Lifeguards can work at a variety of locations, including recreational swimming pools, water parks, beaches and lakes. They work with other Lifeguards to ensure the safety of swimmers, perform rescues, and in certain situations, perform lifesaving first aid. Their job is to ensure that guests have a fun and safe environment in which to swim and lounge about with family and friends. They may also be responsible for cleaning the area and checking water quality. This is especially important for Pool Lifeguards.
