recently, the net red balloon is really hot and exploding. It's especially beautiful at night, so it's sought after by many children and young people. But what you don't know is that the net red balloon has a great potential safety hazard, which may harm your health if you are not careful! So why does the net red balloon explode?
What happened to the explosion of the net red balloon? It happened at 9:00 p.m. on November 27. Two men and two women, four young people, came out after eating in a restaurant. When they saw the glowing net red balloon, they bought six and took a taxi to leave. But on the way, one of the men smoked, accidentally splashed Mars on the balloon, banged, and then no one else reacted. The other five balloons, all exploded. Four people all had different degrees of burns, two of them were seriously injured.
What is the cause of the explosion? The danger of hydrogen
Hydrogen is a colorless, odorless, non-toxic, flammable and explosive gas, which is dangerous to explode when mixed with fluorine, chlorine, oxygen, carbon monoxide and air. The mixture of hydrogen and fluorine can explode spontaneously in low temperature and dark environment. When the volume ratio of hydrogen to chlorine is 1:1, it can also explode in light. Because hydrogen is colorless and tasteless, the flame is transparent when burning, so its existence is not easy to be found by the senses. In many cases, the odorous ethyl mercaptan is added to hydrogen to make the sense of smell, and the flame can be given color at the same time.
Although hydrogen is nontoxic, it is inert to human body in physiology, but if the content of hydrogen in the air increases, it will cause anoxic asphyxia. As with all cryogenic liquids, direct contact with liquid hydrogen will cause frostbite. When liquid hydrogen overflows and evaporates suddenly in large area, it will cause anoxic environment, and may form explosive mixture with air, which will cause combustion and explosion accidents. Mixing with air can form explosive mixture, which will explode in case of heat or open fire. The gas is lighter than air. When it is used and stored indoors, the air leakage will rise and stay on the roof, which is not easy to discharge. In case of Mars, it will cause explosion. Hydrogen reacts violently with halogens such as fluorine, chlorine and bromine.
The net red balloon has led lights on its surface, which are tied to a transparent plastic tube. The bottom of the plastic tube is equipped with a battery, and the balloon is filled with helium or hydrogen gas. Helium is relatively safe, but if it is filled with hydrogen, it will explode as soon as it touches Mars.
"Bobo ball" although good-looking, but the purchase and use of attention to safety. When buying any inflatable balloon, it is necessary to ask whether it is hydrogen balloon or helium balloon. If you buy a hydrogen balloon, be sure to stay away from the fire source and not play in an airless space. In addition, because the LED light device on the 'Bobo ball' is relatively simple, if the circuit is short circuited and heated, it is likely to pose a threat to the safety of the child, so children need to be watched by adults when playing.
