Floor slip resistance testing is an essential process for ensuring safety in public spaces, workplaces, and homes. It helps to identify the level of slip resistance (or COF) of a floor surface, which is crucial in preventing injuries resulting from avoidable slips and falls. The most common floor slip resistance testing technique around the world […]

Maximum Coefficient of Friction is not Limited to 1.00
It’s sometimes assumed that coefficient of friction (COF) has a maximum theoretical and practical value of 1.00. This isn’t true; there is no maximum. It is true that values exceeding 1.00 are so slip-resistant that their actual value is often of little interest. Some COF measuring instruments, such as BOT-3000E and English XL, are not […]
Article published in The Construction Specifier magazine talks slip resistance
John C. Sotter and George Sotter of Safety Direct America were published in the July issue of The Construction Specifier magazine with an article talking about floor slip resistance and keeping floors safe for pedestrians. The article talks about the latest International Building Code (IBC) requirements for slip resistance, and its limitations as far as […]
OSHA’s “Suggestion” for Minimum Floor Coefficient of Friction (COF)
We often hear the question, “What does OSHA require for floor slip resistance?” The answer is that OSHA doesn’t require anything, but nevertheless has caused a lot of confusion for employers and the public on this subject. There has never been an official OSHA slip test or safety standard for flooring. In a nonmandatory appendix […]
Do All Pedestrian Ramps Need the Same Coefficient of Friction?
The minimum safety standard for coefficient of friction for a pedestrian ramp should depend on the angle of the ramp and the weight of the separate load (shopping cart, wheelchair, gurney, etc.), if any, the pedestrian is controlling. However, that’s not how American safety standards are written. In the USA, traditionally safety standards for slip […]
