CCTV News:At present, a "online celebrity balloon", named Bobo Ball, is selling well on the street, which is highly sought after by children and couples. And just recently, this "online celebrity balloon" exploded:
When a man was smoking, he accidentally spilled sparks on the balloons, and all six balloons exploded.Four people were burned to varying degrees, and the most serious was second-degree burns.
Balloon exploded and 4 people were burned.
The structure of luminous balloon is very simple, and its components include a transparent balloon, a string of colorful LED strip and two batteries. Although "beautiful in appearance", there are certain security risks.
A few days ago, four people were injured by online celebrity balloon, and two of them were badly burned. The 26-year-old Mr. Zhao (changed his surname) still has a lingering fear when he recalls that scene.
He said that after a group of four people had finished their meal that night, they saw someone selling such balloons on the road. They thought it was 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, when these people arrived, they all had different degrees of burns, two were slightly injured and two were seriously injured. Mr. Zhao is the most seriously injured, and the initial diagnosis,His face and limbs were burned to the second degree.The specific injury needs further diagnosis; There is also a woman with burns on her face.
Network hot-selling filling gas is unknown
The reporter found in some online shopping platforms that this kind of luminous balloon, also called "bobble ball", is also very popular in online sales, and many shops have sold tens of thousands of pieces. The price is very cheap, and the ordinary model includes a wave ball, a LED strip and three batteries, and the price is 5-8 yuan.
As for what gas is filled in the balloon, vendors have different opinions, some say it is hydrogen, and some say it is helium. There are also many shops that directly indicate that it is safe to use air instead of helium.
According to the investigation, a 13-liter helium tank needs 72 yuan, which can fill 15-17 balloons. On average, each balloon costs about 5 yuan.And 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 balloon burning and explosion in the past, butNow, for the sake of safety, generally speaking, balloons are filled with helium.Helium is an inert gas, which is relatively safe.However, it is not excluded that some vendors use hydrogen instead of helium in order to save costs.
Hydrogen is flammable and explosive, andHydrogen balloons and helium balloons are difficult to judge from the appearance.Judging from the description of the explosion power of this balloon by the injured, it is likely that the balloon they bought was pretending to be helium with hydrogen.
Has been issued a consumer warning by the European Union.
As early as March this year, the European Commission’s non-food rapid warning system (RAPEX) issued a consumer warning to balloon toys with LED lights of unknown brands made in China.
The reason for this warning is expressed by the EU as follows:
“The product is at risk of chemical, asphyxiation 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;The product does not meet the requirements of toy safety directive and related European standard EN 62115."
Measured the power of "online 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 Burning with an open flame gives off a pungent smell.
First, firemen simulate what might happen when the bobo ball meets an open flame.
The reporter saw thatThe balloon was ignited at the moment when it touched the open flame of the lighter.The burnt drips on the table continue to burn and catch fire, and turn into black glue with obvious pungent smell.
“The burning of this substance will produce toxic gas, which will cause burns to people’s respiratory tract, and once the dripping directly touches the skin, it will cause burns to the skin.Fang Chen, the squadron leader of Yuquanying Fire Squadron in Fengtai District, said.
Experiment 2 Drops 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 thatDrops dripped on the wool hat, and the surface quickly burned and burned through.The fiber on the surface of the hat has been burnt black, and on the other hand, the inside of the hat has been burnt through by black glue.
Fang Chen said that this situation is very dangerous and will cause serious burns to the skin on the head surface.
The fire department reminds:
△ When buying such balloons, be careful not to choose those containing hydrogen, helium and other combustible gases;
△ Secondly, carefully check whether there are cracks on the surface of the balloon and the connection point, and you must 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.
