Which of the following is NOT one of the CSA ratings for ladders?

Light duty
Heavy duty
Extreme duty
Medium duty

The correct answer is: Extreme duty

The CSA (Canadian Standards Association) ratings for ladders categorize them based on their intended use and the load capacity they can support. The primary classifications in these ratings are usually light duty, medium duty, and heavy duty. These ratings help users select the appropriate ladder based on the tasks they need to perform and the weight they expect the ladder to support safely. In this context, the term "extreme duty" is not recognized as one of the CSA ratings for ladders. The CSA does not specify a classification for "extreme duty," making it a non-standard designation in ladder ratings. This is why "extreme duty" stands out as the option that does not fit within the established categories. Therefore, the correct response is that "extreme duty" is NOT one of the CSA ratings for ladders, aligning with the understanding of the standards used in ladder manufacturing and categorization.
