Protection against reaching through openings, dimensions for lower limbs

The values in the following table apply only to persons who are at least 14 years old. Values in mm.

Distances to prevent crushing, EN 349

Annex B of EN ISO 13857 describes special instances where a safety device only restricts access by a standing person. Where the risk is one of slipping - and this can never be completely excluded in the normal industrial environment - the values that it gives are not practical. Therefore we have not quoted them.

The coloured area shows which part of the body is restricted by the size of the opening. If a slot is < 75 mm long the safety distance can be reduced to > 50 mm.

Slots > 180 mm and square or circular openings > 240 mm permit full body access. Additional protective measures must be taken.
