QUOTE(stugray @ Jan 16 2015, 08:52 PM)  QUOTE(Mike Bellis @ Jan 16 2015, 09:32 PM) I'm itching to pull the handle to see what it does. (IMG:style_emoticons/default/evilgrin.gif) I just don't want to clean the mess. (IMG:style_emoticons/default/dry.gif) An ounce of prevention... I hope I never need it, but it's there just in case. My brother installed one in his TR4 and triggered it by accident. I wasnt there but he said IT SURE WORKS! and that it was easy to clean up. There was no evidence afterwards. I can attest to AFFF's easy clean-up. Just hose it down and move on. (IMG:style_emoticons/default/beerchug.gif) No less than 2 times during my tenure aboard the USS Carl Vinson (CVN-70), the on-board AFFF system was accidentally triggered by a dork in the fire control room. Each time an entire hangar bay (approx 250'x150') was flooded about 2' (FEET) deep in AFFF. . . (IMG:style_emoticons/default/headbang.gif) The only damage was aircraft with canopies and other electrical bays open at the time due to water getting in. (IMG:style_emoticons/default/headbang.gif) I have also done extensive fire training with CO2, Halon, chemical agents and AFFF. AFFF without a doubt is the ONLY agent that suppresses a re-flash. Halon works like magic to put out a fire in an enclosed/partially enclosed space, but AFFF works almost as fast and only AFFF guarantees that it won't re-flash. In a pool of fuel 60' in diameter and about 1" deep, AFFF will not allow a reflash. Dry chemical extinguishers will destroy your motor through corrosion. No matter how fast you hose the agent off, it will instantly flash rust every piece of aluminum it touches (especially carbs). It's amazing how fast it corrodes a motor. Personally, I would rather have the car burned by the fire than deal with the never-ending corrosion that dry chemicals cause. I would encourage anyone to test a chemical extinguisher on a junk car part and see how fast they are ruined. I'm going to be installing an AFFF system on my Squareback when the time comes. I carry CO2 now. |
