Owner of heavy equipment maintenance business dies after being struck by an exploding split rim of a test roller tire.

NIOSH 1992 Sep; :1-4
A 32-year-old male owner of a heavy equipment maintenance business (victim) died as a result of injuries he received when the split rim of a test roller's tire exploded as he attempted to remove the wheel. He was struck by the exploding unit and thrown approximately 45 feet. He had no training or experience with this type of split rim tire and used no protective equipment except for ear muffs during the procedure. The repairman was subcontracted to repair a wheel of the test roller which was rubbing against the concrete weights. It was necessary to remove the wheel and tire from the axle to facilitate repair. The victim removed inappropriate bolts on the split rim which resulted in the unintentional dismantling of it, when he apparently only intended to remove hub nuts to remove the wheel. MN FACE investigators concluded that, in order to prevent similar occurrences, the following guidelines should be followed: 1. manufacturer instructions and warnings should be consulted prior to removing split rim tires to ensure that proper nuts and bolts are removed to avoid unintentional dismantling; 2. only personnel familiar with and trained in controlling the hazards of split rim-mounted tires should attempt to remove them from equipment; and 3. split rim and axle bolts on wheels should be incompatible so split rims are identified from axles and require two different tools to remove the different bolts.
