6 potentially explosive objects right next to us

Even if they are small items, they are really "slow-bombs", causing damage to your life.

At about 15:30 this afternoon (March 19), a sudden explosion occurred in a low-rise building in Van Phu Urban Area (Ha Dong, Hanoi), causing many casualties. Many people believe that a terrible explosion came from 4 to 5 km away.

Many witnesses believe that this is a gas explosion, or oxygen tank . so there is such scary power.

Although the authorities are still searching for the cause of the explosion, there is a fact that there are quite a few "slow explosive bombs" around us that you need to know to prevent.

1. Gas cylinders

Gas cylinders are one of the leading causes of big explosions.

Gas stove is considered a popular item in the kitchen of many families. However, this is said to be one of the leading causes of big explosions.

Be aware that gas tank explosions are mainly due to gas leaks. The gas itself cannot cause explosion.

Gas tank explosions are mainly due to gas leak.

Explosive principle is because the gas combined with oxygen in the air forms a fire mixture and only needs to be in the appropriate high temperature or sparks emitted when turning on the lights, fans, phones, high shoes Metallic heels follow the floor . it is very easy to explode.

2. Lighters

Lighter is a potential source of explosion that few people notice.

Lighters are familiar to many men, but they are a potential source of fire that few people notice.

Specifically, in the gas lighter contains a certain amount of gas, when the gas in the lighter is leaked (due to cracked plastic cover, open valve .) to the surrounding environment (with oxygen), meet the heat environment High enough or sparking (albeit very small) can cause explosion and damage to users.

3. Battery, backup charger

Your phone's battery, backup battery is an electrical device used to power your main battery.

Many airlines give ban on carrying batteries, charging in checked baggage to avoid the risk of explosion.(Illustration).

The general structure of energy batteries, in particular here is a cell Lithium-ion battery is made up of many plates carrying opposite charges stacked on top of each other and separated by insulating layers.

But because 2 opposite electrodes are separated only by a thin insulating plate, in special cases, these plates are broken and the charge is directed through the opposite plates, the whole battery will heat up. fast and explosive.

Because of that, many airlines have issued a ban on carrying batteries, charging backup in checked baggage to prevent the risk of fire and explosion.

4. Refrigerator

It may sound strange, but this is actually a slow bomb in your home. Be aware that the structure of the family refrigerator includes indoor units, outdoor units, gas cylinders, compressors, pipes . in which gas cylinders have the function of pumping gas to the indoor unit for the cooling process.

The risk of refrigerator explosion is common in cabinets that are too old or repaired by welding, replacing gas many times .

Compressor helps gas circulate in the refrigerator; When the refrigerator operates the compressor, it will transfer gas in the form of gas to liquid form and bring the circulating gas to cool throughout the machine.

The risk of refrigerator explosion is common in cabinets that are too old or repaired by welding, changing the gas many times so that there are clogged clogs connecting the condenser to the evaporator, reducing cooling capacity, leading to pressure The system capacity is too high, easily explosive.

In addition, there are cases when the voltage suddenly increases, the compressor continuously brings gas to the outdoor unit, increasing the pressure of the gas, leading to fire.

5. Perfume

In perfumes containing alcohol content - this is a more easily flammable ingredient.

Perfume is an explosive material? Many of you will feel silly, but the truth is that this is a time bomb when you leave them in cars or in high temperatures.

In perfumes containing alcohol content - this is a more easily flammable ingredient. If accidental perfume bottles are in the form of convex lenses in the car and are exposed to the sun, producing a focal point will burn the alcohol inside, easily creating a serious explosion.

6. Mini fire extinguisher

We know that mini fire extinguishers are "patron gods" , indispensable items in every car. But if they are not preserved properly, they can be completely counterproductive and become a "slow-detonating bomb" that is dangerous to your life at any time.

Mini fire extinguishers are usually in powder form - are internal N2 fire extinguishers as propulsion to spray powder to extinguish the fire.

Fire extinguishers should be stored in a cool place with a temperature not exceeding 55 ° C.

However, all kinds of fire extinguishers must be stored in cool conditions, avoid being near high or outdoor temperatures, the appropriate temperature from -10 degrees Celsius to 55 degrees C.

If the temperature is too hot, such as direct absorption of the heat from the Sun can increase the volume of the flask, the liquid inside the tank increases. When the pressure threshold is large enough, it will cause an extremely dangerous explosion.
