Extension ladders up to 36 feet should have a minimum of a ___ overlap between sections when extended.

• A. 2'
• B. 3'
• C. 4'
• D. 5'

Answer: (B)

For extension ladders that reach lengths of up to 36 feet, ensuring safety is paramount, and one key safety guideline involves the overlap between sections when the ladder is extended. A minimum of 3 feet of overlap is required to provide adequate stability and strength. This overlap helps maintain the ladder’s integrity while in use, reducing the risk of the sections separating or collapsing under weight. It ensures that the ladder can safely support the user and any tools or materials being used during work at height.

Ladders with insufficient overlap may not distribute weight properly, increasing the risk of accidents. Thus, adherence to the guideline of a minimum of 3 feet overlap not only contributes to the user’s safety but also aligns with industry standards and best practices for ladder safety.
