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.
