Chapter 3 Patron Surveillance A lifeguard’s primary responsibility is to en- sure patron safety and protect lives. A pri- mary tool to accomplish this function is pa- tron surveillance—keeping a close watch over the people in the facility. Lifeguards will spend most of their time on patron sur- veillance. To do this effectively, they must be alert and attentive at all times, supervis- ing patrons continuously. 28 Lifeguarding EFFECTIVE SURVEILLANCE Distressed Swimmer For a variety of reasons, such as exhaustion, cramp or With effective surveillance, lifeguards can recognize be- sudden illness, a swimmer can become distressed.
