VIEW CLE Accreditation by State

Program Overview

The past 10 years have brought significant advances in the field of reliable walkway slip analysis. At the same time, the inertia of decades of questionable analysis methods has not been overcome. Many “experts” still rely upon these questionable methods. This presentation, which features numerous case studies, takes an in-depth look at methodologies, research, standards, and practical applications of tribometer testing. A brief review of litigation considerations will be discussed as well. a06233af29bd77c60be910f30c9ce724.png
