Kites should be flown in open, unobstructed spaces, such as schoolyards, parks, farm fields, empty parking lots and beaches.
Do not fly kites on public streets and highways, areas with airplane traffic, on bumpy or rocky land or near trees.
Never fly kites in stormy or wet weather.
Never fly a kite near electric lines or antenna or use any metal in the line.
Wearing gloves can prevent line burn, caused by the kite cord pulling too quickly across the fingers.
Use string that is considerably stronger than the kite's estimated pull, but not one made of wire or tinsel cord.
Before flying a kite, make sure it has been properly assembled.
Don't fly your kite in winds stronger than recommended. In general, flat and delta kites do well in light to medium winds (6-15 mph), while box kites and parafoils kites fly better in stronger winds (8-25 mph). Winds over 25 mph are generally too strong for kites.
If you tangle lines with another kite, don't yank the lines or they might break. Fliers should walk together and the tangle will slide down the line to where it can be unwrapped.
Never climb a tree or pole to retrieve a kite from an overhead wire or roof. It is better to lose a kite than risk your life. Notify your local power company if a kite becomes tangled in its lines.
Watch where you are going, particularly if you are running to launch a kite. Don't let your head stay in the clouds with the kite. Be aware of your surroundings at all times.
Never let your kite go out of sight behind a hill, building, trees or fence. Auto accidents have occurred when kites have dropped on a windshield when the vehicle was obscured from the flier.
Parents should supervise flying activities of children and help them learn to fly kites skillfully and safely. Balance, understanding of winds, proper adjustment of the various parts under varying conditions will all come with practice and will increase the enjoyment of the sport.
