A. reference plane
B. hip joint
C. protection structure
Irregular openings and accessibility from below: The slot openings > 180 mm, and square or circular > 240 mm do allow access of the entire body.

EN ISO 13857 – reference table – upper limbs
Reaching upwards
If there is a low risk from hazard zone, then the height of the hazard zone (h) shall be 2 500 mm or more
If there is a high risk from the hazard zone, then the height of the hazard zone (h) shall be 2 700 mm or more.
- Hazard zone
- Reference plane
- Protective structure
Reaching over protective structures
a. height of hazard zone
b. height of protective structure
c. horizontal safety distance to hazard zone
The table below (high risk situations) does not consider protection structures with height <1000 mm, because they don’t restrict sufficienty body movement.
Protective structures with height <1400 mm should not be used without additional security measures.
ln low risk situations protective structures of height 1000 mm are acceptable. If the safety distance in the table below is expressed with a dash, then the distances according to the size of the net must be used. Meshes 32×67 mm or 40×40 mm have a minimal horizontal safety distance of 200 mm. Meshes 60×11 mm are required for a horizontal safety distance of bellow 200 mm.
