A lifeguard is a trained professional responsible for ensuring the safety of individuals at swimming pools, beaches, and other aquatic environments. They monitor swimmers, enforce safety rules, and are prepared to respond to emergencies, such as drowning or injuries. Lifeguards are typically certified in first aid, CPR, and water rescue techniques. In addition to their rescue duties, lifeguards often provide education on water safety and swimming skills. They may work in various settings, including public pools, private clubs, and beaches. Lifeguards play a crucial role in preventing accidents and promoting a safe environment for all water activities.
