What must be provided in all culinary and pot/dish washing sinks?

In culinary and pot/dish washing sinks, the presence of air breaks is essential. An air break is a physical separation between the water supply and the sink's drainage system, preventing backflow and potential contamination of the water supply. This is crucial in ensuring food safety and hygiene standards are maintained in a kitchen environment.

Air breaks help to keep the culinary water supply safe from exposure to waste materials or contaminants that could flow back into the clean water source. This is particularly important in settings like commercial kitchens or food service operations where proper sanitation practices are paramount.

Other options, while they may serve important functions in food safety and cleanliness, do not fulfill the specific requirement for preventing backflow in washing sinks. For example, handwashing stations are necessary for proper hygiene among food workers but are separate facilities from culinary and pot/dish washing sinks. Similarly, thermometers are important for monitoring food temperatures, and water filters improve water quality, but they do not address the critical function of air breaks in preventing backflow in sink systems.
