And among the children ages 1 to 4 who die of unintentional injuries, drowning accounts for one-third of the deaths. The American Red Cross recommends protecting home pools with a gate. “Secure your pool with appropriate barriers. Completely surround your pool with a 4-feet high fence or barrier with a self-closing, self-latching gate. Place a safety cover on the pool or hot tub when not in use and remove any ladders or steps used for access. Consider installing a pool alarm that goes off if anyone enters the pool,” says the American Red Cross website. The American Red Cross also advises that parents take first aid and CPR courses to help in an emergency. They provide step-by-step instructions on their website, and offer classes around the country, found here.
