The incident commander,company officer, or the driver/operator and influence by condition at the scene

Question 3

Long extensions at low angles place the maximum amount of

Answer 3

Stress on an aerial device

Question 4

A good indicator of underground voids are

Answer 4

Manhole covers

Question 5

By facing uphill, the angle of the turntable is decreased there by

Answer 5

increasing capability and stability

Question 6

If the Apparatus is facing downhill the

Answer 6

capability of the Apparatus may be decreased

Question 7

Moderate to high winds impose a

Answer 7

Dynamic load on the aerial device

Question 8

When it is necessary to operate during High wind conditions

Answer 8

The driver should spot the apparatus in a manner that minimize the extension needed.

Question 9

The aerial device may also be position

Answer 9

Over the front or rear of the Apparatus, preferably parallel to the wind direction

Question 10

Keep aerial device ____clearance for High-voltage transmission lines over____

Answer 10

50’ 50,000

Question 11

Stability of aerial apparatus can be improved by

Answer 11

Operating the aerial device in line with the longitude axis(apparatus body)

Question 12

The Apparatus is most stable when the aerial device is

Answer 12

Operated directly over the front or rear of the vehicle

Question 13

And angle perpendicular to the Apparatus is

Answer 13

The least stable position

Question 14

A good Stability occurs at angles up to

Answer 14

90°, but decreases at angles Beyond that

Question 15

Stress may be imposed in both

Answer 15

Static [at rest] and dynamic [in motion]operation

Question 16

Stress in aerial devices is increased when the ladder rungs are operated

Answer 16

non-parallel to the ground or when the apparatus park on an incline and aerial device must operate off the side of the apparatus

Question 17

When an apparatus must operate off an incline

Answer 17

The driver can reduce these stress by spotting the turntable downhill from the point of operation

Question 18

When approaching from the uphill side, the Apparatus

Answer 18

should park pass the building and operate the aerial device from the rear of the truck

Question 19

When approaching from the downhill side the Apparatus should be

Answer 19

stopped short of the building,and the aerial should be operated over to Cab

Question 20

Ideally, the truck should be operated in the uphill position with the aerial device directly in line to reduce stress

Answer 20

true

Question 21

Answer 21

70° and 80° from horizontal

Question 22

As extension increases,aerial loading must_____

Answer 22

decrease

Question 23

Aerials operating at low angle of elevation and at a long extension is at their

Answer 23

weakest operational position

Question 24

Most modern aerial devices are designed to be operated

Answer 24

In the unsupported position

Question 25

If the manufacturer recommends that a device be operated in a support position. The load or the amount of

Answer 25

extension must be reduced for low angles of elevation during unnsupported operation

Question 26

Some of the most dangerous scenarios face by fire fighters are operation on

Answer 26

Highway, interstate, turnpikes, and other busy roadways

Question 27

Consider parking additional apparatus ____behind the shielding apparatus to act as an additional barrier between firefighters and the flow of traffic

Answer 27

150-200 feet

Question 28

Most railroad companies advise that vehicles be kept at least

Answer 28

25 feet from the tracks when possible

Question 29

Even when a traffic halt confirmation has been received

Answer 29

Keep the aerial device at least 25 feet above the level of the rails as an added safety (627)

Question 30

To identify signs of structural collapse, an aerial device is a useful tool to obtain an overhead look at the condition of the building

Answer 30

true

Question 31

When dispatch to an aircraft emergency landing

Answer 31

Stage the apparatus near the expected touchdown area.complete the response only after the aircraft has touchdown.

Question 32

At the scene of aircraft incident the apparatus will be primarily used to

Answer 32

Transport firefighters and portable equipment as needed to upper level

Question 33

Aerial apparatus are more likely to be useful at

Answer 33

At non-accident related fires involving large-frame aircraft

Question 34

The driver should always position the Apparatus outside the dike's walls, unless

Answer 34

the roadway is on top of the dike

Question 35

The distance between aerial apparatus and the objective should be consistent with the

Answer 35

Ladder's planned use and the conditions at the emergency scene

Question 36

If the manufacturer recommends that it's device be operated in the support position, the load or the amount of extension for the aerial device must be reduce for

Answer 36

angles of elevation during on supported operations

Question 37

When approaching, positioning, and operating at an incident, driver should place the Apparatus in a position that

Answer 37

Minimize the angle and extension to which aerial device will be raised

Question 38

When an apparatus must operate off an incline, driver can reduce stress by
