To prevent trip hazards in the workplace, employers should ensure that work sites are kept clean and free from materials or equipment that could cause workers to slip or trip [1]. Passageways, traffic lanes, and exits should not be obstructed [2]. Lighting at the work site should be sufficient to allow work to be done safely 1, 7. Walking-working surfaces should be maintained free of hazards such as sharp or protruding objects, loose boards, corrosion, leaks, spills, snow, and ice [3].
