Use with caution! The "magic weapon" that cools down in one second is actually a "walking gas tank"

The weather is getting hotter

Many car owners are troubled by this.

After being exposed to the sun, the car turns into a "steamer" in seconds

Sitting in it is like taking a sauna

Therefore, many people are attracted by the cooling spray

Shake and spray

Cool down in one second, refrigerate quickly

However, there are many hidden dangers when using such products

One second cooling, 0 harm?

The truth is...

Some cooling sprays are marked as having LPG , or liquefied petroleum gas , which is mainly composed of propane and butane.

The working principle of the cooling spray is to store these flammable and explosive gases in a metal tank through pressurized liquefaction. After being sprayed out, they quickly vaporize and absorb heat from the surrounding environment to achieve rapid cooling.

In addition, some cooling sprays contain methyl ether , which is also a flammable and explosive gas and contains neurotoxic substances . Inhaling large amounts of it can easily cause suffocation.

The safety hazards of flammable and explosive gases + toxic gases "cooling artifact" cannot be ignored

Just shake and spray to cool down?

Beware of the dangers behind the coolness!

Do not expose cooling spray to open flames

The flammable and explosive gases in the cooling spray are at risk of burning and exploding if they come into contact with open flames or heat sources.

When using cooling spray, be sure to eliminate fire sources , use it with caution in confined spaces , and do not spray directly at open flames.

Do not allow cooling spray to come into contact with skin

1. Avoid burns

2. Prevent frostbite

The working principle of cooling spray is to absorb the heat from the air and the surface of objects to achieve a rapid cooling effect. Some products can reduce the local temperature to below 0°C, but if sprayed directly on the body or even the skin, it may cause frostbite.

Do not place in the car in direct sunlight

Even if there is no open flame, there is a huge risk of leaving cooling spray in the car during hot weather, as it is likely to overheat and explode after being exposed to the sun.

Therefore, firefighters recommend that car owners use physical methods such as sun visors or parking in the shade of trees to safely cool down their vehicles in the summer.
