Machinery with Unguarded Moving Parts
Almost all sites use machinery that has moving or rotating parts or that requires maintenance or repair at some point during construction.
Machine Guard Safety
If machinery is not properly guarded or de-energized during maintenance or repair, injuries from caught-in or -between hazards may result, ranging from amputations and fractures to death.
When power tools are not properly guarded, workers can get their clothing, gloves, or parts of their body caught in the rotating parts of the tools. If machines are not de-energized (locked-out) when they are being repaired, they may cycle or otherwise start up and catch a worker's body part or clothing and cause injury or death.
Workers can be trapped and crushed under heavy equipment that tips, especially if they are thrown from the equipment.
