What 3 things need to be provided at a hand wash sink by law?

By law, a hand wash sink must provide three essential features: a constant supply of hot and cold running water, soap for hand washing, and disposable paper towels or a hand-drying device. Additionally, the sink should be easily accessible and designated specifically for hand washing to ensure proper hygiene practices are followed. These requirements help prevent the spread of pathogens in food handling and healthcare environments.
