Fire
Hose Testing Standard Operating Guidelines
Download this page as a PDF
The purpose of this guideline is to explain the proper procedure for
the testing of Fire Service Hose. This procedure outlines the National
Fire Protection Associations (NFPA) Standards 1962, "Standard for the
Care, Use and Service Testing of Fire Hose Including Couplings and Nozzles."
This guideline will be followed and accepted by all employees of Safety
1st Fire Hose Testing.
-
Section One -
General
Operating Guidelines:
- The
length of any hose to be tested shall not exceed 300 feet.
- Hose
shall be laid out in as straight of a line as possible.
- All
fire service hose shall be tested. This includes supply beds, pre-connects,
hose bundles and rolls.
- All
hose shall be pre-inspected prior to testing. All couplings will be
checked for damage/slipping. Gaskets will be checked for damage or
if they are missing. The outer jacket will be checked for damage.
If for any reason, one of the above is found, the hose is removed
and marked out of service.
- Each
hose will have an Identification Number assigned. If there is a numbering
system in place, those numbers will be used accordingly.
- If
there is no identification number assigned, each length of hose shall
be given one.
- All
hose shall be repacked to the hose department's SOG.
- It
is the responsibility of the customer department to supply an Apparatus
Operator for the duration of their hose testing session. Safety First
Fire Hose will not at any time directly operate a department's apparatus
or pump.
-
Section Two -
Testing
Procedures:
The following procedures defined in this guideline shall be used when
hose is service-tested using a hose testing machine.
- The
condition of the hose tester shall be thoroughly checked before each
testing session and before the machines is used after being transported
to a new testing site.
- The
hose testing machine shall be carefully examined for damaged components
that might fail during the test.
- If
any damage is discovered, the hose testing machine shall not be used
until the damaged component(s) are repaired or replaced.
- A
pressure leak integrity test shall be preformed on the machine to
determine whether the pressurized outlet side of the machine and its
related components are leak free.
- The
fire hose outlet connection(s) of the machine shall capped or otherwise
closed.
- Pressure
shall be applied through the machine using integral pump to a level
that is 10% higher than the highest service test pressure needed for
the hose to be tested.
- The
pressure shall be held for 3 minutes with the pump turned off.
- If
leaks are detected, the testing machine shall not be used until leaking
component(s) is repaired/replaced.
- The
test gauge that is used to read the test pressure shall have been
calibrated within the last 12 months.
- The
test layout shall be connected to the outlet side of the water supply
valve on the hose testing machine.
- With
the air bleeder open, the pressure shall be raised gradually to 45
PSI (± 5 psi) (3.1 bar ± 0.35 bar or 310 kPa ± 35kPa)
- After
the hose test layout is full of water, all the air in each hose line
shall be exhausted by raising the discharge end of each hose line
above the highest point in the system.
Warning: Take care to remove all, air from the hose before the valve
in the test cap is closed and the pressure is raised. The development
of test pressures introduces a serious accident potential if air remains
in the system.
- The
test cap valve shall be closed slowly, and then the outlet water supply
valve shall be closed.
- The
hose directly in the back of the test cap shall be secured to avoid
possible whipping or other uncontrolled reactions in the event of
a hose burst.
- With
the hose at 45 PSI (± 5 PSI) (3.1 bar ± 0.35 bar or 310
kPa ± 35 kPa), it shall be checked for leakage at each coupling
and the couplings tightened with a spanner wrench where necessary.
- Each
hose shall then be marked at the end of each coupling to determine,
after the hose has been drained, if the coupling has slipped during
the test.
- All
personnel other than those persons required to perform the remainder
of the test shall clear the area. An "ALL CLEAR" signal will be given
by a Safety First supervisor overseeing the test. Safety cones will
be placed 20 feet from test hose layout. This will mark a "SAFETY
AREA." Only authorized Safety First staff will be allowed into the
"SAFETY AREA" during the testing phase.
- The
pressure shall be raised slowly at a rate not greater than 15 PSI
(1 bar or 103 kPa) per second until the service test pressure is attained
and then maintained, by pressure boosts if necessary, for the duration
of the stabilization period.
- The
stabilization period shall be not less than 1 minute per 100 foot
(30 m) of the hose in the test layout.
- After
the stabilization period, the hose layout shall hold the service test
pressure for 3 minutes without further pressure boosts.
- While
the hose test layout is at the service test pressure, it shall be
inspected for leaks.
- The
inspecting personnel will walk the test layout to inspect for leaks,
they shall be at least 15 ft (4.5 m) to the left side of the nearest
hose line in the test layout. The left of the hose line shall be defined
as that side that is to the left when facing the free end from the
pressure source.
- Personnel
shall never stand in front of the free end of the hose(s), on the
right side of the hose, or closer than 15 ft ( 4.5m) on the left side
of the hose, or straddle a hose in the test layout during the test.
- If
the hose test layout does not hold the service test pressure for the
3 minute duration. The service test shall be terminated.
- The
length(s) of hose that leaked shall have failed the test.
- The
test layout shall be drained and the defective hose removed from the
test layout.
- The
service test shall be restarted beginning with the above procedures.
- After
the 3 minutes at the service test pressure, each test cap shall be
opened slowly to drain the test layout.
-
Section Three -
Coupling
Slippage:
- The
marks placed on the hose at both coupling ends shall be observed for
coupling slippage.
- If
the coupling has slipped, the hose shall have failed the test.
-
Section Four -
Hose
Testing Records:
- Each
length of hose shall be assigned an identification number for the
use in recording its history throughout its service life.
- The
identification number shall be marked on the hose at the female end
of all attack hose (1 ¾ in., 2 in., 2 ½ in.). All supply hose (3 in,
4 in, 5 in,) the identification number will be marked at the furthest
end of the hose from the hose testing machine. A black magic marker
shall be used to mark the ID number.
- Accurate
hose records shall be established and maintained.
- Records
of the hose used by the fire department shall be kept as part of the
departments complete equipment inventory.
- Safety
first will provide detailed documentation of all hose that is tested
for each department. The document will provide the ID number, hose
size/length, age (if possible), apparatus location, testing pressure,
and whether the hose passed or failed.
- Hose
Testing Records will be shipped to the customer once payment for fire
hose testing service has been received. Payments are due within thirty
(30) days of receipt of bill.
