Q

What is the “AIR COMPRESSOR CUT-IN AND CUT-OUT” test?

Q

What is tire “rapping” and what is it not recommended for? what is it good for?

A

hitting the tires with a mallet to listen to the difference in sound. It is not good for determining psi. It is helpful in determining if one of the duals is flat or low in pressure

Q

Automatic tire changes may not be effective when?

A

Snow depth of 3”-6”
Slow speeds
Reverse operation

24
Q

How much “free play” is allowed in a steering wheel?

A

No more than 10 degrees in either direction

25
Q

As a rule of thumb, the fuel level should be at or above how much?

A

3/4 tank

26
Q

Hearing protection should be worn if personnel will be exposed to noise levels in excess of what?

A

90 decibels

27
Q

What does a “load sequencer” do?

A

turns various lights on at specific intervals so that the start-up electrical load for all of the devices does not occur at the same time

28
Q

What does the “load monitor” do?

A

“watches” system for added electrical loads that threaten to overload system

29
Q

What is “load shedding”?

A

the shut down of less important electrical equipment to prevent electrical overload from happening

30
Q

What are the two most important safety inspections that the driver/operator will perform?

A

Steering

Brakes

31
Q

What does an “air pressure protection valve” do?

A

prevents the use of the air horns and other unnecessary peripherals from being operated when the pressure in the air reservoir drops below 80 psi

32
Q

How often should the apparatus brakes be thoroughly tested?

A

once a year

33
Q

The parking brake must hold the apparatus in place on a ____ % grade.

A

20%

34
Q

How do you test “air leakage rate?”

A

With air tanks full, shut off engine and note loss of pressure. It should not exceed 2 psi per minute. Then depress pedal to floor (or not less than 90 psi). After it settles, not pressure loss. It should not exceed 3 psi per minute

35
Q

How do you test “low-pressure warning signal?”

A

Engine on or off. Pump brakes to reduce pressure. Warning should sound before the pressure drops to less than 60 psi.

36
Q

How do you test “spring brakes (parking brake) for automatic activation?

A

Pump the pressure down to about 40 psi or below. The parking brake switch should automatically pop out, engaging the spring brake

37
Q

How do you check the “rate of air pressure buildup?”

A

Engine at normal rpm, pressure should build from 85 psi to 100 psi within 45 seconds

38
Q

How do you test “service brakes?”

A

Apparatus moving forward at 5 mph. Apply brakes firmly. Note pulling, delays, or noises

39
Q

How do you test the “parking brake?”

A

Stop vehicle, set the parking brake, and try to move forward in a low gear–should not move

40
Q

How do you test “slack adjusters?”

A

Park on level ground and chock wheels. Release parking brake. Pull firmly on slack adjusters. If they move more than 1” they are out of adjustment

41
Q

If the apparatus has a tilt cab and oil, coolant, and other fluid levels can be checked through a access panel, how often should you tilt the cab for a full inspection?

A

at least weekly

42
Q

As a minimum, a driver/operator should check the following items in the engine compartment:

A
  1. engine oil level
  2. engine air filter
  3. emergency shutdown
  4. exhaust system
  5. coolant level
  6. cooling fan
  7. windshield washer fluid
  8. battery condition

  15. hoses and supply lines
  16. electrical wiring
  17. steering linkage
43
Q

What type of explosive gas do batteries produce?

A

hydrogen

44
Q

What position should the aerial device and the stabilizers be in when checking and adding hydraulic fluid to the system?

A

in the stowed position

45
Q

What two purposes does the aerial operation inspection serve?

A
  1. ensure that the aerial device is in proper working condition
  2. serves as a review
46
Q

Why is it not advisable to rotate the device and extend the device at the same time?

A

it overtaxes the hydraulic system.

47
Q

Apparatus tests can be grouped into what two groups?

A
  1. preservice tests

2. service tests

48
Q

Where are preservice tests conducted?

A

usually at the manufacturers facility

49
Q

Any person who is actually performing nondestructive testing must be certified as what?

A

American Society for Nondestructive Testing (ASNT) Level II NDT technician

50
Q

Load testing is a good indication of what type of load?

A

Static (nonmoving)

51
Q

What two common fire ground occurrences are not accurately tested when static load tests are conducted?

A
  1. operation of the aerial master stream–nozzle reaction

2. impact loading the tip

52
Q

Common types of NDT (nondestructive testing) that may be used on aerial devices:

A
  1. magnetic particle inspection
  2. conductivity readings
  3. liquid penetrant testing
  4. ultrasonic inspection
  5. radiographic testing
  6. hardness testing
  7. acoustic emission inspections
53
Q

Hardness testing is most commonly used on what type of aerial device?

A

aluminum aerial devices and components

54
Q

Ultrasonic inspection is performed on what components?

A

bolts and pins

55
Q

If the apparatus has a pump, an important acceptance testing issue arises when the agency purchasing the apparatus is located at and altitude in excess of what?

A

2000 ft
