This booklet investigates the standards that bring about slip and fall incidents and establishes a courting among the coefficient of friction (COF), flooring slipperiness and flooring roughness. It additionally examines human belief of slipperiness via measured coefficient of friction (COF). at the foundation of questionnaire surveys between production staff, it identifies capability possibility elements and assesses human perceptions of slipperiness. It additionally makes use of a tribology method of relate the interplay among contaminants, flooring and sneakers materials.

In an earlier study [5], the floor roughness did not appear as a suitable indicator of floor slipperiness under an oily condition due to the negative correlation. 8). This implies a strong relationship between roughness and the measured COF on the tested floors. Thus, roughness is considered suitable as an indicator of floor slipperiness. References 1.

1 presents the Spearman’s rank correlation coefficient (ρ) between subjective scores of floor slipperiness and COF values measured with a portable skid resistance tester. This is the most common method used to measure the direction and strength of association between two variables [3]. 600 average value of COF for each condition was used because the five friction measurements were recorded during each tested condition. 0), the stronger is the association between the variables [3]. 8). 632). 2) compared to others.
264 cSt). 3 Friction and Roughness Measurement In friction measurement, the head of pendulum was fitted with three different types of footwear material slider. These sliders were moved by a spring system releasing a pendulum out in a horizontal position. After this process, the friction values could be directly read from the measuring scale. The measurements were taken in the direction of the walking path on the selected floors (Fig. 10). Five measurements were taken with different footwear material/floor/testing conditions.
