Machine Safeguarding Basics
In Running Nip Points are caused by the rotating parts. Parts rotate in opposite directions while their axes are parallel to each other. In running nip points are particularly hazardous because at the nip point the equipment can snag skin, hair, loose clothing, jewelry etc. and pull then into the equipment. Severe injury can result depending on the equipment in use.
There are 3 main types of Nip Points:
- Parts rotate in opposite directions while their axes are parallel to each other. Examples include gears and cylinders.
- Nip Points can be created between rotating and tangentially moving parts. Examples include belt and pulley, chain and sprocket, etc.
- Nip Points can occur between rotating and fixed parts. This creates a shearing, crushing or abrading action. Examples include spoked handwheel/flywheel, screw conveyor and bench grinder.
Nip Points should be identified and properly guarded at all times.
Machine operators should never remove guards while the equipment is in operation
Machine guarding problems should be reported immediately
Machinery should never be operated with loose clothing, exposed long hair or jewelry.
Hazards created by industrial equipment can cause death or severe injury including amputations, fractures, cuts, crushing injuries, burns and electric shock. Machine safeguarding is critical to keeping employees safe from dangerous equipment. Never operate a machine that is not properly guarded.
