How to Get Reliable and Useful Floor Slip Resistance Test Results

Slip and fall injuries can carry total liabilities that are often in the hundreds of thousands of dollars or even more. Investment in flooring is long-term and often involves appreciable capital, whether you are an individual homeowner or have a string of large office buildings and shopping centers. Though the charges for floor slip resistance […]

Safety Direct America is Still Running at (almost) Full Speed

At this writing the death toll of Americans from COVID-19 is over 34,000. With the world upside down, the last thing you need is to have a slip-and-fall accident. Falls cause 28,000 premature deaths in the USA every year. Most of these deaths (some of which occur prematurely but months after the fall) are due […]

CoatingsPro article: How to Specify a Slip-Resistant Floor Coating

An article in the March 2020 edition of CoatingsPro™ Magazine details how to specify an anti-slip floor coating, specifically a transparent one. (A printable version of the article is also available.) After establishing a reliable method to determine wet slip resistance, the article discusses initial slip resistance safety criteria; durability testing of the coating’s slip […]

Surveillance to Detect Slip and Fall Hazards on Commercial Floors

Surveillance of floors to detect spills, dropped produce, and other hazards is an important part of many safety plans, particularly on floors that have poor wet slip resistance. This includes most floors in customer areas of supermarkets. In one supermarket slip and fall case, a court ruled that inspections every 12 minutes were necessary in […]

New Study Shows Sotter Engineering to be one of World’s Most Accurate Pendulum Floor Slip Test Labs

A recent global interlaboratory program “Slip Resistance Proficiency Testing — Pendulum Friction Tester,” showed Sotter Engineering Corporation’s Safety Direct America (SDA) floor slip resistance testing laboratory to be one of the world’s most accurate in use of the pendulum skid tester. The pendulum is a national standard for pedestrian floor and tile slip resistance testing […]

Financial losses from slip and fall accidents

Slip and fall accidents are the #1 reason Americans show up at emergency rooms, according to data from the CDC. Slippery floors are a silent epidemic in America, and lawsuits are filed daily across the nation involving major injuries and deaths from slippery floors. Unless the negligent party is the victim’s employer, the victim of […]

Roughness and Wet Floor Slip Resistance

We all know intuitively that roughness has a lot to do with floor slip resistance. Very smooth floors tend to have low wet slip resistance, and to some types of shoe solings (as on some dancing shoes) can have low dry slip resistance too. However, “rough” appearing floors aren’t always slip-resistant, and this has to […]

Floor Slip Rating: SCOF vs. DCOF

Static coefficient of friction (SCOF) was formerly used to measure the slip resistance of a wet floor in the USA, but the test method (ASTM C1028) was withdrawn by the ASTM in 2014. Experts in the USA now know to use dynamic coefficient of friction (DCOF), as the rest of the world has been using […]

ANSI A326.3 Acutest Does Not Predict Likelihood of Slip

A widely used floor friction test, American National Standards Institute A326.3, states in its introduction that “it can provide a useful comparison of surfaces, but it does not predict the likelihood a person will or will not slip on a hard surface flooring material.” The test assesses wet dynamic coefficient of friction (DCOF) using the […]

How does ANSI DCOF compare with Pendulum Test Value?

The most recent American National Standards Institute (ANSI) dynamic coefficient of friction (DCOF) test method, A326.3 (April 2017), states that “hard surface flooring materials suitable for level interior spaces expected to be walked upon when wet with water shall have a wet DCOF of 0.42 or greater when tested … as per this standard.” The […]
