Cookeville, TN – Police report that a loose valve cap has caused the death of an employee at M&E Industries.
A valve cap on a highly pressurized tank came loose and hit M&E Industries employee Dewey Mayberry in the chest, critically injuring him. Mayberry was taken to a local medical center where he was pronounced dead.
Dewey Mayberry, age 65, had worked at the M&E Industries plant since 2003. He is reported to have been performing his typical daily job duties when the accident occurred. Local police describe the valve cap as being thick metal and estimate it to have been the size of a “salad plate…about six inches in diameter.”
The M&E Industries facility in Cookeville produces refueling equipment such as filters, filter housings, and filter separators.
Surgoinsville, TN – Five serious workplace safety violations have been documented at MIS Industries in an investigation following a February 12 lockout/tagout accident that killed 34-year-old Arthur James Hendrickson. Hendrickson was crushed while retrieving a part that had jammed a hangar blaster machine at the Tennessee metal finishing facility.
Local officials say that Hendrickson climbed into the hangar blaster to remove a part that had gotten lodged in the equipment. Once he removed the piece, the door closed and Hendrickson was trapped. He was pronounced dead at the scene.
In the course of the investigation, TOSHA (Tennessee Occupational Safety and Health Administration) discovered that neither of the MIS team leaders could recall receiving training on Lockout/Tagout (LOTO) and were ignorant of any of the energy control procedures.
The TOSHA investigator concluded that team leaders on duty initiated maintenance activities on the Hangar Blaster without ensuring that the machine was de-energized to prevent unexpected startup. Lockout/Tagout is sometimes referred to as Hazardous Energy Control (or the Control of Hazardous Energy) – these terms refer to the same standard of preventing unexpected start up or movement of equipment.
It is estimated that 3 million workers service equipment and these employees face the greatest risk of injury if Lockout/Tagout is not properly implemented. Compliance with the lockout/tagout standard prevents an estimated 120 fatalities and 50,000 injuries each year. Workers injured on the job from exposure to hazardous energy lose an average of 24 workdays for recuperation. In a study conducted by the United Auto Workers (UAW), 20% of the fatalities that occurred among their members were attributed to inadequate lockout/tagout and hazardous energy control procedures.
TOSHA concluded that MIS did not make use of its energy control program, did not effectively train employees on their role in Lockout/Tagout, and also neglected to conduct periodic evaluations of their LOTO program.
The five serious violations were: employees were exposed to a caught-in hazard as they failed to apply energy control measures to the Hangar Blaster machine; written lockout procedures failed to clearly and specifically outline the steps for safely shutting down, isolating and securing machinery and equipment to control hazardous energy; MIS failed to conduct annual inspection of their lockout procedures; employees were not instructed in the purpose and use of lockout procedures; and machine guarding were found to be insufficient to protect the operator and other employees in the machine area from hazards.
