What is the minimum circumference for poles to apply MITC Fume?

• A. 16 inches
• B. 16 inches or greater
• C. 12 inches
• D. 20 inches

Answer: (B)

When applying MITC Fume, you need a pole size large enough to seal and contain the fumigant so it treats the wood evenly. The circumference around the pole is the size that matters for fitting the application setup and preventing gas from leaking. The minimum circumference that meets the requirement is 16 inches, and any pole with a circumference of 16 inches or greater is eligible for treatment. If the pole is smaller than 16 inches, the seal won't hold properly and the fumigant may not reach all sides of the wood. A larger circumference, like 20 inches, is fine, but the question is about the smallest acceptable size, which is 16 inches or more.
