Are two people allowed to work from a hook ladder?

In certain scenarios, two people can indeed work from a hook ladder, particularly under safe conditions and when proper regulations and guidelines are followed. Working from a ladder generally requires ensuring that the ladder is stable and secured, and having a second person can provide added support, particularly in tasks that involve handling tools or materials that may require a team effort.

It's important for both workers to be adequately trained in ladder safety and the specific operational procedures relevant to their tasks. Moreover, the tasks they are performing should not compromise safety—meaning both individuals should maintain the required three points of contact while on the ladder.

Understanding the context of the work is essential; in some specific situations, such as certain maintenance tasks or emergency services, additional personnel on a ladder could be standard practice as long as safety protocols are adhered to, ensuring the well-being of everyone involved.

Thus, while option A is the direct answer, it is always critical to consider the situational factors and applicable safety standards that guide ladder use.
