Fire safety 8 life-saving fire cold knowledge

First, the main cause of death in fire is not fire.

In film and television dramas, we often see such a picture-the house is on fire and the protagonist screams in panic: "Ah! Fuoco! Help! "

In fact, this is very dangerous, because the main cause of death in a fire is not fire, but smoke. According to statistics, more than 80% of fire deaths are caused by smoke choking, and the number of people choking with smoke is 4-5 times that of burning!

Shouting so loudly in the smoke may inhale more toxic gases, and you may have been unconscious in the smoke before calling anyone.

Second, don't look for wet towels after the fire.

In the traditional fire escape, we need to find a towel to cover your nose and mouth to stop the smoke, but this may put you in danger first. At present, the burning of home decoration materials is accompanied by a lot of toxic smoke, and the effect of wet towels is not obvious. In addition, spending time looking for wet towels in precious escape time may miss the opportunity to escape.

The correct way should be "small fire runs fast, smoke closes the door", especially in case of fire and smoke, you should immediately close the door to block smoke, and at the same time run to the balcony or window for help, waiting for firefighters, instead of rushing out blindly.

Third, don't hide in the bathroom or bathroom and wait for help.

When there is a fire, many people think it is right to hide in the bathroom, toilet and other places with water. However, in reality, there have been many tragedies of being killed hiding in the bathroom.

In fact, bathrooms and toilets generally occupy a small area and are prone to lack of oxygen. If there is no outdoor window inside, once the door is burned through, high temperature and smoke will bring greater danger after pouring into the narrow space!

Of course, the hiding place in a fire should not be named, but should be decided according to its nature, that is, the place should be large and ventilated, so that people can easily find you.

Fourth, take off your stockings when you escape from the scene of the fire.

Silk stockings are easy to ignite, and once they catch fire, they are terrible! One program did an experiment of burning socks. Even thick stockings burn quickly. If there is an open flame, burnt high-temperature substances will be left on the legs to continue burning. So, when you escape from the fire, take off your stockings first!

Here, I would also like to remind female friends not to wear stockings when going to places prone to fire such as outdoor barbecues.

In case of fire, touch the door handle before opening the door.

Touching the door handle is to know the fire outside. If it feels very hot, it means that the corridor outside is full of life-threatening heat, and it is too late to open the door to escape. If the door is not hot, you should open it very carefully. You should hold the door tightly with your body or feet first, and then open the door bit by bit. If you feel pressure or heat wave, you should immediately close the door, turn to the window for help or take other self-help measures.

In short, remember, don't rush out when there is a big fire outside. Rushing out is equivalent to killing yourself.

6. It is wrong to escape upward when a tall building is on fire.

Should high-rise buildings run up or down when they escape from fire? This question is often confusing, and the fire police say it is wrong to escape upwards!

The most dangerous thing in the fire scene is smoke. When fireworks invade the stairwell, the "smoke effect" will make the smoke spread upward quickly, and escaping upward will often make you faint or even die. When the fire is too big, you should try to stay in the open places that are easy to be found, such as balconies and windows, and wait for rescue.

Seven, fire extinguishers also have a shelf life.

Yes, fire extinguishers also have a shelf life. Expired fire extinguishers not only affect the use, but also may explode!

Therefore, you must pay attention to check whether it is effective. There is a pressure gauge on the fire extinguisher. When the pointer of the pressure gauge points to the red part, it means that the pressure in the bottle is not enough and the fire extinguisher cannot be used normally. When it refers to the yellow part, it means that the pressure is too high and it is easy to be dangerous; When it points to the green part, the fire extinguisher is normal.

Eight, the fire police are free.

Don't laugh when you see this, because many people really don't know! Remember, it is important to say it three times: no charge, no charge, and no charge for fire brigade rescue.
