Why is it important to stack commodities on pallets before tarp fumigation?

  1. To minimize exposure to moisture

  2. To facilitate easier removal later

  3. To allow air circulation along the floor

  4. To save space in storage

The correct answer is: To allow air circulation along the floor

Stacking commodities on pallets before tarp fumigation is crucial primarily because it allows for air circulation along the floor. This is essential for effective fumigation because air circulation helps ensure that the fumigant can evenly distribute throughout the entire area and reach all surfaces of the commodities being treated. When commodities are placed directly on the ground, there is a risk of moisture absorption from the soil or floor, which could hinder the fumigation process and potentially lead to uneven treatment. By elevating the goods on pallets, airflow is enhanced, which can also help regulate temperature and humidity levels under the tarp, further promoting the efficiency of the fumigation process. Furthermore, proper circulation can help prevent the buildup of toxic gases, ensuring a safer environment for both the fumigator and the commodities. Overall, these considerations make air circulation a key reason for stacking commodities on pallets prior to fumigation.
