Machine operator fatally injured when struck by the elevator of a concrete block cuber machine - Tennessee, August 29, 1995.
Morgantown, WV: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, FACE 95-14, 1995 Oct; :1-7
A 22 year old male machine operator who worked at a concrete block manufacturing facility died after being struck by the elevator of a concrete block cuber machine. The facility had nine workers on one shift; there was no safety manager, safety policy or written safety procedures. The victim was operating the metal stripping machine which placed metal bands around cubes of blocks, 90 blocks to a cube. The accident was not observed, but the victim apparently noted that a cube of blocks was lodged on the conveyor belt near the cuber machine. Although procedure required that the cuber machine be shut down and locked out before accessing the working area of the machine, the victim apparently opened a manually operated steel access gate into the machine's operating area while the machine was operating, entered the area and attempted to correct the positioning of the cube of blocks. The cuber machine cycled and the elevator dropped, striking the victim on the lower spine, and trapping him. He was pronounced dead on arrival at the hospital due to crushing lower trunk injuries. Recommendations include the development, implementation, and enforcement of a written safety procedure including task specific training and lockout procedures, that consideration be given to the development and installation of interlocking gates which protect workers, and that a safety hazard analysis be conducted of all work areas.
