Typical Waste Water Treatment Plants are classified as F-2 occupancies and don't require fire protection. SO2 is of no consequence as it's not a flammable gas. Unless quantities of it create a change in occupancy classification where the room ends up an "H" occupancy, there just usually is no driver within the plant to warrant fixed fire protection.

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...
