John, This is an interesting point you brought out. I know we preach the "A" rating on extinguishers for the every reason you state. However we also specifically permit a 1.25 lb net Halon (1211) or equivalent. Halon is largely no longer available but the primary alternative, Halotron 1, does not get any A class rating until the extinguisher is a net 11 lb unit and then it is 1-A, 10-BC. And from what I can find about Halon 1211 it did not get any class A rating until the net is in the 9-17 lb range.Mopar 151 wrote: Does that Halon have any type A (combustibles) rating? A lot of extinguishers are only rated BC (liquid fuel, electrical), but we require an ABC rating (1A10BC) - because we run in the woods, and we care more for the woods than your car .
This begs the question. How did the 1.25 lb Halon or equivalent become acceptable in our rules? It appears as far back as 2004, probably further, but that is as far back as is available on our web site.
