That is more of the angle that I am asking these questions from : We took delivery of a CAFS engine. We got a house fire. We pulled a 2 1/2" handline, Engineer charged it with CAFS for an interior attack. The foam system did not work, so we got air and water. IT was very hard to handle with not a lot of GPM Flow.
What I am looking for is specifically any department that has CAFS that uses it for sustained interior attacks. I hear a lot from departments that use it for defensive or transitional attacks. The departments that have it and can sustain an initial interior attack have opted to leave it to "Officers Choice". We want to support it and use it correctly. We also do not want anybody to get injured along the path.
Currently if CAFS goes down (you lose the air) we can revert to foam and water and flow from 130-160gpm smooth bore attack. I am comfortable with that. I am more concerned in a situation where we arrive, pull a line go interior and (like it is described) it blacks out the fire quickly. Our members will move in for the kill and I am concerned that we have not addressed the BTU's due to only delivering 95GPM.
I do support CAFS, we have 4 CAFS engines (out of 9 front line engines). We want to use it, we just need some solid information from a dept. that actually uses it and is not a station that does defensive or transitional attacks. I see the use and benefit of that completely.
My other concern is in commercial structures without carpet (hopefully this clears it up). IF we lay into a kitchen fire at the local eatery with a 2 1/2" CAFS line what is going to keep us from looking like ice skaters inside, slipping all over the place. IT seems there would be some hazard in this appication. Meaning- no carpet or other material to absorb the CAFS- NO CAFS for initial operations.
Anyway, we are trying to tackle this currently. We need a proper attack flow (GPM) Some go/no go decision making markers (when to use CAFS when not to use CAFS).
We have checked with some local fire depts. and will continue the hunt.
Good talk here. Hey Lt Anderson! I work with Michael and can vouch for him, he knows his stuff.
I gotta remember the "ice skater" comment, I haven't heard that one yet! Seriously though I have conducted several interior attacks on concrete floors and haven't had any ice skater accidents. I faced more problems from E221 streams though, HA!
