The minimum spacing between rungs, cleats, or steps of a fixed ladder on a construction site shall be?

The minimum spacing of 10 inches between rungs, cleats, or steps of a fixed ladder is established to promote safety and usability for individuals using the ladder. This distance is designed to accommodate the average foot size and ensure that users can comfortably and securely place their feet on each rung as they ascend or descend the ladder. Adequate spacing contributes to overall stability and minimizes the risk of slipping or missing a step, which can lead to serious accidents or injuries on a construction site.

Compliance with this specification is critical in maintaining a safe working environment, as well as adhering to industry standards and regulations. The spacing is determined based on ergonomic considerations, thus ensuring both safety and efficiency while using the ladder.
