Flammable and explosive! Don't leave these things in your car in the summer, or they will become a "time bomb"

Hot, hot, hot, the weather is so hot lately that it's melting...

If "fried eggs on the pavement" and "roasted raw garlic on the balcony" can barely be considered as finding joy in misery, today's hot search is definitely heart-wrenching:

What's going on?

It turns out that in hot weather, the temperature inside a car can reach over 60°C under direct sunlight. In addition, many people choose dark colors for car interior decoration in order to avoid looking dirty. In summer, dark colors absorb heat and are so hot that they burn your hands.

In this closed "furnace" environment, many small items that are usually placed casually in the car become "explosive items" which can easily cause the vehicle to catch fire if not carefully checked.

Friends who have cars, please check the list below to see if you have them in your car. If so, take them away quickly.

1. Car perfume

The main component of perfume is volatile gas. If the bottle mouth is sealed, it is easy to explode in a high-temperature space due to the expansion of gas and the inability to discharge. In addition, the alcohol content is extremely high, making it very flammable.

Pay special attention to perfume bottles made of crystal or glass. When exposed to the sun, they can create a focusing effect similar to a magnifying glass. If the light happens to focus on paper or other flammable items, the consequences can be disastrous.

2. Lighter

The main ingredient of ordinary lighters is liquid butane, which is flammable and explosive.

Once the ambient temperature exceeds 55°C, the gas in the lighter will expand due to the heat. The temperature of a vehicle that has been exposed to the sun is much higher than this, which can easily cause an explosion.

3. Disinfectant alcohol

Because of the epidemic, many people are accustomed to putting a bottle of disinfectant alcohol in the car for timely disinfection, but alcohol is flammable and needs to be stored in a cool place away from light. It is not suitable to be placed in a car that is easily exposed to direct sunlight.

4. Carbonated drinks

Carbonated drinks contain gases such as carbon dioxide. If you shake the bottle slightly, there is a risk of "breaking the bottle cap". When the temperature in the car rises, it is easy to expand and cause an explosion, which is dangerous. It is best to buy and drink it immediately.

5. Canned spray

The reason why canned spray can spray out the liquid in the can is because the pressure inside the can is very high. If it is exposed to the sun in a car, the pressure will rise sharply and may exceed the pressure resistance of the can and explode, and the power of this explosion will be very large.

So try not to leave things like hair spray, aerosol fresheners, and pump-type sunscreen in your car.

6. Power Bank

Power banks, batteries and other products may swell and explode if left in a car with high temperature for a long time. Especially some inferior power banks use unqualified lithium batteries or modified batteries, which will have worse stability.

7. Reading glasses

Reading glasses are convex lenses, which can easily gather light like a magnifying glass. In order to make them easier to take, we often put them on the center console rack in front of the car window, which makes it easier to focus light, causing the focal point temperature to be too high, which may burn out the plastic trim inside the car and even cause the vehicle to catch fire.

In addition to the above, there is one more important point: children!

In the past summers, there have been many tragedies where children died due to parents locking them in cars due to negligence.

Therefore, when you go out for a trip, please be sure to look after your children. Never leave your children alone in the car with the fluke mentality that “you are just going out for a while and will be back soon”, otherwise it will be too late to regret.
