List the correct order for placing shoring equipment in a trench. Starting at the top move to the bottom of the trench and ____________ to remove it.

• A. Invert
• B. Reverse
• C. Remove top to bottom
• D. Undo from above

Answer: (B)

When working with trench shoring, installation is done from the top down so each section supports the walls as you go. To remove safely, you reverse that sequence: take the bottom pieces out first and work upward. This bottom-to-top removal keeps the trench supported as you progressively withdraw the shoring, reducing the risk of a cave-in while workers are still inside. Removing from the top down would remove the last line of support first and could allow the walls to fail. So the best approach is to reverse the installation order during removal.
