What action should a lifeguard take to promote safety for a day camp at an aquatic facility?

Administering swim tests for all participants is essential to ensure safety at an aquatic facility, especially during a day camp. This action helps assess each child's swimming ability and ensures that they are placed in appropriate areas of the pool or aquatic environment. By understanding the skill level of each camper, a lifeguard can better monitor safety, prevent accidents, and provide necessary supervision. This not only enhances the safety of the participants but also allows for more tailored instruction and activity planning, catering to the varying skill levels present. Knowing who is a strong swimmer and who needs additional support enables lifeguards to effectively manage the environment and reduce the risk of drowning or accidents.
