									 Gone in less than Seconds
  Moment’s inattention—and a hand is caught in machinery. A
    single misstep; a foot slips in. Maybe the amputation is
 immediate, or perhaps the doctors determine later that a limb
   is too damaged to repair. Either way, it could have been
                              Most Hazardous Exposures
Four exposures have been identified by the Government as the leading causes of
nonfatal workplace amputations:
•     Machinery and equipment. The greatest percentage of nonfatal
      amputations occurs when workers are caught in or crushed by running
      machinery or equipment, or when they are caught in or crushed by
      machinery that cycles unexpectedly.
•     Parts or materials. The second most common situation that leads to
      nonfatal amputations occurs when workers are caught in, crushed by, or
      struck against parts and materials—for example, when a load shifts
      unexpectedly or stored materials collapse on a worker.
•     Vehicles. Motor vehicle accidents are the leading cause of fatal amputations,
      and the third-leading cause of nonfatal amputations.
•     Hand tools. Hand tools, such as handheld circular saws, are the fourth most
      common cause of nonfatal amputations.
                               Watch For These Hazards
When you look for amputation hazards on machinery and equipment, remember
these hazards:
•     Pinch points, where two parts move together and at least one of them is
      moving in a circle. Pinch points often occur along belt drives, chain drives,
      gear drives, and feeder rolls.
•     Wrap points, where there is an exposed piece of rotating machinery, such as
      a rotating shaft, especially if it extends beyond bearings or sprockets.
      Because they can catch clothing or fingers more easily, shafts that are
      splined, square, or hexagonal are generally more dangerous.
•     Shear points, where two moving parts move across each other or a single,
      sharp edge moves with enough speed or force to cut. Chain or paddle
      conveyors, trimmers, forklifts, and enclosed augers have shear points.
•     Crush points, where two objects are moving toward each other, or one
      object is moving toward a stationary object. Gears are common crush points.
•     Pull-in points, where objects can be pulled into equipment. Feeder rolls or
      grinders are common pull-in points.
•     Thrown objects, hurled by equipment with moving parts. Chippers are
      known to be common sources of thrown objects.
