Commodity Fumigation License Practice Exam

What potential issue arises when transporting fumigants in closed vehicles?

1. Increased chance of gas leakage

2. Risk of combustion

3. Excessive pressure build-up

4. Exposure of the driver to chemicals

The correct answer is: Increased chance of gas leakage

The primary concern when transporting fumigants in closed vehicles is the potential for excessive pressure build-up. Fumigants can release gases that expand when heated, and if the vehicle is sealed, the pressure inside can increase significantly. This can lead to dangerous situations such as ruptures, which may not only spill the fumigants but also create hazardous environments both inside the vehicle and externally. While there are other risks associated with fumigant transportation, excessive pressure is especially critical because it directly relates to the material properties of the fumigants and the conditions found in a closed space. Proper ventilation or temperature control measures must be in place to mitigate this risk effectively, ensuring the safety of the driver and others around. Understanding this aspect of fumigant transportation is vital for compliance with safety regulations and for the overall management of hazardous materials.
