21 Ways to Escape Self-protection in Fire

  1. How to use the dry powder fire extinguisher: Use the same method as the carbon dioxide fire extinguisher, but it should be noted that before using the dry powder fire extinguisher, the fire extinguisher should be turned upside down several times to loosen the dry powder inside the cylinder. When using ABC dry powder fire extinguishers to fight a solid fire, the fire extinguishing nozzle should be aimed at the place where the combustion is most intense, sweeping it from side to side, and the dry powder fire extinguishing agent should be sprayed evenly on the surface of the burning material until the fire is completely extinguished. Due to the cooling effect of the dry powder, fire must be prevented after the fire.

2, after the household appliances caught fire, the method of fighting:

1 Immediately shut down, dial down the power plug or pull down the main gate. If only electric sparks are found, the fire will self-extinguish after the power is turned off. 2 If the wire insulation and the electrical enclosure and other combustible materials catch fire, use a wet quilt or other covering to seal the fire. 3 Do not use water to prevent it from causing damage to the TV's tube. 4 Never use the power supply without repair to avoid electric shock and fire accidents.

3, the computer fire rescue method: If the computer caught fire, even if you turn off the machine, or even unplug the plug, the machine's components are still very hot, will still produce flames and produce poisonous gas, fluorescent screen, picture tube may also explode, the response method is: When the computer begins to smoke or catch fire, immediately unplug the plug or turn off the main switch, then cover the computer with a wet carpet or quilt, etc. This will not only prevent the spread of smoke, but also block the glass fragments of the screen. Do not splash water on the fire-fighting computer, even if the computer has been turned off, because the sudden drop in temperature can cause the hot cathode-ray tube to burst. In addition, there is still residual current in the computer. Water splashing may cause electric shock. Do not lift the cover to watch. When the fire is extinguished, the computer must be accessible from the side or behind to prevent the explosion of the tube.

4. To prevent fires occurring at home must be done:

(1) Do not connect to the power cord by yourself. (2) Don't throw cigarette butts. (3) Do not lie in bed and smoke. (4) Do not read candles in mosquito nets. (5) Do not incinerate sundries, and point mosquito coils should take effective fire prevention measures. (6) Do not store flammable or explosive materials. (7) Do not use high-power electrical appliances such as heat fast, electric stoves and air conditioners, and do not use electric blankets, inferior electrical appliances, etc. that may cause fire. (8) Do not use alcohol stoves, liquefier cookers to cook on fire. (9) VIPs go out of power. Smell the smell of wire and rubber, report it promptly and take measures. (10) Lamps do not lie close to pillows and bedding.

5, the correct use of "119" phone: when the police, first of all calm, do not panic, one should be clear about the fire unit, address, burning objects, fire situation, and the alarm person's name, where the phone number to the fire brigade, For contact. After the alarm, I or send people to the intersection of the road to the fire to meet the fire engine; second, early warning, fighting for fire fighting time, reduce losses.

The telephone number of the alarm help service is: Fire: 119

6. The causes of fire accidents include: arson, electrical, illegal operations, careless use of fire, play with fire, smoking, spontaneous combustion, lightning strikes, and other factors such as earthquakes, windstorms, etc.

7. Fire: A burning phenomenon that loses control and causes some damage in time and space. It is called a fire.

8, according to the combustion of materials and characteristics, the fire is divided into A, B, C, D four categories:

Class A refers to combustible solid matter fires; Class B refers to liquid fires and melted solid matter fires. Category c refers to combustible gas fires; Category D refers to combustible metal fires such as potassium, sodium, magnesium, titanium, lithium, aluminum alloys, etc.

9. Different fire extinguishing agents should be selected according to different types of fires:

1 The use of water, foam, and ammonium phosphate dry powder extinguishing agents should be used to save Class A fires. 2For extinguishing Class B fires, dry powder and foam extinguishing agents should be used. Do not use chemical foam fire extinguishing agents or anti-solvent foam fire extinguishing agents to fight polar solvents in Class B fires. 3 The use of dry powder and carbon dioxide fire extinguishing agents should be used to save Class C fires. 4 Use 7150 fire extinguishing agent and sand, soil, etc. for fire fighting Class D fire.

10. Doors and windows cannot be easily opened in the event of a fire: As the room is closed, the air is not smooth, and the indoor oxygen supply is insufficient. Therefore, the fire develops slowly. Once the doors and windows are opened, fresh air inflows rapidly and the fire rapidly develops; The influx of gas makes it easy for people to become poisoned, suffocate and die. In addition, due to the convection of air, the flames will be pulled out. Therefore, in the event of a fire, doors and windows cannot be opened.

11. Fire escape methods: Generally speaking, fire escape methods mainly include: 1 use climbing fire trucks, two ladders to escape the use of escape; 2 escape through building passages or building facilities; 3 self-made equipment to escape; 4 to find Refuge places to escape; 5 save lives; 6 Use nearby fire-fighting equipment or other equipment to escape while extinguishing.

12. The right method of extinguishing fire on the body: Once the body is on fire, you should first take off your clothes and extinguish the fire; or roll over on the ground and suffocate the fire. But don't scroll too fast and don't run. If there are nearby water sources such as pools, ponds, etc., you can quickly jump into the water, or take water in time to extinguish the body. However, when the body is burned, care should be taken not to jump into the sewage to prevent infection.

13. In the event of a fire, the elevator cannot be evacuated. The reasons for the evacuation of ordinary elevators on the fire site are as follows: First, after a fire, it is often easy to cut off the electricity and cause the elevator to “stuck”, which makes it difficult for the rescue work and affects the timely evacuation. The second is that elevators pass directly to all floors of the building. Smoke from the fire floor can easily cause a “chimney effect” when it enters the lift channel. People will be smothered with smoke and gas and suffocate at any time in the elevator.

14. Self-rescue methods for fire escape: a. In the event of a fire, do not delay precious escapes for clothes and money. Evacuate from safe passages, safe exits, and fire escape stairs as soon as possible; do not blindly smash or use the elevator to escape;

15. The basic principle of fire prevention is to prevent the generation of burning conditions, to prevent the three conditions of combustion from combining with each other, and to take actions that restrict and weaken the development of the combustion conditions and prevent the spread of fire. This is the basic principle of fire prevention.

16, the basic measures for fire prevention are: 1 control of combustibles. Replacing flammable or flammable materials with non-combustible or non-combustible materials; adopt local or total ventilation methods to reduce the concentration of combustible gases, vapors, and dust; and store items that interact with each other chemically. 2 isolate the combustibles. It is to prevent flammable gases, liquids, and solids from coming into contact with air, oxygen, or other oxidizers. Even if there is a fire source, combustion cannot take place because there is no combustion aid. 3 eliminate the source of fire. It is the strict control of open fire, electric fire, and prevention of static electricity and lightning. 4 Stop the fire from spreading. It is to prevent fire or Mars and other sources of fire from entering equipment, pipelines, or spaces that are in danger of burning or exploding, or to prevent the spread of flames in equipment and pipelines, or to restrict combustion to a certain extent so as not to epitaxially burn.

17. The basic principle of fire extinguishing is that according to the basic conditions of combustion, all fire extinguishing measures are to destroy the combustion conditions that have already formed, or to stop the chain reaction of combustion and extinguish the fire and control the fire within a certain range. Reduce fire damage.

18, the basic methods of fire extinguishing are:

The suffocation fire extinguishing method is to prevent air from flowing into the combustion zone or dilute the air with non-combustible substances, so that the burning material can be extinguished by cutting off the oxygen. Such as the use of foam oil fires.

The suppression fire extinguishing method, also called the chemical interruption method, involves the extinguishing agent participating in the combustion reaction course so that the free radicals generated in the combustion process disappear, and a stable molecule or a low-activity free radical is formed to stop the combustion reaction. Such as dry powder fire extinguishing agent gas fire.

Cooling fire extinguishing method is to directly spray the fire extinguishing agent on the burning object, reduce the temperature of the combustible material below the ignition point, and stop the combustion. Extinguish with water.

Extinguishing the fire-extinguishing method is to separate or disperse the burning object from nearby combustible materials, so that the burning stops.

19, commonly used fire extinguishers: foam fire extinguishers, carbon dioxide fire extinguishers, dry powder fire extinguishers.

20, water can not save the fire: 1 alkali metal can not save with water. Because water and alkaline metals (such as metal potassium, sodium) can make water decomposition and generate hydrogen and emit a lot of heat, it can easily cause an explosion. 2 Carbonized alkali metals, alkali metal hydrides cannot be saved by water. Potassium carbide, sodium carbide, aluminum carbide, and calcium carbide, as well as potassium hydride and magnesium chloride, react chemically with water and emit a large amount of heat, which may cause fire and explosion. 3 Lighter than water and flammable liquids that are insoluble in water, in principle no water can be used to save. 4 molten steel, molten steel can not be saved with water. Because the temperature of molten iron and molten steel is about 1600°C, hydrogen vapor and oxygen can be decomposed when water vapor is above 1000°C, causing explosion hazard. 5 Acids (sulfuric acid, nitric acid, and hydrochloric acid) cannot be saved with strong currents. If necessary, they can be saved by spray water. 6 High-voltage electrical equipment fires, in the absence of a well-grounded device or without a cut-off current, cannot normally be saved by water.

21. How to use carbon dioxide fire extinguisher: Pull out the safety plug first, then press down the pressure handle (or swirl the valve), and place the nozzle at the root of the fire to extinguish the fire.

Carbon dioxide fire extinguisher matters needing attention: When using, should wear the glove, in order to avoid the skin from touching the spray tube and spraying the rubber tube, prevent frostbite. When a carbon dioxide fire extinguisher is used to extinguish an electrical fire, if the voltage exceeds 600 volts, it should be extinguished after the power is turned off.
