NFPA 15: Exposure protection during exposure fire?

NFPA 15: Exposure protection during exposure fire?

NFPA 15: Exposure protection during exposure fire?

(OP)
Hello, I have to translate a standard based on sections from NFPA 15 (Fixed Water Spray Systems) and there is one term I am having trouble with.

The section pertaining to Exposure Protection says this:

"A system for exposure protection shall operate as intended for the anticipated duration of the exposure fire."

My main problem here is finding the definition of an "exposure fire". Most sources suggest that "exposure fire" refers to a fire resulting from exposure to radiant heat from another fire. And this is why I find the statement confusing, as I would have thought that the exposure protection system was required during the original fire, precisely, in order to prevent any exposure fires. Obviously, having exposure protection during an exposure fire is equally important to prevent subsequent fires, but I would assume the standard would recommend tackling the original fire first.

Any help on the exact meaning of this sentence would be greatly appreciated, many thanks!

Does the appendix a.7.4.1 answer your question???

Hi, thanks for the reference, I found a link to that appendix and yes things are clearer now. It uses "exposing fire" instead of "exposure fire", which confirms that it refers to the original fire. Thanks!
