Commodity Fumigation License Practice Exam

What is the purpose of using high range detector tubes?

1. To measure humidity levels

2. To detect worker safety levels

3. To confirm fumigant levels

4. To determine ambient temperature

The correct answer is: To confirm fumigant levels

The purpose of using high range detector tubes is to confirm fumigant levels. These detector tubes are specifically designed to measure the concentration of various fumigant gases in the air. By providing accurate readings of the fumigant levels present in the environment, they play a crucial role in ensuring safety during fumigation operations. In the context of fumigation, it is essential to monitor the concentration of fumigants to validate that they are applied at effective levels for pest control while also ensuring that they do not exceed safety thresholds that could pose a risk to workers or the environment. High range detector tubes enable operators to quickly assess fumigant levels and make informed decisions regarding safety protocols and operational procedures. Other options address aspects not related to the core functionality of high range detector tubes: measuring humidity levels pertains to moisture content, detecting worker safety levels involves monitoring exposure to hazardous substances, and determining ambient temperature focuses on climate conditions rather than gas concentration.
