New Year's Eve
Many friends will choose to release balloons
to add a little sense of ritual to welcome the New Year
Be careful, though
Such a seemingly romantic little gesture
There may also be a hidden danger!
In the early morning of January 1, 2024
Wuhan Jianghan Road Pedestrian Street, the New Year's Eve moment is coming
Tens of thousands of people collectively released a large number of balloons
A hydrogen balloon touched the high-voltage line twice and caused a deflagration!
Video display
The scene has been crowded on Chinese New Year's Eve and filled the entire Jianghan Road
Mostly young faces
When the balloons are released, the sky is full of colors
Suddenly there was a flash of fire, followed by two thuds
There were exclamations from the crowd......
Balloon release on Chinese New Year's Eve
It's a romantic thing
But if you don't pay attention, it can lead to disaster
A New Year's Eve celebration in Guangzhou
Similar accidents have occurred
On December 30, 2023, in Guangzhou, Guangdong, when a square was carrying out an iron flower activity, the scattered sparks and the hydrogen balloon in the crowd caught fire after contacting, and the crowd at the scene fled in all directions, and the activity was suspended on the spot. The officer in charge of the plaza responded: Verification is underway to see if anyone has been injured as a result.
The hydrogen in a hydrogen balloon is a flammable gas
When it encounters static electricity or ignition sources, it will explode
life, unextinguished cigarette butts, etc
will cause a hydrogen balloon explosion
Let's go through the following set of experiments
to learn about the dangers of a hydrogen balloon explosion
Experiment 1: Toothless saw spark contact with hydrogen balloon
After the firefighters put on the protective clothing, they used a toothless saw to cut the steel plate to create sparks, and the sparks splashed on the surface of the balloon, and within three seconds, the balloon exploded.
Experiment 2: Simulating cigarette butt lighter contact with a hydrogen balloon
When the firefighter touched the hydrogen balloon with a cigarette butt, the hydrogen balloon was burned out of a small opening, and the internal gas slowly leaked out, and then when the firefighter approached the hydrogen balloon that had been burned by the cigarette butt with the lighter in his hand, the balloon instantly turned into a raging fire.
Experiment 3: Simulate the lethality of a hydrogen balloon explosion in a confined space
The firefighters put the doll and the hydrogen balloon into the box at the same time, and then threw the lit waste paper into it, and soon heard a "bang" sound, and the flames rushed out of the box.
Hydrogen balloons are "on fire".
If you accidentally encounter an open flame
It may bring harm to the people around you
Learn what caused the hydrogen balloon to explode
Let's learn Xi together
Prevent it from "burning" before it "burns"
