ESFR OK For Non Storage Locations FM Says YES!! NFPA?????

[LCREP]

FM Data Sheet 3-26 FIRE PROTECTION WATER DEMAND FOR NONSTORAGE SPRINKLERED PROPERTIES 7/2011 ED


2.1.1.6 For new or existing Nonstorage occupancies, it is acceptable to use storage sprinklers to protect all
areas of mixed storage and manufacturing, and Nonstorage. Determine the water demand design requirements and evaluate obstructions based on the applicable occupancy-specific storage data sheet.

NFPA 13 2010 says this, yea I know says nothing about non-storage, but this all I can find. Ordinary hazard storage and mics storage has Ord Grp. 1 & 2 designs.

12.6.7 CMSA and ESFR sprinklers shall be permitted to protect
ordinary hazard storage of Class I through Class IV commodities,
plastic commodities, miscellaneous storage, and
other storage as specified in Chapter 12 through Chapter 20
or by other NFPA standards.

So if I have an extra hazard occupancy as per NFPA can I use an ESFR system? Say an injection molding operation with hydraulic fluid?? Looks like FM says yes and NFPA No????

We see this when the spec building is built and ESFR is installed and a non-storage occupancy moves in. What would you do as the AHJ??

Would require system to be check , if it met hazard going in, before answering along with checking listing on actual head used

I would permit it. FMDS are prima facia evidence of compliance in the International Fire Code.

I have a concern in a hydraulic oil fire (as in an injection molding machine) the fire can set off too may ESFR heads since the fire is not going to be controlled or extinguished since it is a 3 dimensional fire. If we had auto shut off of the hydraulic pump say via a water flow switch then maybe. Also what about a flammable liq. operation, say spray painting or dipping, again are we going to get fire control to reduce heat output??
