Floor surface immediately inside accessible entrance
The floor inside an accessible entrance must be firm and even, at the same level as adjacent surfaces, and should reduce moisture tracking into the building unless the external access area already limits this.
A floor immediately inside any accessible entrance should –
(a) have a surface which is firm and even;
(b) where there are changes in flooring surface, be at, or about, the level of any adjacent flooring surface; and
(c) have a surface that will reduce the risk of tracking moisture into the building (e.g. from shoes or wheelchair wheels). However, this provision is not required where the external access area is designed and constructed to limit the tracking of moisture into the building.
