Just a word of caution. When you are using 23.4.4.1.1.4, you also have to have additional flow added in, as per the corresponding 23.4.4.1.1.5 (see A.23.4.4.1.1.4).

From a performance perspective, I always liked the “double density” approach where you prove the required density for the hazard that mostly characterizes the use and then a smaller hot spot for the more hazardous aberration. So EH2 per Chapter 11, and also a .6/900 sq. ft. or something like that.

Reference NFPA 13: 12.3 for that requirement. Also, don’t forget the issue of complying with 23.4.4.1.1.4.

The new tenant intends to store two emergency disaster management trailers in this space. However, along two walls, they want to put a 3-teir rack with storage up to 20’ in height. TOS in the center of the unit is 23-9. The racks will contain a mix of group A plastic, emergency supplies in plastic totes, with lids, on non-combustible pallets. Do I really have to upgrade this entire space from OH II to .6/2000? Do I tell them they should just not store over 12’?
