Foam is not foam. Some are kick-ass, others are a bit lack- luster. Some have environmental clean up issues (some fluoro-foams in particular). Some low-priced foam may be discounted as it is approaching its intended shelf life.
If we use enough detergent soap, we can put out a tank fire, but who would want to use that much? Better to buy a smaller quantity of quality foam. It is realized fires requiring foam extinguishment are rare, and so in consideration of that probability, we may buy cheaper foam and fulfill the letter- of-the-standard with regard to checking the boxes on foam suppression quantities. A big fire in a large tank (e.g. > 60 ft diameter) will not care what boxes were checked, however. It takes quality foam (and the appropriate specs to assure it is acquired) to put out big tanks of flammable/ combustible liquids using recommended application rates in the letter-of-some-standards. scot deal excelsior fire engineering _______________________________________________ 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)
