Abstract
A warning system for an aerial device which provides an alarm signal when a worker on an aerial work platform is exposed to an electrical hazard. The aerial device has an insulated boom which carries the work platform on its upper end. An electrostatic charge is introduced to all conductive components near the platform. The electrostatic charge is harmless to the worker and dissipates upon contact with an energized power line or grounded object. The absence of charge is then sensed by a warning device which provides an alarm signal.
