Coefficient of friction, walking speed and cadence on slippery and dry surfaces: shoes with different groove depths
Objective. The present study aimed to determine the coefficient of friction (COF), walking speed (WS) and cadence while walking on slippery and dry surfaces using shoes with different sole groove depths to predict likelihood of fall. Background. Design of shoe sole groove is crucial to prevent slipping during walking. Methods. 22 healthy young men (mean age 24.5, body mass index 22.5) volunteered for this semi-experimental study. Six different conditions of the test (combination of three shoes and two surfaces) were defined and the condition was repeated three times. In total, 396 trials (22 subjects × 3...
Slip-related characterization of gait kinetics
Investigation of pervious concrete as a slip-resistant walking surface Slip-related falls are a significant health problem, particularly on icy walking surfaces. Pervious concrete, a material allowing rapid exfiltration of melted ice from the walking surface, may help reduce slipping risk. Therefore, the purpose of this study was to compare slipping characteristics of traditional and pervious concrete walking surfaces in icy conditions using kinetic biomechanical analyses. We hypothesized that pervious concrete, in comparison to traditional concrete, would be characterized by less severe ice-related...
Assessment of slip resistance under footwear materials, tread designs, floor contamination, and floor inclination conditions
Slip and fall incidences are common in our daily lives. They are not only important environmental safety issues but also important occupational safety and health problems. The purpose of this study was to use the Brungraber Mark II to measure the friction so as to investigate the effects of the shoe sole, surface condition and the inclined angle of the floor and their interactions on friction coefficient. The results of the study showed the effects of all the main factors and their interactions were significant (p<0.001). Engineering designs & ergonomic interventions in slip & fall prevention...
Development of a more accurate assessment of roughness parameters for flooring
Slips and trips are the most common cause of major injuries at work and they occur in all workplaces; 95% of reportable major slips result in broken bones. In a typical year, slips and trips account for over 33% of all reported major injuries and approximately 20% of over-3-day injuries to employees. There is rarely a single cause of a slipping accident, and a holistic approach is required when assessing slip potential. A major contributing factor in any slip accident is the interaction of the pedestrian's heel, the floor surface and any contaminants present. It is therefore important to characterise...
Assessment of slips safety information/literature provided by flooring and footwear suppliers
Nearly 11,000 workers suffered serious injury as a result of a slip or trip in 2007. A key element of HSE's work to reduce slips and trips is to raise awareness of how slip risks can be controlled through the use of suitable flooring and footwear. Source:
