A barricade line needs posts every 30 feet along a 180-foot edge, including both ends. How many posts are needed?
Correct Answer
A) 7 posts.
One hundred eighty feet divided by 30 feet gives 6 spaces; including both ends requires 7 posts.
Why This Is the Correct Answer
One hundred eighty feet divided by 30 feet gives 6 spaces; including both ends requires 7 posts.

Option D: 9 marked posts.
9 marked posts. is above the supported result for fall protection layout calculation; it likely adds a step the rule does not support.
