What Are The 4 Types Of Machine Guards? - Fixanswer

Transverse motion (movement in a straight, continuous line) creates a hazard because a worker may be struck or caught in a pinch or shear point by the moving part. Reciprocating motions. Warning: Exposure to rotating shafts is the most dangerous machine safeguarding hazard.

Should be firmly secured to the machine?

Guards and safety devices should be made of durable material that will withstand the conditions of normal use. They must be firmly secured to the machine. The guard should ensure that no objects can fall into moving parts.

What kind of hazardous mechanical motion are coupling spindles and shafts?

Collars, couplings, cams, clutches, flywheels, shaft ends, spindles and horizontal or vertical shafting are examples of common hazardous rotating mechanisms . The danger increases when bolts, nicks, abrasions and projecting keys or setscrews are exposed on rotating parts.

Who is allowed to remove a machine guard?

Guards attached to mechanical equipment protect you from the moving parts of machines. Machine guards must never be removed and if a guard is damaged or missing, the machine must not be used until it can be repaired or replaced.

What are the three basic areas of a machine that require safeguarding?

Machine Guarding eTool

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.

What are the common types of hazardous mechanical motion?

The three basic types of hazardous mechanical motions and actions are: Hazardous Motions – including rotating machine parts, reciprocating motions (sliding parts or up/down motions), and transverse motions (materials moving in a continuous line);

What machine parts always require guards?
