DOD MWS cdc
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 correct answersidentify five requirements for a MWS
apparatus that can be found in NFPA 1901
saddle tanks correct answerswhen checking the left front or right front side of the apparatus, don't
forget to inspect:
an independent testing agency correct answerspre-service pump certification tests are conducted by:
10,4 correct answerswhen 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 correct answersif 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 correct answerswhen 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 correct answersThe three parts of the pressure
control test require you to close the flowing valves one at a time:
, 10% correct answersThe gauge and flow meter test compares flow meter readings with actual pilot tube
readings. The two readings should differ no more than:
NFPA 1901 correct answersThe 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. correct answersidentify two most
important reasons for maintaining good MWS apparatus records.
start the engine without a load. correct answersan MWS apparatus should be started with all electrical
switches and the OFF position in order to:
20 ft of hard suction hose correct answerswhen 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
