Proper machine guarding is essential for protecting workers from needless and preventable injures. Any machine can be the source of injury if is not adequately and correctly guarded.
Dangerous moving parts can be classified in three basic areas:
Point of Operation – the point were work is performed on the material such as cutting, shaping, boring, or forming. The point of operation varies depending on the machine.
Power Transmission Apparatus – all components of the mechanical system that transmit energy to another part of the machine.
