ANALYSIS OF MEASUREMENTS OF SLIP RESISTANCE OF SOILED SURFACES ON SITE

The present study hinges on the use of the PFT (Portable Friction Test er) to assess the slip resistance of floors on site and aims to analys e measurements of slip resistance (602 measurements) that were carried out in 27 different firms on moistened, greasy or dirty floors, The c ontribution of different factors to the slipperiness of a given soiled surface can thus be identified or confirmed: quantity and viscosity o f the soil, permeability and roughness of the floor, cleaning efficien cy and uniformity, In particular, we observed that cleaning a soiled s urface does not immediately lead to an increase in its slip resistance , The present study is exploratory in nature since so far no publicati on has been devoted to the analysis of measurements of slip resistance of floors in more than one firm.
