Cofficient of Friction and Probability of Slip

Analysis published many years ago by Pye of Britain’s Building Research Establishment quotes the probability of a slip (not a fall or injury) as varying with the coefficient of friction (COF) between the shoe and floor as follows: COF  Risk, 1 in … 0.40  1,000,000 0.38     100,000 0.34       10,000 0.31 […]

Article published in The Construction Specifier magazine talks slip resistance

Video Explains IBC Requirements for Floor Slip Resistance

The 2012 International Building Code changed slip resistance requirements for indoor floors that may get wet in use. The previously-used ASTM C 1028 friction test method is obsolete, and testing using the AcuTest method in ANSI A137.1 slip test must show a minimum of 0.42 wet dynamic coefficient of friction — but many other factors […]

Does ANSI Tile Spec A137.1 help protect you from liability for slipping accidents?

If you specify or buy flooring based on a minimum wet dynamic coefficient of friction of 0.42, you may be vulnerable to charges of negligence if a slipping injury occurs on that floor. Here we tell you why, and how to avoid the situation. American National Standards Institute (ANSI) issued its standard A137.1, “Specifications for […]

Three Common Fallacies about Floor Slip Resistance

There are three widely-held misconceptions about pedestrian slip resistance. If you’re aware of them it can help you avoid a nasty, expensive, and possibly life-changing surprise. Fallacy #1: “If a floor has a matte finish — that is, it’s not “shiny” —, it won’t be slippery when wet.” Truth is, many floors that have a matte […]
