What is a typical sequence for deploying an aerial during an interior rescue operation?

• A. Randomly extend booms without stabilization.
• B. Extend booms first, then stabilize.
• C. Stabilize, extend to projected height, position for access, extend booms, and carefully assist occupants while maintaining stability.
• D. Engage in interior rescue before stabilizing.

Answer: (C)

Stability and a planned sequence are the foundation of safe aerial deployment in an interior rescue. Before anything else, the vehicle must be stabilized and leveled with outriggers properly deployed so the apparatus won’t shift when the ladder is extended or when occupants and equipment move.

With the rig solid, extend the aerial to the projected height needed for the rescue. This keeps the ladder within its safe operating range and ensures you aren’t reaching beyond what the apparatus can safely handle. Next, position the ladder for access—line it up with the safest entry or exit point, and set the angle so occupants can reach the ladder without overreaching or losing footing. Once the ladder is properly supported and aimed, extend the booms to bring the tip to the appropriate height and reach for interior access. Finally, carefully assist occupants while maintaining the stability of the platform, continuing to monitor balance and preserving control of the aerial throughout the rescue.

Extending booms or attempting interior rescue without first stabilizing creates a tipping or shifting risk. Extending booms without stabilization can overload one side of the vehicle, and starting interior rescue before stabilizing can put occupants and firefighters in danger due to unexpected movement.
