Where is it appropriate to dispose of liquid waste such as mop water?

1. Service sink

2. Food preparation sink

3. Outdoor dumpster area

4. Hazardous waste container

The correct answer is: Service sink

Disposing of liquid waste, such as mop water, in a service sink is the appropriate choice because service sinks are specifically designed for the disposal of wastewater. Service sinks are typically found in commercial kitchens and are used for cleaning utensils, equipment, and, importantly, for disposing of liquid waste that may not be suitable for disposal in sinks designated for food preparation. This helps to prevent cross-contamination and ensures that food handling areas remain sanitary. Using a food preparation sink for disposing of mop water is inappropriate as it can introduce contaminants into areas where food is prepared, leading to potential foodborne illnesses. Outdoor dumpster areas are not suitable for disposing of liquid waste since they are meant for solid waste and may attract pests if liquids are added. Lastly, hazardous waste containers are designated for specific materials that are toxic or pose a safety risk when disposed of improperly, which does not apply to standard liquid waste like mop water. Thus, the service sink serves both a practical and hygienic purpose for the disposal of such waste.
