What is the required minimum width for industrial fixed stairs?

Explanation:
Industrial fixed stairs must provide a minimum clear width of 22 inches. This is the unobstructed distance between the finished surfaces of the stair sides, measured along the entire run and excluding handrails. Keeping at least 22 inches ensures safe, unobstructed passage for a person with typical footwear and avoids crowding or snagging on rails or walls. An 18- or 20-inch width would be too narrow to meet the requirement, while 24 inches meets and exceeds the minimum.
