“…Particular attention is however needed in the definition of the various involved variables related to the nature and the characteristics of the shoe surfaces that are in contact with a certain floor surface, and also to the nature of possibly present polluting substances [16,17]. This study, e. g., only takes into account water as a possible pollutant.…”

The causes of slip are multiple and depend on the mechanical and aesthetic characteristics of the surfaces in contact, and on external elements related to the specific situation. The non-slip characteristics of a surface can be evaluated by measuring the dynamic friction coefficient (DCoF). Hazardous conditions generally appear and progress over time as a result of use, aging-related natural degradation, lack of or incorrect cleaning and maintenance. This study focuses on the characteristics of roughness profiles of the surfaces in contact and aims at the identification of those roughness parameters that can allow a more reliable evaluation of both the "slip risk index" and of its change over time due to alterations of surface texture. The sliding-contact factor,ηsc, is identified as a candidate for the evaluation of slip risk, and is represented by a dimensionless number that can be calculated using only the data of some roughness parameters, measured by a handheld instrument (Portable Surface Roughness Measuring Instrument), portable and easy to use. The sliding-contact factorηsc allows the evaluation of the "slip risk index" of dry and water-contaminated surfaces and can increase the accuracy of the assessment of the "slip risk index” if evaluated through the DCoF only.Article Highlights A new parameter, termed sliding-contact factor ηsc is defined and is correlated with the dynamic friction coefficient. A classification of the slip risk index can be performed by means of the introduced sliding- contact factor ηsc. The present work can represent a basis for the development of a new international standard for slip-risk assessment.

“…Background information regarding surface roughness measurements and the desired settings of a profilometer or a surface roughness meter are available in the research literature. A surface with a higher R pm value, the lower drawing in Figure 6.7, is preferred to a surface that has a lower R pm value, the top drawing in Figure 6.7 (Chang, 2004).…”

The study of slips and falls has traditionally focused on body kinematics and tribology. However, this strictly mechanical approach does not allow scientists to assess the importance of each component in relation to the complete system, and thus it lacks integration. The purpose of this chapter is to present and demonstrate the components of a broad analysis for in-depth understanding of slips and falls while walking on level surfaces. In most slipand-fall studies, balance analysis is simplified and attributed to the point of heel contact. To determine sufficient fall prevention strategies, however, one must analyze balance before the critical moment of lost control. Such an approach requires the sciences of biomechanics, mechanics, anatomy, and neuromuscular control, as well as tribology. Causes of slips and falls are complex, and prevention approaches are often reactive, driven by high-injury trends and lawsuits. Prevention strategies need to be more proactive: Understanding the causes of accidents can help in identifying and correcting hazards before they cause problems. Examples include reporting incidents, selecting the right flooring, selecting footwear, and implementing proper floor-cleaning procedures. A combined effort among all members of the organization, including communication across the entire work system, is critical to the success of slip-and-fall prevention efforts. Sl ips and falls represent either the highest or second-highest type of workers' compen

“…Since 1988, many studies have showed the importance of slip resistance measures [2]. Further, surface texture is an important effecting the friction mechanism between shoes and floor surface [2,3]. In 2003, investigating development a new analyzing model to understand the friction and wear mechanism, and relevant characteristics of the sliding interfaces between footwear and underfoot surface [4].…”
