How can an employee be certain the chemical sanitizer being used in the manual sink is of correct strength?

Using a test kit to measure the concentration of a chemical sanitizer is the best way for an employee to ensure that the sanitizer in the manual sink is of the correct strength. A test kit allows for precise measurements and verification, ensuring that the sanitizer concentration falls within safe and effective levels for sanitizing surfaces. This method provides quantitative data rather than relying on subjective assessments or assumptions.

While following directions on the chemical product is important for initial mixing and preparation, it doesn't guarantee that the solution remains at the proper strength after being diluted in water or used over time. Simply adding water until the color appears right is not a reliable measure because the visual appearance of the solution can be misleading. Relying on the manager for assistance can be helpful, but it doesn't directly ensure that the employee is checking the concentration themselves in real-time. Using a test kit empowers employees to take direct responsibility for food safety practices.
