If you’re guarding a pool or waterfront, your eyes are your #1 tool. The phrase “Scan every 10 seconds, reach within 30” isn’t just a catchy line—it’s life-saving protocol.
Why 10 Seconds?
Drowning can be silent. It doesn’t look like thrashing or screaming—it can just be a head slipping beneath the surface with no splash. Within 10 seconds, a swimmer in trouble can already be submerged. Your job is to detect it before that happens.
The Science Behind It
Studies show that most drowning incidents happen with adults nearby—but they weren’t paying full attention. A full visual scan every 10 seconds ensures you catch irregular movement, floating objects, distressed body posture, or someone quietly sinking. This interval keeps your awareness sharp without causing fatigue.
Reach Within 30 Seconds
If you do spot someone in trouble, you must be able to physically reach them within 30 seconds. That means your zone of coverage should never exceed what’s realistically reachable within that timeframe, whether swimming, walking along deck, or jumping in.
How to Scan Effectively
- Stand or sit high enough to see the entire zone
- Move your head—don’t just use your eyes
- Use an “S” or zig-zag pattern across the water
- Pause on each swimmer for a microsecond
- Check under water and surface reflections
Common Pitfalls
Distractions, chatting with coworkers, or zoning out during long shifts can make you miss something important. Use triggers—like tapping your leg every 10 seconds—to stay consistent. Rotate stations every 20–30 minutes to keep attention fresh.
This Isn’t Optional
“Scan every 10” isn’t a suggestion—it’s a standard. You’re the only thing standing between a safe swim and a tragedy. Practice it. Live it. Your focus saves lives.
If you didn’t scan it, you didn’t see it.
