tough to say, as I don't have a complete picture, but I am sure about feeling stronger over an ounce of prevention versus a pound of cure.
Personally, I would double or treble the NFPA 11 RDD for the entire covered area. Another approach is to double the quantity. Even if you extinguish the fire before going into extra innings with your foam, we still we need that foam for control of the fire AFTER it is extinguished. Cool down and suppression of vapors during mop-up. Furthermore, if the fire involved any significant spilling or spraying liquid, the odds are good that foam alone is not going to allow your response teams to go straight home. Bring a shot of Purple-K along with you too. Load the dry-chem for several 8 lb/sec discharges for 5 second durations. There are some excellent tools for putting this dry chemical right where you want it, and it is fired simultaneous with the foam. Works wonders on overturned tankers at roadway disasters, too. 12,000 gallons of Class II liquids may not be in the same strategic ballpark as a 4 million gallon tank of the same, but without the right tools, a fire in a 12,000 gallon tanker still will make me look like the fool who was sleeping in school. scot deal Excelsior Fire Engineering updated their loading rack cover for tanker trucks, the old rack has a foam fire protection system. The facility did not remove the old smaller rack partial rack cover or upgrade the foam system. will this cause fire protection problems. _______________________________________________ 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)
