so in nsfs have been told that we will be losing our 90 feeder hoses and just having 70s instead, whats everyones thought on this?? if we lose them we also will lose our ground monitors but in training we ran a ground monitor off two 70s and it worked really well and kept a good pressure, but also we would have to carry alot more 70s on the appliance to replace the 90s , just curious to what people think bout the 90s, although they a pain to flake i think they are really great
I think Sarah is in the UK, so I'm not entirely certian, but in Australia:
90mm = LDH supply line. we don't use these, but I think they are 3.5 in diameter
70mm = 3" hose with 3" couplings - supply line
65mm = 2 1/2" with 2 1/2" couplings - supply, occasionally used for "surround and drown"
38mm - 1 1/2" with 1 1/2" couplings - primary attack line
25mm - 1" with 1" couplings (used only for mopping up brush fires)
Branch = nozzel
appliance = pumper
Don't worry Ben, I've been here for years, and I still have no idea what the hell anyone is talking about!
