 Additional responders work to reach the victim and then pull on the line to bring that person to shore. Dangers at the beach aren't just in the water. Lifeguards must also keep an eye on what's going on in the sand, even if it's behind them. That's why one thing we emphasize with our rookies is a scan, always being on point, watching the water, of course, but you also got to watch what's going on in the back of the beach.
