Slip Resistance Measurement

Why Measure Slip Resistance?

To prevent slips and falls:

For Compliance:

After an Incident or Accident:


It is important to be able to quantify the slip resistance of walking and working surfaces. A good slip and fall prevention program will make use of measurements as a way to prioritize risks, track progress of control measures, and provide a way to control the quality of floor care.

For litigation of slip and fall cases, good measurements of the slip resistance of a surface can make or break a case.  It takes more than a certain number to make a judgment about a surface. It takes knowledge of the key factors involved in slips and falls, understanding of measurement methods and equipment, and the ability to pick out the key variables in a given situation and report on them.

David Natalizia has performed hundreds of real-world floor and walkway evaluations, and has testified in court in slip and fall cases. David serves as secretary of committee f13.10 on traction in the American Society of Testing and Materials committee F13, Pedestrian/Walkway safety and footwear.

We perform slip resistance measurements using the finest measurement device available, the English XL Variable-Incidence Tribometer. The ASTM F1679 standard applies to this device, as one of only two ASTM recognized test methods for wet conditions. David Natalizia is certified by the International Safety Academy in slip resistance measurement, with the CXLT (Certified XL Tribometrist) designation. Slip resistance testing can also be performed using several other ASTM-recognized methods.

Beyond slip resistance, we are equipped to measure and report on all aspects of walkways and stairs for pedestrian safety.
