What is the minimum load capacity defined for the outermost rung of the outermost fly section at maximum horizontal extension with stabilizers deployed?

• A. 150 lbs
• B. 200 lbs
• C. 250 lbs
• D. 300 lbs

Answer: (C)

Focus on the load the ladder must safely carry at its extreme reach. When the ladder is fully extended horizontally with the stabilizers out, the outermost rung of the outermost fly section bears the greatest bending and user load during climbs or rescue actions. The standard sets a minimum load capacity for that rung at 250 pounds to ensure a person (with gear) can safely stand or work there without risk of failure, while still accounting for dynamic forces that occur during operation.

Lower numbers like 150 or 200 pounds wouldn’t provide enough safety margin for a real rescue scenario, and while a higher rating such as 300 pounds would be acceptable, the question asks for the minimum required. So 250 pounds is the correct baseline minimum.
