An employee was installing 2x4 light fixtures into a ceiling grid. He measured how much tie wire he would need to secure the fixtures' catty corner onto the ceiling grid. He realized he would need a taller ladder so he started coming down and decided to cut the wire he had measured out. The wire spool was sitting on top of the ladder he was using. When he cut the wire, the end sprang upwards and went between the bottom of his safety glasses and his face, puncturing his right eye.
