Inattentive text-messaging lifeguards are becoming a safety concern in swimming pools and waterfronts.

As the New York Times reported, at a public pool in Arizona this summer, a child panicking in the water was rescued by an adult visitor -- and not the lifeguard on duty. Witnesses at the pool said the lifeguard was texting during the incident.

According to the American Lifeguard Association, it was not an isolated incident. Bernard Fisher, the association's director, said this is the first year that text-messaging by lifeguards has been an issue, and there were several dozen complaints over the summer.

Many pools and waterfronts have mandated a no-electronic-device policy for their lifeguards to address this concern.

According to the New York Times article, even sporadic and quick text messaging is a violation of standard lifeguarding practice, as lifeguards are trained to scan areas in 10-second cycles, and a person can drown in as little as 20 seconds.
