What is the proper sequence of aerial operation?

• A. Elevate, Rotate, Extend, Lower
• B. Elevate, Extend, Rotate, Lower
• C. Rotate, Elevate, Extend, Lower
• D. Extend, Elevate, Rotate, Lower

Answer: (A)

Elevate the aerial first to a safe working height, then rotate to face the target, extend to reach the distance you need, and finally lower the ladder after the task is complete. Elevating first establishes a stable base and gives you full control of the platform height before you begin moving laterally or reaching out. Rotating at that height keeps the center of gravity over the vehicle while you aim, reducing the chance of instability or collision as you change direction. Extending comes after you’re oriented, so you can accurately reach the target without chasing a moving or misaligned position. Lowering is last, returning the apparatus to a safe, stowed condition after work is done. Extending before rotating or rotating before elevating can lead to awkward reach, obstacles, or balance issues, making the operation less safe and efficient.
