Abstract: At approximately 2:30 a.m. on October 29, 2012, Employee #1, employed as a laborer by a construction company, was performing excavation work at Los Angeles International Airport. He had been working there for a few months, with duties that included removing a metal plate to expose a trench beneath. He was performing this regularly assigned task, using an excavator to move the metal plates, and in close proximity to Coworkers #1 and #2. The plate was rigged with a sling and attached with a hook. Employee #1 was guiding the plate with his hand. The sling slipped out of the hook, whereupon the plate fell and landed on Employee #1's hand. He was transported to UCLA Ronald Reagan Hospital, where he was hospitalized and treated for a crushed hand. The employer's Safety Director notified the Cal/OSHA Division on October 29, 2012. The investigation, which began November 6, 2012, included interviews with Employee #1 and Coworkers #1 and #2. The investigation concluded that there was a violation for not keeping employees clear of loads about to be lifted and suspended loads. The employer also used a hook that was not designed to work with the type of sling that was used to lift the plate. The Division issued a serious accident related citation for T8CCR 1593(n).
