Abstract
A 23-year-old male operator (victim) of a rotary injection molding machine was crushed by the machine he was operating. This press, known as the DESMA II, consists of six separate molds or stations. Every 32 seconds the press rotates a station to the molten rubber injection port. The mold is then filled with the rubber product and cycles to the next station. Just before the station rotates to the injection port, the operator releases and removes the rubber product from the mold and places it to the side to cool. After the part has cooled sufficiently, the operator trims excess rubber product from the part and places it on a conveyor belt, which moves the part to another process. The molding press is secured to the concrete floor of the facility, and an operating platform is built around one side of the machine. The operator works from the platform, removing the rubber parts from the mold and placing them on the conveyor. There is an open section of the platform where the round press intersects the square platform. This area is termed "no man's land" by the workers (see Diagram 1). The victim may have dropped a tool or a part down to the concrete floor and was lying on his stomach reaching down under the machine when the machine rotated to the next station. The machine caught the victim at the head and neck causing instantaneous death. The MO FACE Investigator concluded that, in order to prevent similar occurrences, ALL employers should incorporate the following recommendations into their safety and health plans: 1. provide machine guarding to prevent machine operators from entering any zone identified as hazardous or from having any part of the body in such a zone during operation of the machinery; 2. develop, implement and enforce a comprehensive safety program that includes, but is not limited to, training of employees in hazard recognition and avoidance, and safe work practices.
