This is really a "hot" down jacket

but

More netizens are still worried

“Are there any people injured in the explosion?”

How can a down jacket explode?

Why do down jackets explode?

Fluffy and soft down jacket

There is such an "explosive" side

It’s too insecure!

So, for no reason

How could a down jacket suddenly explode?

It turns out that in order to prevent down from penetrating, many down jackets are made of special coatings, which results in the down jackets themselves being less breathable than ordinary clothing. When a down jacket is suddenly expanded under pressure, the squeezed gas cannot be quickly discharged through the less breathable lining and can only be discharged from the relatively breathable seams or quilting. The high-pressure gas wraps the down and breaks through the loose seams and spurts out from the bursting point, thus causing the "explosion" phenomenon on taxis.

However, those wearing down jackets in front of the screen do not need to worry too much, as experts point out that this is a relatively extreme situation. If a down jacket is inflated, it will form a balloon-like shape. "If the air permeability is poor, we press it quickly, or stir it at high speed, it will easily explode like a balloon. If the air permeability of the down jacket is relatively good, the air will be quickly discharged when it is squeezed. In this case, it will not cause an explosion."

Safety hazards of down jackets

You must know

Wearing a down jacket and encountering open flames: You will catch fire!

The fire department once conducted an experiment on a mannequin. They put a down jacket on the mannequin and zipped it up. They used a lighter to light a corner of the hem of the jacket. Flames immediately burst out of the jacket, and the fire gradually expanded and spread. In less than 5 minutes, the entire down jacket was burned to ashes, and even the zipper was completely melted.

Firefighters said that if the down jacket is worn by a person and comes into contact with oily skin, it may burn faster: "If a down jacket is worn on the body and catches fire, the person will run and generate wind, which will also accelerate the burning speed of the clothes."

Special reminder

When wearing down jackets, you should stay away from open flames as much as possible. If your body catches fire, you should take off your clothes in time and put out the fire. If you cannot take off your clothes in time, you should protect your face with your hands and roll on the ground.

Wearing a down jacket in the kitchen: It may explode when exposed to carbon monoxide!

On January 4, 2018, an old man in Lishui, Zhejiang was tidying up in the kitchen when his down jacket suddenly exploded, leaving several big holes on the back of the clothes!

It turned out that the down jacket exploded because of a gas leak in the kitchen. The carbon monoxide reached a certain concentration, and the friction between the down jacket and other objects generated static electricity, which caused the down jacket to suddenly explode.

Special reminder

Be careful when wearing a down jacket to places where there is a risk of static electricity, such as kitchens and gas stations where there may be gas leaks.

Spinning a down jacket in a washing machine: It may explode!

Putting down jackets in the washing machine to dry may also cause explosions. In recent years, there have been many cases of washing machine explosions.

On January 23, 2018, a resident in Shenyang City, Liaoning Province, turned on the washing machine at home, but the washing machine exploded shortly afterwards. The reason was that the resident used the washing machine to wash a down jacket.

On November 21, 2021, a woman in Shangqiu City, Henan Province put her down jacket into the washing machine to spin dry after washing it. A few seconds later, the clothes and the machine exploded.

On February 14, 2022, a woman in Ji'an, Jiangxi Province washed her down jacket by hand and then put it into the washing machine to dehydrate. A few seconds later, the clothes and the machine exploded.

It turns out that down tends to clump together when washed, and the coating on the surface of clothes that prevents the down from protruding is not conducive to the timely discharge of the air inside. So during the dehydration process, the down expands rapidly, exceeding the volume of the machine and causing an "explosion."

In addition, static electricity caused by friction between the down jacket and the inner tank of the washing machine during high-speed drying may also cause an "explosion".

Special reminder

Down jackets should be hand washed or dry cleaned as much as possible. It is best not to use a washing machine, especially the spin drying step.
