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
Machines must have guarding that protects the operator and others nearby from hazards such as the point of operation, ingoing nip points and rotating parts. On construction sites, exposed belts, gears, pulleys, chains and other moving parts of equipment must be guarded too (29 CFR 1926.300(b)(2)). Never remove, bypass or tie back a guard to work faster, and report any guard that is missing or damaged. (29 CFR 1910.212(a)(1))
