What is the minimum temperature for drinkable warm water at a hand washing sink?

The minimum temperature for drinkable warm water at a handwashing sink is generally accepted to be 100°F. This temperature is warm enough to facilitate effective handwashing by helping to dissolve soaps and enhance the cleaning process, making it easier to remove dirt, grease, and pathogens from the hands.

Water at this temperature ensures a comfortable experience for the user, encouraging proper handwashing behavior, which is crucial in preventing foodborne illnesses and maintaining hygiene in food-related operations. Higher temperatures, while effective for cleaning, may pose a risk of scalding or discomfort if they exceed personal tolerance.

Maintaining a warm water temperature of at least 100°F is essential in food safety practices, as it promotes consistent and effective handwashing that is critical in foodservice environments.
