Aerial Lift Definitions

Aerial lift (device): Any vehicle-mounted device, telescoping or articulating, or both, which is used to position personnel, including extensible boom platforms, aerial ladders, articulating boom platforms, or vertical towers.

Anchor point: A secure point of attachment for lifelines, lanyards, or deceleration devices.

Articulating boom platform:  An aerial device with two or more hinged boom sections. 

Connecting device: A flexible line used to secure a body harness to a lifeline or directly to a point of anchorage.

Fall arrest: A system used to stop a fall from heights and decrease the impact of forces on a body to minimize the extent of injury. It consists of an anchor point, connecting device, and full body harness.

Fall restraint: Equipment used to keep a person from reaching a fall point, such as the edge of a roof.

Insulated boom: The boom is separated from other conducting surfaces by a dielectric substance (including air space) offering a high resistance to the passage of current. 

Maximum capacity or maximum intended load: The total load of all employees, tools, materials, and other loads reasonably anticipated to be applied to a personnel platform at any one time.   

Outriggers: A device used to increase the stability of the lift.
