My concern is that I may be overlooking a standard or code or something that might turn around and bite me. My next move will be as you suggest, call the guy that makes it! Glad you brought up the alcohol resistant feature. Thanks Craig.

Only mention of specifics is that the foam concentrate piping NOT be galvanized. Some of the concentrates can have a somewhat corrosive nature to them. Consult the manufacturer of the foam you intend to use. Foam concentrate ratio (3% or 6% are typical) are dependant on the hazard being protected. Again it's best to consult with the mfgr. Also they can tell you the specific design density to use and whether you need air aspirating type sprinklers or standard heads will be suitable. Once you give them the MSDS on the chemical to be protected they will also tell you whether you need Alcohol Resistant or standard AFFF. _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
