With pools set to open across the country, a new report warns about the chemicals used to keep pools clean.
The report from the CDC links 5,000 visits to the emergency room in 2012 to pool chemicals.
Nearly half of the patients were children and teens and more than a third happened at a home.
Most often, people were overcome by strong vapors or fumes from the chemicals.
Experts remind people to always use goggles and masks when handling pool chemicals.
