Machinery is commonplace within factories and industrial environments, but it comes with risks attached. The dangers posed by sharp edges, clamps, presses, hotsurfaces and moving parts are clear, and operators must be protected from them.
Aside from training, operational precautions are essential for the safe use of machinery. The first approach should always be to remove hazards by installing physical guarding or protection. Clear warning signs should also be fitted.
The addition of machinery safety systems that use switches, sensors, and opto-electronicprotective devices to monitor how the operator is interacting with a machine is a secondary way to mitigate risks when physical guarding is impractical.
