Q

Modern fire department pumpers are equipped with a

A

Centrifugal pump as their main pump

24
Q

Which of the following statements about positive displacement pumps is MOST accurate?

A

They are used as priming devices to get water into the centrifugal pump during drafting operations

25
Q

Which pumps are powered by a gasoline or diesel engine independent of the vehicle-drive engine?

A

Auxiliary engine driven pumps

26
Q

Which pumps are supplied power through the use of a split shaft gear case located in the drive lane between the transmission and the rear axle?

A

Midship pumps

27
Q

Which types of automatic pressure control devices are sensitive to pressure change and have the ability to relieve excessive pressure within the pump charge?

A

Relief valves

28
Q

Which of the following can be opened in order to prevent the pump from overheating?

A

Circulator or bypass valve

29
Q

When transitioning to an external water supply, opening the intake’s gate valve on a charged supply line without first opening the bleeder valve will result in:

A

Air in the supply hose entering the pump

30
Q

How much water should be above a traditional strainer in order for a pumper to approach its rated capacity during drafting operations?

A

At least 24 inches (600 mm)

31
Q

Who should be notified immediately upon indication that the water supply or pumping ability may be unattainable or interrupted?

A

Incident Commander

32
Q

The pumper that should have the largest capacity in a relay operation is the:

A

Water supply pumper

33
Q

The pumper that receives water from the source pumper or another relay pumper, raises the pressure, and supplies water to the next apparatus is called the;

A

Relay pumper

34
Q

The pumper that can be of smaller capacity due to its ability to use acquired energy of previous pumpers in the relay is the:

A

Relay pumper

35
Q

The need for a operation is based on which two factors?

A

Amount of water required and distance between the scene and water source

36
Q

When relaying long distances, if pumpers carrying different diameters of supply hose are to be used in the operation, distances:

A

Must be adjusted to compensate for each size hose

37
Q

Failure to keep water moving when using static water supply during a relay may result in:

A

Loss of prime, thus delaying the operation

38
Q

When putting a relay into operation, the relay pumper’s intake pressure should be maintained at:

A

20 to 30 psi

39
Q

When relay pumpers are equipped with an adjustable intake relief valve, they should be set to 10 psi (70 kPa) above the static pressure of the water system to which it is attached or:

A

10 psi above the discharge pressure of the previous pumper in the relay

40
Q

Once the relay is in operation, the driver/operator of the attack pumper should not attempt to correct minor fluctuations as long as the intake pressure does not drop below:

A

20 psi

41
Q

Relay operations should be shut down first from the:

A

Fire scene

42
Q

During fill operations, it is recommended that the fill site pumper remain in pump with a waste line flowing in order to prevent:

A

Loss of prime and/or overheating

43
Q

Raw foam liquid in its container that has not been mixed with water and air is known as:

A

Foam concentrate

44
Q

When using a static water source to conduct pump performance tests, how far below the surface of the water must the strainer be submerged?

Q

In order for the driver/operator to be ready to mount the turntable and operate the aerial device, hydraulic power must be transferred.

A

From the stabilizer system to the aerial operations system

48
Q

Since most modern tillered aerial apparatus are equipped with stabilization systems capable of securely stabilizing them whether they are jackknifed or not, techniques for jackknifing are more important to:

Older models of tillered aerial apparatus

49
Q

For which of the situations MUST personnel be safely anchored to a structural feature of the aerial device.

Q

Which of the following is recommended if winds exceed manufacturer’s limits?

Inside the dike that surrounds the affected tanks

52
Q

Which of the following BEST explains why an aerial device should be aimed initially above the victim and then lowered for the rescue

A

Victims may attempt to jump onto the device

53
Q

Which of the following is BEST described as the device that injects the correct amount of foam concentrate in the water stream to make the foam solution?
