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
editPre-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.
- Barriers and machine guards[1]
Administrative controls inform worker behavior to avoid pinch points.
- Area demarcation [1]
- Lockout–tagout[1]
- Situational awareness[1]
- Use of appropriate training,[2] work procedures, instructions, and operating manuals[1]
Personal protective equipment protects individuals exposed to the hazard by preventing objects from being pinched.[1]
