What is an appropriate action if a three-compartment sink is not functioning?

Using a clean and sanitized bucket for washing is appropriate when the three-compartment sink is not functioning. This method allows for maintaining proper hygiene and sanitation standards even when the designated washing facility is temporarily unavailable. By utilizing a sanitized bucket, you can create a makeshift solution to wash dishes while ensuring that the food contact surfaces remain safe and free from contamination.

This practice is especially important in food service environments like Jack In The Box, where maintaining the safety and cleanliness of utensils and equipment is critical for preventing foodborne illnesses. The other options do not provide an adequate method for ensuring food safety. Skipping dishwashing entirely compromises hygiene, using a two-compartment sink does not allow for proper sanitization if there's no third compartment for the rinse, and rinsing dishes with only hot water does not eliminate food residues or sanitize them effectively.
