Man Trips on Protruding Carpet

This case involves a man who tripped and broke his leg on a protruding carpet upon exiting an elevator in the lobby of his apartment building in Colorado. The carpet was not affixed to the floor and is pulled up frequently for vacuuming and cleaning. The plaintiff alleges that the carpet posed a significant danger to the building’s residents, and that the landlord was negligent in allowing the carpet to remain unsecured.

Expert Witness Response E-016430

My area of expertise is gait (walking) and have testified in Ontario Civil courts regarding slips, trip, and fall biomechanics and kinesiology. Primarily, most of the work is related to tripping on uneven or elevated surfaces or obstructions on floor surfaces, so this case is certainly within my area of expertise. I have done work on slipping on carpeted areas in the past. The issues related to tripping on removable surfaces, like this carpet, are related to the weight, stiffness and radius of curvature to define how likely the carpet will rise above the floor level.
