Technology can make machines safer, but as long as workers need machines to help them process material – to cut, shear, punch, bend, or drill – they will be exposed to moving parts that could harm them. Much of the danger occurs at the point of operation, where the work is performed and where the machine cuts, shears, punches, bends, or drills.
