The maximum allowed height for a step ladder is how many feet?

The correct answer indicates that the maximum allowed height for a step ladder is 20 feet. This height is established by safety guidelines and regulations to ensure safe usage practices when working at elevated heights. The design and stability of a step ladder are optimized for this maximum height, helping to prevent accidents and ensuring that users can maintain a safe center of gravity while working.

When using ladders, it's crucial to adhere to these height limitations, as going beyond them can increase the risk of tipping over or losing balance. The shorter options, like 15 feet, do not fully utilize the possible height for specific step ladders, while the higher options such as 30 and 40 feet exceed established safety standards, making them unsuitable for this category of ladder. Understanding these guidelines is essential for maintaining workplace safety in cabinet, millwork, and finish carpentry tasks.
