At what height must fixed ladders require a cage or ladder safety device?

Fixed ladders must include a cage or a ladder safety device when they extend 24 feet or higher. This requirement is stipulated by OSHA standards to enhance the safety of workers who use these ladders. The purpose of a cage or safety device is to prevent falls, which are a significant hazard in construction and maintenance tasks. Ensuring that these protective measures are in place reflects a commitment to workplace safety, as the risk of falling increases with the height of the ladder. Thus, the correct height threshold for requiring these safety features is 24 feet.
