So how many true pumps in SACFS?, and who deserves to get one based on risk?
SACFS don't have a designation for a Heavy Pumper.
Anything "Type 2" Pumper and higher meets the requirements for an "Urban Pumper", according to SACFS. As Pip has said, its generally understood that a "Heavy" pumper can spit out 1000gpm. If you look around the country at other services "Ultra Large" and "Super Pumpers" they dwarf the capacity of anything the CFS calls a pumper. (Not that CFS need anything like that, its more for interests sake)
Does a 34P Tanker with Urban Stowage meet the CFS definition of an "Urban Pumper"?
Light Pumper - 1000L/m @ 700kpa
Medium Pumper - 2000L/m @ 700kpa
Urban Pumper - 3000L/m @ 700kpa
24P Tanker - 2000L/m @ [Unspecified] kpa
34P Tanker - 3000L/m @ [Unspecified] kpa
(All shamelessly ripped from the Oct 2010 SOP's Glossary, I really hope there is a better definition out there?)
I do love the manner in which CFS rate their pumps to the recommended operating pressure of the branch, rather than to a figure closer to 'normal' pump operating pressures, say 1000kpa?
How about,how many pumpers with over 3000lpm capacity?. I see a number of Isuzus similar to CFA and FRNSW.
