10/20

A lifeguarding term describing the 10/20 Protection Standard set by Ellis & Associates. Lifeguards must:
- Within 10 seconds: Scan their zone and detect any signs of trouble.
- Within 20 seconds: Be able to reach and intervene with a guest in distress.

Following the 10/20 Protection Standard to recognize and respond to any aquatic emergency within a total of 30 seconds has proven to save lives.

This 10/20 Protection standard is also the basis to create and validate lifeguards' zones of protection, which are specific areas of water assigned to each lifeguard. If a lifeguard cannot maintain 10/20 within their zone, it must be adjusted.

The foundation behind the Ellis Scanning Method.
The head lifeguard said our zones aren’t 10/20-compliant, so they’re adjusting and revalidating them before opening.

He’s got that 10/20 locked down.
