TY - JOUR PY - 2018// TI - Subjective assessments of floor slipperiness before and after walk under two lighting conditions JO - International journal of occupational safety and ergonomics A1 - Li, Kevin W.

The participants were tested under shoes, floors, surface, and lighting conditions. They gave floor slipperiness ratings before and after a gait trial. The perceived sense of slip (PSOS) was collected. It was found that the perceived floor slipperiness (PFS) before walking was affected significantly by the lighting, floor, and surface conditions. Relative low PFS values were recorded under wet and detergent contaminated conditions at normal daylight condition as compared to those in the dimmed condition. The perceived floor slipperiness after the gait was significantly affected by the floor and surface conditions. The PSOS was highly correlated with the PFS after trial. The regression analyses results indicated that both the coefficient of friction (COF) of the floor and lighting were primary predictors of the PFS before a gait. The COF and walking speed were the primary predictors of the PFS after a gait.
