Types of Caught-In or Caught-Between Hazards

Working conditions that contribute to caught-in or caught-between hazards include the following:

• Machinery that has unguarded moving parts or that is not locked out during maintenance
• Unprotected excavations and trenches
• Heavy equipment that tips over, collapsing walls during demolition
• Working between moving materials and immovable structures, vehicles, or equipment

Unguarded Moving Parts and Machinery That Is Not Locked Out

Most workers on construction sites use machinery that has moving or rotating parts or that requires maintenance or repair. When machines or power tools are not properly guarded, workers can get clothing or body parts caught in the machines.

If machines are not de-energized (locked-out) when they are being repaired, they may cycle or otherwise start up, 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 the worker is thrown from the equipment.
