Event description
ELECTRIC SHOCK - CONTACT WITH OVERHEAD LINE THRU BOOM
Investigation abstract
A power line worker was working from an aerial lift, attaching a ground wire to a newly positioned utility pole. The boom of the aerial lift was above a 7620-vo lt overhead power line. The employee was using an all-metal pneumatic tool with a standard 6.4-millimeter service-station air hose. He was not wearing rubber in sulating gloves. The insulated boom had a 140-millimeter by 406-millimeter metal supporting plate underneath. The boom contacted the power line. The air hose, w hich had not been tested electrically, was corroded with grease and grit and was not capable of withstanding the voltage imposed on it. Consequently, the power line worker was electrocuted.
