Food & Water Sanitation Signs

Food and water sanitation signs identify safe and unsafe sources of water. Signs posted at safe water sources inform employees in large lettering that the water is drinkable. Signs posted at unsafe water sources inform employees that the water is non-potable and is not to be used for drinking, washing or cooking. Both types of signs often include universal pictograms that quickly communicate if the water is safe or unsafe. Signs also use bright, contrasting colors to increase visibility.
