When an entire facility does not require fixed sprinkler systems and a single 9x12 room is classified as an "H" occupancy due to non-combustible/flammable gases, corrosives or other non-fire hazard, it is not uncommon to receive a variance for omission of sprinklers for that one room. Requesting relief for providing a municipal tap, run-in, riser and piping for one or two sprinklers for an area where there is no greater fire hazard than any adjacent area is often not challenged by most reasonable AHJ's.

Has occupancy class been determined? SO2 is a hazardous material. Architect Sent from my Motorola ATRIX™ 4G on AT&T -----Original message----- From: Douglas Hicks <[email protected]> To: [email protected] Sent: Mon, Feb 6, 2012 21:27:33 GMT+00:00 Subject: SO2 chemical The city is asking if sprinkler coverage is needed at the sewage treatment plant. Of particular concern is a room (8 x 12) where the chlorine in the sewage is treated with SO2 (sulfur dioxide) so the discharge is rendered safe to be put into the river. The building construction is a combination of wood and brick. I do not know any dimensions of the entire building or other rooms. At present, there is a sprinkler head in the SO2 room, plumbed off the potable water supply. No shut off valves, no gauges, no drains. My initial response is if a sprinkler system is needed, it would be addressed by the city’s insurance carrier. Anyone familiar with a sprinkler in treatment plants? -------------- next part -------------- An HTML attachment was scrubbed...
