Machine Guarding 3
Machine Guarding 3 : Moving machine parts have the potential to cause severe workplace injuries, such as crushed fingers or hands, amputations, burns, or blindness. Safeguards are essential for protecting workers from these preventable injuries. Any machine part, function, or process that may cause injury must be safeguarded. When the operation of a machine or accidental contact injure the operator or others in the vicinity, the hazards must be eliminated or controlled. This page contains general information on the various hazards of mechanical motion and techniques for protecting workers. Machine guarding hazards are addressed in specific standards for the general industry, marine terminals, longshoring, and the construction and agriculture industries. Employee exposure to unguarded or inadequately guarded machines is prevalent in many workplaces. Consequently, workers who operate and maintain machinery suffer approximately 18,000 amputations, lacerations, crushing injuries, abrasions, and over 800 deaths per year. Amputation is one of the most severe and crippling types of injuries in the occupational workplace, and often results in permanent disability. This *eTool focuses on recognizing and controlling common amputation hazards associated with the operation and use of certain types of machines. Introduction to Machine Guarding: All machines consist of three fundamental areas: the?point of operation, the?power transmission device, and the?operating controls. Despite all machines having the same basic components, their safeguarding needs widely differ due to varying physical characteristics and operator involvement. The following pages address the general requirements for machinery set forth by OSHA, the motions and actions that contribute to different machine hazards, and additional considerations that entail overall machine and operator safety: (a) General Requirements; (b) Hazardous Motions and Actions; (c) Additional Safety Considerations. Safeguards: (a) Guards, (b) Devices. Point of Operation: The point of operation is where work is performed on the material, such as cutting, shaping, boring, or forming of stock. Power Transmission Device: The power transmission apparatus is all components of the mechanical system which transmit energy to the part of the machine performing the work. These components include flywheels, pulleys, belts, connecting rods, couplings, cams, spindles, chains, cranks, and gears. Operating Controls: Other moving parts refers to all parts of the machine which move while the machine is working. These can include reciprocating, rotating, and transverse moving parts, as well as feed mechanisms and auxiliary parts of the machine.
