At what elevation must a stairway or ladder be provided for access?

A stairway or ladder must be provided for access at an elevation of 19 inches because this measurement aligns with the safety standards established to prevent falls and ensure safe access to elevated work areas. Elevations greater than 19 inches create a significant risk of injury, making it essential for safety protocols to include proper means of access such as ladders or stairways.

Providing a means of access at this height is crucial to mitigate hazards associated with working at elevation. This requirement also reflects best practices in maintaining safe work environments, emphasizing the importance of compliance with safety regulations to protect workers.
