550 The Changing World of Slip-and-Fall Analysis
Pedestrian fall incidents are frequently alleged to be caused by a “slippery” walkway surface.
Building codes, safety codes, and accessibility regulations require ad
equate walkway “slip resistance” without specifying how this is to
be confirmed. Demonstrating that a walkway surface provides sufficient (or insufficient) tracti
on is a complex task – requiring expertise and (where appropriate) the use of a
tribometer for traction measurement. The past five to ten years
have seen major advances in the scientific foundations for tribometry,
through correlation of tribometer measurements to actual human slip e
xperiences – and this is slowly advancing the
“standard of care” for slip-and-fall analyses.
