What safety feature must all public swimming pools have available?

In the context of public swimming pools, having a first aid kit readily available is essential for immediate response to any injuries or medical emergencies that may occur. A first aid kit typically contains a variety of medical supplies such as bandages, antiseptics, and emergency care items, allowing trained personnel to address minor injuries promptly and potentially stabilize more serious situations until professional medical help can be sought.

While other safety features, such as life rings and emergency showers, are important for specific safety scenarios, the first aid kit is a critical resource that addresses a wide range of first aid needs. It ensures that public pool operators are prepared to handle minor injuries or emergencies effectively, thus enhancing the overall safety of patrons at the facility.
