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 […]

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 […]

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 […]

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 […]

Slip Resistance Standard for Swimming Pools, Spas, Hot Tubs, Splash Pads, etc.

The National Sanitation Foundation (NSF), together with American National Standards Institute (ANSI) and National Standard of Canada (CAN) established a slip resistance standard for recreational water facilities. Formalized in NSF/ANSI/CAN 50 – 2019, the standard requires a wet Slip Resistance Value, SRV, of 40 or greater, measured using the pendulum slip resistance test method. Though […]

SDA Can Offer Foreign Insurance if Needed

As pointed out elsewhere in these pages, Safety Direct America has general liability and professional liability (Errors and Omissions) to cover our floor slip resistance testing work for clients located in the USA. However, we often do laboratory or field floor slip test work for foreign clients, sometimes on their own premises, e.g. in Canada […]

Detailed Information on Our Abrasive Anti-Slip Tapes

Occasionally a customer asks what the “grit size” is for our self-adhesive Safety Grip abrasive anti-slip tapes. The numbers are mostly irrelevant for reasons discussed below, but here they are together with their wet Pendulum Test Values (PTV): Standard Safety Grip is roughly equivalent to 60 grit abrasive paper: wet PTV = 71 (using TRL […]

A Review of Standards for Pedestrian Slip Resistance Testing

There are a number of floor slip test methods established by standards-setting organizations that assess pedestrian slip resistance. Here we’ll review the most widely known and current ones. They are distinguished by the devices used in the testing. Terms such as DCOF rating, coefficient of friction, slip coefficient, slip resistance rating, and friction coefficient all […]

Beware of Slippery Finished-in-Place Floors Installed by Clueless Contractors

Some floors are covered with premanufactured stuff, such as marble, granite or ceramic tiles, wood, or vinyl composite tile. Other floors are created in place — including epoxy, terrazzo, and concrete. Topical sealers added to premanufactured floors also constitute a finished-in-place surface — the pedestrian is not walking on the flooring, but on the sealer. […]

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 […]
