Pinch point hazard

From Wikipedia, the free encyclopedia
Pinch point hazards may be present with pulleys. For example, if fingers get caught between the moving belt and the pulley wheel.

A pinch point or pinch point hazard is a common class of mechanical hazard where injury or damage may be done by one or more objects moving towards each other, crushing or shearing whatever comes between them.[1] A nip point is a type of pinch point involving rotating objects, such as gears and pulleys.[2] Injuries can range from minor such as blisters to severe like amputations and fatalities.[3] Examples of pinch point hazards include gaps in closing doors and objects swinging or being lowered near fixed objects.[4]

Common causes of injuries

[edit]
  • Poor situational awareness[1]
  • Proximity to mobile equipment and fixed structures[1]
  • Loose clothing, hair or jewelry getting caught in rotating parts or equipment[1]
  • Inadequate safety barriers[1]
  • Handling errors[1]
  • Wrong work procedures or tools[1]
  • Reaching into moving equipment[1]

Safety controls

[edit]
A hazard sign is an example of an administrative control

Pre-work hazard inspections can be performed to identify pinch point hazards. These hazards can be managed with control methods, listed below according to the hazard control hierarchy.[1]

Engineering controls physically prevent objects from entering the pinch point.

Administrative controls inform worker behavior to avoid pinch points.

Personal protective equipment protects individuals exposed to the hazard by preventing objects from being pinched.[1]
