The easy way to consider slip risk

Since early studies in the 1950's and 1960's it has been argued that 40PTV approximates to 1 in 1 million slip risk and 20 PTV appriximates to 1 in 2 slip risk. In SlipAlert terms the higher the SlipAlert Test Value (STV) the greater the risk.

Every point over 130 increases the slip risk

Floor Risk Certificate

The certificate includes measures of slip risk taken in best/worst cases and taken in normal use of the floor. It should also indicate the normal use of the floor, the approximate footfall (how many people walk across the floor each day), as well as details of the normal types of contamination, and the cleaning regime (method, frequency, cleaning materials etc).

Updates

A floor risk certificate is a "living document" and additional measures or changes to the floor will be appended to the certificate file. The risk category coudl change if the floor is modified, if the cleaning or likely contamination is modified, or if the use of the floor changes in a material way (e.g. more people, or more vehicles or different footwear conttrols)
