A utility line construction crew was in the process of replacing a wooden utility pole with a new metal utility pole and metal cross arm. After the new metal pole and cross arm was installed the crew wrapped an insulated blanket around the pole above the cross arm. Insulators were installed on the cross arm. A crew member was in a lift bucket and was using metal quick ties to connect the power lines to the cross arm insulators. The crew member tied one of the quick ties to an insulator and was preparing to tie one of the power lines to the insulator. The free end of the quick tie slipped out of the crew member's hand and curled underneath the insulated blanket contacting the power line. The power line arced and burned the crew member's face.
