What is the maximum reach for a 28-ft (8.5-m) ladder?

• A. First story roof
• B. Second story roof
• C. Third story roof
• D. Ground level

Answer: (B)

The maximum reach of a 28-foot ladder is typically designed to access the second story of a standard building. When estimating ladder reach, it's important to consider the angle at which the ladder is placed and the height of a typical story in a building, which is usually around 10 feet. Therefore, a 28-foot ladder, when positioned correctly at a safe angle, can effectively reach the roof area of the second story. For context, a first story roof is generally reachable with a shorter ladder, while a third story would exceed the capability of a 28-foot ladder, requiring a longer ladder. Ground level is below the reach of any ladder as it does not require elevation. Thus, the ladder's design and function confirm that its intended maximum reach aligns with accessing a second story roof.
