They are not only serious environmental safety issues but also important occupational safety and health problems. Floor slipperiness has been identified as one of the critical factors affecting the risk of slip and fall. Floor slipperiness may be quantified by measuring the coefficient of friction of the floor. It may also be determined by human judgements. How people perceive floor slipperiness is an important topic affecting the likelihood of a slip/fall incidence. The purpose of this study was to determine the difference of perceived floor slipperiness by human subjects under different floor, floor surface condition and sensation mode. The results showed that the effects of the three factors on the subjective ratings were statistically significantly (p<0.0001). The two-way and three-way interaction effects of the factors were also significantly (p<0.0001). Based on our data, a regression model was established to estimate the floor slipperiness rating of human subjects considering the floor surface condition and floor roughness. The results of the study are beneficial in housekeeping and safety training at workplaces to reduce slip and fall incidences.
