When lowering an aerial device, how far above the surface of the object should it be positioned?

Positioning the aerial device 4-6 inches above the surface of the object is essential for ensuring a smooth and controlled lowering process. This distance allows for a safe margin that mitigates the risk of striking the object as the aerial device descends. It also provides enough clearance to avoid potential obstructions or uneven surfaces that could cause instability or damage to the equipment.

Having this vertical space allows the personnel operating the aerial device to make adjustments if necessary, such as correcting for any slight movements or changes in positioning without the risk of making contact with the object below. This practice is also rooted in standard operating procedures that prioritize safety and efficiency in aerial operations, ensuring that both the crew and the equipment remain secure during the maneuver.
