title: Fatal and nonfatal occupational injuries involving wood chippers--United States, 1992-2002.
abstract: Tree damage from storms and routine tree-trimming operations prompt the need for disposing of branches and brush. Mobile wood chippers shred branches and tree trimmings into mulch. Branches are fed into a chute, in which rotating blades macerate the wood. Mobile chippers pose potential dangers to operators, who can become caught in the feed mechanism and pulled into the rotating chipper knives or struck by the hood of the machine while it is being opened or closed with the knives still rotating. This report summarizes data describing fatal and nonfatal injuries related to occupational wood chipper use, which indicate that those working with mobile wood chippers are at risk for serious injury and death, but that these injuries can be prevented through proper training, machine maintenance, and the use of personal protective equipment.
