What do I do when confusing SA, RA, EA, OA, and MUA tags?

Field checklist

Ask foreman

Can you confirm whether this run is SA, RA, EA, OA, or MUA before I install it?

Do not

Do not install by size alone when the system tag is unclear.

Why it matters

A duct can be the right size and still be completely wrong if it belongs to the wrong system.
