4-20. INITIAL ADJUSTMENTS, CHECKS AND SELF TESTS. - continued
NOTE
Certain fittings are rated at 75 psig maximum. These items are not to be exposed
to test pressure above 75 psig. They can be isolated or removed during the test.
c.
Test Pressure Source. Test pressure can be supplied from any source capable of holding the test pressures.
The 600 gpm hoseline pump is suitable for testing with water or fuel. An air compressor must be available to proceed with
an air pressure test.
CAUTION
Under no conditions are the fabric collapsible tanks to be subject to the air test
pressures. Remove all connecting hoses to tanks to prevent this. Entry of air to
the fabric tanks can exceed the tanks venting capacity, inflate, and possibly
rupture the tank.
NOTE
All test media incompatible with the particular fuel service designated for the
system tested, must be drained from the system before it is placed in service.
d.
Preparations for Testing. The following actions should be taken to insure that the test runs smoothly.
(1)
Be certain that there are sufficient gaskets, repair equipment, etc. available.
(2)
Have caps and plugs available to blank off section under test. Valves in the system may be used to isolate
hose sections as necessary.
(3)
When testing with fuel:
(a)
Locate fire suppression equipment near the testing area, and be sure that it is in operating condition
(when testing with fuel).
(b)
Make sure to have a tank vehicle and drums available, in case a section has to be drained (when
testing with fuel).
(c)
See that shovels and materials to dig and line a pit are al the test site in case there is a break and
spill (when testing with fuel).
(4)
After all the TPT equipment, hose, valves, and fittings are physically connected, there should be a meeting
of all responsible personnel connected with the testing program. Each phase of the test plan including a communication
plan shall be discussed and reviewed. Prior to filling a section for test, a final check should be made to verify the
following:
(a)
All valves are in proper position for filling.
(b)
All hoses, valves and fittings connections are tight. Valve packing glands tight.
(c)
Pumps are in good working condition.
