What document outlines the closure conditions for a public pool based on pH levels?

The document that outlines the closure conditions for a public pool based on pH levels is Chapter 64E-9. This chapter is part of Florida's administrative code specifically dealing with public swimming pools and bathing places. It establishes health and safety regulations that include the permissible limits for chemical levels, such as pH, to ensure the safety of pool users.

In the context of public pools, maintaining the correct pH balance is crucial not only for the comfort of swimmers (to prevent irritation to skin and eyes) but also for the effectiveness of disinfectants used in the water. Chapter 64E-9 provides the standards and protocols, including procedures for closing a pool if the pH levels fall outside of the acceptable range, to ensure public safety.

The other options do not specifically address the management and closure conditions for swimming pools based on pH. The Florida Building Code focuses on construction aspects, the National Electric Code pertains to electrical safety, and ANSI Standards cover various safety protocols but do not specifically lay out closure conditions for public pools. Thus, Chapter 64E-9 is the most relevant document concerning the regulation and management of public pool health standards, including pH levels.
