Before lowering the aerial device into its bed, what must be done?

Before lowering the aerial device into its bed, it is essential to remove personnel from the aerial ladder. This step ensures the safety of all individuals involved, preventing potential accidents or injuries that could occur if personnel are still present while the aerial device is being stowed. The aerial apparatus is designed to operate with heavy equipment in motion, and having people on the ladder poses a significant risk during this process.

While other considerations such as checking gauges, ensuring hoses are packed away, or inspecting the area for hazards are also important for the safe operation and function of the aerial apparatus, the immediate priority when preparing to lower the aerial device is to guarantee that no personnel are on or near the apparatus. This action helps maintain a safe environment during operations, allowing for a smooth and risk-free lowering process.
