Fire safety knowledge (knowledge)

1. How to use electricity safely in residential buildings?

(1) Install the switchboard reasonably. Install the switchboard in a safe place outdoors. Don't pile firewood, clothes and other inflammable and explosive articles under the switchboard to prevent the hot molten beads from falling off the ignition articles after the fuse is blown. The choice of fuse should be based on the maximum household electricity consumption, and it is not allowed to replace the thick fuse or replace it with copper, iron wire or aluminum wire at will. Conditional families should install qualified air switches or leakage protection devices, which can act in time to cut off the current in case of electric overload or electric shock.

(2) Use the power cord correctly. The main line of household power cord shall be at least 4mm2 copper core wire, aluminum skin wire or plastic sheath line. In dry rooms, ordinary insulated wires can be used; in wet rooms, insulated wires with protective layers should be used; and electrical equipment that moves frequently should use flexible wires with good quality. The seriously aged wires should be replaced in time.

(3) Reasonable wiring. Reasonable and standardized wiring is beautiful and safe, which can effectively prevent short circuit. If the wires are exposed, in order to prevent the insulation layer from being damaged, you can choose better quality wires or wear flame-retardant PVC plastic pipes for protection; When passing through the surface of combustible decorations, light flame retardant sleeves should be worn, and the wires in the ceiling of rooms with ceilings should be protected by metal pipes or flame retardant PVC plastic pipes. For the wires that need to go through the wall, in order to prevent the insulation layer from being damaged, a hard plastic pipe should be built in the wall, and the outlets at both ends extend out of the wall by about 1 cm.

(4) Use household appliances correctly. First of all, be sure to read the instructions carefully and pay attention to its precautions and maintenance requirements. General air conditioners, microwave ovens, electric water heaters, ovens and other household appliances should not be switched on and off frequently. After use, not only turn it off, but also unplug it. If possible, it is best to install a separate air switch. For some household appliances with insufficient capacitor withstand voltage, the capacitor will be burned due to heat or moisture. If the temperature is abnormal, the power supply should be cut off for inspection and troubleshooting, and a voltage regulator should be installed on the line.

(5) Do a good job in fire prevention and extinguishing. When people leave home or sleep, check whether the electrical appliances are cut off. It is very necessary for families with conditions to buy a small fire extinguisher of more than 2 kg. At home, they should also prepare necessary escape tools, such as flashlights, ropes and towels. In case of electrical fire, don't panic. First, cut off the power supply in time and shout for help to the neighbors. Call the fire alarm number 1 19. At the same time, use the water, wet quilt or fire extinguisher prepared at ordinary times to extinguish the fire quickly. If the fire is too big, avoid danger in time, don't be greedy for money, and don't be reluctant to part with furniture and property. Life is the most important thing, and running for your life is important.

2. What should I pay attention to when using electricity in the kitchen?

(1) Wet hands are not allowed to touch electrical appliances and devices, otherwise it is easy to get an electric shock. It is best to use a cable switch for the light switch.

(2) The power fuse cannot be replaced by copper wire. Because copper wire has a high melting point, it is not easy to fuse and cannot protect the circuit, so it is necessary to choose a suitable fuse.

(3) Screw lampholders should be used and safety covers should be installed.

(4) Removable appliances such as rice cookers, electric woks and induction cookers should be unplugged after use to prevent switch failure. Because long-term electrification will damage electrical appliances and cause fire.

In general, ordinary families should not use electric stoves. If they want to use the electric stove, they should have a special line. The household lighting circuit cannot be connected to the electric furnace, because the electric heating wire of the electric furnace is easy to contact with the heater, which directly or indirectly causes an electric shock accident.

3. Will fluorescent lamps cause fire?

Although the temperature of fluorescent tubes is not high, in fact, fires caused by fluorescent tubes also occur from time to time. Why? The problem is not the lamp tube, but the ballast of fluorescent lamp.

Different specifications of fluorescent lamps have different requirements for voltage and current, so a ballast should be equipped to reduce voltage and limit current. Ballast is composed of enameled coil and silicon steel sheet. Its structure is like a small transformer, except that it has only one set of coils. When the ballast is energized, a part of electric energy is consumed and converted into heat energy. Therefore, after the ballast is energized, both the coil and the silicon steel sheet will heat up, especially the poor quality ones are more likely to heat up. If the temperature is too high, it will damage the insulation, form a short circuit and ignite the nearby combustible materials.

Therefore, the ballast with good quality should be selected when purchasing, and the ballast should not be directly installed on flammable materials when installing, and attention should be paid to keeping a certain distance from flammable materials. Attention should also be paid to moisture-proof ventilation in daily life, and it is best not to switch fluorescent lamps frequently.

How to prevent the microwave oven from catching fire?

(1) Avoid using closed containers: use wide-mouth containers when heating liquids, because the heat generated by food heating in closed containers is not easy to dissipate, so that the pressure in the containers is too high and it is easy to cause blasting accidents. Even if you cook food with shells, you should pierce the shells with needles or chopsticks in advance to avoid bursting after heating, splashing out to pollute the furnace wall or hurting people.

(2) Avoid fried food: high-temperature oil will splash and cause fire. In case of accidental fire in the furnace, don't open the door, turn off the power first, and then open the door to cool down after the fire is extinguished.

(3) Avoid working in front of the microwave oven for a long time: After turning on the microwave oven, people should stay away from the microwave oven or at least 1 m away from the microwave oven.

(4) Eggs with shells and sealed food cannot be cooked directly. In case of explosion.

(5) The furnace should always be kept clean. After disconnecting the power supply, wipe it with a damp cloth and neutral detergent. Do not rinse or let water flow into the electric appliances in the furnace.

5. How to prevent the electric mattress from catching fire?

(1) See if the voltage used is the same as the household power supply.

(2) Don't wet the electric mattress, otherwise it will easily cause leakage.

(3) Avoid breaking the heating wire to prevent short circuit.

(4) The power-on time should not be too long.

(5) Ordinary electric mattresses should not be used with other heat sources such as thermos bottles to avoid local overheating.

(6) Unplug the electric mattress after use.

6. How to prevent the electric fan from catching fire?

(1) The continuous working time should not be too long, and it should be used at intervals as far as possible. When you stop using it, you must unplug the power plug.

(2) Don't let water or metal objects enter the electric fan to prevent short circuit and fire.

(3) Add engine oil or sewing machine oil to the oil hole regularly to keep lubrication and avoid motor heating. Remove the dust from the shell and cut off the power supply.

(4) If it is found that the power consumption is high or the shell temperature rises, it should be repaired in time.

(5) If there is abnormal noise, smoke, burning smell and shell numbness, power-off measures should be taken quickly.

7. How to prevent the air conditioner from catching fire?

(1) Before starting the air conditioner, check whether there are any foreign bodies such as loose screws and fan displacement, and remove them in time to prevent accidents.

(2) The air conditioner shall be equipped with protective devices (such as thermal fuses, etc.). ). When a fault occurs, the fuse will be disconnected, cutting off the power supply.

(3) When using the air conditioner, it should be operated in strict accordance with the requirements of the air conditioner.

(4) Sufficient allowance should be left for the watt-hour meter and wires of the air conditioner, and appropriate power fuse should be selected. Once overloaded, you can cut off the power supply in time.

(5) The air conditioner must be well grounded or zero-connected, and the insulation resistance should not be less than 2m Ω before use. The sealing terminal of fully enclosed compressor should be tested for withstand voltage and insulation to prevent it from causing cold oil to overflow and catch fire.

(6) Flammable articles shall not be piled up around the air conditioner, and curtains shall not be hung on the window air conditioner.

(7) The air conditioner should be operated under the close supervision of the owner, and the switch should be turned off when people leave. Even the air conditioner with remote control device should not be left unused for a long time.

8. How to prevent the electric iron from catching fire?

(1) When using the electric iron, we must overcome careless thoughts, and we must not leave the electric iron in disorder, and the personnel shall not leave after the electric iron is electrified.

(2) Electric irons should not be collected in a hurry until they are completely cooled. Even if there is a power failure, all power supplies must be cut off (because once a phone comes in, it may cause a fire).

(3) The backing plate on which the electric iron is placed should not only have a considerable thickness (using incombustible materials), but also be far away from all combustible materials, because experiments have proved that the back temperature of 4cm red brick can reach 420℃ after heating 14O minutes; After heating 0.8cm steel plate and 1.5cm asbestos plate for 90 minutes and 68 minutes respectively, the back temperature can reach 280 degrees Celsius, which has reached the ignition point of ordinary fabrics.

(4) Install the connection according to the instructions, and the power supply voltage should meet the requirements. The power cord and lead-out wire of the electric iron should have sufficient cross section to prevent overload.

9. How to prevent TV from catching fire?

(1) The TV should be placed in a well-ventilated place, not in a cupboard or kitchen. If you want to put it in a cupboard or kitchen, you should open more holes in the cupboard and kitchen (especially the corresponding parts of the TV cooling holes) to facilitate air cooling.

(2) Don't put the TV set near the stove or heating pipe. Continuous viewing time should not be too long. Generally, it should be closed for a period of time after 4-5 hours of continuous viewing, especially in high temperature season.

(3) The power supply voltage should be normal. After watching TV, turn off the power.

(4) The TV set should be placed in a dry place. Pay attention to moistureproof in rainy season. If the TV is not used for a long time, it will be used for several hours at intervals. When using the TV, liquid should be prevented from entering the TV.

(5) Outdoor antenna or * * * antenna should have lightning protection facilities. Lightning arresters should be grounded properly, and outdoor antennas should not be used in rainy days.

(6) If the TV smokes or smells burnt, please turn off the TV immediately. If the TV is on fire, unplug it first, cut off the power supply, and put out the fire with a dry powder fire extinguisher. In the absence of a fire extinguisher, cover the TV with a quilt and cotton blanket to isolate the air and suffocate the fire. Don't splash it with water, because the TV set is hot at this time, and the picture tube will explode when it suddenly cools down.

10, how to prevent refrigerator fire?

(1) Don't store dangerous chemicals in the refrigerator; If it must be stored, pay attention to the absolute seal of the container to prevent it from leaking.

(2) Ensure that the back of the refrigerator is dry and ventilated, and do not place flammable materials behind the refrigerator; Do not let the power cord of the refrigerator touch the compressor and condenser.

(3) When the electric control equipment of the refrigerator fails, it should be stopped immediately for inspection and maintenance. It is necessary to prevent the temperature-controlled electrical switch from getting wet.

(4) After the refrigerator is cut off, it will take at least 5 minutes to restart.

1 1. How to prevent the washing machine from catching fire?

(1) Connect the wires before using the washing machine to prevent electric leakage and electric shock.

(2) Before putting away the clothes, check whether there are keys, knives, coins and other items in the clothes pocket. Don't put these hard things into the washing machine.

(3) Do not exceed the rated capacity of the washing machine at a time, otherwise the motor may be damaged due to overload.

(4) It is forbidden to put clothes that have been rubbed with flammable liquids such as gasoline into the washing machine immediately for washing. You can't pour gasoline into the washing machine to remove oil stains.

(5) Always check whether the insulation layer of the power cord is in good condition. If it is worn, aged or cracked, it should be replaced in time. Always check whether the washing machine leaks water. If it leaks, stop using it and repair it as soon as possible. The washing machine should be placed in a relatively dry and ventilated place.

(6) After the power supply is connected, if the motor does not turn, it should be powered off immediately, and then used after troubleshooting. If the contact between timer and selector switch is poor, it should be stopped.

12. What should I pay attention to when using electrical appliances in summer?

(1) For TV sets, air conditioners and other electrical appliances, the use time in summer should not be too long, generally not more than 10 hour, especially for TV sets, it is best to stop using them after watching them for four or five hours, and take cooling measures; For electric water heaters, always check whether the automatic regulating device is damaged to avoid explosion or fire caused by overheating; The refrigerator should also be placed in a ventilated place.

(2) Never put electric lights in the wardrobe to bake clothes.

(3) For electrical appliances that are often used in summer, such as electric showers, table fans, washing machines, etc. Some practical measures should be taken to prevent electric shock, such as often testing whether the metal shell is charged with an electric pen and installing an electric shock protector (leakage switch).

(4) There is more rain in summer, and more water is used. If water enters the house unexpectedly, the power supply should be cut off first, that is, the main switch or fuse in the house should be unplugged to prevent the household appliances being used from accidents due to water entry and insulation damage. Secondly, after cutting off the power supply, move the household appliances that may be wetted to a place that is not wetted, so as to prevent the insulation from being wetted, which will affect future use. If the electrical equipment has been soaked in water, the insulation is likely to be wet. Before using it again, test the insulation resistance with a special shaking table for equipment insulation. If it meets the specified requirements, it can be used, otherwise it should be dried until the insulation is good.

(5) Frequent use of household appliances in summer may lead to fuse blowing, which is a warning of excessive power consumption. Don't change the fuse thicker and thicker, lest it can't be blown in time when it is short-circuited, causing the wire to catch fire.

(6) Unplug idle or used electrical appliances.

13. What should I pay attention to in electrical decoration?

Electrical decoration, such as indoor circuit wiring, switch socket layout, chandelier, ceiling fan installation, etc. , it is necessary to be convenient, beautiful and save materials, but also to consider the whole decoration from the perspective of safety to avoid hidden dangers of accidents.

(1) You should ask an electrician who has passed the examination and has an electrician certificate to carry out electrical decoration for you.

(2) The electrical materials used must be qualified products, such as wires, switches, sockets, leakage switches, lamps, etc.

(3) In the incoming line of the house, a distribution box with a leakage switch must be installed. Because there is a leakage switch, once there is leakage at home, such as electric shell charging, personal electric shock and so on. The leakage switch will trip, thus ensuring personal safety.

(4) When wiring indoors, the socket circuit and the lighting circuit should be wired separately. The socket loop shall adopt a single-stranded insulated copper wire with a cross section of not less than 2.5 mm2, and the lighting loop shall adopt a single-stranded insulated copper wire with a cross section of not less than 1.5 mm2. Generally, plastic sheath line can be used.

(5) When wiring, the plastic sheath line or other insulated wires used shall not be directly buried in the cement or lime paint layer. Because the wires buried directly in the wall can't be pulled out and can't be pulled out. Once a section of the line is damaged and needs to be replaced, it can only be re-wired, but there can be no connector in the middle when changing the line, because the connector is directly buried in the wall. With the passage of time, the insulating tape at the joint will age, and long-term burial in the wall will cause leakage. In addition, the wiring of most families will not be constructed according to the drawings, and accurate wiring diagrams will not be kept. When the wire on the wall of the house is damaged, or even a nail pierces the wire, the phase wire and the zero wire will be short-circuited and the fuse will be blown under the light. In heavy cases, sparks generated during short circuit will burn nails and even cause fire. If the nail is only nailed on the phase line, the nail is charged and people stand on the ground, it is very likely to get an electric shock accident. So we have to bury it through pipes.

(6) The installation height of the socket is generally 1.3m from the ground, and the minimum should not be less than 0. 15m. When connecting the socket, the left side facing the socket should also be connected to the working zero line, and the right hole should be connected to the phase line; For single-phase three hole socket, the left hole facing the socket is connected to the working zero line, the left hole is connected to the phase line, and the upper hole is connected to the zero line trunk line or ground line. It is forbidden to connect the upper hole and the left hole with wires.

(7) The installation height of the wall switch is generally not less than 1.3m from the ground and not less than 0. 15-0.2m from the door frame. The wiring of the switch shall be connected to the phase line of the controlled lamps or appliances.

(8) When the ceiling fan is installed, the height of the fan blade from the ground shall not be less than 2.5m When installing the chandelier, when the weight of the lamp is below 1KG, the flexible wire can be used for self-hoisting, but the flexible wire in the hanging box and lamp holder must be knotted. When the weight of lamps and lanterns exceeds 1KG, chains and hooks should be used, the upper ends of bolts should be separated from the embedded parts of buildings, and wires should not be stressed.

14. How often do you check the wires in the house? Who do you want to check? How to check?

According to the regulations, the inspection should be conducted once every three years, and an application should be made to a local professional with a qualified certificate, and a "high resistance meter" should be used for inspection.

15, what are the consequences of wire binding?

The wire is bound, which may cause the wire to be partially broken, resulting in high impedance, heating of the wire, and then the wire will catch fire.

16. Why should the wires avoid being pressed by heavy objects?

If the wire is pressed by a heavy object, it may cause local fracture of the wire, resulting in high impedance and heating of the wire, damage to the insulation surface and short circuit of the wire.

17, what are the most common hazards in the use of household appliances?

Long-term use, wire or motor overheating and damage insulation, resulting in wire short circuit and fire.

18, where is the most common location of wire short circuit?

Contact parts of sockets and plugs, exposed wires are damaged by external force or electrical appliances are overheated, resulting in internal short circuit.

19. Why do electrical plugs need to be cleaned frequently?

If the electrical plug is not cleaned frequently, dust, hair or rust will gradually accumulate at the two poles of the plug, which will increase the electrical impedance and cause a fire.

20. What is the danger of replacing fuses with other metals?

The electricity consumption is overloaded, and it can't melt and cause a fire.

2 1. What if the transformer explodes or the wire falls to the ground?

Please inform the power company immediately, and guard the site on behalf of it, and don't let pedestrians or vehicles approach (pass) to avoid electric shock.

22. How to deal with the phenomenon that the meter shell or water pipe is a little leaking by hand?

Please immediately notify the power company (or district business office) or entrust the electrical equipment contractor to send someone to deal with it as soon as possible.

23. How to put out the fire of household appliances or lines?

(1) Turn off the power immediately, unplug the power plug or pull down the master brake. If only electrical appliances are found to be on fire and smoke, the fire will automatically go out after the power failure.

(2) If combustible materials such as wire insulators and electrical enclosures catch fire, wet quilts and other covers can be used to put them out.

(3) Don't splash water directly to put out the fire, so as to avoid electric shock or electric explosion.

(4) household appliances shall not be connected to the power supply without repair after a fire, so as to avoid electric shock and fire accidents.

(5) Don't put out the electrical fire with water or foam extinguishing agent without cutting off the power supply, otherwise the firemen are in danger of getting an electric shock at any time.

24. What should I do if I get an electric shock?

Electric shock is a kind of electric injury, that is, a certain amount of current passes through the human body, causing physical injury or dysfunction, and even death. The harm of electric shock to human body is quite great. Most people who get an electric shock will have symptoms such as palpitation, panic, pallor, fatigue and dizziness. Severe electric shock will also cause convulsions, shock and death. Electric shock may also cause complications, such as blindness, deafness, mental disorder and paralysis. And the longer the electric shock time, the greater the harm to life.

(1) When your partner gets an electric shock, you should actively try to rescue him, so that he can get out of danger as soon as possible and reduce the harm caused by electric shock.

(2) To avoid electric shock, first of all, you need to know the common sense of safe electricity use. The installation of indoor wires is generally divided into concealed installation and concealed installation. The wires shall be made of moisture-proof, corrosion-resistant and finely assembled plastic sheath line. Black tape should be wrapped around the wire connector. Clothes and articles shall not be hung on the wire, and the rope or wire for drying clothes shall not be tied to the post or near the wire.

(3) When a person is at home, don't play with electrical appliances casually and don't pull the latch switch. If the switch is broken, your touch can easily make you get an electric shock.

(4) When buying new appliances at home, you should carefully select them, read the instructions carefully before using them, and do them in strict accordance with the requirements.

(5) If a relative or partner comes into contact with electricity, the first thing you should do is to cut off the power supply. If you can't find the power supply at the moment, you can unplug the wire with a dry wooden stick or bamboo pole. Never touch the victim or the injured directly with metal or wet wood to avoid electric shock. If you can't find something suitable to dial the wire in a short time, or if the injured person is already breathing weakly, then you should try to cut and cut off the wire to get the electric shock person out of the power supply.

(6) If the electric shock happens to fall in a wet place, in this case, you must wear rubber shoes or stand on a dry board to save people. If the person who gets an electric shock is exposed to high voltage above 1000 volts, then you must not approach the injured person rashly because you are eager to save people, and the powerful current will not let you go. Only by turning off the power can you touch the person who gets an electric shock.

Gas safety

(3) Hearing-there will be a "hissing" sound.

(4) Touch-When the hand approaches the leak, it will feel cool.

32. How do residents take emergency measures after combustible gas leaks?

(1) When you smell a slight smell of combustible gas in your home, carefully identify and eliminate it. If it is determined that there is a slight leak in the home, first of all, open the door immediately to form ventilation convection, reduce the concentration of leaked combustible gas, and close all doors and valves.

(2) While opening the window for ventilation, keep the electrical equipment in the leakage area in its original state, and avoid switching the electrical equipment to prevent explosion, such as turning on the light (whether it is a cable or a button), turning on the exhaust fan, turning on the range hood, and making a phone call (whether it is a landline or a mobile phone), so as to avoid sparks and arcs, and igniting and detonating combustible gas.

(3) If it is found that the combustible gas leakage is not caused by obvious reasons such as the burner switch is not turned off or the hose is damaged, it shall immediately notify the property department for maintenance.

(4) If you smell a strong smell of combustible gas as soon as you get home, you should shout it out quickly and inform your neighbors that "combustible gas has leaked" in the fastest way, so that everyone can pay attention to putting out open flames and avoid switching on and off electrical appliances. At the same time, if you want to leave the leakage area, call 1 19 where the concentration of combustible gas is low to explain what kind of combustible gas is leaking.

33. What should I do if the gas tank catches fire?

Once the gas tank catches fire, cover it with soaked bedding and clothes to put out the fire, and quickly close the valve.

34. Will poison gas kill people?

(1) gas itself is not toxic, but it has anesthetic and asphyxiating effects, which reduces the biological reaction ability.

(2) Improper use of gas will produce a large amount of carbon monoxide, which is easy to combine with heme in blood, resulting in death due to lack of oxygen.

35. What about carbon monoxide poisoning?

(1) Turn off the gas switch.

(2) Open the doors and windows for ventilation.

(3) Provide fresh air for the injured.

(4) untie the bondage and dredge the respiratory tract.

(5) Artificial respiration or cardiopulmonary abdominal pressure is performed when necessary.

(6) Do not turn on or off any power switch before the smell of gas dissipates, so as to avoid sparks and fire.

36. What should I do if I accidentally cut off the gas pipeline during construction?

If the gas pipeline is accidentally cut off due to sewage pipeline construction, please turn off the fire source at home immediately. If the pipeline is on fire, don't put out the fire hastily, draw a warning line and call the police as soon as possible. Residents or passers-by near the pipeline cut-off should avoid smoking, or start the steam engine, motorcycle engine and various power switches to avoid explosion or combustion. Personnel should stay away from the scene as far as possible. Before the handlers arrive at the scene, please enclose the scene with ropes and write slogans such as gas leakage to remind people and vehicles passing by.

fire safety

37. What should I do if the oil pan catches 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 the pot 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.

38. How to prevent fire in winter heating?

Attention should be paid to heating with fire: the chimney of the stove should be far away from wires, flammable ceilings, wooden walls, wooden doors and windows and other flammable and combustible objects; There should be a grate made of incombustible materials around the furnace body; Don't put waste paper, shavings and other flammable materials around the fire; When cleaning furnace ash and slag, don't pour them into combustible materials. It is best to have a fixed safe place, and pay more attention to strengthening fire prevention when dumping furnace ash in windy days. When baking clothes and bedding, pay attention to baking items to prevent fire caused by too long baking time; Never use gasoline, diesel oil, alcohol, etc. When making a fire, so as not to cause a fire.

Attention should be paid to the use of electric blankets for heating: First, buy electric blankets from regular manufacturers. When buying, be sure to ensure good quality; Second, when in use, the electric blanket should be placed flat under the bed sheet or thin mattress, and must not be folded for use. The temperature of most electric blankets will rise to about 38℃ after being electrified for 30 minutes. At this point, the thermostat should be set to low temperature or turn off the power. Third, you can't use electric blankets on objects with sharp protrusions; Wet or dirty electric blanket should not be rubbed by hand, otherwise it will damage the insulation layer of electric heating wire or break it. It should be washed with a soft brush dipped in water and dried before use.

39, how to take effective measures to put out the fire at the beginning of the fire?

In addition to calling the "1 19" fire alarm number and explaining the route and house number, send someone to wait for the fire truck at the intersection. The following fire extinguishing methods can be adopted at home: First, use local materials to extinguish the fire, cover the fire with blankets and quilts, and then put it out. You can also use pots, barrels and other water to put out the fire in time, or use fire-fighting equipment in the floor to put out the fire in time. Second, individual items are on fire, so it is necessary to move the lit items outdoors to put out the fire. Third, when household appliances catch fire, cut off the power supply first, and then cover them with blankets and quilts to put out the fire. If they are still not extinguished, water them again. Fourth, gas and liquefied gas stoves are on fire. First, close the valves and cover them with aprons, clothes, quilts, etc. And then douse them. Fifth, timely evacuate combustible materials and liquefied gas tanks near the fire site to a safe place.
