    Management is making sure things are done right. Leadership is doing the right thing. The fire service needs alot more leaders and a lot less managers.

    "Everyone goes home" is the mantra for the pussification of the modern, American fire service.

    I'd be interested in learning why you say that. Granted, it could be done from draft, too, or from hydrants with very low pressure.

    Can't you just gate down your intake line? (just asking, I've never used CAFS other than a Tri-Maxx extinguisher)

    I stand corrected - we just recieved a pumper with an on board proportioner. Evidently it is not a CAFS.

    I know of a department that received proposals for pumpers last month. Their specs had an option for a 200CFM CAFS system with five discharges. The lowest price was $47,000 and the highest was $56,000.

    It easier to have a consistent CAFS flow when using tank water, which is fed at a constant, calculated rate versus trying to figure out how much to gate the intake back to get the right flow.

    Like I said, I had the onboard proportioning system and the CAFS's intertwined in my head.

    Still seems high - even for a CAFS system. I doubt it is worth the price in urban firefighting environments where water systems are good and your 2nd, 3rd, & 4th due are less than 6 minutes away.

    When we built ours it was a $22k upgrade to add the 200 cfm eclipse system.
    So with inflation and material cost increases over the past 13 years, would probably be at least $35-40k in todays dollars.

    It's biggest benefit is for rural depts without a city main to tap into every hundred yards or less.
    It extends the water we bring to the scene by removing BTu's and absorbing more than straight H2o.

    I've seen room & contents extinguished with 50 -75 gallons of water using CAFS.

    We Did a training burn on a large 200 yo farmhouse for a neighboring career dept that was looking at buying Cafs on new trucks.

    Some of the old dinosaurs had to stand on the engine deck & watch the flow meters to be convinced at how effective it was in knockdown & extinguishment.

    After a dozen interior room burns they decided to light it off. We coated the 60' X 80' barn exterior with sticky foam and kept it recoated.
    45 minutes later the big barn was ready to fall down and we still had the vinyl siding intact on the exterior. Barn basically collapsed inside it's own footprint.

    I did have to gate the electric intake back as they had 80 psi residual coming off their 12" hydrant mains, in order to keep my rpm's up to power the compressor at speed.
