What is the minimum floor lap of the tarpaulin required around all sides of the load?

  1. 12 inches

  2. 18 inches

  3. 24 inches

  4. 30 inches

The correct answer is: 18 inches

The minimum floor lap of the tarpaulin required around all sides of the load is crucial for ensuring effective fumigation. A floor lap of 18 inches is an established standard that provides sufficient overlap to create a secure seal around the fumigated area. This overlap helps contain the fumigant within the target area, preventing leakage and ensuring that the fumigation process is effective in treating the commodities. An adequate lap is essential for maintaining the integrity of the fumigation process, as it minimizes the potential escape of the fumigant, which is critical for achieving the desired pest control results. Additionally, the 18-inch overlap is practical enough to allow for proper tarpaulin placement and adjustment during the fumigation setup, without introducing unnecessary complexity or complications.
