NFPA 13 storage
NFPA 13 storage
(OP)
I have a 13r system design with a group of small 13 residential storage closets in the middle of the building. How to I calculate these closets? These storage closets do not have rated walls separating them and no self closing hinges and have a ceiling height of 9'-0". Do I have to calculate them all together as OH .15 or can I reduce the number of closets to calculate?

If not, I've accepted and OH1 density because it should control the fire and upon water flow, should limit the fire spread beyond the compartment of origin assuming no funky goods like hazmats are being stored.

In certain cases, storage closets are not permitted to be constructed without fire-resistive separation when a NFPA 13R system is employed. A NFPA 13R system is a life-safety system versus NFPA 13 which is a life safety & property protection system.
