Four ways to extinguish fire and six ways to escape

Judging from the fire statistics, most of the fires are caused by people's lack of due fire awareness and necessary fire fighting knowledge. Many people lack the minimum fire extinguishing ability. And did not understand how to organize escapes and self-rescue, resulting in small fires causing catastrophes and serious consequences. Therefore, in the content of "one meeting and two meetings" in fire propaganda, in addition to requiring the masses to keep the fire escape passage open, they also need "two meetings", which will extinguish the initial fire and save themselves.

So, what is the correct way to extinguish the fire? There are four common fire extinguishing measures:

First: suffocation
That is, appropriate measures are taken to prevent air from entering the combustion zone, so that the burning substances are extinguished due to lack of oxygen or cut off.

Second: inhibition method
The chemical fire extinguishing agent is sprayed into the combustion zone to participate in the combustion reaction to terminate the flame reaction and stop the combustion reaction.

Third: Quarantine
Isolate or evacuate combustibles and nearby combustibles to stop combustion. This method is used to extinguish various solid, liquid and gas fires.

Fourth: cooling method.

Spray water or fire extinguishing agent to the burning point of the fire site to reduce the temperature of combustibles below the burning point, thereby stopping the combustion. Generally speaking, the most commonly used methods for extinguishing household fires are suffocation and isolation.

At the same time, with regard to the relationship between the escape of the fire site and the size of the fire, the time of the fire, the height of the floor, and the firefighting facilities in the building, the expert reminded that the fire escape depends on the victims' self-help, mutual rescue ability and escape knowledge. Among them, if the masses want to escape from the danger of fire, they usually have to master several methods of self-rescue to escape in their daily lives.

The first move: keep your head calm
After a sudden fire, panic is the deadliest weakness for those trapped in the fire. Keeping a clear head and thinking calmly is the key to making a good escape self-rescue method and quick response. When we find a fire, we can use self-implication, take a deep breath, and meditate slowly and monotonously on the following words and sentences several times, "I feel very relaxed", "The whole body is relaxing", "Do not panic, I will escape", " I feel good and very calm "until the tension is eliminated.

The second measure: Decisive escape
When the fire is large and exceeds your own fighting ability, decisive escape is the key. When escaping, close the door at will, so as to control the fire and prolong the escape time. Then, from the direction of the back fire, follow the evacuation instructions and quickly leave the fire from the nearest safe passage. If there is a fire outside the room, if you are in the room, try the door handle or the door panel before opening the door to check the fire. If it is cold, you can open a small slit in the door and check the external conditions before choosing the escape plan.
When there are many evacuees, everyone must obey the order and evacuate from the fire in an orderly manner. Do not scramble and crowd each other. Otherwise, it may cause trample on each other and cause an unimaginable tragedy. When escaping, remind everyone not to take the passenger-carrying elevator, because in a fire situation, people taking the elevator may also be caught in a new dangerous dilemma at any time because the elevator is powered off.

The third measure: Zhi Chong smoke area
When escaping from the fire site must pass through the smoke area, it is best for the evacuees to wear gas masks. If there is no gas mask on the scene, we can also take materials on the spot, wet the towel with water, fold it up, cover the nose and mouth, and also act as a smoke prevention effect. At the same time, whether wearing a gas mask or covering your mouth and nose with a wet towel when escaping, in the thick smoke area, because the thick smoke carries heat up, the smoke close to the ground is often the least harmful, Therefore, you should bend down and lean down as much as possible, hold the wall by hand, and crawl on the ground when necessary to reduce the smoke.

Fourth move: rush out of the fire belt
When the fire escape must pass through the fire zone which is not too violent, we can no longer rush in an unprotected situation, otherwise it is no different from the self-jumping fire pit. In order to avoid being burned by fire as much as possible, before we rush over the fire belt, we can first wet our coats, shoes and socks, and then cover the whole body with the spilt quilt or blanket, and brave ourselves, hold our breath, and quickly You can also escape successfully by dashing across the fire zone decisively.

Fifth measure: Escape to the rooftop
When the upper and lower evacuation passages are burnt down or blocked by smoke and fire, if you can run up the evacuation stairs to the rooftop of the building, it is also an opportunity to escape. Here, you can wait for the rescue of the ladder truck in high-rise buildings. While escaping, we can also wait for the rescue of the helicopter.

Sixth trick: use self-made rope to save yourself
When you need to escape from the fire, it is best to use a special rope for self-rescue. If there is no rope, the self-rescuer can also tie the cloth, bed sheets, quilt, curtains, etc. together firmly. After forming a rope, you can tie one end of it to indoor weights, table legs, solid windows, etc. In a place that can bear weight, catch people or slowly drop them down by themselves You can wear gloves when you do n’t have gloves, and you can replace them with clothes and towels to prevent your hands from being injured by the rope.
