Stop if

Hold point on pre-test leak walk: I have the location, photo, drawing/detail/spec/submittal, and what I checked. Who should verify before this gets covered, tested, started, labeled, or turned over?

Watch out

Do not let the test start just because the fan is there. Do not use mastic as a temporary cap. Do not ignore hidden access doors or uncapped branches.
