Question 2: What methods should be used to put out a fire in household appliances? Cut off the power supply, and then do everything possible to isolate the ignition point from oxygen (dry powder fire extinguisher or sand can be used). If the fire spreads rapidly, it is recommended to call 1 19.
Question 3: How to put out the fire when there is a fire at home? 1. Call the fire alarm if you find a fire 1 19. When calling the police, it is necessary to explain the detailed address, fire location, fire substance, fire size, name and telephone number of the alarm person, and send someone to meet the fire truck at the intersection.
Don't panic if the house is on fire. If the fire is not big, you should quickly use the simple fire extinguishing equipment available at home and take effective measures to control and put out the fire.
If the oil pan is on fire, you can't splash water to put out the fire. You should turn off the gas valve of the stove, cover it directly or cover it with a wet rag to suffocate the fire. You can also put the cut vegetables into the pot to cool and extinguish the fire.
4. When the gas tank is on fire, cover it with soaked bedding and clothes to extinguish the fire, and quickly close the valve.
5. When household appliances or lines catch fire, cut off the power supply first, and then use dry powder or gas fire extinguisher to put out the fire. Don't throw water directly to put out the fire, so as not to get an electric shock or explosion and hurt people.
6, don't rush to open the doors and windows when fire fighting, so as to avoid air convection to accelerate the spread of the fire.
Question 4: Home appliances are on fire. How to put out the fire? 1, cut off the power supply in time
If only a few fires are caused by electrical short circuit, you can immediately turn off the electrical power switch and cut off the power supply. If the whole circuit burns down, you must pull down the main switch and cut off the main power supply. If it is too far away from the main switch, it must be removed.
Cut the wire away from the burning place in the right way. Be careful not to pull or cut wires directly with hands or metal tools. Stand on a wooden bench and cut wires with tools such as wire cutters and diagonal pliers with insulated handles. After cutting off the power supply
Fire can only be put out by conventional methods, and it can be doused with water without a fire extinguisher.
2, can't directly wash the appliance with water.
After the electrical equipment is on fire, it cannot be washed directly with water. Because water is conductive, it is easy to get an electric shock after entering live equipment, which will reduce the insulation performance of equipment and even cause equipment explosion, endangering personal safety.
Question 5: If there is a fire at home, is there any quick way to put out the fire? When the oil pan is on fire, you can put a rag and other things on it, quickly take the pan away from the fire source and tighten the lid to put out the fire. If you burn gas or oil and gas, you should close the valve first, and then crush it with the lid. If there are chopped vegetables nearby, you can also throw them into the pot to help put out the fire. If the liquefied gas tank catches fire, you can first block the leaking place with a wet towel. , and put out the fire, and then repair (preferably contact the gas company). If the fire is very big, you should put out the fire with a dry powder fire extinguisher and call the fire brigade at the same time. Clothes, bedding, cotton and other burning things can be doused with water. Gasoline fire can be buried with sand, and it is best to use a dry powder fire extinguisher. Children who catch fire while playing with fire should immediately use local materials to put out the fire. For example, quickly cover the flames with blankets and quilts, and then water them to put them out.
Question 6: The air conditioner at home suddenly caught fire. Which of the following fire extinguishers can't be used to put out the fire? Hello, foam extinguisher has been eliminated. Halon fire extinguishers are only used in petrochemical industry and precision instruments because they will destroy the ozone layer. Because the air conditioner has a large cavity and air circulation, it is easier to rekindle if a dry powder fire extinguisher is used, so it is recommended to use a carbon dioxide fire extinguisher. When a carbon dioxide fire extinguisher is used to put out a fire, carbon dioxide gas can expel air, surround the surface of the combustible or distribute in a relatively closed space, so that the oxygen concentration around the combustible or in the protective space is reduced, and suffocating gas is generated to put out the fire. It is mainly suitable for all kinds of flammable, flammable liquid and flammable gas fires, and can also put out the initial fires of instruments, books and archives, handicrafts and low-voltage electrical equipment. If the indoor air conditioner catches fire, using a carbon dioxide fire extinguisher can effectively control the fire. If it is outdoor, the fire extinguishing effect is poor because there is no closed space. At this time, it is suggested to turn off the air conditioning power supply first, and then use the water gun to extinguish the fire.
If you have any questions, ask them.
Question 7: What kinds of common fires are there? What method is used to classify fire fighting (GB/T 4968-2008 2008, 165438+20091October 4, implemented on April 6, 2009)
Fire scene
According to the types and combustion characteristics of combustible materials, fires are divided into six categories: A, B, C, D, E and F.
Class A fire: refers to solid material fire. This substance usually has the nature of organic matter, and it can generally produce glowing embers when burned. Such as wood, hay, coal, cotton, wool, hemp, paper and other fires.
Class B fire: refers to the fire of liquid or meltable solid substances. Such as kerosene, diesel oil, crude oil, methanol, ethanol, asphalt, paraffin, plastic and other fires.
Class C fire: refers to gas fire. Such as gas, natural gas, methane, ethane, propane, hydrogen and other fires.
Class d fire: refers to metal fire. Such as potassium, sodium, magnesium, aluminum-magnesium alloy, etc.
Class E fire: refers to live fire. A fire in which an object burns with electricity.
Class F fire: refers to the fire of cooking materials (such as animal and vegetable oils) in cookers.
Combat principle
Water-based fire extinguishers, foam extinguisher, ammonium phosphate dry powder fire extinguishers and halon fire extinguishers can be selected for class A fire fighting.
Foam extinguisher (chemical foam extinguisher is limited to extinguishing nonpolar solvents), dry powder fire extinguishers, halon fire extinguishers and carbon dioxide fire extinguishers can be used for Class B fires.
Dry powder fire extinguishers, halon fire extinguishers and carbon dioxide fire extinguishers can be selected to put out Class C fires.
To put out Class D fires, powdered graphite fire extinguishers and special dry powder fire extinguishers can be used, or dry sand or cast iron chips can be used instead.
You can choose dry powder fire extinguishers to put out class F fires.
Dry powder fire extinguishers, halon fire extinguishers and carbon dioxide fire extinguishers can be selected to put out the fire on site. Electrified fires include fires of household appliances, electronic components and electrical equipment (computers, copiers, printers, fax machines, generators, motors, transformers, etc.). ) and the wires and cables are still charged when burning, and the fire in the ceiling, wall-hung daily lighting lamps and equipment that can automatically cut off the power supply after fire should not be included in the scope of charged fire.
O (_) O is expected.
Question 8: There is a fire in the pot at home. What is the best way to put out the fire? 1, directly cover the lid, the simplest way.
You can throw lettuce in it, which is sometimes useful.
Question 9: What should I do if there is a fire in residents' homes? This friend, fires in residents' homes often have the characteristics of fierce burning, rapid fire spread, rolling smoke and easy casualties. In addition, many urban residents use coal gas or liquefied petroleum gas, which is easy to form gas combustion and explosion after fire. At the same time, after the fire broke out in residents' homes, due to the lack of self-help ability, it often caused casualties and serious economic losses. If the family fire is not controlled in time, it will also affect neighbors and make the whole residential building or the whole village suffer from fire hazards. In order to reduce casualties and property losses, the fire department introduced the methods and measures to put out family fires.
1. No matter whether your family or neighbors are on fire, you should immediately call the police and actively put out the fire. Timely and accurate alarm can make the masses and fire brigade arrive quickly and put out the fire as soon as possible. According to the fire, you can also take the method of fighting and alarming. But don't forget that calling the police just to put out the fire or rescue items will delay the opportunity and turn a small fire that could have been put out in time into a big fire.
When someone is besieged, you should save people first. When saving people, we should focus on saving the elderly, children and those who are most threatened by fire. When there is a fire at home or the fire comes from outside, we should also organize family members to evacuate to a safe place in time according to the fire.
3. If a fire is found in a closed room, don't open the doors and windows casually to prevent fresh air from entering and expand the combustion. Check the fire from the outside first. If the fire is small, or there is only smoke and no light, you can use buckets, washbasins, etc. Prepare fire water and quickly enter the room to put out the fire.
4. After an indoor fire, if it is difficult to control the fire for a while, you should first grab flammable and explosive dangerous goods such as indoor liquefied gas tanks and gasoline.
5. In case of fire of household appliances and appliances, immediately cut off the power supply, and then use dry powder fire extinguishers, carbon dioxide fire extinguishers, 12 1 1 fire extinguishers, or use wet quilts and canvas to extinguish the fire. Fire extinguishing with water and foam must be carried out under the condition of power failure to prevent electric shock casualties caused by water conduction.
6. The kitchen is on fire, and the most common one is the oil pan. In case of fire, cover the oil pan with a pot cover immediately. Never put out the fire with water or lift the pot by hand to prevent hot oil from spilling out, scalding people and expanding the fire. If the oil fire is scattered on the stove or on the ground, you can put it out with a portable fire extinguisher or cover it with a warm quilt or blanket.
7. When the household liquefied petroleum gas storage tank is on fire, the key to extinguishing the fire is to cut off the gas source. If the flame at the valve port is large, you can beat the root of the flame with a wet towel or rag. Or grab a handful of dry powder fire extinguishing agent and sprinkle it on the flame to put out the fire and then close the valve. If the valve is overheated, the leakage can be blocked with wet towel, soap and yellow mud, and the liquefied gas tank can be quickly moved to an outdoor open place to discharge residual gas or be handed over to relevant departments for treatment. But at this time, monitoring must be done to prevent the existence of fire sources.
