Abstract: TWO EMPLOYEES WERE UNLOADING LIQUID PETROLEUM GAS TANKS FROM THE BED OF A BOOM TRUCK. THE BOOM CONTACTED A 7200-VOLT OVERHEAD POWER LINE. THE BOOM OPERATOR JUMPED FROM THE TRUCK WHEN CONTACT WAS MADE. HOWEVER, HE THEN TURNED TOWARD THE TRUCK, CONTACTED IT, AND WAS ELECTROCUTED. HIS COWORKER TRIED TO MOVE THE BOOM AWAY FROM THE LINES BY USING A HOSE WITH A METAL CORE TO REACH THE CONTROLS. HE WAS ELECTROCUTED WHEN THE HOSE TOUCHED THE CONTROLS. TWO OTHER EMPLOYEES IN THE AREA RECEIVED ELECTRIC SHOCKS FROM THE GROUND POTENTIAL GRADIENT AROUND THE TRUCK. THESE TWO EMPLOYEES WERE TREATED AT A HOSPITAL AND RELEASED AFTER RECEIVING ELECTRO-CARDIOGRAMS.
