Never try lifting anything that is too heavy for you. Use either a mechanical lifting device designed for that purpose, or get assistance from a co-worker. Use correct lifting procedures when lifting heavy objects of any size. Read the label on office products as many are toxic or flammable and can cause skin irritations or respiratory problems. Keep the desk drawers shut unless you are actually using them.
Open drawers are obstacles to traffic and are easy to trip over.
Guards are required on all fans and heating units within 7 feet of the floor or working surfaces. The guard must not have any openings larger than one-half inch. Open no more than one drawer of a file cabinet at a time. Drawers should be closed when not in use. Always load file cabinets starting from the bottom drawer.
