Accident Investigation Expert Witness On Slip & Fall Litigation

In The Concept of the Coefficient of Friction in Slip and Fall Litigation accident investigation expert witness Melvin M. Friedlander, P.E., writes:

When a person enters litigation, because of an injury from a slip and fall accident, the slipperiness of the surface becomes a major factor in the matter before the court. The slipperiness of the surface is measured by a dimensionless ratio called the coefficient of friction or COF. The COF is the surface force, generated by a pedestrian, in the walking direction, divided by the weight of the pedestrian. As an example, a 200 pound pedestrian generating a 100 lb surface force will have a COF equal to 0.50
