Question about nfpa 13. Hvac metal workshop sprinkler system.

Question about nfpa 13. Hvac metal workshop sprinkler system.

Question about nfpa 13. Hvac metal workshop sprinkler system.

(OP)
Im designing a sprinler system for a hvac metal workshop, it will have some lockformer machines, a duct fabric line and a vulcan cut table. Ive read in nfpa 13 that a metal workshop should be classified as a occupancie Ordinary hazard 2, but i have the concern that the ceiling its pretty high, like 23 feet.

For the occupancies i dont see any regulations for the maximun height of the srpinkler system?? can anyone give me some adivice on this??? Thanks.

RE: Question about nfpa 13. Hvac metal workshop sprinkler system.


There is no maximum height of sprinklers for areas protected using the occupancy hazard design approach..  This only comes into play in high piled storage occupancies.

There was a thread on this about 2 or 3 weeks ago that goes into further details about the theory.  

My advice: drive on with your OH2 @ 23 ft for this application.
