What are three key actions to take when turning an aerial apparatus 180 degrees?

When turning an aerial apparatus 180 degrees, using side view mirrors, being aware of obstructions, and ensuring visibility of your spotter are crucial actions to ensure safety and effectiveness. Side view mirrors allow the driver to monitor the surroundings, providing a clear view of any vehicles or obstacles that might be in the way during the turn. Being aware of obstructions is essential to prevent collisions or damage to the apparatus, especially given the size and maneuverability challenges of aerial equipment. Additionally, having good visibility of the spotter is critical; the spotter is often positioned to assist the driver by providing guidance on clearances and hazards that might not be visible from the driver’s seat.

The other choices, while they contain relevant actions, do not specifically address the unique considerations for turning an aerial apparatus. For instance, reducing speed and honking the horn might be helpful in general driving situations to alert others, but they don't specifically address the visibility and spatial awareness required when navigating a large vehicle like an aerial apparatus. Similarly, securing loose equipment, adjusting stabilizers, or activating lights and turn signals are important in their own contexts, but they do not focus on the immediate needs during a turn, such as precautionary checks for obstructions and communication with a spotter
