Here's one thing that can't be used to create, bind or shred a document, yet can be found in every office in the world: floors. Just like standard office tools, floors can be dangerous if not properly maintained. A slick, cluttered or dimly lit walkway is an invitation to a fall, which OSHA cites as the most common cause of disabling injuries sustained on the job. Office floors should be cleaned regularly and cleared of any loose material -- including frayed carpet or rugs. When navigating the office, workers should act like drivers: They need to keep their eyes on the road (in this case, the floor).
