Can you confirm airflow direction before I crimp and assemble this run?
I traced airflow from [equipment/source] toward [destination], but this run is not marked. Can you confirm airflow direction before I crimp and assemble it?
Hold point on crimp end and airflow direction: I have the location, photo, drawing/detail/spec section, and what I checked. Who should verify before this gets cut, drilled, sealed, supported, connected, controlled, or covered?
Watch out
Do not point the crimp against airflow, crimp both mating ends, or force a damaged crimp.
Check
room/grid/area
photo of condition
drawing/detail/spec/submittal
what I already checked
what is blocking progress
Say this to your foreman
