What is the most common injury caused by working with machines unsafely OSHA?

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.

What is a equipment hazard?

Work equipment can cause injury in five main ways:- • Entrapment – where parts of the body could be caught in parts of equipment. • Impact – where the body could be crushed by moving parts or by items being processed. • Contact – where the body could touch sharp edges, hot surfaces or abrasive surfaces.

What do you mean by machine hazard?

A machine hazard occurs at the point of operation where the actual work is performed, and can be created by: components which transmit energy, such as pulleys, belts, chains, gears, couplings, or flywheels; or. other parts which move while the machine is working, including reciprocating, rotating, and transverse parts.
