What specific rule should be enforced to prevent drowning risks for non-swimmers?

Enforcing the rule that non-swimmers stay in shallow water is crucial for their safety. Shallow water limits the risk of drowning, as it allows non-swimmers to remain in a zone where they can easily stand up if they begin to struggle or feel overwhelmed. In shallow waters, the less experienced swimmers can develop confidence while remaining safe and minimizing their risk of encountering deep water hazards.

While flotation devices can provide a level of safety and swimming in pairs can offer immediate help, the most fundamental way to prevent drowning in non-swimmers is to restrict their access to deep water. This proactive measure prioritizes their safety above all else, ensuring that they are in a controlled environment where supervision and assistance can be managed effectively.
