Stop if

Hold point on duct leakage test preparation: 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 use mastic as temporary cap. Don't leave access doors unsealed. Don't pressurize without verifying openings.
