What do I do when forgetting to mark airflow direction on staged duct?

Measuring, Field Verification & Layout MarksFoundation layout starter — field verify before cutting/loading

Mark airflow direction on staged duct when direction matters. It prevents backwards fittings and confused handoff.

Field checklist

Can I mark airflow arrows on these staged pieces before install?

Do not assume the next person knows which way the piece is supposed to face.

Staged duct gets rotated, moved, and handed off; marks prevent wrong direction.
