Case Study: In May 2004, a mechanical engineering technician in Richmond, California, was assigned to install new access doors on an automatic storage and refrigeration unit. Before he worked on the unit, he neglected to lockout/tagout the unit. As he was working, a laboratory support specialist operated the equipment without the knowledge that the technician was installing rear access doors. The technician lost consciousness after being crushed between the automatic storage and refrigeration systems. He sustained a punctured blood vessel in the eye and a crushed chest. He was treated on the scene by emergency medical personnel and was hospitalized for two days.
In December 2008, a construction worker in San Jose, California, accidentally dropped an empty paper sack into a grout mixer. He failed to de-energize the machine to retrieve the sack. Two of his fingers were severed at the tips by the rotating blades and he was hospitalized.
Key Takeaways: OSHA estimates that compliance with the lockout/tagout (LOTO) standard prevents an estimated 120 fatalities and 50,000 injuries each year. Do your part! Always follow employer-designated LOTO procedures for the control of hazardous energy.
