Two employees were adding wire pull boxes to two empty conduits. Employee 1 loosened a coupling on a conduit and opened it to check if it was empty. Wires were visible, so the employee went to close the conduit again. Wires in the conduit became pinched and a wire's insulated jacket was damaged. Electricity in the wire (277 volts), grounded out through employee 1 and he was unable to let go of the conduit. Employee 2 pulled employee 1 away and was also shocked. Both employees were hospitalized for electrical shock.
