choose an option below

Explanation:

Portable ladders are required to have a clear label with their weight capacity (duty rating) on the side rail as a safe, official guideline. Testing by ascending and waiting for buckling is dangerous and not a proper method.

Answer:

Check the label posted on the side rail of the ladder to find its weight capacity or "duty rating".
