Machines such as power saws, shears, guillotine cutters, presses, milling machines, fans, conveyor belts, palletisers and revolving drums can slice, crush, and tear off workers' body parts. Cutting action hazards involve rotating, reciprocating or transverse motion, where finger, head and arm injuries can occur and where flying chips and scrap material can strike a workers eyes or face. The list of possible machinery-related injuries created by moving machine parts is long - amputations, lacerations, crushing injuries, and abrasions, Machine safeguards are essential for protecting worker from these preventable injuries. machinery The in-running nips between the belts and head pulleys require fencing that encloses dangerous parts with rigid guards that prevent reach into the conveyor from any angle, including underneath.
