What is the maximum user load per square foot for a class B public swimming pool with deck areas at least twice the water surface area in the deep area?

The correct answer is based on the established standards for public pools, which categorize them into classes based on their intended use and design specifications. A Class B public swimming pool typically accommodates a larger number of users compared to other classifications, particularly when the deck area is ample, as stated in the question.

For a Class B pool, the requirement stipulates that the maximum user load is calculated on a per square foot basis. In this case, the correct maximum load is 10 square feet per person when there is sufficient deck area—specifically, if the deck areas are at least double the water surface area in the deep end. This allows not only for the safe distribution of users but also for adequate space for movement and emergency access.

The rationale behind this standard is to ensure safety and comfort for users while mitigating overcrowding, which can lead to increased risk of accidents, drowning, or health hazards. Therefore, understanding the maximum user load contributes significantly to effective pool planning, compliance with safety regulations, and overall management of pool operations.
