## Narrative

The welder was working on a new conveyor when he stepped on a three foot piece of 1 ? inch angle. The piece of angle tipped down which caused his left knee to flex quickly resulting in a torn meniscus. On January 3, 2005, he had surgery to repair his meniscus. The injured is on layoff and has not missed any scheduled work at this time.
