When applying an internal treatment solution to a utility pole, where should you start?

• A. Start at the lowest bore hole and work up
• B. Start at the highest bore hole and work down
• C. Start at the middle and work outward
• D. Start at any bore hole you choose

Answer: (A)

Start at the lowest bore hole and work upward because you want the treatment to saturate the pole from bottom to top. Filling from the bottom uses gravity to push the solution upward, pushing any air upward and out through the higher holes as you progress, which helps ensure there are no air pockets and that the interior is fully saturated. Starting at a higher hole or the middle can leave the lower parts partially untreated and trap air, making the treatment less effective.
