Commodity Fumigation License Practice Exam

What should be done if a commodity is wrapped in an impermeable material?

1. Remove the material completely

2. Open the non-permeable wrapper or container

3. Wait for the material to degrade

4. Leave the material as it is

The correct answer is: Open the non-permeable wrapper or container

When dealing with commodities wrapped in impermeable materials, it is crucial to allow for the effective penetration of the fumigant. By opening the non-permeable wrapper or container, one permits the fumigant to reach the pests that may reside within the commodity. This action is essential because fumigation relies on the gaseous form of the pesticide to diffuse into the surrounding environment where pests are present. If the material remains sealed, it effectively creates a barrier that prevents the fumigant from doing its job, potentially allowing pests to survive. Therefore, opening the wrapper or container ensures that the fumigation process can occur efficiently and effectively, leading to successful pest control. Removing the material completely might expose the commodity to the environment before the fumigation process begins, increasing the risk of reinfestation or contamination. Waiting for the material to degrade is an ineffective strategy as it does not facilitate pest control. Leaving the material as is would inhibit the necessary fumigant penetration, jeopardizing the entire fumigation effort.
