Aerial 8

Question 1

A driver operator is fundamentally a ($$$$$$) who must be well trained in the location of each control, its function, how it operates, when it should be used, and the appropriate safety functions.

Answer 1

Technician

Question 2

($$$$$$) means elevating the entire assembly from its stored position to a desired angle and useful position.

Answer 2

Raising the aerial.

Question 3

The aerial device should be positioned approximately ($$$$) above the surface and allowed to settle onto the surface from the weight of the fire fighters on the device.

Answer 3

4 to 6 inches

Question 4

Most aerial failures or apparatus overturning accidents involve a combination of overloading and overextension of the ladder at ($$$) angles of elevation.

Answer 4

Low

Question 5

Several documented aerial ladder failures can also be traced to situations where a ladder pipe had been in operation with the aerial ladder placed at a low angle of elevation. The failures occurred shortly after the water supply of the ladder was ($$$$$).

Answer 5

Shut off

Question 6

Most aerial device manufactures specify wind speed limitations within which the aerial device may be safely operated. Theses li it actions will vary among manufactures; however, most allow full operations in winds up to ($$$$). Wind speeds beyond ($$$$$) can be vary dangerous;

Answer 6

35 to 40 mph

40 mph

Question 7

The manufacturers of several older, light duty ladders recommend the use of GUY ROPES in winds exceeding ($$$$$). GUY ROPES should be attached to the fly section when it is necessary to extend the ladder ($$$$$) or more.

Answer 7

35 mph

75 feet

Question 8

Tension should be maintained on the GUY ROPE in the direction ($$$$$$$$), especially if the wind is blowing side ways against the ladder.

Answer 8

Form which the wind is coming

Question 9

Wind speed 15 -24mph .

Answer 9

Small trees in motion; whitecaps visible on small ponds and lakes

Question 10

Wind speed 25-31 mph.

Answer 10

Large tree branches in motion; whistling herd in utility wires.

Question 11

Wind speed 32-38 mph

Answer 11

Whole trees in motion; inconvenience felt walking against the wind.

Question 12

Wind speed 39-54 mph

Answer 12

Twigs breaking off trees; walking against the wind is generally impeded; minor damage to buildings

Question 13

($$$$$$). Loads that are steady, motionless, constant, or applied gradually.

Answer 13

Static load

Question 14

($$$$$). Loads that involve motion. They include the forces arising from wind, moving vehicles, earthquakes, vibration, falling objects. Also called DYNAMIC LOAD.

Answer 14

Shock load

Question 15

All ladders are stronger when the load is applied ($$$$$) to the rungs

Answer 15

Perpendicular

Question 16

If the apparatus is an aerial platform it is important not to exceed the rated weight capacity of the platform. The rated capacity of the platform is the safe carrying capacity in ($$$$) position. Depending upon elevation and extension , additional loads may be safely carried.

Answer 16
