What is the length range for ladder rungs on scaffolds?

The correct answer reflects the standard length range for ladder rungs on scaffolds, which is generally accepted to be between 11.5 inches and 16.75 inches. This measurement is crucial for ensuring the safety and stability of individuals working at heights on scaffolding. Rungs that are within this range provide an adequate foothold for workers, reducing the risk of slips and falls.

The specified range takes into account factors such as the average foot size and the need for a secure grip while climbing. Rungs that are too narrow can lead to safety hazards, as they may not adequately support the foot of an average worker, while rungs that are too wide may hinder the ability to ascend and descend safely.

Understanding this range is essential for scaffold builders and safety inspectors, as it aligns with industry standards set forth by safety regulations, ensuring that scaffolds are constructed in a manner that prioritizes worker safety.
