Chapter 6 Fire Hose, Appliances, and
Nozzles
1/2 inches or inch an 1 3/4 - ANS-Most common fart apartment to use as primary attack line
for most fires
100psi - ANS-Standard operating pressure for fog-stream
200 pounds - ANS-When I hoses charge and filled with water it my way as much
as______per hundred foot of length
250 GPM - ANS-2 1/2 inch attackers consider to deliver a flow of approximately_____
30 pounds - ANS-50 foot length of 2 1/2 inch hose where is approximately
40 GPM to 50GPM - ANS-1 inch booster hose is in the range of
50psi or 75psi - ANS-Low pressure nozzle operate
600 feet to 1250 feet - ANS-Typical fire engine they carry anywhere from__________of
supply hose
90 to 225gpm - ANS-Automatic nozzle
adapters - ANS-used for connecting hose couplings that have the same diameter but
dissimilar threads.
adjustable-gallonage fog nozzle - ANS-allows the operator to select a desired flow from
several settings by rotation a selector bezel to adjust the size of the opening. Once a setting
is chosen, the nozzle will deliver that rated flow as long as the rated pressure is provided at
the nozzle.
Attack hose (also known as an attack line) - ANS-used to discharge water from an attack
pumper onto the fire.
automatic-adjusting fog nozzle - ANS-can deliver a wide range of flows. As the pressure at
the nozzle increases or decreases, its internal spring-loaded piston moves in or out to adjust
the size of the opening. Amount of water flowing through the nozzle can be adjusted to
maintain the rated pressure and produce a good stream
ball valves - ANS-used on nozzles, gated wyes, and engine discharge gates. consist of ball
with a hole in the middle. discharge valves most commonly found on fire pumps
booster hose (booster line) - ANS-reel of 3/4" or 1" hard rubber hose
butterfly valves - ANS-often found on the large pump intake connections where a hard
suction hose or soft sleeve hose is connected. Opened or closed by rotating a handle for
one-quarter turn
cellar nozzles and Bresnan distributor nozzles - ANS-used to fight fires in cellars and other
inaccessible places such as attics and cocklofts. nozzles discharge water in a wide circular
pattern as the nozzle is lowered vertically through a hole in the cellar.
double-female adapter - ANS-used to join two male hose coupling
double-male adapter - ANS-used to join two female hose couplings
fire hose appliance - ANS-any device used in conjunction with a fire hose for the purpose of
deliver water.
Fixed-gallonage fog nozzle - ANS-30,60,100, gpm
