What are “indicator strips” used for in the fumigation process?

• A. To assess the temperature of the fumigation area
• B. To monitor and confirm the presence of fumigants
• C. To measure humidity levels during fumigation
• D. To track the duration of exposure

Answer: (B)

Indicator strips are specifically designed to monitor and confirm the presence of fumigants during the fumigation process. These strips are treated with a chemical that changes color or provides a visual indication when exposed to certain gases, helping applicators verify that the designated fumigants are effectively present in the environment. This is crucial for ensuring that the fumigation is successful, as it allows professionals to confirm that the necessary levels of the fumigant are being maintained throughout the treatment period. In contrast, other options focus on different aspects of the fumigation process. For example, assessing temperature or measuring humidity are important but are typically monitored using separate tools or instruments designed specifically for those parameters. Similarly, tracking the duration of exposure is an operational aspect of fumigation management rather than something that would be indicated by chemical reaction in indicator strips. Thus, the use of indicator strips specifically serves the important function of monitoring fumigant presence, making option B the correct choice.
