What must be done if disinfectant becomes visibly contaminated?

• A. Dilute and reuse
• B. Replace the solution immediately
• C. Continue using after shaking
• D. Wait until the end of day

Answer: (B)

Disinfectants must stay uncontaminated to work effectively. When the solution is visibly contaminated, its active ingredients can be neutralized or microbes can accumulate, meaning it no longer reliably kills pathogens and can spread infection instead of preventing it. The correct action is to replace the solution immediately with a fresh batch prepared exactly according to the product’s directions, then dispose of the old solution properly and label the new one with the date. This keeps your tools and work environment sanitary. Diluting and reusing the contaminated mix isn’t safe because the concentration can fall below the required level. Shaking and continuing to use doesn’t remove the contamination or restore effectiveness, and waiting until the end of the day only increases the risk of cross-contamination.
