In the summer of 2014, Genesis Holmes, a 13-year-old teen, drowned in a rural pond. Shortly after, the Genesis Project was established in an effort to reduce the number of drownings that occur in the rural areas of Charles County, S.C., by providing swimming lessons, water safety classes, along with recreational programs and leisure activities.

Over the summer, a video emerged of a lifeguard spotting a child drowning in a crowded wave pool in Whirlin’ Waters Adventure Park in North Charleston, S.C., within seconds. The footage, which has been watched more than 15 million times by viewers, was posted by Lifeguard Rescue to bring awareness to the Genesis Project.

According to the Centers for Disease Control and Prevention, every day, 10 people drown to death. Two of those deaths are children younger than 14 years of age. The lifeguard shown in the video was trained to spot the signs, but do you know what drowning looks like?

Silent Signs of Drowning:

1. Person is unable to call for help and may be quiet because his or her mouth sinks below and reappears just above the water’s surface. It doesn’t give them enough time to exhale and inhale, let alone to call out for help.

2. Person’s head is low in the water and their face is difficult to see with his or her mouth at water level. An adult’s head may be tilted back with their mouth open, while a child’s head may fall forward.

3. Person remains upright in the water with no evidence of kicking. There is only a 20- to 60-second window before the drowning person is unable to stay above the surface and eventually submerges under water.

4. Person may not seem to be in distress. Sometimes a person may just seem to be looking up at the sky, shore, pool deck, or dock, which is why it’s important to ask if they’re OK. If the person responds with a blank stare, they may only have 30 seconds left to be saved. Fortunately, the child featured in the video was rescued within a few seconds.
