Having a Lifeguard at your private pool party or event can mean the difference between life and death for someone you care about. Lifeguards cannont prevent all injuries, but when a slip, fall, or other accident does occur, they are trained to respond in a way that will prevent minor injuries from becoming serious. In the event that the injury does become serious, properly trained lifeguards greatly increase the chances of survival during those critical moments before EMS can arrive.
