interveining wall:

Question asked by wsemien on Dec 20, 2016

From my understanding NFPA 99 required an intervening wall between the zone valve box and the outlets it controls (whereas the wall would completely separated both components).  The 2012 edition of NFPA 99 appears to allow the zone valve box to be installed in an open ward/suite as long as the zone valve box is not in the line of site of the outlets being served.  I feel that this arrangement will expose a first responder to a hazardous condition in the case of fire.  Will this be revised in future editions of NFPA 99?  And if it will not be revised, please provide me with a detailed explanation on how this can be accomplished without placing someone in harms way.
