METAL/NONMETAL MINE FATALITY - On February 17, 1999, a 35-year-old technician (contractor operator) with 10 years experience was fatally injured at a sand and gravel operation. The victim used a fork lift attached to a chain while attempting to remove a wheel assembly from a dump trailer in preparation to repair the brakes. After these attempts failed to free the wheel, he applied heat to the back side of the wheel with an oxygen/acetylene torch and the tire ruptured.
Never apply a heat source to a tire rim/hub until the tire has been removed from the rim/hub assembly.
The manufacturer's guidelines for wheel removal should be consulted and followed.
Tire and rim safety training should be provided to maintenance personnel who are required to service tires and rims.
