The hazard
A pinch point is any spot where part of your body can get caught between a moving part and something solid, or between two moving parts. They are everywhere on the job: gears, rollers, belts, doors, tailgates, chains, loads being set down and machines that swing. It happens in a split second, and a caught hand can be crushed before you can pull it back.
The action
On construction sites, where a crane's rotating superstructure could strike a worker or pinch a worker against something, the hazard area must be marked with barriers such as warning lines or railings, or with warning signs and markings where barriers are not feasible. Never cut between a swinging machine and a wall, truck or another machine. Before you go into the hazard area out of the operator's view, make sure the operator knows you are going there (29 CFR 1926.1424(a)(3)(i)). (29 CFR 1926.1424(a)(2)(ii))
