HAND & POWER TOOLS – AMPUTATION HAZARDS

What are the sources of amputations in the workplace?

Amputations are some of the most serious and debilitating workplace injuries. They are widespread and involve a variety of activities and equipment. Amputations occur most often when workers operate unguarded or inadequately safeguarded mechanical power presses, power press brakes, powered and non-powered conveyors, printing presses, roll-forming and roll-bending machines, food slicers, meat grinders, meat-cutting band saws, drill presses, and milling machines as well as shears, grinders, and slitters. These injuries also happen during materials handling activities and when using forklifts and doors as well as trash compactors and powered and non-powered hand tools.  Besides normal operation, the following activities involving stationary machines also expose workers to potential amputation hazards: setting up, threading, preparing, adjusting, cleaning, lubricating, and maintaining machines as well as clearing jams.

 What types of machine components are hazardous?

 The following types of mechanical components present amputation hazards: 

 What kinds of mechanical motion are hazardous?

 All mechanical motion is potentially hazardous.  In addition to in-running nip points (“pinch points”)—which occur when two parts move together and at least one moves in a rotary or circular motion that gears, rollers, belt drives, and pulleys generate—the following are the most common types of hazardous mechanical motion:

 Work practices, employee training, and administrative controls can help prevent and control amputation hazards.  Machine safeguarding with the following equipment is the best way to control amputations caused by stationary machinery:
