Chapter 7 Aerial Apparatus Driver/operator

Front 1

What is pehaps the most important aspect of preparing an aerial device for use?

Back 1

Apparatus stabilization

Front 2

The theorectical safety zone that surrounds the center of gravity on an aerial apparatus.

Back 2

Gravity circle

Front 3

Setting the stabilizers n one side of an apparatus shorter than the stabilizers on the other side; usually done when access for full stabilization i restricted.

Back 3

Short-jacking

Front 4

What are some of the more common stabilizers?

Back 4

- Straight jacks that extend down from the chassis
- A-frame, scissor, or X-style stabilizers that extend down and away from the chassis at an angle
- Box stabilizers that extend straight away from the truck and have jacks that extend straight down to the ground.

Back 5

a long, mournful complaint or lamentation; a list of woes

Front 6

Two-piece aerial apparatus stabilization device consisting of an arm that extends directly out from the vehicle and a lifting ack that extends from the end of the extension arm to the ground.

Back 6

Box stabilizer

Front 7

The PTO should should not be engaged until the aerial apparatus has been what?

Back 7

Positioned in accordance with the conditions on the scene.

Front 8

Pneumatic systems require anywhere from __-___psi air pressure for the PTO to be operated, depending on the manufacturer.

Back 8

50-140 psi

Front 9

The type of PTO activation switch varies from manufacturer to manufacturerand may be of what types?

Back 9

- pneumatic
- electric
- hydraulic
- or combination of the three

Front 10

A rotating shaft that transfers power from the engine to auxiliary equipment.

Back 10

Power take-off system (PTO)

Front 11

Before the actual deployment of the stabilizers, the driver/operator should make what quick observations?

Back 11

- Make sure that the PTO engagement light is lit before leaving the cab.
- Ensure that the wheels are properly chocked, if required.

Front 12

Stabilizers move into position I what three ways?

Back 12

1. Those that extend straight down from the apparatus.
2. Fulcrum-types that swing down into position.
3. Box types that first extend outward and then down.

Front 13

When operating on level ground, stabilizers on which side should be lowered first?

Back 13

Makes no differance which side as long as both on each side are lowered before proceeding to the other side.

Front 14

Why should fulcrum stabilizers be lowered to within a few inches of the ground before placement of the stabilizer pads?

Back 14

It allows for correct placement of the pads.

Front 15

What ae the two ways that a truck can be uneven and which one is easier to correct?

Back 15

- Longitudinally
- Laterally which is easier to correct

Front 16

Correction of lateral uneveness can be achieved on grades up to what?

Back 16

5-6%

Front 17

Most manufacturers of aerial devices recommend that the stabilizers on which side f the vehicle be lowered first?

Back 17

The uphill side

Front 18

When an aerial apparatus is operated on lateral uneveness, which side is preferable to operate the aerial device over?

Back 18

Over the uphill side

Front 19

Where should the aerial device be operated when operating on longitudinal unevenness?

Back 19

Either directly over the front or the rear of the apparatus.

Front 20

Whenever possible, the driver/operator should avoid placing stabilizers where?

Back 20

- Curbs
- Sidewalks
- Parking lots
- Water valve covers
- Other similar obstructions

Front 21

On uneven terrain, how should stabilizers be raised?

Back 21

In reverse order of lowering.

Front 22

When stabilizing a tractor-trailer aerial apparatus, the maximum stability occurs when the angle of the tractor is is how many degrees from the centerline of the trailer?

Back 22

60 degrees

Front 23

On a tractor-trailer aerial apparatus that is jackknifed, which side of the apparatus should the aerial device be operated on?

Back 23

Toward the outside of the angle

Front 24

What is the best way to place a tractor trailer apparatus for aerial operations?

Back 24

- Approach the objective building untl the turntable is right next to it.
- Turn the wheels of the tractor sharply toward the left or right of the parking area and pull the truck sightly forward.
- Turn the tiller wheels sharply toward the building and back the truck slightly toward the desired objective, it produces the desired angle between the tractor and the trailer.
- Set all brakes once in position, including the one for the trailer axle, and further stabilization may be employed.
