An employee was working in an aerial lift with a material handler jib and winch line on it. He was in the bucket at the top of the pole, installing a pulling dolly, placing the conductor in the dolly, and preparing it to be tied off under tension. The employee needed a second line grip, so he used the winch jib line to retrieve the tool from the top of the pole. The line jammed in the reel of the jib winch and the employee pulled the line free. This caused his hand to become caught and get pulled into the winch. He sustained several fractures to the middle, ring, and little fingers of the left hand as well as avulsions to the middle and ring fingers.
