A crushing hazard will be generated if either two movable parts are moving towards one another, or one movable part is moving towards a fixed part.

The minimum gap dimensions to minimize the risk from a crushing hazard are given in Figure C7. Care must be taken to assess the risk of a person entering the crush zone in a different body orientation to those given. Where such a risk is considered to be unacceptable, additional measures will be required to minimize the risk, e.g. the use of fixed barriers to prevent access.

In addition, consideration shall be given to the increase in hand or body part dimensions as a result of holding tools or work pieces, or from the use of personal protective equipment such as gloves or helmets.
