On January 19, 2001, a 29-year old male died from injuries sustained when he was struck on the head by a cycling single-side gantry robot. The victim had recently performed a mold change on a 1500-ton horizontal injection-molding machine (HIMM). He was apparently looking for tools that he may have left within the machine during the set-up operation. The victim climbed on top of the purge guard and leaned over the top of the stationary platen of the HIMM in an attempt to see if the tools were left within the mold area, and placed his head beneath the robot's gantry frame. His position placed him between the robot's home position and the robot's support frame on the stationary platen. While trying to look inside the mold area, the robot cycled, and the victim's head was struck from the side and crushed between the robot and the robot's support frame. Another employee noticed the victim on top of the HIMM and went to investigate. Upon seeing the victim's condition, fellow employees were called to move the victim to the floor. Emergency responders were called, and awaiting emergency responder arrival, employees began chest compressions and other first aid procedures. The victim was pronounced dead on arrival at the local hospital. Recommendations: 1. The robot and the point of operation should be safeguarded to prevent entry during automatic operation. 2. Users should conduct a risk assessment of the robot/robot system to identify equipment, installation, standards, and process hazards so adequate employee safeguards are provided. 3. Users should ensure that personnel who interact with the robot or robot system, such as programmers, teachers, operators and maintenance personnel are trained on the safety issues associated with the task, robot and robot system.
