Tangled cords are one type of clutter that can turn an office walkway into a harrowing obstacle course. It's almost as if cords tangle themselves. Then they go chameleon, blending into floors, carpets and walls, unnoticed until someone trips over them. According to OSHA, slips, trips and falls -- many which can be caused by tangled cords -- constitute the majority of general industry accidents, as well as 15 percent of all accidental job-related deaths. A surface cable raceway -- a plastic guard that shields cords, wires and cables running across walkways -- can not only protect cables and keep them untangled, but also alert people to their presence in walking spaces.
