Do you have to empty a pool if someone vomits by law in public pool?

It is not a nationwide requirement by law to drain an entire pool if one individual becomes sick in the pool. Individual public health codes vary by state, county, and city, and some public health guidelines recommend certain actions following an incident when someone vomits in a public swimming pool.

Here's a general overview of common public health guidelines for public pools:

1. Immediate Response: The pool staff is typically trained to respond promptly when an incident of vomit occurs. They should immediately close the affected area of the pool and prevent anyone from swimming in that section.

2. Disinfect the Area: The area where the incident occurred is thoroughly disinfected using recommended chemicals and following the specific pool safety guidelines.

3. Test Water Quality: Water samples are taken from the affected area and analyzed to ensure that disinfectant levels are sufficient to neutralize any contamination.

4. Determine Closure: The decision to close the entire pool or just the affected area for a specific period depends on the local public health regulations. In many cases, only the section where the incident happened may be closed for a certain amount of time (usually around an hour) for enhanced cleaning and disinfection.

5. Reopen: Once water test results confirm the safety of the pool, the affected area (or the entire pool if necessary) is reopened for public use.

It's important to note that these guidelines might vary based on the specific health codes in your location, so it's always best to refer to the local public health authority or the regulations of the specific pool facility for accurate information.
