When raising the aerial device, how should the fly sections be extended?

The correct approach when raising the aerial device is to extend the fly sections until the tip is slightly above the target. This practice is crucial for ensuring operational safety and efficiency. By extending the tip of the device just above the intended target, it provides an adequate margin for error when positioning the aerial device for operations such as rescue, firefighting, or maintenance.

This method enables the operator to make fine adjustments based on the specific requirements of the task at hand, such as the height of the structure or the conditions being observed at the scene. It also helps to prevent mishaps that could occur if the tip were to be too low, risking contact with obstacles or compromising the safety of personnel operating the device.

The other options do not provide the best practice for safety and effectiveness. Extending the tip to ground level would pose a risk of collision and limit the functional reach of the device. Fully extending in one motion lacks the necessary precision and control required to safely position the aerial device, which could lead to overshooting or accidents. Limiting the extension to just the first section may not allow sufficient reach for the task and could hinder the effectiveness of the operation.
