Is it true that the balloon exploded and burned many people in Celebrity on the Internet?

At present, a kind of "Internet celebrity balloon" named Bobo Ball is selling well in the street, which is highly sought after by children and couples. And just recently, this "Internet celebrity balloon" exploded:

A man accidentally spilled Mars on a balloon while smoking, and all six balloons exploded.

Everyone has different degrees of burns, the most serious of which is the second degree burn.

The balloon exploded and four people were burned.

The structure of luminous balloon is very simple. Its components include a transparent balloon, a string of colored LED light bars and two batteries. Although "beautiful in appearance", there are certain security risks.

A few days ago, four people were injured by internet celebrity balloons, and two of them were badly burned. Mr. Zhao (pseudonym), 26, still has a lingering fear when he recalls that scene.

He said that after a group of four people ate dinner that night, they saw someone selling such balloons on the road. They felt quite good and bought five or six balloons. Then four people got into a taxi with balloons. At that time, a brother lit a cigarette and touched the balloon, which suddenly exploded.

Mr. Zhao: At that time, the power was too great! I'm confused.

According to the doctor, these people all had different degrees of burns when they arrived, two were slightly injured and two were seriously injured. Mr. Zhao was the most seriously injured. According to the preliminary diagnosis, his face and limbs have reached second-degree burns, and the specific injury needs further diagnosis. And a woman with burns on her face.

Network hot-selling inflation unknown

The reporter found in some online shopping platforms that this luminous balloon, also called "bubble ball", is also very popular in online sales, and many shops have sold tens of thousands of pieces. The price is very cheap. The ordinary model includes a wave ball, an LED strip and three batteries. The price is 5-8 yuan.

As for what gas is in the balloon, vendors have different opinions. Some say it is hydrogen, while others say it is helium. There are also many shops that directly indicate that it is safe to use air.

According to the investigation, a box of helium gas 13 liter needs 72 yuan, which can fill 15- 17 balloons, and each balloon is about 5 yuan on average. If filled with hydrogen, the average cost of each balloon is only a few hairs.

According to the doctor, there have been mass accidents of hydrogen balloons burning and exploding before, but now for the sake of safety, balloons are generally filled with helium. Helium is an inert gas and relatively safe, but it does not rule out that some manufacturers use hydrogen instead of helium in order to save costs.

Hydrogen is a flammable and explosive gas, and it is difficult to judge hydrogen balloons and helium balloons from the appearance. Judging from the description of the explosive power of this balloon by the injured, it is likely that the balloon they bought used hydrogen as helium.

Consumer warnings have been issued by the European Union.

As early as March this year, the European Commission's Non-food Rapid Warning System (RAPEX) issued a consumption warning to balloon toys with unknown brand LED lights made in China.

The EU gave this warning for the following reasons:

"This product has the risk of chemistry, suffocation and injury, because the balloon is easy to burst, releasing small parts including button cell, LED lights and sharp nails, and may be swallowed by children, causing injury or suffocation to organs including esophagus and stomach; This product does not meet the requirements of toy safety directive and relevant European standards EN 62 1 15. "

Measuring the Power of "Internet Celebrity Balloon"

So, how dangerous is this online celebrity balloon? The reporter went to the Peking University Squadron of Fengtai District Public Security Fire Brigade for an experiment.

Experiment 1 gives off a pungent smell when it is burned by an open flame.

First, firemen simulate what might happen when a bobble ball meets an open flame.

The reporter saw that the balloon was ignited at the moment when it touched the open flame of the lighter, and the charred water droplets continued to burn and catch fire on the table, turning into black glue with obvious pungent smell.

"The burning of this substance will produce toxic gases, which will cause burns and other injuries to people's respiratory tract. Once the water drops directly contact the skin, they will cause burns to the skin. " Chen Fang, the squadron leader of Yuquanying Fire Squadron in Fengtai District, said.

Experiment 2 Water droplets burn through the hat

The reporter put the prepared winter children's hat under the balloon to simulate the situation that the melt accidentally dripped on the clothes when the balloon was ignited by fire.

The reporter saw that the water droplets on the wool hat burned quickly and burned through the surface, and the fibers on the surface of the hat had been burned black. On the other hand, the inside of the hat was burnt through by vinyl.

Chen Fang said that this situation is very dangerous and will lead to serious burns on the skin on the head surface.

The fire department reminds:

When buying such balloons, be careful not to choose balloons containing flammable gases such as hydrogen and helium.

Secondly, carefully check whether there are cracks on the surface of the balloon and the connection point, and be sure to choose a regular manufacturer to buy it.

When playing with balloons, try to stay away from fire sources and sharp objects to prevent dangerous situations such as burning and explosion.
