For determining the relevant safety distances,

risk assessment must be carried out in accord-ance with EN ISO 12100-1 or EN ISO 14121-1. Ifthe values determined for a, b or c are betweentwo of the values given in the table, thosevalues must be applied which ensure a higherlevel of integrity.

1) Protective structures with a height of less than 1000 mm arenot mentioned as they do not ensure adequate restriction of movements.

2) Fo r danger zones above 2500 or 2700 mm see safety distancesfor reaching up.

3) For high-risk danger points, protective structures lower than1400 mm should not be used without additional technical safetymeasures.

4) The upper values apply to low risk. The lower values apply tohigh risk or other technical safety measures are applied.
