How far must fixed ladders extend above landings?

Fixed ladders, especially in mining and industrial settings, must extend a minimum of 3 feet above the landing to ensure safety and provide adequate handhold for individuals using the ladder. This requirement is crucial as it allows workers to safely transition from the ladder to the landing without the risk of slipping or falling. The additional height offers a secure grip, making it easier to stabilize oneself when stepping off the ladder. This safety standard is in place to help prevent accidents that can occur if the ladder is not tall enough, ensuring a comfortable and safe entry or exit on elevated surfaces.
