Caught in/between accidents occur when workers are crushed or compressed between two or more objects. Injuries that may result include asphyxiation, broken ribs, and other broken bones and bruises. The three primary caught in/between accidents are trench cave-ins, machinery components or vehicles that can trap and compress a worker, such as the back of a garbage truck or a forklift, machinery that can grab or pull a worker. Caught in/between accidents may be caused by collapsing structures as well.n
