Question: 1 / 400

How many feet must the side rails of a portable ladder extend above the landing's surface?

Two feet

Three feet

The correct answer is that the side rails of a portable ladder must extend a minimum of three feet above the landing's surface. This requirement is crucial for safety, as the extension provides stability and a secure grip for the individual using the ladder. When a ladder extends three feet above the landing, it enables the user to maintain three points of contact when transitioning onto or off of the ladder, reducing the risk of falls or slips.

Ladders are frequently used in various settings, including construction sites and maintenance tasks, making compliance with safety standards essential to prevent accidents. By ensuring that the ladder extends adequately above the landing, users can safely grasp the railing at a higher position, which significantly enhances safety during the transition process. This standard aligns with general safety guidelines in ladder usage, highlighting the importance of proper ladder height in preventing workplace injuries.
