When calculating the total weight a ladder must support, which of the following should be included?

When calculating the total weight a ladder must support, it is crucial to include all potential weight it will bear during use. This means considering not only the weight of the user but also the weight of any tools or equipment the user may be carrying. Including the weight of tools is essential because they can significantly add to the overall load on the ladder, affecting its stability and safety.

By incorporating both the user's weight and the weight of the tools, you ensure that the ladder is rated to handle the entire load safely. This holistic approach to weight calculation helps prevent accidents or ladder failures, as the ladder needs to remain stable and secure under all circumstances.
