What is the minimum width and thread spacing of side ladders?

The minimum width and thread spacing of side ladders is set at 16 inches. This specification ensures that ladders can be used safely and comfortably by crew members who need access to railway equipment and structures. An adequate width allows for better stability and reduces the risk of accidents, as it provides sufficient space for workers to place their feet securely on the rungs as they ascend or descend.

In the context of rail operations, where personnel often work with heavy tools and equipment, the specifications help to maintain workplace safety standards. The 16-inch width aligns with ergonomics principles, minimizing the risk of slips or falls when workers are accessing different levels of tracks or rail cars. Therefore, understanding the importance of these specifications not only ensures compliance with safety regulations but also promotes a safer working environment for all employees involved in rail maintenance and operations.
