OSHA housekeeping rules (29 CFR 1910.22) state that "all places of employment, passageways, storerooms, and service rooms should be kept clean and orderly and in a sanitary condition." The regulation makes specific mention of keeping floors clean and dry: "To facilitate cleaning, every floor, working place, and passageway shall be kept free from protruding nails, splinters, holes, or loose boards." The regulation also says that "aisles and passageways shall be kept clear and in good repair."
