Why is it important to place gas sampling tubes correctly during fumigation?

1. To minimize labor costs

2. To ensure accurate measurements

3. To expedite the fumigation process

4. To comply with regulatory requirements

The correct answer is: To ensure accurate measurements

Placing gas sampling tubes correctly during fumigation is crucial to ensure accurate measurements of the concentration of the fumigant in the air. Accurate measurements are essential for several reasons. First, they help determine whether the fumigant is present in sufficient quantities to effectively control pests. Inadequate concentrations may lead to ineffective treatments, requiring repeat applications and escalating costs. Furthermore, accurate measurements help in evaluating the potential toxicity of the fumigant to humans, animals, and the environment. This is vital for ensuring safety and taking necessary precautions to protect workers and nearby communities. By properly positioning the gas sampling tubes, fumigators can monitor the gas levels effectively and make informed decisions throughout the fumigation process. While minimizing labor costs, expediting the fumigation process, and complying with regulatory requirements can be relevant factors in overall fumigation practices, they do not directly address the critical need for precision in measuring fumigant concentrations during the operational phase.
