I have an existing Fire Rated corridor with the spaces above
it being used as a return air plenum...….The spaces in this
particular area of an existing bldg. are sprinkled.
Q: If there are thru penetrations in the fire rated wall assembly
above the corridor [ i.e. - ducting, conduit, piping, air openings,
etc. ], are the penetrations required to be sealed with an
approved fire caulking or by using fire rated dampers that match
the rating of the corridor, or does the presence of sprinklers
below the ceiling negate the requirement ?
I am looking for the Code sections that require the thru
penetrations to be sealed, or that allow the openings to not be
sealed.
The applicable Codes are the `18 I-Codes...….The NFPA Standards
could also be applicable, ...not sure a this point.
Thanks for your input !
