By how much must fixed ladders project above landings?

Fixed ladders must project a distance of 3 feet above the landing to ensure safe access and egress for mine personnel. This height is established to provide an adequate handhold for users when they are transitioning from the ladder to the landing or vice versa. The additional height helps to minimize the risk of slipping and falling during this critical movement, which can often occur when a person is climbing up or down a ladder.

This requirement is part of safety regulations aimed at preventing accidents in potentially hazardous mining environments, where maintaining secure footing and handholds is essential for the safety of workers. The 3-foot projection standard is recognized in safety guidelines to ensure proper design of fixed ladders across various industries, specifically in settings where safety is paramount.
