What is the minimum horizontal tread depth required for stairs?

The minimum horizontal tread depth required for stairs in commercial pools is 10 inches. This measurement is crucial because it affects both the safety and accessibility of the stairs for patrons. A tread depth of 10 inches provides enough space for individuals to place their feet securely, reducing the risk of slipping or tripping as they enter or exit the pool.

The regulation of a minimum tread depth also takes into account various factors, including the size of the average foot and the need for stable footing when maneuvering on the stairs, especially in a wet environment like a swimming pool. Ensuring that each tread meets this minimum depth helps maintain a consistent standard that enhances user safety.

Overall, adhering to the requirement of a 10-inch minimum tread depth is essential in promoting safety standards in commercial pool operations, helping protect the well-being of all users.
