Hose checks – hose reels are fully unwound and the condition of the hose and valves/nozzles checked. Pressure test – The equipment is filled with water presurised and inspected for any leaks to test the integrity of the reel and hose. Maximum working pressure usually 12 bar so
test pressure is typically 18 bar
.
What is the pressure of a fire hose reel?
The usual working pressure of a firehose can vary between 8 and 20 bar (800 and 2,000 kPa; 116 and 290 psi) while per the NFPA 1961 Fire Hose Standard, its bursting pressure is
in excess of 110 bar
.
What is the maximum pressure of a fire hose?

Hose is one of the basic, essential pieces of fire-fighting equipment.
What is the flow rate of a fire hose?
Typical flow rate for fire hydrant discharge outlets are as follows
5
: 21⁄2-inch discharge outlet:
10 psi – 500 gpm
.
15 psi – 610 gpm
.
What is the minimum flow rate for a fire hose reel with a 19mm hose?
Flow rate should be a minimum of:
19.8 litres per minute
for 19mm hoses.
How many feet of hose is on a fire engine?
The standard for automotive fire apparatus requires pumpers to carry at least 15 feet of hose or
20 feet
of hose. 1200 feet of 2 12 inch or larger hose. 400 feet of 1 12, 1 34, or 2 inch attack hose.
How much PSI does a fire hydrant have?
Fire hydrants are flow-tested at a residual pressure of
20 psi
; therefore, firefighters should understand the typical flow rates of fire hydrants at that pressure.
How much water do you put in a fire hose?
The capacity of a 100-foot length of 1-inch diameter hose is
4 gallons
.
What is the minimum flow rate for a fire hydrant?
The minimum fire flow from any individual fire hydrant shall be
500 gpm
. The minimum flowing pressure at maximum flow shall be 20 psi.
How do you calculate gpm for a fire hose?
The formula to find GPM is
60 divided by the seconds it takes to fill a one gallon container
(60 / seconds = GPM). Example: The one gallon container fills in 5 seconds. 60 / 5 = 12 GPM. (60 divided by 5 equals 12 gallons per minute.)
How do you fit a fire hose reel?
Attach the hose guide to a suitable location about 330 to 350 mm in the side and 330 to 350 mm down the center of the mounting plate.
Lift the reel
to the wall mounting plate. Insert hose through the hose guide and place the nozzle into the bracket. Connect the water supply to the shut-off valve.
What is the distance a hose reel can be located from an exit?
When used in a Class II system, fire hose reels with 1 1/2” hose may be placed as far
as 130 feet apart from
each other (as measured with the “actual length” method).
What is the length of a fire hose reel?
Standard fire hose reels are
36 metres in length
and can provide a jet of water up to 10 meters.
How far can a fire hose shoot water horizontally?
How high can the fire hose shoot? Depending on water pressure, between
75 to 100 feet straight up
. Firefighters on the ground rarely try to reach higher than 40 feet with hoses.
What is the NFPA Standard for fire hose?
NFPA 1962
: Standard for the Care, Use, Inspection, Service Testing, and Replacement of Fire Hose, Couplings, Nozzles, and Fire Hose Appliances.
When can a fire hose not be used?
Hose Reels are suitable for Class A fires: Paper, Textiles, Wood, Most Plastics and Rubber.
Do NOT use on electrical fires
, remember water conducts electricity, so using a fire hose reel on it could lead to electrocution!
