Hospital Ocupancies NFPA 13 02

Hospital Ocupancies NFPA 13 02

Hospital Ocupancies NFPA 13 02

(OP)
New Hospital how would you classify the following based on NFPA 13, 02

Mechanical Rooms: Ord Gr 1 or 2?
Diesel Generator Room within mechanical room: Ord Gr 1, 2 or EX Haz 1 or 2?

Day tank is about 150 gallons for a generator.

I am thinking mechanical rooms should be Org Gr 1 but the Generator Room should be Ord Haz Grp 2 or higher.

Current design is all Ord Grp 1.

Thanks

Tom

RE: Hospital Ocupancies NFPA 13 02

Mechanical rooms tend to also become a storage area for supporting the MEP folks. I would suggest OH2.

You are well protected with a generator room designed for OH2. The fuel (if stored) should be in a UL 142 aboveground storage tank, which has minimum 0.25 inch carbon steel walls and a 0.37 inch carbon steel head. If it's a sub base tank, the metal thicknesses are even greater.

My opinion of course...

RE: Hospital Ocupancies NFPA 13 02

how tall are the ceiling in the mechanical room b/c if the room ceiling minus min. clearance is less than 8 feet the ordinary hazard group 2 rating


the generator is whole new issue, ie storage of fuel location of storage, volume of storage, size of generator...   does it contain the switching equipment and electrical panels

ect. ect.


hope this helps
