We’ve all heard the old adage, “Fool me once, shame on you; fool me twice, shame on me.” The Tile Council of North America (TCNA), who reportedly is “in partnership” with at least one of America’s largest tile manufacturers, spent almost two decades promoting the misinformation that the ASTM C1028 static coefficient of friction (SCOF) […]
How to Get The Slip and Fall “Expert” Witness Testimony from an English XL VIT and Brungraber Mark IIIB User Thrown Out of Court
Slip and fall “expert” witnesses in the United States typically use either the English XL Variable Incidence Tribometer (VIT) or the Brungraber Mark IIIB, which is incredibly frightening considering that neither of these two instruments have a published, peer-reviewed test method in any country on earth, and both (the English XL and Brungraber Mark II, […]
ASTM E303-22 Revolutionizes Floor Slip Resistance Testing in the USA
Floor slip resistance tests in the USA have historically been written by the members of the ASTM F13 committee. Comprised mostly of expert “liars for hire” that exclusively work for slip and fall attorneys, and representatives of the flooring industry, these tests have been based on either no science, or very little shady science. The […]
ADA Slip Resistance Requirements
The Americans with Disabilities Act (ADA) requires that floors accessible to disabled persons be “slip-resistant”, but does not define what that means. Apparently it’s up to property owners and the courts to decide. But there is a reliable way of assessing slip resistance that is recognized the world over to help comply with ADA slip […]
Can a Floor be Too Slip Resistant?
As floor slip resistance testing experts with decades of experience, we’re sometimes asked if a floor can be too slip resistant, usually by someone who is trying to sell a flooring that is likely too slippery for a particular application. The answer, put simply, is no. There is no such thing as a floor that’s […]
Cleaning Anti-Slip Floors
After installing a tile or other type of flooring that has great slip resistance, or after applying an anti-slip floor coating with great slip resistance on top of a slippery floor (like SparkleTuff™ Anti-Slip Floor Coating), you’ll find that dragging a dirty mop across the floor may no longer be sufficient to get the floor […]
Slippery Epoxy Garage Floors – SparkleTuff™ Anti-Slip Floor Coating to the Rescue
Our transparent abrasive anti-slip floor coating, SparkleTuff™, has been applied to hundreds of different kinds of floors, and we have yet to find a surface to which it won’t adhere. However, based on the number of frantic phone calls we get, home garage floors that have been newly coated with epoxy seem to be the […]
Pool Deck Slip Standard would Create Jobs for Lawyers
A swimming pool deck slip resistance standard is proposed that if adopted will cause hundreds of millions of dollars of misspent investment; lead to thousands of slip and fall accidents, many with life-changing injuries; cost hundreds of millions in medical bills and other losses; and lead to far too many premature deaths due to injuries […]
Safety Direct America Calibrates Pendulum Skid Testers from Far and Wide
Like any scientific or engineering instrument, the pendulum skid tester (also sometimes called the British pendulum or pendulum slip tester) should be calibrated at least once annually. Safety Direct America, a subsidiary of Sotter Engineering Corporation, is the leading calibrator of pendulum skid testers in the Americas. Alignment of the vertical shaft (level bubble) and […]
2022 Revised ANSI A326.3 Has Five Situation-Specific DCOF Minimums — And Crucial Caveats
In February of 2022, the American National Standards Institute (ANSI) issued a revised version of their “Test Method for Measuring Dynamic Coefficient of Friction of Hard Surface Flooring Materials.” Situation-specific recommended minimum DCOF values range from 0.42 to 0.55. As in previous versions, this one has important caveats. E.g., “The specifier shall determine materials appropriate […]
