“…The surface of the flooring materials used in buildings should be non-slip [11,12]. It has become crucial to determine the slip risk assessment of material surfaces used as floor coverings [13,14]. Slip resistance is caused by the interaction between the shoe sole and the surface of the floor covering material.…”

The occurrence rate of occupational accidents caused by slipping and falling is 50% worldwide. Determining the slip safety risk is necessary to minimize the accidents caused by slipping in pedestrian walking areas. By on-site testing, this study aims to determine the slip risks of floor coverings used in walking areas with many pedestrians in public service buildings (PSB). For this purpose, on-site measurements were performed in two environments and six locations in PSB using portable GMG 200 and pendulum testers operating according to DIN 51131 and TS EN 14231 standards. These tests were performed on four-floor coverings with polished surface treatment in PSB. Since the floor coverings measured have a polished surface, it can be seen that the dynamic friction coefficients (DCOF) values are very low, and the slip risks are high. By statistically analyzing the slip test data using the K-means method, a new safety classification was made according to the usage areas of floor coverings. To minimize the risk of slip safety, especially for students, patients, and employees in PSB, it is recommended to use floor coverings with high DCOF values and low slip risk.

“…The friction measurements conducted in the laboratory were normally performed to explore the mechanisms of slipping of the shoe sole on the floor. Studies testing the effects of the floor, footwear, floor inclined angle, and floor surface contaminations on slipperiness have been reported [14,18,[23][24][25][26][27][28][29][30][31][32]. There were also studies comparing the testing parameters, test methods, reliability, and validity of friction measurement devices [13,17,[32][33][34][35].…”

Slips and falls are common occupational incidents worldwide. The friction on a floor surface is one of the critical environmental factors affecting the risk of a slip. In this research, we conducted friction measurements on stone and ceramic floor tiles under dry, wet, and water–detergent (WD) solution covered conditions using a horizontal pull slip meter (HPS). Our purposes were to quantify the slip resistance of commonly used stone and ceramic floors under different surface conditions and to validate the curvilinear relationship between the coefficient of friction (COF) and surface roughness of the floors proposed in the literature. The COF data were analyzed together with a surface profile parameter (Ra) of the floor samples. The results showed that the COFs of the stone floors were significantly (p < 0.0001) higher than those of the ceramic floors. All the floors under the dry conditions were slip resistant when adopting the ANSI 1264.2 criterion. Two and five ceramic floors were not slip resistant under the wet and WD solution covered conditions, respectively. Three polynomial regression equations were established to describe the relationship between the COF and Ra. The curvilinear functions of these models indicate that the three-zone (initial growth, steady-growth, and plateau) concept concerning the COF–Ra relationship in the literature was valid when static COF values measured using an HPS were adopted. In addition, the three-zone concept was valid not only on WD solution covered surfaces but also on dry and wet surfaces.

“…Wetting and drying and freezing and thawing have proven to be important physical processes affecting physical mechanical properties of natural stones, which have been investigated by several researchers, e.g., [1][2][3]. However, studies concerning the influence of these factors on the slip resistance of natural stones are very few focusing mainly on the investigation of other affecting parameters, such as floor roughness, liquid viscosity and shoe materials [4], or floor surface finishes [5].The effect of mineralogical and petrographic characteristics, chemical properties, physical and mechanical properties, the surface finish, and its dryness or wetness on the slip resistance were identified by Çoşkun et al [6]. Therefore, this study investigates any potential effect of freezing-thawing on the slip resistance of dimension stones for flooring considering their surface type as well as the impact of wet or dry environment.…”

The effect of freeze–thaw cycling on the slip resistance of dimension stones was investigated. Slip and frost resistance of limestones, granites and marbles were determined via pendulum tester in dry and wet conditions and controlled freeze–thaw cycles, respectively. Unpolished surfaces under dry conditions (mainly granites and marbles) were positively affected by freezing-thawing. In wet surfaces no significant change was observed. Polished surfaces were not affected even after 100 freeze–thaw cycles. Electron microscopy showed increased wear, hence roughness, of unpolished surfaces after freezing–thawing; homogeneity of polished surfaces prevented slip resistance from being significantly affected.
