Abstract: At approximately 10:30 a.m. on March 5, 1996, Employee #1 was welding rebar for a bridge earthquake retro-fit project. He unhooked his safety belt lanyard in preparation for moving to a higher level when the two 2 by 12 by 6 planks on which he was standing dislodged. Employee #1 fell approximately 14 ft to dirt at the base of a bridge column, sustaining a fractured right collarbone and lower back injuries. Coworkers contacted 911 and administered first aid until paramedics arrived and transported Employee #1 to a local hospital. The plank platform was not secured to the ledge, and the planks slid off when he attempted to climb higher.
