Stop if

Hold point on sound attenuator direction and access: 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 cut into or modify an attenuator without manufacturer/project approval. Do not assume it can be flipped.
