Where Mechanical Hazards Occur

Dangerous moving parts in three basic areas require safeguarding

• The point of operation: that point where work is performed on the material, such as cutting, shaping, boring, or forming of stock.
• Power transmission apparatus: all components of the mechanical system that 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.
• Other moving parts: all parts of the machine that move while the machine is working. These may include reciprocating, rotating, and transverse moving parts, as well as feed mechanisms and auxiliary parts of the machine.
