Radon mitigation system going through the common wall (residential - house/garage) and through the drywall ceiling of the attached garage with no firestop/collars. Is this the correct code reference? If so what would be an example of “firmly packed with noncombustible material”?
321.08 3(b) Electrical and plumbing components. Penetrations of a
required separation by electrical and plumbing components shall
be firmly packed with noncombustible material or shall be protected
with a listed through−penetration firestop system with a rating
of at least one hour.
