A few days ago, Lao Wang and his son, who lived in Baimao Town, Changshu City, Jiangsu Province, were suddenly exploded when they took down the balloon that floated to the tree in front of their house. Both father and son were burned. According to the fragments of the balloon after the explosion, the family said that the source of the hydrogen balloon was Jiading, Shanghai. The reporter was informed that at present, relevant departments have investigated the source of balloons.
The balloon hung across the tree head and suddenly exploded during pulling.
On the afternoon of August 1st, a balloon floated from mid-air, which broke the quiet life of Lao Wang’s family in Baimao Town, Changshu City.
"This balloon should have suddenly floated to the village around noon. The balloon was hanging at the door of Wang Hu’s house. When he saw the balloon hanging on the tree, Wang Hu tried to move it with his son. I didn’t expect the balloon to explode during the movement. The fire suddenly caught them both." Wang Hu’s relatives told reporters.
After the accident, the injured Lao Wang and his son were sent to Changshu First People’s Hospital. After examination by the hospital, the burn area of both of them is about 30%, which is a second-degree burn. Photos sent to reporters by the families of the injured showed that the faces of the injured father and son were burnt black, and their limbs were burned to varying degrees, wrapped in thick gauze.
Balloon fragments and victims
According to family members, after treatment, at present, the two injured people are out of danger. It is understood that the 41-year-old Wang Hu and his 17-year-old son Wang Peng were living by growing vegetables at home.
The balloon trademark is suspected to be a shopping mall in Jiading, and the specific source is still to be investigated.
According to the account of the families of the injured, the diameter of the balloon that exploded was about 2 meters, and the surface was yellow with the words "Taibei Hot" printed on it. Family members said that they suspected that the balloon that exploded or the "Taipei Style Street" shopping mall in Jiading District of Shanghai.

According to the clues provided by the families of the injured, the reporter came to the shopping center and found that the trademarks outside the shopping mall were almost exactly the same as those on the wreckage of the exploding balloon. A merchant operator in the mall revealed that the mall began trial operation on April 30 this year and officially opened on July 30. On the opening day, balloons with similar slogans like "Taibei Hot" were hung outside the mall. The above statement was also confirmed by other staff in the mall. The staff all recognized the trademark on the photo of the exploding balloon as the trademark of the mall, but most of them said they couldn’t remember whether the mall had used similar yellow balloons when it opened.
The reporter tried to interview the management of the mall on related issues, but the front desk staff said that the leader of the planning department of the mall was not in class, so it was not convenient to respond to related questions.
The linear distance between Baizhen and the shopping mall in Changshu City, Jiangsu Province is about 50 kilometers.
Looking through the map, the reporter found that the linear distance between Baizhen and the shopping mall in Changshu City, Jiangsu Province is about 50 kilometers. At present, relevant departments have investigated the incident, and where the balloon belongs and how it floated to Changshu need further confirmation from relevant departments.
Authority: Balloons should replace hydrogen with inert gas.
According to the family members of the injured, Lao Wang and his son did not smoke at the time of the incident. When pulling the balloon, there was no fire source nearby. I don’t know why the balloon suddenly exploded.
The data show that hydrogen is a flammable and explosive gas, which is not easy to react with oxygen at room temperature. However, when it is in a closed space, because it is mixed with air, once the concentration is too high, it will react to generate heat. Because the heat cannot be discharged, the pressure will expand rapidly, and when it exceeds the surface load of the balloon, it will explode.
Official website, China Meteorological Bureau, issued the Notice on Further Strengthening the Safety Management of Balloon Releasing in June 2008. The notice showed that in order to avoid the accident of explosion and personal injury after the balloon landed, tethered balloons released in densely populated areas (referring to balloons that are tied to the ground winch by cables and can control their floating height in the atmosphere) should be filled with inert gas instead of flammable and explosive gases such as hydrogen.
According to the "Measures for the Administration of Balloon Flying", if it is really necessary to fly balloons in large-scale activities approved by the government at or above the county level, in addition to the normal procedures for examination and approval, the security forces and measures of balloon flying units and activity organizers should be strictly reviewed, and on-site supervision should be strengthened to ensure the safety of balloon flying activities.
According to insiders, the inert gas helium is the second least dense gas after hydrogen. Helium is an ideal balloon filling gas because it is not flammable. However, in the actual circulation, the price of helium is more than ten times different from that of hydrogen. In order to save costs, it is not excluded that some businesses take the risk to choose hydrogen balloons. "In addition to being directly ignited, static electricity, sun exposure, high pressure, etc. may also cause hydrogen balloons to explode." The above-mentioned insiders introduced this to reporters.
