Commodity Fumigation License Practice Exam

A railcar that cannot be made airtight can be fumigated under a tarpaulin. Is this true or false?

1. True

2. False

3. Only under special circumstances

4. Only if sealed properly

The correct answer is: True

The statement that a railcar that cannot be made airtight can be fumigated under a tarpaulin is true. Fumigation requires containment of the gas used to ensure it can effectively permeate the target area and eliminate pests. When dealing with a railcar that lacks the ability to be sealed tightly, using a tarpaulin can create an enclosed environment that minimizes gas escape. This method helps in maintaining an adequate concentration of the fumigant within the designated space, allowing for successful pest control. While ensuring that the tarpaulin is secured to reduce leaks is vital, the core principle here is that tarpaulins provide a feasible alternative method of containment when traditional airtight sealing isn't possible. It acknowledges practical approaches in commodity fumigation where flexibility is required to ensure efficacy in varied situations.
