What can be used to join and seal the edges of two tarps when fumigating structures?

In fumigation practices, particularly when sealing the edges of tarps around a structure, it is essential to use materials that can provide an effective barrier against gases and prevent leaks. Clamps are an ideal choice because they can securely hold the tarps together without damaging the material, ensuring an airtight seal. This helps maintain the integrity of the fumigation process and allows for effective pesticide retention.

While alternatives such as tape can be used, it might not provide as sturdy a hold or may not be resistant to the conditions present during fumigation. Staples can puncture the tarp, leading to potential leaks. Glue might also not create a reliable seal in all conditions and could result in adhesive breakdown due to exposure to chemicals or environmental factors. Therefore, clamps are the most effective and reliable method for joining and sealing the edges of tarps during fumigation.
