On June 1, 2005, a 37-year-old male machinist was fatally injured when he became caught in the vertical milling machine he was operating at an aerospace parts manufacturer. The victim had reached into the cabinet of the milling machine when the machine cycled, crushing him. A co-worker (co-worker #1) had walked by the machine to let the victim know that it was break time when he noticed that the victim was caught inside the machine. Co-worker #1 had another co-worker (co-worker #2) place a call for emergency medical services (EMS). Multiple co-workers worked to free the victim prior to EMS arriving. EMS transported the victim from the incident location to a local hospital where he was pronounced dead. The Massachusetts FACE Program concluded that to prevent similar occurrences in the future, employers should: 1. Ensure that existing and newly purchased machining centers with cabinet doors are equipped with interlocks; 2. Develop, implement, and enforce a comprehensive hazardous energy control program including a lockout/tagout procedure and training; 3. Provide employees training, in the employees' primary language(s) and at appropriate literacy levels, on machines they will use, worksite hazards and controls for these hazards; 4. Provide frequent supervision of newly-hired and inexperienced employees; 5. Periodically perform equipment hazard analyses to ensure equipment is safe to operate; 6. Develop, implement, and enforce a comprehensive written health and safety program. In addition, machining center manufacturers should: 7. Ensure that all moveable guards of new numerically controlled and automatic milling machines are safeguarded with interlocks.
