A 52-year-old Hispanic supervisor died when he was crushed in a machine used in manufacturing concrete blocks. Evidence suggests that the victim had climbed on top of the machine, possibly to reconnect an air line. The victim did not shut the machine down and lock and tag it out prior to climbing on top of it. The skip hoist had dumped product into the hopper portion of the machine and was on its down cycle when the incident occurred. There were no guards in place to prevent the victim from climbing on the machine while it was running. The CA/FACE investigator determined that, in order to prevent future occurrences, employers, as part of their Injury and Illness Prevention Program (IIPP), should: 1. Ensure employees follow the proper lockout/tagout procedures on machinery before performing any repair, maintenance, connection, or adjustments. 2. Ensure employee safety by installing guards around the moving parts and pinch points of the machine to protect employees from accidental contact. In addition, manufacturers should design and employers should retrofit machinery so that a worker can remotely turn parts of a machine on or off while the machine is operating.
