What is the recommended lifeguard-to-swimmers ratio?

• A. 1 Lifeguard Per 25 Swimmers
• B. 1 Lifeguard Per 15 Swimmers
• C. 1 Lifeguard Per 50 Swimmers
• D. 2 Lifeguards Per 25 Swimmers

Answer: (A)

The main idea here is that lifeguards must have enough attention to scan the whole area and reach a swimmer in trouble quickly. One lifeguard for every twenty-five swimmers is the standard recommendation because it keeps surveillance practical while still allowing fast response to someone who needs help. If there were more swimmers per lifeguard, monitoring gaps could appear and response times could increase. A smaller ratio would boost safety but needs more staff, while a larger ratio reduces safety; having two lifeguards for twenty-five swimmers would be even more protective but isn’t the baseline for general supervision.
