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.

Objectives:

  • The basics of pedestrian slip events
  • The imperfect requirements for walkway friction in codes and standards
  • Walkway friction tester (“tribometer”) methods, good and bad, in the context of litigation cases
  • Why tribometer testing methods need both reliability statistics and correlation to human slips
  • How to know when experts are using questionable methodologies
