When reaching around edges in any position, the safety distance of freely articulating upper limbs is given in Figure C3.

The radius of the movement about a fixed edge is determined by the reach of given body parts. The safety distances assigned shall be respected as a minimum if the body part concerned is not to be allowed to reach a danger point.

Of special importance is the danger area which can be reached when these body parts are introduced through slots.

When applying safety distances, it is to be assumed that the basic joint component of the relevant body part is in fixed contact with the edge. The safety distances apply only if it is ensured that further advance or penetration of the body part towards the danger point is excluded.

" Either the diameter of a round opening, the side of a square opening or the width of a slot opening.
