Use with caution! The "artifact" that cools down in one second is actually a "walking gas tank"
Some cooling sprays indicate that their main ingredient is LPG, which is mainly composed of propane and butane.
The working principle of cooling spray is to store these flammable and explosive gases in metal tanks through pressurized liquefaction. After being sprayed out, they quickly vaporize and absorb the heat of the surrounding environment to achieve rapid cooling.
In addition, some cooling sprays add methyl ether, which is also a flammable and explosive gas and contains neurotoxicity. Inhaling large amounts can easily cause suffocation.
Once the flammable and explosive gases in the cooling spray encounter an open flame or heat source, there is a danger of combustion and explosion.
When using cooling spray, be sure to eliminate sources of fire, use it with caution in a confined space, and do not spray directly at an open flame.
The working principle of cooling spray is to absorb heat from the air and the surface of objects to achieve a rapid cooling effect. Some products can lower the local temperature below 0°C. If sprayed directly on the body or even skin, it may cause frostbite.
Even if there is no open flame, there is a huge risk in leaving cooling spray in the car during hot weather. After exposure to the sun, it is likely to overheat and cause an explosion.
Therefore, firefighters advise car owners to use physical methods such as sunshade reflectors or parking under the shade of trees to safely cool down their vehicles in summer.
Beware of the "cooling tool" becoming a "hurting weapon"
