Question: 1 / 400

When is it appropriate to check the concentration of Quat solution?

Once a day

Before each use

Checking the concentration of Quat solution before each use is crucial for ensuring that the solution is effective in sanitizing surfaces and food preparation areas. Quaternary ammonium compounds (Quat) are used for their antimicrobial properties, and their effectiveness depends on maintaining the correct concentration. If the concentration is too low, it may not effectively kill harmful bacteria, leading to potential food safety risks. Conversely, if it’s too high, it can be hazardous and damage surfaces.

Regularly testing the concentration just before the solution is utilized guarantees that employees are always working with a solution that is potent enough to meet health and safety standards. This step is essential for maintaining a safe environment, particularly in a food service setting like McDonald's, where cleanliness and sanitation play a key role in operational success and customer safety.
