Abstract
People were filmed walking and running, with shoes and barefooted, wet and dry, against a screen in order to obtain data on the presentation of feet to floors. This information, together with other available data, was used to design a range of machines for measuring the coefficient of friction between shoe and flooring materials. The latest development, the Tortus floor friction tester, measures the coefficient of friction on floors and enables the changes in value to be recorded. A brief description of the method of measurement is given, together with typical results.
The state of cleanliness of a floor is critical in terms of safety and some of the difficulties resulting from incorrect cleaning procedures are indicated. Floor surfacing materials are usually chosen to meet specified uses. With few exceptions, the specification of particular footwear is only given for some industrial purposes. Optimum accident prevention would require choice of the most suitable combinations of these materials.
