Q

How do you jump from an energized vehicle

A

Jump clear from it and try to land on both feet falling forward

20
Q

Apparatus is most stable when the aerial device is operated directly over

A

The front or back of the vehicle

21
Q

The greatest stability and a tiller occurs when it is jackknifed approximately how many degrees

A

60°

22
Q

Good tiller stability occurs when it is jackknifed up to how many degrees

A

60-90°

23
Q

Beyond what degrees does stability decreasing rapidly when jackknifing a tiller

A

Beyond 90°

24
Q

Stress tends to be greater when the aerial device is in

A

Motion

25
Q

Stress in the aerial device is increased when the ladder rungs are operated perpendicular to the ground or when the apparatus is parked

A

On an incline and the device must operate off the side of the apparatus. Creating torsion of the ladder

26
Q

When approaching from the uphill side the apparatus should position how

A

Drive past fire building with aerial device operating over rear of truck

27
Q

When approaching from the downhill side the apparatus should be positioned how

A

Stop short of the building with aerial device operating over front of truck. Optimal position

28
Q

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

A

70 and 80° from horizontal

29
Q

True false the apparatus should be shut down if it is solely used for providing additional support personnel

A

True

30
Q

If water is not available above grade or on an overpass how can water be brought to the scene

A

Ladder attaches to hydrant below grade or on the street below overpass stretch line up aerial

31
Q

Apparatus should be positioned at an angle so that the operator side is

A

Protected from traffic

32
Q

The front wheel should be turned away from firefighters working on Highway incidents so that

A

If struck from behind it will not be pushed into them

33
Q

True false close at least one lane next to the incident lane on highways

A

True

34
Q

A second apparatus should be considered for parking behind the initial barrier to act as an additional. How far away

A

150-200 feet

35
Q

At night a minimum number of warning lights should be used to prevent

A

Blinding or distracting other drivers

36
Q

Most Railway Co. is advise the vehicles be capped at least how far from the tracks whenever possible

A

At least 25 feet

37
Q

Aerial device it should be positioned where in regards to railway lines

A

Same side as incident

38
Q

If an aerial device needs to be parked on the opposite side of the incident across railroad tracks what should be done

A

Make sure rail away traffic has been halted. Keep device at least 25 feet above level of tracks as safety precaution

39
Q

If possible during a medical where should apparatus be parked

A

Off the street

40
Q

True false residential driveways and the yards are recommended as stable services for parking apparatus

A

Faults

41
Q

Buildings that have been subjected to extensive fire damage or buildings in poor condition before the incident may be subject to

A

Falling debris or collapse

42
Q

The collapse on is equal to how many times the building height

A

1.5 times

43
Q

Indicators for unstable buildings and potential collapse hazard

A 
Bulging wall
. Sagging roof
. Large cracks in exterior
 Falling bricks. 
Internal collapse
44
Q

During hazmat incident to not park over manholes or storm drains because

A

Flammable liquid may flow underground it to system ignite and explode

45
Q

Many aircraft accidents occur away from

A

Paved surfaces

46
Q

When operating at storage tank fires apparatus should never be placed or spotted inside

A

Inside of the dike that surrounds the tank

47
Q

Went to aerials responded to a given location the first arriving aerial takes the front of the building and the second goes to

A

The rear or side depending on access
