Travelways steeper than which angle must have ladders or stairways?

The requirement for ladders or stairways on travelways that exceed a specific steepness is based on safety regulations to ensure safe access and egress in mining operations.

For travelways steeper than 35 degrees, the installation of ladders or stairways becomes necessary. This is because as the slope increases, the risk of slips, falls, and other accidents rises substantially. A slope of 35 degrees is generally considered the threshold where the grade becomes challenging to navigate safely without additional support.

In practical terms, ladders and stairways provide a stable and secure means of traversing steep angles, ensuring that personnel can move between levels without compromising their safety. This requirement is part of adhering to mine safety standards, which aim to minimize accidents and enhance the overall safety of mine operations. Therefore, understanding the 35-degree requirement is crucial for maintaining compliance with safety regulations and protecting the health and well-being of mine workers.
