The danger of hydrogen balloons
As early as 2006, the relevant departments of our country expressly stipulated that it was strictly forbidden to fill hand-held hydrogen balloons in public places. Helium should be used to inflate balloons. But at present, most vendors selling balloons in the market still sell hydrogen balloons because of the low cost of hydrogen.
The reporter learned that the price of helium is 5- 10 times higher than that of hydrogen, which leads many businesses to choose hydrogen instead of helium. There is a hydrogen balloon about 5 yuan on the market, and a helium balloon of the same size is 20-25 yuan. "Balloons filled with hydrogen are actually dangerous goods. If you are not careful, it may explode due to static electricity or open flame. "
Quanzhou fire related personnel said that ordinary citizens know less about hydrogen balloons, but hydrogen balloon explosions are common, so we must be vigilant. Parents should not buy hydrogen balloons for their children in case of accidents.
