Exposed to weather would exclude something inside a building. If it's outside it's subject to exposure to humidity, rain, salt air, etc., any condition that's not as controlled as the inside of the building. Seems pretty black and white.

'02-8.15.3.2.3 Where corrosive conditions exist OR the piping is exposed to weather...... So I guess it depends on the definition of "exposed to weather". One could say outside period. Bobby is in FL, I imagine ambient air is a little moister and perhaps saltier even inland than here in the flooded tundra. Or I guess it could mean gets rained on so with a cover maybe not exposed to weather. I know open parking ramps don't fair well here with black nor do wash bays inside. Generic store front canopy a little grayer. Chris Cahill, P.E. Fire Protection Engineer Sentry Fire Protection, Inc. 763-658-4483 763-658-4921 fax Email: [email protected] Mail: P.O.

Is there somewhere it states the pipe and fittings are to be corrosion resistant (ex. Galv.)? I thought somewhere it stated for preact it had to be regardless, but I can't find that either. Maybe I'm pulling an old spec from a project out of my brain as the last two I've done have required galv. piping per the spec book. Bobby Gillett Sr. Project Manager Key Fire Protection, Inc.
