Kids love to play -- and play hard. So, you should remove danger in your yard. Today you'll learn how to "oops proof" their play, so they'll stay safe, every day. Here's how: Falls account for 80 percent of all injuries. Play sets should have shock-absorbing rubber mats or at least 9 inches of sand or wood chips below. Grass alone doesn't provide enough protection. Strangulation is the No. 1 cause of fatalities. Be sure spaces between all rails or ladder steps are less than 3 inches or more than 9 inches to avoid trapping, and never attach ropes or straps to play equipment. Remove all rocks and potential tripping hazards. Install safety covers on all electrical outlets and inspect regularly for loose bolts, stability, and things like hidden sharp edges. Check for any new bee and hornet nests too. Forty-six thousand children are hurt every year on home playgrounds. Play it safe! And that's the On The House tip for today.
