1. During MWS apparatus service testing the atmospheric air temperature
should be between ANS >>> 0° F and 100° F
2. When testing the priming device on MWS apparatus with a fire pump with
a capacity of less than 1500 GPM the priming device should be able to create
the necessary vacuum in 30 seconds to lift water 10 feet through. ANS >>> 20
feet of hard suction hose.

, 3. Identify four pre-service test for an MWS apparatus equipped with a fire
pump ANS >>> Road test, independent pump certification test, hydrostatic test,
purchase acceptance test.
4. When performing a vacuum service test, once the engine is turned off, the
column of mercury should fall no more then. ANS >>> 10 inches in 5 minutes.
5. NFPA 1911 requires an MWS apparatus equipped with a fire pump to be
serviced tested ANS >>> ANS >>> At least once a year or when it has undergone
extensive pump repair.
6. Periodic documentation should capture things such as ANS >>> ANS >>>
Safety inspections.
7. And MWS apparatus may have a steering system problems if the steering
wheel can be rotated without moving the front tires more than ANS >>> 10°
8. The pressure control service test measures pressure control devices at
three different points. They are ANS >>> ANS >>> 90 psi, 150 psi, and 250 psi.
9. Think you understand the characteristics of an MWS apparatus?What is
the best explanation for characteristics of an MWS apparatus? ANS >>> An
individual personality-each apparatus may perform, react, and handle differently.

, 10. Personnel must be seated and wearing their seatbelts before the MWS
apparatus begins moving except when. ANS >>> Loading the hose back on to
the MWS apparatus.
11. In order to properly drive on a downgrade slope you must execute four
steps.Downshift before entering the grades, make sure the MWS apparatus
remains in gear, use brakes and low gears. ANS >>> Limit the engine RPM-below
redline.
12. When performing drafting operations, for a pump to operate it it's rated ca-
pacity inches of water must be above a traditional strainer. ANS
>>> 24.
13. The definition of lift is ANS >>> ANS >>> The vertical distance from the surface
of the water to the middle of the intake.
14. It's important to monitor the water level in the onboard tank because ANS
>>> You need to know if the incident requires additional water before the tank is
empty.
15. The correct equation for determining elevation pressure loss or gain is AN
>>> ANS >>> -
EP = 0.5 x H
