hooking up to a standpipe
advance hos dry
hook up one floor below fire
stage men and equipment 2 floors below fire
set up safety zone
flake extra hose up the stairs
use your own hose

passing hose line up a fire escape requires a ff on each landing
True False
true
remove kinks from hose before entry
true false
true
chock doors while advancing hose
t/f
True
position hose to what when operating hose from ladder
through the rung
hoisting hose charged
tie off bail
person footing ladder cannot do what
help get hose up ladder
always a good idea to have pre set up hose packs for high rise buildings True / False
True
Hose line can become loose if
loose nozzle
unattended nozzle
fire stream
a stream of water or other extinguishing agent after it leaves a fire hose and nozzle until it reaches the desired point
fire streams used to
reduce heat from a fire
protect the ff
protect exposures
always be doing
size up
fire stream considerations
properly developed and aimed
poor steams allow fire to burn
proper stream has volume, pressure, direction
pump water hose nozzle
fire streams need
pump
water
hose
nozzle
low volume stream discharges
<40 GPM
handline streams discharge
40 -350 GPM
master streams discharge
> 350 GPM

one to one and one half times its diameter
velocity
rate of motion of a particle in a given direction
SPEED
