An employee was trying to line up the back and front rollers of a jammed conveyor when his left ring finger was partially amputated between the sprocket and drive chain.
An employee was terminating cables in a junction box. A loose ground wire came into contact with the bushing, causing a flash that burned the right side of the employee's face and his right hand.
An employee was using a bucket truck hoist to raise secondary aerial wiring. The wire made contact with the primary wire, causing an arc flash. The employee suffered burns to both hands and was hospitalized.
A temporary employee was testing an electrical starter motor. He was placing tape on the starter while the breaker was not engaged, but the starter sent an arc flash that burned his hands and stomach.
Two employees were removing a circuit breaker. The injured employee was using wrenches in the removal process. One of the wrenches contacted an adjacent door, resulting in an arc flash. The employee suffered burns to their neck, face, and ear, as well as momentary vision loss due to the flash.
