What is one key responsibility of a lifeguard?

Monitoring the safety of swimmers is a primary responsibility of a lifeguard. It involves actively watching over individuals in or around the water to ensure they are safe, preventing accidents or drownings through vigilance and prompt action when necessary. Lifeguards are trained to recognize potential hazards, respond to emergencies, and provide immediate assistance when a swimmer is in distress. This role is critical as it directly relates to the well-being of all individuals in the aquatic environment, which is the central focus of a lifeguard's duties. Ensuring safety not only includes observing swimming activities but also encompasses assessing conditions such as water currents, weather, and the number of swimmers present.
