What is the acceptable horizontal alignment variance for end ladder treads?

The acceptable horizontal alignment variance for end ladder treads is 2 inches. This standard is important for ensuring safety and functionality in rail mechanics. A variance greater than this can lead to potential hazards, such as slipping or difficulty in safely accessing the ladder. Maintaining this specific alignment helps in providing a consistent and stable surface for workers, reducing the risk of accidents and ensuring compliance with safety regulations. Therefore, adhering to the 2 inches guideline is critical for promoting a safe working environment on rail equipment.
