Identify FIVE requirements for a MWS apparatus that 1. An MWS apparatus equipped with a fire pump must have a tank to pump line
can be found in NFPA 1901 at least two inches in diameter and be capable of supplying the pump with 500
GPM until at least 80% of the tank is emptied.
2. An MWS apparatus must be equipped with at least one external fill
connection connected into the tank that allows the tank to be filled at a
minimum rate of 1000 GPM.
3. The external fill connection should be equipped with a valve, strainer, and a
30 degree elbow.
4.Valves that are three inches or larger must be of the slow closing design.
5. An MWS apparatus must have at least three large tank discharges capable of
discharging 90% of the tank volume at an average of 1000 GPM.
When Checking the left front or right front side of the saddle tanks
fire apparatus, don't forget to inspect the:
Daily inspection Ensure auxiliary fuel tank is full
Operate pump primer
Inspect auxiliary winterization system.
, Weekly Inspection Clean intake strainers
Pre-service pump certification test are conducted by: An independent testing agency
When using a static body of water as your water source 10 Feet above
during fire apparatus service testing, the water surface
must not be more than___ feet above the centerline of 4 Feet deep
the pump intake and the water must be at least _____ feet
deep.
If the engine speed check proves the MWS apparatus is Stop the testing until the problem is corrected.
running at a different speed than what which it was
originally rated, you need to?
A year has passed and its time conduct the annual Connect 20 Feet of the hard suction hose to the pump intake connection.
vacuum test on your departments MWS apparatus.
You're following the procedures for conducting the
vacuum test and you've already checked for and
removed foreign matter from the hard suction hose. The
next step to perform while conducting the vacuum test
is to:
When conducting a priming device test and using a 30 seconds
pump of less than 1500 GPM, the priming device should
be able to create the necessary vacuum in ____ seconds
to lift water 10 feet through 20 feet of hard suction
hose.
Place the steps for conducting a pumping test in the 1. Gradually speed up the pump until the net pump discharge pressure is 150
correct order. PSI
2. Use a pitot tube or a flow meter to check the flow of water at the nozzle.
3.Record six different readings at 5-minute intervals for a total of 20 minutes.
4. Set the net pump discharge pressure to 200 PSI.
5. Set the net pump discharge pressure to 250 PSI.
Pressure Control Test 1. Engage the pump and set it to the pump capacity.
2. Set the pressure control device.
3. Close the discharge valves.
4. Note the pump discharge
The three parts of the pressure control test require you In no less than 3 seconds and no more than 10 seconds
to close the flowing valves one at a time:
