Q

When an apparatus must operate off an incline

A

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

18
Q

When approaching from the uphill side, the Apparatus

A

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

19
Q

When approaching from the downhill side the Apparatus should be

A

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

20
Q

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

A

true

21
Q

The maximum loading for any unsupported aerial device occurs when operated at angles between

A

70° and 80° from horizontal

22
Q

As extension increases,aerial loading must_____

A

decrease

23
Q

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

A

weakest operational position

24
Q

Most modern aerial devices are designed to be operated

A

In the unsupported position

25
Q

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

A

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

26
Q

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

A

Highway, interstate, turnpikes, and other busy roadways

27
Q

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

A

150-200 feet

28
Q

Most railroad companies advise that vehicles be kept at least

A

25 feet from the tracks when possible

29
Q

Even when a traffic halt confirmation has been received

A

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

30
Q

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

A

true

31
Q

When dispatch to an aircraft emergency landing

A

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

32
Q

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

A

Transport firefighters and portable equipment as needed to upper level

33
Q

Aerial apparatus are more likely to be useful at

A

At non-accident related fires involving large-frame aircraft

34
Q

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

A

the roadway is on top of the dike

35
Q

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

A

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

36
Q

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

A

angles of elevation during on supported operations

37
Q

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

A

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

38
Q

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

A

Spotting the turntable downhill from the point of operation

39
Q

For any given situation, the proper distance between the objective and aerial apparatus is

A

the distance that afford the maximum stability,the best climbing angle,and adequate extension

40
