How is it that on the same slip and fall claim, one expert opines the floor is safe for ambulation, and another states the floor is slippery and caused the fall? The answer is not so obvious, but the scenario is very common, creating liability when there may be none. Experts should be trusted, but at times, even they are unknowingly in the dark. Slips, trips, and falls account for over 25% of all injuries across all industries. Slip and fall litigation is second only to vehicle collisions, creating a high demand for experts in the slip and trip arena to provide attorneys and insurance companies with an efficient resolution for their clients. However, most approaches to this discipline will not stand up to the rigors of litigation. Different tribometers yield different COF values for a given surface, making it difficult for experts to know which standards and methodologies to follow.
