Do not force or damage the access door without direction.
Photo the door, latch, paint/seal, and surrounding rated surface.
Tell the foreman and ask who owns freeing/replacing/protecting the access.
Track the condition before inspection so it is not a surprise correction.
Ask foreman
This damper access door is painted/seized and will not open. Who owns opening or repairing it before inspection?
Do not
Do not treat damper or rated-assembly work like normal duct. Do not bury access behind duct, insulation, grid, hard lid, wall, lights, or other trades.
Why it matters
Renovation access problems are often GC/painting/scope coordination problems, not apprentice pry-bar problems.
