A lot of people have questioned me on why we use CAFS and why I say I will NEVER buy another piece without it. My best answer came at a mutual aid call 2 nights ago.
A 2 story block and frame construction juvenile detention center, used to house around 50 males. Abandoned long enough ago that the trees had grown up on the driveway and blocked access. Fire was through the roof upon arrival of the primary department. Truly exterior attack only.
1- 2000 GPM engine, water, 150' 2.5" to wye, 2- 200' 1.75" lines to building
1- 500 GPM/140CFM CAFS engine, 300' 2.5" to water thief, initial from here was 100' 2.5" to blitzfire and a 200' 1.5" line. Mop up was 1- 200' 1.5" from the end of the blitzfire (yes, nozzle was 600' from pump) in addition to 2-
200' 1.5" (yes, nozzle 500' from pump) lines.
These stats are just from our CAFS engine, which I was running:
Maximum pump pressure 110 psi
Maximum engine rpm 1600 rpm
Foam used: 12 gallon
Water used: 3000 gallons estimated
Time on scene: < 3 hours
Number of rekindles: 2, not where foam was used
That is why I will never buy another rig without CAFS!
