What must a dishwashing sink and a food preparation sink not include?

A dishwashing sink and a food preparation sink must not include concealed overflows. The reason for this requirement primarily revolves around health and safety considerations within food service environments.

Concealed overflows can create hidden areas where debris, bacteria, or other contaminants can accumulate, making it difficult to maintain proper sanitation. Visible overflows, in contrast, allow for easier monitoring and cleaning, ensuring that any water that may overflow is promptly addressed without risking contamination of food preparation surfaces or dishes.

This design consideration helps promote hygiene and prevents cross-contamination, ultimately supporting food safety standards. By eliminating concealed overflows, facilities can better manage cleanliness and maintain compliance with regulations designed to protect public health.
