Are balloons safe?

It is recommended to use high-quality balloons that meet environmental requirements and can be decomposed by microorganisms to make styling balloons. Firstly, they are safe and not easy to break. Secondly, they can be used for complex weaving with higher difficulty. In addition, when designing with balloons, since air is used, there are no safety concerns. However, if you use a round balloon to float, be sure to use safe helium for filling, and hydrogen is prohibited. Also, never let children put balloons in their mouths, as this may cause a choking hazard. In addition, although domestic legislation has not yet banned the large-scale release of helium-filled balloons during festivals, please abide by the following principles:
1) Do not release aluminum foil balloons in the air (aluminum foil is not easy to decompose, there is a risk of short circuit when aluminum foil touches high-voltage wires, and aluminum foil can cause trouble in flight)
2) Do not use metal wire to tie helium-filled rubber balloons for the same reason as above.
3) Helium-filled rubber balloons should be tied to a weight. Do not tie a large number of balloons to the same weight. Because the balloons will not spread out once they fly away, they can easily get hung up on wires, or if they fall, the wires can become entangled in animals and cause harm.
Therefore, as long as the above precautions are followed, balloons are perfectly safe.
