A paper shredder is an inherently dangerous office item that must be used with care; it's a motorized cutting device designed to tear paper documents into tiny, unrecognizable strips. The Consumer Product Safety Commission advises that the majority of shredder-related injuries occur while feeding paper into the machine. Shredder users should be careful to keep long hair, ties, necklaces and loose clothing away from the shredder opening and to resist the urge to place hands or fingers in the shredder opening while in use. The machine should also be unplugged when not in use or when removing jammed paper. Keep the shredder and any of its power cords away from heavy foot traffic areas.
