3. Which factor most directly affects aerial device stability?
A. Water pressure
B. Number of personnel on the ladder
C. Wind direction
D. Positioning and use of stabilizers
Proper use and positioning of stabilizers ensure the apparatus remains
steady during aerial operations.
4. When operating on a slope, aerial apparatus should be positioned:
