Suggested Specifications for Lifetime Slip Resistance of Flooring

When we’re buying new automobile tires we’d like to know not only that the tires are good at the time of purchase, but that they will have a reasonably long lifetime for us. Michelin, for instance, offers models with mileage warranties (within a time limit) from 36,000 to 80,000 miles. When buying slip-resistant flooring, customers […]

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 […]

Germany’s DIN 51130 Slip Test: What’s it Good For?

In Europe a slip resistance test for flooring is prescribed by German Institute for Normalization (DIN) standard DIN 51130. A person wearing industrial-type treaded shoes walks, facing downslope, on a variable-angle ramp which has the flooring to be tested on it. The flooring is coated with motor oil. The walker (without holding the handrails) adjusts […]

SparkleTuff Outdoors on Level Surface and Stairs: 30-second video

The video below shows an outdoor level surface and stairs at a large mall, coated with transparent SparkleTuff™ Anti-Slip. A pedestrian walks down the stairs, which are partially wet from the previous day’s rain. With a material cost of about a dollar a square foot, SparkleTuff™ has excellent wet slip resistance by all respected test […]

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 […]

Making Your Stairs Safer

An important part of ensuring the safety of stairs is making sure the steps are clearly visible. This is especially true for commercial properties, but can also be crucial for private homes — particularly if the occupants are visually impaired to some extent. These outdoor stairs at a civic building are quite easy to see […]

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 […]
