Apprentice question
Stop and ask
Stop. Get direction before you touch it.
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.
['A rated wall penetration is not just a hole to fill with red caulk. The duct, sleeve, wall type, damper requirement, annular space, packing, and firestop system all have to match the approved assembly.', 'If raw duct is touching rated drywall and only caulk is applied, stop and verify the detail. The likely recovery is to back it out, frame/sleeve the opening correctly, use approved packing/firestop, and install retaining angles or damper components as required.']
