Commodity Fumigation License Practice Exam

What is the minimum diameter required for sand or water snakes to seal the tarp to the floor?

1. 2 inches

2. 3 inches

3. 4 inches

4. 5 inches

The correct answer is: 3 inches

The minimum diameter required for sand or water snakes to effectively seal the tarp to the floor is crucial for ensuring that the fumigation space maintains proper integrity during the fumigation process. A diameter of 3 inches is typically sufficient to create a tight seal, which helps prevent gas escape and maintains the efficacy of the fumigants being used. Using a smaller diameter would likely result in less effective sealing, leading to potential gas leakage and compromised fumigation performance. Conversely, opting for a diameter larger than 3 inches could lead to unnecessary material use and may not provide additional sealing benefits. Therefore, 3 inches strikes a balance between effectiveness and practicality in sealing tarps during fumigation operations.
