Good afternoon all,
I've been studying since several code sections trying to find out whether a mechanical room needs to be rated or not. Here the facts:
its a 2 story F-4 in NYC (or A-2 as per 2008) fully sprinklered space. prep in cellar, eating an drinking on first floor . Construction Class is IIB.
There is a 30 tonne unit on cellar level, feeding both floors. No combustion.
As far as I know all penetrating ducts have dampers.
My question is if i need a rating on the mechanical room demising walls and door.
It would be great to get some feedback or if someone could direct me to a code section that will answer my question.
Thank you very much!
Have you checked BC 508? If you say all penetrations have dampers that implies you have a fire rated wall, whether is 1hr or 2hr.
