Field checklist

Look for label/tag, sleeve, retaining angle, actuator, fusible link, or access side.
Do not cover, drill, fasten, paint, or insulate over it.
Use Photo ID or ask the foreman to identify it.

Ask foreman

I see a labeled/framed piece in the wall and I think it may be a damper. Can you identify it before I work around it?

Do not

Do not treat unknown wall hardware like normal duct.

Why it matters

The person who does not know the word damper still needs the stop signal.
