Description:A 53-year-old truck driver was killed when a 1,010 pound support arm fell on him. He was in the process of setting up a portable rubble plant which is used for crushing concrete. Part of the setup involves rotating a support leg 90 degrees from the transport position to the stationary position. The support leg pivots from the transport position to the stationary position on a 3-1/2" bolt with a one-inch diameter. The threads on the bolt stripped and the nut fell off allowing the support arm to fall on the victim. The Nebraska Department of Labor investigator concluded that to prevent future similar occurrences: 1. Employers should ensure that procedures are available for setting up and breaking down the portable rubble plant. 2. Employers should ensure a periodic inspection schedule is developed for checking the condition of the portable rubble plant which includes checking the condition of the bolts/nuts and/or pivot device on the support leg. 3. The manufacturer of the portable rubble plant should consider a redesign which would provide a safer pivot point for the support leg.
