ALL EMPLOYERS MUST:
Hazardous Mechanical Motions and Actions
Recognition of these hazards is the first step toward protecting workers from the danger they present.
- Collars - Couplings - Cams
- Clutches - Flywheels - Shaft ends
- Spindles - Meshing gears - Horizontal shafts
- Vertical shafts
Rotating motions can grip clothing, and through mere skin contact force a limb into a dangerous position. The danger increases when projections such as set screws, bolts, nicks, abrasions, and projecting keys or set screws are exposed on rotating parts.
- Rotating motions
- Reciprocating motions
- Transversing motions
The danger of cutting action exists at the point of operation where finger, arm and bodily injuries can occur and where flying chips or scrap material can strike the head, particularly in the area of the eyes or face.
Defeating, altering, or removing safeguards can cause injury to co-workers and can leave the person performing such actions liable under the OSHA Act of 1970.
Before beginning the process of guard procurement, design, or installation, the equipment manufacturer should be consulted for advice.
OR ANY COMBINATION OF POWER SOURCES
Before beginning the process of procurement, design, or installation, the equipment manufacturer should be consulted for advice.
Defined as: “The area on a machine where work is actually performed upon the material being processed.”
