

Hold point on duct liner fire rating: 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?

Watch out

Don't install liner without verifying fire rating. Don't assume all liner is same. Don't use damaged or unlabeled liner.
