Fall of persons from smooth and wet surfaces

I came on official work to a project site and staying in our guest house.  Yesterday morning, I saw one server skidding on smooth mosaic floor, which was mopped a few minutes ago. He regained his position before fall and didn't suffer any injury,  but could have happened. 

I too had such escapes, quite a good number of times at home, which is a marble surface. 

Use of tiles with smooth finish is increasing everywhere. Airports, end to end, have such floors. It is, even,  difficult to have normal walk. 

It's my opinion to ban smooth floors and may permit on side walls. National Building Code needs such provisions to protect persons or occupants.
