CDC MWS CCRE
Place the steps for part two of the pressure control test in the correct order: - Answer-1. Set the fire
pump so that it is discharging at a net pump discharge pressure of 150 psi.
2. Reduce the pumping engine throttle until the net pump discharge pressure drops to 90 psi
3. Set the pressure control device to maintain the discharge pressure at 90 psi
4. Close the flowing valves one at a time.
5. The pump discharge pressure should rise no more than 30 psi when all valves are closed.
Two items that should be included on daily MWS records: - Answer-1. Tire Conditions
2. Coolant levels
What re two daily inspection two perfom on a MWS equipped with a fire pump? - Answer-1. Operate
the pump drive control
2. Confirm that the foam tank level is full.
Testing the discharge pressure gauge begins by: - Answer-Disconnecting all preconnected hose lines and
screwing all caps onto their discharges.
What is total stopping distance? - Answer-The sum of the driver/operator reaction distance and the
MWS' braking distance.
, Three things you should do when turning an MWS 180 degrees? - Answer-1. make sure you can see
your spotter
2. Be aware of any obstructions in your line of travel
3. use the side view mirrors equipped on the MWS
When performing the serpentine exercise, you should what? - Answer-Should only travel on one
direction, without striking the obstruction.
Two facts about looping mains in a distribution grid? - Answer-1. They create a constant flow and less
sediment forms in the pipes.
2. They ensure that water flows from two directions into hydrants.
When a fire scene is located down a narrow lane, it is BEST to locate the dump site: - Answer-At the
intersection where the lane meets a thoroughfare.
What is the advantage of using an MWS with a Jet-assisted dump is that: - Answer-The in-line discharge
creates a Venturi effect increasing the water flow through the large tank discharge.
The fill site for a water shuttle operation may be shut down when: - Answer-all MWS have been refilled.
When operating a water shuttle operation involving a fill site pumper with 2 1/2" fill lines, what is the
recommended total number of make and break personnel that should be involved? - Answer-2
When it becomes necessary for the dump site pumper to operate off its tank because the portable tanks
are empty then: - Answer-The attack pumper should be notifies that water loss is imminent.
During an MWS inspection, the lowest acceptable fuel gauge reading is: - Answer-at least 3/4 full
