Safety analysis of slipping barefoot on marble covered wet areas

This study was conducted in order to determine the suitable surface processing techniques which will increase the safety of pedestrians, reducing the risk of slipping on wet floor coverings on which they walk barefoot. In the scope of the study, slip angle of surface-processed marbles in three different dimensions is determined by using DIN 51097 Standard “The determination of the characteristics that reduce slipping on wet, barefoot surfaces”. Slip angles were calculated with the help of an inclined plane method and by using three different surface processing techniques (polishing, honing and tumbling techniques) for five different types of marble. It was found that the parameters which affected slip angle values of the marbles were surface roughness, plate sizes, grain size of the abrasives used for surface processing, physical and mechanical properties. Statistical analysis was used to determine the relationship between these parameters. The marbles were then grouped according to safe utilization places depending on slip angle and surface roughness, according to the statistical results.
