The National Day holiday is coming
There are more vendors selling balloons on the streets of the scenic area
When traveling with a baby
Never buy substandard hydrogen balloons
This type of balloon is very popular with children
But it's really a "little grenade"
Recently, Taiyuan, Shanxi
A mother playing with her child
The hydrogen balloon in his hand suddenly exploded
The child's eyelashes and eyebrows are burned
Half of the hair was also burned
Fortunately, the child's health is fine
There has been an accident in which a hydrogen balloon exploded and caught fire
Common
Why do hydrogen balloons explode?
Hydrogen is a flammable and explosive gas, when the hydrogen balloon rubs against other objects to produce static electricity, when it encounters open flames, sun exposure or excessive pressure, it may cause an instantaneous explosion and burn the surrounding people.
Tangerine, grapefruit, lemon
Can also detonate a balloon?
In fact, this "temperamental" hydrogen balloon can explode even if it does not encounter an open flame↓
The peels of fruits such as oranges, grapefruits, and lemons contain an aromatic hydrocarbon called limonene, which belongs to the class of organic solvents, and the main material of balloons is polymer organic compounds such as latex and rubber. According to the "similarity dissolution principle" in chemistry, when these two organic substances come into contact, they will missolve with each other, resulting in a local thinning of the surface of the balloon and an explosion.
Attention! After peeling citrus fruits such as oranges and oranges, be sure to wash your hands before touching the balloons!
Such a dangerous hydrogen balloon
Why are people still selling?
In July 2006, the relevant state departments jointly issued the "Notice on Further Strengthening the Safety Management of Balloon Release", requiring the use of inert gas instead of hydrogen and other flammable and explosive gases as the filling of balloons, and clearly stipulating that it is forbidden to fill and release hydrogen balloons and their lift-off objects in public places, and it is strictly forbidden to fill hand-held hydrogen balloons on various occasions.
In addition to hydrogen, the inert gas helium can also float balloons. However, the market price of helium is about 10 times that of hydrogen, and some traders are still risking the processing and sale of hydrogen balloons, knowing that hydrogen is very dangerous. It is worth noting that helium balloons and hydrogen balloons are very indistinguishable from each other in appearance. If you are not sure what gas is filled, do not buy it.
Buy balloon toys
Do the following:
Avoid buying for children of a younger age
Balloons-type toys are not recommended for children under 3 years old; Children under the age of 8 should play with balloons under the supervision of an adult.
Choose a formal channel
Try to choose balloons produced by regular manufacturers, and do not buy them on the streets, stalls and other places. The balloons sold in these places are often "three-no" products, which are very easy to explode and injure people.
Pay attention to the balloon size
Avoid oversized balloons, which will have a greater impact when they explode.
Please take care when carrying
Do not tie the balloon to your child's wrist or the buttons of their clothes; Avoid bringing the balloon into an elevator, bus, or inside a vehicle, as the impact of the balloon in an enclosed space will increase significantly if it explodes.
Take care when inflating
Do not inflate the balloon too quickly, too much or too violently; Make sure to keep it away from your child's eyes during inflation.
Be careful when playing
Try to play with balloons in an open area and stay away from fire, sharp objects, etc.
