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
Before you start a task, look for anything that moves, closes, rolls, swings or turns, and anything that moves toward a fixed object. Common ones are rollers and belts, chains and sprockets, doors and hinges, tailgates and dump bodies, and the gap between a load and a wall. Point them out to the crew, especially to new workers.
ASK THE CREW
When do we lock out a machine before reaching in, and who is authorized to do it?
