By how much must a ladder extend above the working surface?

1 foot
2 feet
3 feet
4 feet

The correct answer is: 3 feet

The requirement for a ladder to extend above the working surface is essential for ensuring safety when workers are exiting or entering a structure. Extending the ladder at least 3 feet above the working surface provides a secure handhold, helping to prevent falls and offering extra stability while transitioning between the ladder and the platform. This extension enhances the user's grip on the ladder, allowing them to maintain balance and control as they step on or off. By ensuring that a ladder extends at least 3 feet above the point of access, it meets safety guidelines and standards commonly upheld in workplace and construction environments, reducing the risk of accidents associated with improper ladder use. This specific measurement is often included in safety regulations to standardize ladder usage and promote safe practices among workers.
