Hold point on fire damper access door location: 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 without checking manufacturer requirements. Don't assume one size fits all. Don't place where unreachable.
