4) Entrance areas according to item 0.1 are those areas that can be accessed through entrances directly from outside and where moisture may be brought in from outside (see also Point 6, Paragraph 3, Use of means for collecting dirt and moisture). For neighbouring areas or other large spaces, Point 4, Paragraph 10 must be observed. 5) Stairs, ramps in accordance with items 0.3 and 0.5 are those onto which moisture may be introduced from outside. For neighboring areas Point 4, Paragraph 10 must be observed. 6) If a uniform floor covering has been laid throughout, the displacement space may be lowered to V 4 on the basis of a hazard assessment (taking into account the cleaning method, the work processes and the amount of slippery materials likely to be on the floor). 7) The pedestrian areas that are not subject to slipping hazards due to the influence of the weather, such as heavy rain or moisture that has been carried indoors.
