Many building owners find themselves in trouble after a refurbishment or new build, because the flooring is unexpectedly slippery when wet. An entrance lobby, restroom, pool deck, spa, or factory floor are common locations where this problem occurs. When should flooring be tested for slip resistance? Some architects might say, “Never.” Many lawyers might say, […]

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 […]
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 […]
Situation-Specific Floor Slip Resistance Testing Standards
In the USA, pedestrian slip resistance standards for flooring have traditionally been pass-fail. For instance, a coefficient of friction (COF) of 0.60 might be considered “safe” but 0.59 was “not safe.” This applied to any situation provided the floor was level. Recently the American National Standards Institute (ANSI) has published some standards that are a […]
Variables that Affect Slip Resistance of Polished Concrete
At the 6th Annual International Concrete Polishing & Staining Conference in Atlanta in September 2013, a panel discussion was organized and chaired by Ken Fisher of Nu-Safe. On the panel were the manufacturer of the BOT-3000E tribometer (floor slip resistance test meter); an Orlando attorney for large international property owners; and slip and fall prevention […]
Misleading ASTM C 1028 Friction Test Continues to Wreak Havoc in the USA
Misguided investments of hundreds of millions of dollars in slippery flooring … pain, suffering, and financial losses to accident victims and their families … lawsuits by the thousands … and lack of consumer confidence in ceramic tile and other hard flooring: these are some of the consequences of a poorly-conceived floor “slip-resistance” test — ASTM […]
Safe Coefficient of Friction Values for Inclined Surfaces (Ramps)
At Safety Direct America, we are experts in slip resistance (or coefficient of friction) testing. There is little information available in regards to what COF is required for different angles of pedestrian ramps.This blog entry discusses some published information on the subject of how much coefficient of friction is needed on various types of ramps […]
