M: "Go to the playground and have fun. " Parents will often say to their kids. But they should remember playgrounds can be dangerous.
W: Yeah, each year about 200,000 children end up in hospital emergency rooms with playground injuries. Many injuries involve falls from too-high equipment onto too-hard surfaces. Nearly 70% of the injuries happen on public playgrounds. Recent studies show they maybe badly designed that protective services are inadequate and their equipment is poorly maintained. Bob, what's your view?
M: Parents should make sure that the equipment in playground is safe and that children are playing safely. Last year the national programme for playground safety gave the nation's playground a grade of "C" for safety after visiting more than 3,000 playgrounds nationwide. Parents should watch closely. They should always be within shouting and running distance of their children. Young children don't understand cause-and-effect, so they may run in front of moving swings. They're also better at climbing up than getting down, so they may panic at the top of a ladder. It's important for children to know you're watching them. Once they feel that sense of security, that's when they can be creative.
W: We hope our children can enjoy a safe world.
