What is critical about the water used in hand washing stations?

The water used in hand washing stations is critical because it should be hot and drinkable. Hot water is essential for effectively removing food particles, grease, and pathogens from hands, making the handwashing process more effective. The temperature helps to break down oils and residues that can harbor bacteria, thus ensuring that hands are clean and sanitary.

Additionally, the water needs to be drinkable, which means it must meet safety and health standards set for potable water. This ensures that any potential contaminants in the water don't pose additional health risks. Overall, using hot, drinkable water contributes to proper hygiene practices in food service environments, which is crucial for preventing foodborne illnesses.
