With pools set to open across the country, a new report offers a warning about the potential for injury from the chemicals used to keep pools clean.

The report from the Centers for Disease Control links 5,000 visits to the emergency room in 2012 to pool chemicals.

Researchers found 46% of the injuries occurred among kids and teens, and more than a third happened at home.

The CDC reported, nearly three-quarters of the injuries took place between Memorial Day and Labor Day weekend.

40% happened on the weekends.

Most often, people were overcome by strong vapors or fumes from the chemicals.

Experts remind folks to use goggles and masks when handling pool chemicals. The CDC also warns to never mix chlorine products with acids.
