A worker in the meat department of a grocery store was injured while processing meat using a meat mixer/grinder machine. The worker opened the lid/guard of the machine while it was still running and reached inside. The worker’s arm became entangled with the moving parts.
Access to moving parts such as mixing arms, worms and other grinding accessories have caused crushing, laceration and fracture injuries. A guard or other device that prevents access to a moving part that may endanger a worker is required under the Industrial Establishments Regulation (Reg. 851).
Hazard locations include bakeries, grocery stores, restaurants, cafeterias, supermarkets, hotels, theme parks, colleges, schools and the food processing industry.
