With parents and public officials recognizing the dangers of ultraviolet radiation and burn hazards on playgrounds, particularly during summer months, shade projects in recreation areas are finally receiving more attention and funding. Aside from issues of ultraviolet skin damage are concerns over playground equipment becoming dangerously hot during the summer. Most people who grew up in the 1970s remember scorching the backs of his or her legs at least once on a playground slide.
If your local park or playground decides to undertake a shade program, the first step is to document the shade that is already there and find ways to work with it. Sometimes pruning low-hanging branches can increase usable shady areas, as can moving equipment and seating into shaded areas. Scattered shade works well in areas where children are active and running around. In areas where children are sitting in one spot, or where they are playing in a confined area, more shade should be available. If your community is interested in adding natural shade instead of or along with artificial shade structures, you'll need to assess the soil and other factors like strong winds that will affect the selection of species of shade trees.
In most cases, a combination of natural shade and artificial shade structures works best. Types of shade structures include permanent pergolas and verandas, marquees and tents, awnings, shade sails, and portable shade structures. Shade scaffolding can be constructed of fiberglass, PVC, or steel. Shade cloth that is dark and closely woven will block or absorb UV radiation better than lighter, more loosely woven shade fabrics. Fabrics should state the level of UV protection they provide, and should provide the equivalent of a Sun Protection Factor (SPF) of 15 or greater.
Most artificial shade structures are made from sheets of colored polyethylene attached to corrosion-resistant galvanized steel frames. They come in different colors to coordinate with existing playground structures and are designed to protect people on playgrounds from UV radiation and other weather elements. These structures are designed to stand up to not only high winds, but also local building codes.
Children usually receive 80% of their lifetime sun exposure before the age of 18. Sun damage during childhood increases the risk of developing skin cancer in adulthood. Protection from UV radiation on playgrounds and parks can make significant headway in preventing future cases of skin cancer. In recent years, suppliers of shade structures have come to the forefront of recreational design as people realize the health benefits and increased comfort that come from adding shade to public spaces. And adding shade to existing playgrounds does not mean great expense and upheaval.
The American Academy of Dermatology (AAD) feels so strongly about protecting children from UV radiation that it awards annual grants of $8,000 each for the purchase of shade structures for outdoor recreational areas. Applications for 2009 grants are due by April 10, 2009 at 5 p.m. Central Time. Recipients of the grants should be notified in June.
AAA State of Play offers playground shade made with steel and fabric roofs. By providing shade equipment such as balance beams made with metal will remain cool.
