What does the ladder's duty rating indicate?

• A. Maximum safe load capacity of the ladder
• B. Weight of the ladder itself
• C. Manufacturer maximum use height
• D. Recommended user age

Answer: (A)

The ladder’s duty rating represents the maximum safe load it can carry in use. That total includes your body weight plus any tools or materials you’re carrying while on the ladder. This rating is what guides you to choose a ladder that won’t fail under the expected load. It isn’t about the ladder’s own weight, nor about how high you can reach, nor about the user’s age. For example, if you weigh 180 pounds and carry 40 pounds of tools, you’d want a ladder rated for at least 220 pounds. If the load exceeds the rating, the ladder isn’t safe to use. Always pick a ladder with a duty rating above your expected total load and inspect the ladder before climbing.
