Accurate)
1. an MWS apparatus equipped with fire pump must have a tank to pump line
at least 2 in in diameter and capable of supplying the pump with 500 GPM unit
at least 80% of water in the tank is emptied
2. NMWS apparatus must be equipped with at least one external fuel
connection connected into the tank that allows the tank to be filled at a
minimum rate of 1000 GPM
3. The external fuel connection should be equipped with a valve strainer and
30° elbow
4. valves that are 3 in or larger must be of the slow closing design
5. an MWS apparatus must have at least three large tank discharge capable of
discharging 90% of the tank volume at an average rate of 1,000 GPM Right
Ans - identify five requirements for a MWS apparatus that can be found in
NFPA 1901
saddle tanks Right Ans - when checking the left front or right front side of
the apparatus, don't forget to inspect:
an independent testing agency Right Ans - pre-service pump certification
tests are conducted by:
10,4 Right Ans - when using a static body of water as your water source
during fire apparatus service testing the water surface must not be more
than_____feet above the center line of the pump intake and the water must be
at least____feet deep
stop the testing until the problem is corrected Right Ans - if the engine
speed check provides the MWS apparatus is running at a different speed than
that which it was originally rated, you need to:
30 Right Ans - when conducting a priming device test and using a pump of
less than 1500 GPM, the priming device should be able to create the necessary
vacuum_____seconds to lift water 10 ft through 20 ft of hard suction hose
, And no less than 3 seconds and no more than 10 seconds Right Ans - The
three parts of the pressure control test require you to close the flowing valves
one at a time:
10% Right Ans - The gauge and flow meter test compares flow meter
readings with actual pilot tube readings. The two readings should differ no
more than:
NFPA 1901 Right Ans - The tank to pump flow rate test measures whether
the piping between an apparatus water tank and fire pump meets the
minimum flow standard of:
1. keeps everyone on the team informed about equipment conditions
2. helps determine whether equipment should be repaired / replaced.
Right Ans - identify two most important reasons for maintaining good MWS
apparatus records.
start the engine without a load. Right Ans - an MWS apparatus should be
started with all electrical switches and the OFF position in order to:
20 ft of hard suction hose Right Ans - when testing the priming device on
an MWS apparatus with a fire pump with the capacity less than 1500 GPM, the
priming device should be able to create the necessary vacuum in 30 seconds
to lift water 10 ft through:
1. road test
2. independent pump certification test
3. hydrostatic test
4. purchase acceptance test Right Ans - identify four pre-service tests for
an MWS apparatus equipped with a fire pump
1. priming device
2. hard suction hose
3. pump Right Ans - identify three items that are checked for leaks during
vacuum test.
10 in and 5 minutes Right Ans - when performing a vacuum service test,
once the engine is turned on, the column of mercury should fall no more than:
