Drowning Is the Top Killer of Kids 1–4, Pool Fences 4 Ft+
CDC says more children ages 1 to 4 die from drowning than from any other cause of death. Drowning happens in seconds and is often silent; when children are in or near water, including bathtubs, designate one adult to watch them closely and constantly.
If you have a pool at home, CDC recommends a four-sided fence at least 4 feet high that separates the pool from the house, with self-closing and self-latching gates. This article follows CDC’s drowning prevention page on supervising children, pools, swim lessons and life jackets, and what adults should watch for themselves. Health situations differ, so ask your health care provider if you have questions.
Supervising children
CDC explains (CDC Preventing Drowning):
- Designate one adult: when children are in or near water, including bathtubs, designate a responsible adult to watch closely and constantly; you can also assign a specific adult to each child.
- No distractions: the adult watching shouldn’t read, use the phone, or drink alcohol or use drugs.
- Watch even with lifeguards: supervise closely even when lifeguards are present.
- At someone else’s home or a new place: learn what water risks are there first.
Pools
- Four-sided fence: use a four-sided fence at least 4 feet high that fully encloses the pool and separates it from the house.
- Self-closing, self-latching gates: the fence gates should close and latch on their own.
- Put toys away, lock doors: remove toys from the pool area when it isn’t in use, since they can attract children; after swim time, shut and lock doors that lead to the water.
Swim lessons and life jackets
- Formal swim lessons: can reduce the risk of drowning; children who have had lessons still need close and constant supervision in or around water.
- Life jackets when boating: life jackets reduce the risk of drowning while boating for people of all ages and swimming abilities.
- Natural water: children should wear life jackets for all activities in and around natural water.
- Air-filled and foam toys: don’t rely on them; they are not safety devices.
What adults should watch for themselves
- Learn CPR: your CPR skills could save a life in the time it takes paramedics to arrive. CDC says many organizations, such as the American Red Cross and the American Heart Association, offer CPR courses online and in person.
- No alcohol: don’t drink before or during swimming, boating or other water activities, or while supervising children.
- Swim with a buddy: always swim with someone, and choose places with lifeguards when you can.
- Check the forecast: check the weather forecast before activities in, on or near water.
- Medications and health conditions: don’t swim if you take medications that affect your balance, coordination or judgment; people with seizure disorders need one-on-one supervision around water and can consider showers instead of baths.
- Don’t hold your breath: don’t hyperventilate before swimming underwater, and don’t hold your breath underwater for long periods.
