Quote:Engine typing is basically based on pump, tank and crew size. California finally got on the same page as the rest of the US so we no longer have two separate but similar standards. These are minimums, it is ok to exceed them although that may put it into another class.


Type 1

1000 gpm pump, 300 gal tank, crew of 4. Also requires 1200ft 2.5" (or larger) hose, 500ft 1.5" hose, ground ladders per NFPA and a master stream of 500gpm.


Type 2

500 gpm pump, 300 gal tank, crew of 3. Also requires 1000 ft 2.5" (or larger) hose, 500 ft 1.5" hose, ground ladders per NFPA


Type 3

150gpm pump (@250psi so really 300gpm in most cases), 500 gal tank, crew of 3. Also 1000 ft 1.5" and 500 ft of 1" hose


Type 4

50 gpm pump, 750 gal tank, crew of 2. Also 300 ft 1.5" and 300 ft 1" hose.


Type 5

50 gpm pump, 400 gal tank, crew of 2. Also 300 ft 1.5" and 300 ft of 1" hose.


Type 6

50gpm pump, 150 gal tank, crew of 2. Also 300 ft 1.5" and 300 ft 1" hose.


Type 7

10 gpm pump, 50 gal tank, crew of 2. Also 200 ft of 1" hose.




Type 1 and Type 2 are structure engines


Type 3 is a heavy brush engine with a large (relatively) pump. Must be capable of pump and roll, usually a PTO, but occasionally a large auxiliary engine driven pump.


Type 4-6 are primarily pump and roll rigs (usually have an auxiliary engine driven pump) and differ primarily in tank size. Max GVWs have been added to type 5-7 to help prevent overloading a smaller chassis.


Type 7 are patrol rigs, small pump and tank.
