Multi-Piece and Single-Piece Rim Wheels - Hazards |
||||||
|
Single-piece
rim wheels react differently than multi-piece
rim wheels in accidents involving a release of pressurized air. In a multi-piece rim wheel accident, the wheel components separate and are released from the rim wheel with violent force. The severity of the hazard is related not only to the air pressure but also to the air volume. Single-piece rim wheel accidents occur when the pressurized air contained in the tire is released suddenly by a bead breaking or the bead slipping over the rim flange. An employee in close proximity and within the rim wheel trajectory can be hurled across the room. A release of pressurized air can also propel the rim wheel in any potential path that a rim wheel component may travel during an explosive separation, or the area into which the airblast may be released. All employees working with rim wheels require training for these hazards. |
