How long should a test strip be dipped in sanitizer solution to check the PPM?

• A. 5 seconds
• B. 10 seconds
• C. 15 seconds
• D. 20 seconds

Answer: (B)

Dipping a test strip in sanitizer solution for the appropriate duration is essential to accurately measure the parts per million (PPM) of the solution. The correct duration for dipping the test strip is 10 seconds, as this allows the strip to fully absorb the sanitizer and react with it, providing a reliable reading of the concentration level. This duration is based on standard practices for using test strips effectively, ensuring that the strip has enough time to interact with the sanitizer while avoiding over-saturation, which might lead to inaccurate readings. When the strip is dipped for too short a time, there may not be sufficient reaction to generate a clear and accurate result. Conversely, an extended dipping time could skew the results due to overexposure to the chemical. The specific recommendation of 10 seconds balances these factors to ensure that users can confidently assess the sanitizer's strength, ensuring proper sanitization practices are maintained in food handling environments like Taco Bell.
