Handwashing sinks may be interchangeable with prep sinks if what conditions are met?

Handwashing sinks are specialized fixtures designed specifically for handwashing, which is critical for preventing cross-contamination in food preparation environments. These sinks must be appropriately stocked with soap and disposable towels to ensure effective hand hygiene. When handwashing sinks have adequate soap and towels available, they can be used reliably for their intended purpose of maintaining food safety.

The other aspects of interchangeability, such as size or proximity, do not address the fundamental requirement for hygiene. While having hot water is another important consideration for handwashing, simply having hot water available does not guarantee that proper handwashing practices will be followed. Only when there is a consistent supply of soap and towels can a handwashing sink effectively fulfill its hygienic function. Thus, the availability of soap and towels is key in establishing whether handwashing sinks may be used interchangeably with prep sinks.
