After completing snow removal activities for the day, a Teamster backed the sanding truck up to a building to recharge the sanding unit. The individual plugged a fifty foot extension cord into a GFCI rated outlet on the building then ran the cord to the truck. While wearing wet winter gloves, he plugged the 110 volt energized power cord into the outdoor rated sanding unit battery charger when he experienced an electric shock. This could have resulted in personal injury.

Lesson Learned: Eliminate the hazard of plugging in electrical equipment in wet conditions by re-configuring vehicles equipped with auxiliary battery chargers to be charged from the vehicle's electrical system. The battery is charged while the vehicle is in use, thus eliminating the need to charge from an external power source. Warn employees of the dangers of hazardous energy and potential for injury from the practice of connecting electrical equipment with wet hands or gloves.
