b. Fireground runoff

Question 2

When positioning an apparatus with the rear uphill on a grade, which of the following tactical impacts should be considered?

a. It will be more difficult to reach the ground with a platform operating off of the rear.
b. It will be easier to reach the ground with a platform operating off the rear.
c. The rear compartments will be more difficult to reach once the apparatus is leveled.
d. With the rear tires off the ground, the truck has less resistance to sliding downhill.

Answer 2

b. It will be easier to reach the ground with a platform operating off the rear.

Question 3

Generally SOPs involving apparatus placement at a fire scene apply to:

a. later-arriving, supporting aerial apparatus.
b. aerial apparatus assigned to the initial response.
c. all vehicles at a fire scene regardless of arrival time.
d. all aerial apparatus arriving at the fire
scene.

Answer 3

b. aerial apparatus assigned to the initial response.

Question 4

Caution should be exercised around normally harmless overhead wires such as telephone and cable TV lines because:

a. they may become energized at random times.
b. any cables have the potential to cause damage to the apparatus.
c. they may be in contact with electric lines somewhere down the line and be
energized.
d. thunderstorms can temporarily charge these types of lines.

Answer 4

c. they may be in contact with electric lines somewhere down the line and be
energized.

Question 5

When responding to hazardous materials incidents, which of the following is the BEST reason the aerial apparatus should not be parked over manholes or storm drains?

a. Haz mat technicians may need to enter the underground system at certain points of entry.
b. Haz mat technicians may need to monitor the underground system for contamination.
c. Flammable material flowing into the underground system could ignite and explode.
d. The manhole or drainage cover may slip and threaten stability of the apparatus.

Answer 5

c. Flammable material flowing into the underground system could ignite and explode.

Question 6

Which of the following is a factor that works against an aerial device’s strength?

a. Stresses
b. Spotting
c. Jackknifing
d. Grades

Answer 6

a. 90 degrees.
b. 60 degrees.
c. 180 degrees.
d. 120 degrees.

Answer 7

b. 60 degrees.

Question 8

a. be kept at least 25 ft. (7.5 m) above the level of the rails.
b. be kept perpendicular to the other apparatus at the scene.
c. not be raised over the tracks for any reason.
d. be placed in a jackknifed position to improve stability.

Answer 8

a. be kept at least 25 ft. (7.5 m) above the level of the rails.
