Foot slippage is the most widespread unforeseen event causing falls on the same level, and a potentially contributing factor to falls from height and falls to a lower level. Statistical data on the number of slip-related accidents at work show the importance of the problem of slipping and indicate the need to continuously improve preventive measures designed to reduce injuries related to slipping, tripping, and falling (STF) on the same level. It is therefore necessary to continuously and insightfully analyze the causes of falls and undertake efforts to eliminate the occurrence of slip- and trip-induced workplace accidents. The occurrence of slips and trips is primarily related to the type and quality of floor surfaces, but it also depends on the biomechanical characteristics of the lower limbs in the transitional phases of walking gait, sole material and tread, human factors such as age, weight, and motor and vision function, the ability to adapt to the floor surface conditions, as well as on a number of factors linked to the workplace environment and work organization. This problem is going to escalate as a result of the higher retirement age, due to which many persons over the age of 60 will have to continue working, often in hazardous conditions.
