Raw duct is run through a rated drywall wall with only fire caulk
Do not treat raw duct plus caulk as an automatic rated penetration. Rated wall crossings need the approved sleeve/firestop/retaining detail for that assembly.
Do not rely on random fire caulk to legalize an unapproved rated wall penetration.
Check
Identify wall rating and whether a fire/smoke damper or sleeve is required.
Check approved drawings, firestop submittal, damper instructions, and UL/system detail.
Inspect whether duct is rubbing drywall/framing or missing sleeve/retaining detail.
Photograph before cover and get foreman/GC/firestop direction.
Do not cover until the rated assembly is accepted.

Say this to your foreman
The duct at [location] penetrates a rated drywall wall without the proper sleeve/detail, just fire caulk. I checked the wall rating. Do you want us to pull back and install the approved penetration assembly?
