A worker stands with both feet on the top step of a ladder while painting. What has he done incorrectly?

Standing on the top step of a ladder is a safety violation because it significantly increases the risk of falling. Ladders are designed with safety standards that prohibit standing on the top step, as it does not provide adequate support and stability. This guidance is in place to help prevent accidents, as the top step does not allow for a secure center of gravity, which is crucial for maintaining balance. By following ladder safety guidelines, workers can avoid potential hazards associated with leaning or reaching too far while elevated, which can lead to serious injuries.

While choosing a taller ladder, securing the ladder, or disconnecting power sources are also important safety considerations, they do not directly address the immediate danger posed by standing on the top step of the ladder itself.
