When using an extension ladder, how many feet must it extend past the platform?

When using an extension ladder, it is crucial for safety that the ladder extends at least 3 feet beyond the platform or landing. This extension provides a secure handhold for the user when transitioning onto or off of the ladder. By having this additional length, the ladder ensures stability and reduces the risk of slipping or losing balance as a person steps on or off the platform. This guideline is widely recognized in safety standards and best practices for ladder use to prevent accidents while working at height.
