You must have hand sinks conveniently located in all of the following areas except:

Hand sinks are essential in food handling environments to ensure proper hand hygiene among staff. They are required to be conveniently located in areas where food is prepared, served, or where staff may need to wash their hands frequently to prevent cross-contamination.

In restrooms, hand sinks are mandated to promote sanitation and hygiene after using the facilities. In the prep area, their presence allows staff to wash their hands before and after handling food, which is critical for food safety. Having them near the warewashing area is also important because employees can wash hands after handling dirty dishes, ensuring that they do not transfer contaminants back to clean areas.

A mop sink, however, is primarily designed for cleaning tools and equipment rather than for hand washing. While it is important to have washing stations for cleaning purposes, they do not serve the same hygiene functions as hand sinks for food handling. Therefore, having hand sinks near a mop sink is not necessary, as it does not align with the direct needs of food safety related to hand hygiene.
