Select one:
a. Extend the Inboard stabilizer (working side) first until the stabilizer is fully extended horizontally, and then begin to lower that stabilizer to the ground

A
(App L-7 3.3)
The correct answer is: Extend the Inboard stabilizer (working side) first until the stabilizer is fully extended horizontally, and then begin to lower that stabilizer to the ground
The guideline for extending and lowering stabilizers for aerial ladders when the ground is NOT level is correctly stated in which point?
Select one:
a. Extend the stabilizer on the lowest side first until the stabilizer is fully extended horizontally, then lower that stabilizer to its maximum.
b. Extend the stabilizer on the high side first until the stabilizer is fully extended horizontally, and then lower that stabilizer to its maximum.
A
(App L-7 3.3)
The correct answer is: Extend the stabilizer on the lowest side first until the stabilizer is fully extended horizontally, then lower that stabilizer to its maximum.
The guideline for extending and lowering stabilizers for aerial ladders when the ground is NOT level and the inboard side (working side) is also the high side is to: Extend the stabilizer on the low side first until that stabilizer is fully extended horizontally, then lower that stabilizer to its maximum. Then, ensure the inboard stabilizer is fully extended horizontally, and then lowered the distance necessary to level the apparatus.
Select one:
