Stairways must be installed at an angle of at least 30 degrees but no more than 50 degrees from the horizontal, according to OSHA (Occupational Safety and Health Administration) standards.
Explanation:
- Minimum (30 degrees): Ensures the stairway is not too shallow, providing a safer ascent and descent.
- Maximum (50 degrees): Prevents the stairway from being too steep, which could increase the risk of falls.
Maintaining this range ensures safety and usability for both construction and general use stairways
