METAL/NONMETAL MINE FATALITY - On April 22, 1998, a 39-year old maintenance worker with 8 years of mining experience was killed and two coworkers seriously injured at a limestone operation. A scraper tire was placed flat on the ground and they were attempting to remove the brake drum from the rim. The tire was not deflated and they had used an oxygen/acetylene torch to cut the brake drum when the tire exploded.
Never apply a heat source to a tire rim/hub until the tire is removed from the rim/hub assembly. The manufacturer's guidelines for tire and brake drum 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.
