How is the maximum work height determined?

The maximum work height is determined by considering the combination of your height, your reach, and the highest standing level of the ladder. This method ensures a comprehensive assessment of how high you can safely work while using the ladder. Personal height and reach account for the additional distance you can extend when safely working from a standing position on the ladder, which is critical for tasks that require precise placement or maneuvering at height.

By focusing solely on the ladder's height or the manufacturer's specifications, one would miss crucial personal factors that impact safety and reach, which could lead to trying to work beyond what is physically safe or feasible. Manufacturers typically provide guidelines that relate to the ladder's safe use; however, personal assessment plays a vital role in determining maximum work height. Thus, integrating all these elements provides a more accurate and safe calculation for maximum work height.
