In recent years, accidents caused by hydrogen balloons** have been common.
At the end of the countdown, the New Year's Eve bell rang, and tens of thousands of people collectively released a large number of balloons, but as a result, the balloon touched the high-voltage power line and triggered **, which instantly thundered and thundered, and the red light around the sky was reflected.
This is a thrilling scene when the accident occurred on the pedestrian street of Jianghan Road in Wuhan City in the early morning of January 1.
Picture: Weibo screenshot The multi-segment balloons uploaded on the social platform*** show that the sky was full of balloons one second ago, and the woman exclaimed: "It's so beautiful!."In the next second, there were two balloons**, and the crowd exclaimed. Thankfully, the accident did not cause a person.
From a national perspective, on Chinese New Year's Eve, not only Wuhan, but also Nanjing, Hangzhou, Guangzhou and other cities have balloon release activities, and they are all spontaneous actions of the masses, but the luck of the latter cities is better.
In any case, the thrilling scene on Chinese New Year's Eve on Jianghan Road in Wuhan once again issued a warning to people:The hydrogen balloon, which seems to be harmless to humans and animals, is actually "hydrogen" that public safety cannot bear。Once a balloon causes serious injury or even death, it is a heavy burden that every family cannot bear.

The hydrogen balloon becomes a "bomb" in seconds, and it is impossible to prevent itThe hydrogen balloon is not only a perfect decoration for the festive atmosphere, but also a "baby coaxing artifact" and "photo artifact", and it is a flowing and sought-after commodity in the eyes of traders. Young people and parents attracted by its light and cute appearance willingly dig out their walletsApparently not recognizing its danger。"If you don't let the balloon touch the high-voltage power lines, you'll be fine"There are many people who have such naïve thoughts.
At present, it is believed that there are three main potential safety hazards in the release of balloons: First, the balloon is out of control and endangers aviation safety, in case the aircraft engine inhales the balloon or the balloon collides with the aircraft, the consequences are unimaginable;The second is the balloon **, which catches fire, endangering the safety of people's lives and property;Third, the balloon rises and touches high-voltage power lines, endangering national power security and potentially causing widespread power outages.
Balloons** can cause major fires. Pictured: Can the 123rf become safe if you don't release the balloon and hold it in your hand?
Actually, no!According to statistics,Accidents caused by hand-held hydrogen balloons occur from time to time in China every year, and many of them cause serious injuries and even deaths
In life, hydrogen balloons are very prone to accidents. Figure: Network screenshotHydrogen balloons are especially afraid of fire!Firefighters have done experiments: when the lighter is close to the hydrogen balloon, in just 1 second, the hydrogen balloon will be *** and the source of fire in life, there are too many opportunities and unexpected ways to meet the balloon.
On December 20, 2022, in a hot pot restaurant in Putian City, Fujian Province,There was a little girl who put a hydrogen balloon on the stove, the balloon instantly ignited a huge fireball, fortunately the child was fine.
On February 18, 2021, when vendors were selling balloons at the gate of a park in Zhenjiang City, Jiangsu Province, an elderly man was smoking a cigarette and passing byA gust of wind blew the balloon onto the old man's cigarette butt, triggered **, resulting in 2 injuries.
An unextinguished cigarette butt can instantly trigger a hydrogen balloon**. Picture: 123RF On November 1, 2020, a man in a KTV elevator on Jiefang West Road in Changsha, Hunan Province took out a lighter to burn the knotted rope because the balloon rope was deadHowever, at the moment of ignition and burning the rope, the hydrogen balloon**A raging fire broke out in the elevator, and the accident caused 5 people in the elevator to suffer burns of varying degrees.
What's even more terrifying is that hydrogen balloons can explode without encountering open flamesThis is a cognitive blind spot for many people, and they didn't expect that an ordinary hair dryer could turn a balloon into a "bomb". In June 2023, a child in Jieyang, Guangdong Province was playing in the living room with a hydrogen balloonaccidentally touched the freshly used hair dryer in my mother's hand, and then it exploded instantly, mom was burned.
In a real case, a hydrogen balloon exploded when it encountered a freshly used hair dryer. Picture: Guangdong Fire Official*** On May 9 of the same year, a girl in Hefei, Anhui Province bought a hydrogen balloon and returned to the dormitory. This time, it was caused by static electricity caused by the friction between the girl's hair and the rubber on the surface of the hydrogen balloon**
The above-mentioned accidental accident undoubtedly magnifies the danger of hydrogen balloons, and also proves the sentence "tomorrow or accident, you never know which will come first".
Behind the hidden danger is a dangerous gas that is difficult to identify with the naked eyeThere are so many hidden dangers in the beautiful hydrogen balloon, and it is related to the gas it is filled with. If you want the balloon to fly and float in the air, the density of the gas is required to be less than that of air, so the gas filled in the balloon is either hydrogen or helium.
Hydrogen is a reactive gas, flammable and explosive, and is one of the most common flammable and explosive gasesThe lowest ignition energyThe limit of its presence in the air is between 4% and 75%. Huang Weizhi, captain of the Guangzhou Public Crisis Prevention Association, pointed out, "Because hydrogen is a flammable gas,If it is exposed to heat or encounters an open flame, it can easily cause deflagrationEven if the sun is too strong and shines for a long time, the balloon will not be able to withstand the expansion force, and the outer wall will burst. ”
Behind the beautiful hydrogen balloon lies great danger. Figure: 123RF What's even more worrying is that in the actual life scene, the hydrogen from the hydrogen balloon is very easy to leak, and there is no need for an open flameHydrogen balloons can ignite or detonate from static electricity caused by rubber friction, cigarette butts that have not been extinguished, and even car exhaust。In particular, the heavy clothes worn in winter are chemical fiber materials, which increases the possibility of "static electricity biting", and once it encounters a hydrogen balloon, it is even more dangerous.
Also, if the balloon is filled with hydrogen that is not pure enough and a small amount of air is mixed into the filling process, the risk of hydrogen balloons** is even higher.
In 2006, the relevant state departments jointly issued the "Notice on Further Strengthening the Safety Management of Balloon Release".It is clearly stipulated that the filling of hydrogen balloons and their lift-off objects in public places is prohibitedIt is strictly forbidden to fill hand-held hydrogen balloons on various occasions, and it is recommended to replace flammable and explosive gases such as hydrogen with inert gases as fillers for balloons, so as to reduce potential safety hazards.
Hydrogen balloons are not allowed in public places. Figure: Nanjing Metro's official Weibo Although helium is an inert gas and helium balloons are relatively safe, the market for helium is several times higher than that of hydrogen, so it is not excluded that some traders take risks to process and sell hydrogen balloons in order to make huge profits.
39 Deep Breath visited and learned that the balloons sold on the market are inflated finished products, only based on appearance analysisIt is impossible to tell what kind of gas the balloon is filled withEven professional subway security personnel can't tell whether there are flammable, explosive or toxic gases in the balloon, so we can only ask the vendor when buying the balloon.
Before you are sure whether the purchased balloon is filled with helium, keep one thing in mind:Do not tie the balloon to our wrists or the buttons of our clothes, otherwise we are very vulnerable to severe burns or burns if it happens**
When children play with hydrogen balloons, they should pay special attention to safety. Figure: 123RF
Firefighters reminded that when playing with balloons, you should choose to play in an open areaDo not expose to the sun, and stay away from fire, sharp objects, etc., parents should especially educate their children to pay attention to safety. Secondly,Do not bring balloons into elevators, buses, or put them in your own carOnce it happens, the impact of the enclosed space will be much greater, and the damage to people will be greater.
