COF vs. Pendulum Test Value

Pendulum slip (or skid) resistance data are usually expressed as PTV, Pendulum Test Value (or sometimes BPN, British Pendulum Number, or even SRV, Slip Resistance Value). The question has been asked, “What’s the coefficient of friction?” This number (dynamic COF) was calculated decades ago at the U.S. National Bureau of Standards, and can be obtained […]

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 […]

New Anti-Slip Floor Design Guidelines Aid in Safe Floor Selection

After consulting with many experts in the USA and abroad, including Safety Direct America, Specialty Architectural Products (SAP) in Toledo, Ohio has distributed four-page design guidelines (Design Guide – Anti-Slip) for floor slip resistance testing. The Slip Resistance Test Guidelines are intended to help building owners, architects, interior designers, specification professionals, and graphic designers, mainly […]

Natural Stone with Sustainable Slip Resistance Wet

Flooring that gets high foot traffic and can get wet or greasy in use needs slip resistance (or skid resistance) that stands up well under wear rather than losing its wet slip resistance after a few weeks. McDonalds Restaurants spent years in research and devised a laboratory slip test that assesses how well the wet […]

How to Prevent Slips and Falls on a Swimming Pool Deck

Unfortunately, many swimming pool decks are slippery when wet as installed! This can and too often does lead to severe accidents for both children and adults. The deck that was supposed to supply fun for the family, club members, or the public becomes a liability that causes pain, suffering, expensive medical treatment, and income losses. […]

When Should You Test Flooring for Slip Resistance?

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, […]

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 […]

Head Off Litigation with Third-Party Confidential Periodic Floor Slip Resistance Testing

Slips and falls can result from a wide range of causes. To avoid litigation your commercial property needs to be immune to claims that your negligence caused an injury. The most effective way of doing this is to have Safety Direct America periodically slip test your floors for slip resistance, and have your floor care […]

Improving the World’s Most Sophisticated Floor Slip-Resistance Safety Standards

In June’s post we discussed situation-specific slip resistance safety standards, which reflect the use or function of a floor and the friction (coefficient of friction) demands placed on it. Many U.S. floor friction standards are “one size fits all” — for instance, a wet dynamic coefficient of friction (DCOF) of 0.43 is considered adequate 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 […]
