Pinch Points

A pinch point, often referred to as a nip point, is defined as any point where it is possible for a body part to get caught between moving and stationary sections of equipment.

Mining equipment contains parts that may cause bodily harm if mishandled. Types of pinch point injuries include the following:

• Amputations
• Lacerations
• Contusions
• Crushing of tissues and bones
• Broken bones

Miners must adhere to the following safety precautions related to pinch points:

• Ensure that all covers and protective shields that protect against the pinch point hazards on equipment and machinery are in place.
• Wear snug clothing, remove jewelry, and tie long hair back or secure it under a cap before working near pinch point hazards.
• Place warning labels adjacent to pinch point hazards.
• Never place hands near or reach across rotating mechanical parts. Miners must be alert whenever they place their fingers, hands, toes, or feet between any objects.
• Do not operate equipment or machinery without required guards or shields.
• Shut off and de-energize equipment or machinery before performing maintenance or repairs.
• If necessary, follow lockout and tagout procedures.
• Replace pinch point guards or shields after completing maintenance or repairs on equipment and machinery.
