What is the minimum perpendicular space required between fixed ladder rungs and any obstruction behind the ladder?

The minimum perpendicular space required between fixed ladder rungs and any obstruction behind the ladder is 7 inches. This standard ensures safety and accessibility for users. The 7-inch clearance allows enough space for a person’s foot to land securely on the rung without being obstructed by items or surfaces behind the ladder, reducing the risk of slips, falls, or accidents. This safety specification is crucial in installation guidelines and building codes to maintain safe conditions when using fixed ladders in residential or commercial settings. Having adequate clearance behind the ladder fosters better stability and prevents potential hazards that could arise from inadequate space.
