Warning signs and information signs are essential equipment for the cleaning team in public utility buildings. A wet floor carries a risk of falling and consequently getting injured. To prevent this, safety signs are used. They facilitate order maintenance and ensure the safety of people moving around in rooms where cleaning takes place. A yellow sign reading "Caution Slippery" or with the inscription "Warning! Slippery Floor", popularly referred to as a cone, is encountered in such facilities as schools, health care facilities, large stores, office buildings, and other public facilities.
Warning boards and information boards are an essential piece of equipment for the cleaning crew in public buildings. These ensure safety for persons moving around the premises where the cleaning is done. Such boards are used in schools, health care facilities, supermarkets, office buildings and other public facilities.
