The surface conditions of ground surface coatings which are widely used in working environments exposed to various pollutants were evaluated from a safety perspective. In this work static friction coefficient of some floor coverings exposed to different pollutants for various reasons and some shoe sole materials that are widely used in working environments were determined. The interaction between soil floor and surface contaminations were evaluated statistically. In particular the ground surface contaminated with contaminants such as water and surface cleaners which significantly reduce the security of the floor is studied. ANOVA results showed that the floor covering shoe sole samples and floor contaminants were significant for each variable of the friction coefficient (μ) (p <0.05). It was determined that the correlation between two factors and three factors between a floor covering shoe sole samples and floor surface contaminant conditions significantly affects the friction coefficient (μ). Seven floor samples used in the study were evaluated in terms of safety classification and the results ranking from the highest to the lowest were \"Granite ceramic with a glossy surface\" \"PVC linoleum coating\" \"Laminated wood parquet\" \"Matte surface ceramic\" \"Rough surfaced ceramic\" \"Matte rough non-slip fireproof ceramic \"Natural granite stone (processed)\". When the effect of floor samples on the static friction coefficient is examined safe ones according to the DIN 51097 standards for all working areas, it has been determined that \"PVC linoleum coating\" (X̄ = 0.52) \"Laminated wooden parquet\" (X̄ = 0.48) \"Granite ceramic with a glossy surface\" (X̄ = 0.46).
