Chapter 17

Question 1

For sufficient and safe fire control the driver/operator should?

Answer 1

Must work together with other driver operators to ensure that the aerial apparatus are positioned for maximum use and minimum stress to the aerial devices

Question 2

Placement of aerial apparatus must consider many things including?

Answer 2

Aerial objective, placement of the turntable, scene conditions, and proper stabilization

Question 3

The 5 story rule will only work in areas that?

Answer 3

Have sufficiently wide streets and that are not set too far back from the street

Question 4

The 5 story procedure assumes that the department is operating aerial devices with a reach of?

Answer 4

100 ft this may have to be adjusted for fire departments that operate aerials with reaches of less or greater than 100 ft

Question 5

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

Answer 5

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

Question 6

What places the maximum amount of stress on an aerial device and, in some cases, reduces its load carrying capacity?

Answer 6

Long extensions at low angles

Question 7

It is not advisable to park within the buildings collapse zone if?

Answer 7

The building has been exposed to severe fire conditions or has otherwise been weakened

Question 8

Spotting refers to?

Answer 8

Positioning the apparatus in a location that provides the utmost efficiency for operating on the fireground

Question 9

What are some factors the driver/operator must consider for determining the final operating position of the aerial apparatus?

Answer 9

Surface conditions, grade, windy conditions, electrical hazards and ground or overhead obstructions, angle and location of aerial operation, special situations

Question 10

Apparatus can be parked on soft surfaces in what situations?

Answer 10

Only as a last alternative

Question 11

What is a good indicator of underground voids?

Answer 11

Manhole covers

Question 12

If operators are unsure if the surface can withstand the use of aerial apparatus the driver/operator should?

Answer 12

Err on the side of caution

Question 13

What is a primary spotting consideration with hot weather?

Answer 13

Extreme heat may tend to weaken marginal or otherwise firm paved surfaces

Question 14

What is one visual indicator of a compromised asphalt surface due to extreme heat?

Answer 14

The asphalt “bleeds” creating a shiny, glass-like surface

Question 15

What must the driver/operator consider when positioning with the front of the apparatus up hill?

Answer 15

With the rear tires off the ground, the truck has less resistance to sliding downhill. But the rear compartments will be more difficult to reach once the apparatus is leveled

Question 16

What must the driver/operator consider when positioning with the rear of the apparatus up hill?

Answer 16

It will be easier to reach the ground with a platform operating off the rear of the apparatus. But it will be more likely that the front tires will be lifted off the ground causing the frame rails to sag and making the device more difficult to stow properly after operations are complete

Question 17

Depending on operational capabilities of apparatus and severity of grade,apparatus with two rear jacks may have to face uphill because?

Answer 17

Facing uphill, the angle of the turntable is decreased thereby increasing capability and stability. If the apparatus was facing downhill the capability of the apparatus may be decreased

Question 18

When it is necessary to operate in high wind conditions, the driver/operator should spot the apparatus in a manner that?

Answer 18

Minimizes the extension needed

Question 19

The long standing fire service standard has been to provide how many feet of clearance between the aerial device and overhead high voltage lines energized from 600-50,000 volts?

Answer 19

10 feet

Question 20

The long standing fire service standard has been to provide at least how many feet for high voltage transmission lines over 50,000 volts?

Answer 20

50 feet

Question 21

What distance does OSHAs new standard say there should be between the device and overhead electrical lines less than 350 kilovolts?

Answer 21

20 ft

Question 22

What distance does OSHAs new standard say should be between the device and high tension lines over 350 kilovolts?

Answer 22

OSHA requires 50 ft of clearance

Question 23

Stability of the aerial apparatus can be improved by?

Answer 23

Operating the aerial device in line with the longitudinal axis (apparatus body) (front to back)

Question 24

The aerial apparatus is most stable when?

Answer 24

The aerial device is operated directly over the front or rear of the vehicle

Question 25

At what angle to the apparatus body is aerial apparatus the least stable?

Answer 25

An angle perpendicular to the apparatus is the least stable position

Question 26

With rear mounted apparatus what is the preferred method of parking?

Answer 26

Backing in apparatus is the preferred method, as this maximizes the reach of the aerial device, as opposed to nosing in the apparatus, which would shorten the possible reach by a distance equal to the length of the apparatus.

Question 27

Stress in aerial devices is increased when?

Answer 27

The ladder rungs are operated nonparallel to the ground or when the apparatus is parked on an incline and the aerial device must be operated off the side of the apparatus.

Question 28

When the apparatus must operate off an incline, the driver/operator can reduce these stresses by?

Answer 28

Spotting the turntable downhill from the point of operation

Question 29

The maximum loading for any unsupported aerial device occurs when?

Answer 29

Operated at angles between 70-80 degrees from horizontal

Question 30

Aerials are at their weakest operational position when?

Answer 30

Low angle of elevation and at long extension

Question 31

On high speed roadways, apparatus should not be driven against the normal flow of traffic unless?

Answer 31

The road has been cleared by law enforcement for that purpose?

Question 32

Most railroad companies advise that vehicles be kept at least how many feet away from the tracks if possible ?

Answer 32

25 feet

Question 33

If it becomes absolutely necessary to raise an aerial device across a railroad track, the aerial device should be kept at least how many feet above the levels of the rails as an added safety precaution?

Answer 33

At least 25 ft

Question 34

If it is not possible to locate off the street the driver/operator should position the apparatus?

Answer 34

To shield firefighters from traffic
