Cleaning Chemicals and the Sandwich Bench
It is 2:45 pm after lunch service. You are asked to clean the sandwich bench before afternoon prep at 3:15 pm. You find an unlabelled spray bottle under the sink containing a clear liquid. A second bottle is labelled 'sanitiser' but the label is faded. The bench has just been used to make chicken sandwiches. You have 30 minutes, one clean cloth, and a queue of prep tasks. The chemical store is locked and the supervisor is in a meeting. Another student says the unlabelled bottle is 'probably just water' and starts to spray it on the bench.
1. What do you do immediately, and why is the unlabelled bottle a problem?

Stop the other student from spraying the unlabelled bottle. An unlabelled chemical is a hazard: it could be a cleaning agent, a sanitiser at the wrong concentration, or something not food-safe. Do not guess. Move the bottle away from food and the bench, and do not use it. The faded 'sanitiser' label is also a problem because you cannot confirm the product or its dilution. The correct action is to find a properly labelled, food-safe sanitiser, or ask the supervisor to identify the chemicals. Until then, clean the bench with a known food-safe detergent and hot water, then use a correctly labelled sanitiser if available. Record the issue and report the unlabelled bottle.
2. Describe the correct cleaning and sanitising sequence for the sandwich bench before prep.

Remove visible food debris and any equipment from the bench. Clean with hot water and a food-safe detergent to remove grease and residue, using a clean cloth. Rinse if required by the product instructions. Apply a food-safe sanitiser at the correct dilution and contact time, then allow it to air dry or wipe with a clean cloth as directed. Wash hands before and after. Do not use the same cloth for the bench and the floor. Keep chemicals away from food, and never store them in unlabelled containers. Once the bench is clean and dry, it is ready for prep.
3. The supervisor returns after prep has started. How do you raise the issue and what should happen next?
Read the worked answer
Raise it calmly and specifically: an unlabelled spray bottle was under the sink, a sanitiser label was faded, and another student tried to use the unlabelled bottle. Explain what you did instead: stopped its use, cleaned with food-safe detergent, and used a labelled sanitiser if available. Recommend the unlabelled bottle be identified or disposed of, labels be replaced, and chemicals be stored in a locked, labelled store away from food. Ask for the chemical safety information to be made available. Record the incident. The aim is to fix the system, not blame the other student, and to make sure the bench and food were not contaminated.
