(HealthDay News) -- Children's swing sets must be properly selected and assembled to prevent serious injury.

Here are recommendations on choosing and assembling a swing set, from the U.S. National Safety Council:

  • Make sure the equipment is very sturdy, and look for sets that can be changed or upgraded to accommodate your child's growth.
  • Secure the legs of the set in below-ground concrete. If you use anchors that come with the set, keep them below ground. Make sure all cables are taut. Cap any screws or bolts.
  • Slides should not be too steep -- no more than a 30-degree slope. The slide must have tall sides to prevent falls, and an area at the bottom where children can regain balance and sit upright.
  • Avoid sets with "S" hooks, or any parts that can pinch, cut or crush small fingers. Avoid any rings that are less than 5 inches or greater than 10 inches in diameter.
  • In general, equipment should not be higher than 8t feet tall. And metal equipment, used in hot weather, can lead to burns.
