Ask for a home fire safety report.

1 first of all, you should have a list in your mind to know all the possible exits of your room, such as doors, windows, skylights, balconies, etc. You should think that there are at least two exits in each bedroom, that is, except doors, windows can be used as emergency exits. If you know several escape routes, when the main passage is blocked, you can take other routes to survive.

Second, let family members, especially children, know about the structure of door locks and how to open windows. Let the children know that in an emergency, you can smash the window glass with a chair or other hard objects. In addition, doors and windows should be installed to be easy to open and close.

Third, you can draw a residential floor plan, mark all doors and windows with special signs, mark each escape route, mark the obstacles that may be encountered on each route, draw the external characteristics of the house, and mark the assembly place of family members after escape.

Fourth, let the family remember the following escape rules: First, close the bedroom door when sleeping to resist the invasion of heat waves and smoke. If you have to run from room to room to escape, you should close the door when you get to another room. The second is to touch the door before opening it. Never open the door if it is very hot or smoke comes out from the crack. You should prepare a second escape route. If the door is not hot, you can only open it slowly and quickly, and close the door behind you. Third, if the exit passage is infected by smoke, there is no other route to take, and you can crawl through the smoke area near the ground. Fourth, don't waste time getting dressed and taking valuables. Fifth, once you arrive at the family gathering place, you should count the number of people immediately. In the meantime, don't let anyone go back inside. It is best for professional firefighters to find and save people.

Five, to the residential floor plan and escape rules posted in a conspicuous place in the home, so that all family members can often see, at the same time, at least once every six months for family fire drills.

Common sense of family fire protection:

1. When there is a fire at home, don't panic, judge the fire source and take the opposite direction to escape. Do not use lifting equipment (elevator) to escape. Don't go back to the house to get valuables. When there is a fire at night, wake up the sleeping people first, don't just try to escape by yourself, shout as loudly as possible to remind others to escape.

2. How to use electricity safely in family houses? Reasonable installation of switchboard. 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. 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. Arrange the wires reasonably. 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. 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, if the capacitor is 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.

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. 3. How do you lay wires at home?

Answer: (1) The withstand voltage level of the conductor should be higher than the working voltage of the line, the safe current of the section should be higher than the load current and meet the requirements of mechanical strength, and the insulation layer should conform to the installation mode and environmental conditions of the line.

(2) The line should be far away from the heat source. If it must pass, it should be insulated so that the temperature around the conductor does not exceed 35℃.

(3) Metal devices used for line laying shall be treated with anticorrosion.

(4) All kinds of open wiring should be laid horizontally and vertically. When the conductor is laid horizontally, it is not less than 2.5m from the ground and not less than 1.8m when it is laid vertically, otherwise it needs to be protected to prevent mechanical damage.

(5) The wiring is easy to maintain, and the wires need to be insulated or isolated when crossing with wires and pipelines.

(6) The number of wire connectors should be reduced as much as possible. The conductor should not be subjected to mechanical action at the connection and branch, and the large-section conductor should be connected with the terminal of the same metal as the conductor.

(7) When the conductor is installed through the wall, the through-wall pipe should be adopted, and the two ends protrude from the wall surface not less than 10 mm ... The insulation resistance of the line to the ground should not be less than every volt 1000 ohm. 4. How to prevent wire insulation damage?

Answer: (1) The current passing through the conductor should not exceed the safe current carrying capacity of the conductor;

(2) Do not damp, heat, corrode, bruise or crush the wires. Try not to let the wires pass through places with high temperature, high humidity and corrosive steam and gas. When the wire passes through the place where it is easy to be bruised, it should be properly protected.

(3) Check the maintenance lines regularly, and repair them immediately if there are any defects. Old and aging wires must be replaced in time to ensure the safe operation of the lines. 5. How to prevent TV from causing fire?

Answer: (1) The TV should be placed in a place with good ventilation and heat dissipation.

(2) Don't turn off the TV with the remote control for a long time. After watching TV, cut off the power and unplug it.

(3) The viewing time should not be too long.

(4) Watch TV as little as possible in thunderstorm weather, and don't use outdoor antenna. 6. How did the family deal with the TV fire?

Answer: First, unplug the TV quickly, and then wrap the TV tightly with airtight objects such as quilts, so that the flame in the TV will go out because there is no air. However, it must be noted that when putting out a TV fire, the human body should avoid the front of the screen and stand on the back of the TV. It is forbidden to splash water directly on the fluorescent screen to prevent the cold explosion from suddenly damaging the imaging tube. 7. 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. 8. How to prevent refrigerator fire?

Answer: The main fire hazard of the refrigerator is that the refrigerator will produce sparks, such as the thermostat, protective relay, starting relay and lighting lamp will produce sparks when they are turned on or off. Therefore, when using the refrigerator, you should do the following:

(1) Don't put inflammable and explosive articles such as gasoline, alcohol and adhesive into the refrigerator to avoid explosion.

(2) The refrigerator can't be used in the environment with flammable gas, and flammable spray paint can't be used beside the refrigerator. If gas or liquefied petroleum gas leaks, never unplug the power plug, open and close the refrigerator door, and turn off the thermostat, otherwise an electric spark will occur and an explosion will occur.

(3) In the absorption refrigerator, always check the tightness of the system pipeline to avoid refrigerant leakage and cause combustion and explosion accidents. 9. How to prevent electrical protection from causing fire?

Answer: (1) The electric furnace should be placed in a fixed place and padded with incombustible materials;

(2) Flammable articles shall not be placed within the range of 1.5m around;

(3) The electric furnace should have a special socket or a separate line for power supply, and should not share a socket with other electrical appliances;

(4) When in use, people are not allowed to leave the site;

(5) Unplug the plug when power is cut off or not in use, and put it away after it is completely cooled. 10. How to prevent fire caused by electric iron?

Answer: (1) Don't blindly use high-power soldering iron, otherwise it may burn out the watt-hour meter or overheat the power cord and catch fire. If you are not skilled in ironing, it is easy to burn clothes and even catch fire.

(2) Make a safe iron bracket. When ironing clothes, the electric iron is picked up and put away, which is easy to cause misplaced mistakes. For the sake of safety, the electric iron bracket with legs can be made of incombustible heat insulation material, so that the electric iron is about 20 cm away from the desktop to avoid fire.

(3) Use with caution. You should know the temperature of the electric iron when ironing clothes. If it is overheated, unplug it in time. When you plug in the power supply and wait for the temperature to rise, don't do anything else, otherwise it's easy to forget and have an accident. Be sure to develop "when people leave, dial the plug;" Not yet. The iron is upright. Especially in the use of sudden power failure, you should also unplug the plug in time.

(4) Let it cool before collection. After use, the electric iron should be placed in a safe place away from flammable materials. When the temperature drops to a level that is not hot to the touch, the power cord can be easily wound around the handle and stored in a dry place.

1 1. How to prevent the fire caused by electric fans?

Answer: (1) Strictly control the use time of electric fans. If the electric fan runs continuously for half a day, it should be turned off and have a rest; If people leave home, they must turn off the electric fan; Especially when there is a sudden power failure during use, the electric fan should be turned off immediately to prevent another sudden call, which will cause the electric fan to run for a long time.

(2) When the electric fan is turned on every year, oil should be dripped into the oil hole of the motor to keep the rotating friction part lubricated to avoid high temperature; Usually, the motor is often wiped with a clean rag to remove the dust attached to the shell.

(3) The motor will not be affected with damp when in use; Do not use it where there are explosive and flammable materials. Choose a stable and firm position to exhaust the fan to prevent the fan blade and motor from being damaged by knocking.

(4) Three-core plugs must be used to ensure that the shell is well grounded to prevent electric shock accidents. Always check whether the electrical components are firmly connected to the power cord, and whether the power cord is aging or damaged. If problems are found, they should be repaired and replaced in time, and never "work with illness".

(5) When the electric fan is running, if there are abnormal conditions such as slow speed, burning smell, black smoke, and "numb hands" on the shell, you should immediately unplug the power plug and send it to the electrical maintenance department for inspection and maintenance. 12. How to prevent the air conditioner from catching fire?

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

(2) The air conditioner should have a protection device, and the fuse will cut off the power supply in case of failure;

(3) When using the air conditioner, it shall be operated in strict accordance with the requirements of the air conditioner, and the air conditioner shall not be modified to increase its use function;

(4) Sufficient margins should be reserved for the watt-hour meter and wires of the air conditioner, and appropriate power fuses should be selected to prevent overload;

(5) The air conditioner must have grounding or zero protection, and the insulation resistance should not be less than 2 megohms before it can be used. The sealing terminal of the fully enclosed compressor should be subjected to withstand voltage and insulation tests to prevent it from causing the refrigerant 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. 13. How to use the electric blanket safely?

(1) When you buy an electric blanket, you should check the quality. Be sure to buy products that have passed the inspection by the national quality inspection department, and pay attention to whether the rated voltage of the electric blanket is the same as that of the power supply used at home (the low-voltage safety electric blanket must be equipped with a corresponding step-down transformer and cannot be directly connected to 220 volts). Read the "Product Instruction Manual" carefully before use, and operate in strict accordance with the use requirements and precautions.

(2) Electric blankets with linear wires cannot be used in Simmons, sofa beds, spring beds and other beds with high elasticity; The spiral heating wire electric blanket has high tensile strength and good folding resistance, and can be used in various beds.

(3) Electric blankets must be laid flat under sheets or thin mattresses. Never fold it and use it. Because it is folded, it is easy to increase the thermal effect of the electric blanket, which leads to poor heat dissipation of the electric blanket, rising temperature, burning the insulation layer of the electric heating wire and causing combustion; Second, it is easy to break the heating wire and damage the electric blanket.

(4) When using the electric blanket, someone should be supervised nearby. When going out from home or losing power, be sure to unplug the power cord to avoid accidents caused by overheating of the electric blanket after long-term electrification.

(5) The temperature of most electric blankets will rise to about 38℃ after being electrified for 30 minutes. At this time, the temperature adjustment switch should be turned to low temperature, or the electric blanket should be turned off, otherwise the temperature will continue to rise, and long-term heating may cause the cotton cloth of the electric blanket to carbonize and catch fire.

(6) Electric blankets cannot be laid on objects with sharp protrusions, nor can they be directly laid on the gravel floor, let alone let children jump on the bed covered with electric blankets, so as not to damage the electric hotline.

(7) During the use and storage of the electric blanket, repeated folding and opening at a fixed position should be avoided, so as to prevent the electric heating wire from breaking due to folding fatigue, generating sparks and causing fire; In order to prevent the electric blanket from folding, the four corners of the electric blanket can be sewed with cloth belts, which can be tied to the four feet of the bed after being laid flat.

(8) Electric blankets that are wet or dirty by urine cannot be rubbed by hand, otherwise the insulation layer of the heating wire will be damaged or the heating wire will be broken. Dip a soft brush in a water brush and dry it before using it. It's better to cover the electric blanket with a layer of cloth, so it's much more convenient to clean when the cloth cover is dirty.

The average service life of electric blanket is about 5 years. If it is not hot or hot when used, the switch fails, the electric hotline is broken, and so on. It should be sent to manufacturers or appliance repair shops for repair, because ordinary families can't do heat preservation well. In order to prevent electric shock or fire accidents, ordinary users should not disassemble and repair at will. After maintenance, the electric blanket should be electrified and observed for 2 to 3 hours before use. 14. 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 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, the insulation 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. 15. 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 line is damaged and needs to be replaced, it can only be rerouted. When changing wires, there should be no connector in the middle, because the connector is directly buried in the wall. Over time, the insulation tape at the joint will age, and it will leak electricity if it is buried in the wall for a long time. 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. 16. 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. 17. 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. 18. Why should 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. 19. What are the most common dangers in the use of household appliances?

Long-term use, wire or motor overheating and damage insulation, resulting in wire short circuit and fire. 20. Where are the wires short-circuited most frequently? Contact parts of sockets and plugs, exposed wires are damaged by external force or electrical appliances are overheated, resulting in internal short circuit. Portable foam extinguisher suitable for fire and its use method

Scope of application: fire extinguisher principle

It is suitable for fighting general Class B fires, such as oil and grease fires, and also suitable for Class A fires, but it cannot fight water-soluble flammable and combustible liquids, such as alcohol, ester, ether, ketone and other substances in Class B fires; It is also impossible to put out live equipment and class C and D fires. Usage: You can carry the lifting ring on the top of the bucket and go to the fire quickly. At this time, care should be taken not to tilt the fire extinguisher excessively, nor to hold it horizontally or upside down, so as to avoid mixing the two chemicals and spraying it in advance. When the distance from the ignition point is about 10 meter, the cylinder can be turned upside down, with one hand holding the bail tightly and the other hand holding the cylinder bottom ring, aiming the jet at the combustion products. When putting out flammable liquid fire, if it is already flowing and burning, spray foam from far and near to make the foam completely cover the burning liquid surface; If burning in a container, the foam should be shot at the inner wall of the container, so that the foam can flow along the inner wall and gradually cover the fire surface. It is strictly forbidden to spray directly on the liquid surface, so as to avoid the burning liquid from being scattered or rushing out of the container due to the impact of the jet, and expand the combustion range. When putting out the fire of solid matter, the jet should be aimed at the place where the fire burns most violently. When putting out a fire, with the shortening of the effective spraying distance, users should gradually approach the burning area and always spray foam on the burning object until it is extinguished. When in use, the fire extinguisher should always be turned upside down, otherwise the spraying will be interrupted. Foam extinguisher should be stored in a dry, cool, ventilated and convenient place, not near high temperature or places that may be exposed to sunlight to prevent carbonic acid from decomposing and failing; Anti-freezing measures should be taken in winter to prevent freezing; And should always wipe the dust, dredge the nozzle, keep unobstructed.

Cart-type foam extinguisher suitable for fire and use method thereof

Scope of application: it is suitable for fighting general Class B fires, such as oil and grease fires, and can also be used for fighting Class A fires, but it cannot fight water-soluble flammable and combustible liquids, such as alcohols, esters, ethers, ketones and other substances in Class B fires; It is also impossible to put out live equipment and class C and D fires. dry-chemical fire extinguisher

Usage: When using, it is usually operated by two people. First push and pull the fire extinguisher to the fire point quickly, and stop at a place about 10 meters away from the fire point. After one person applies the spray hose, hold the spray gun tightly with both hands and aim at the burning place. The other is to turn the handwheel counterclockwise, so that the screw rises to the highest position, so that the bottle cap is completely opened, and then pour the steel bottle backwards, so that the pull rod touches the ground, rotate the valve handle 90 degrees, and spray foam to extinguish the fire. If the valve is installed at the spray gun, the person in charge of operating the spray gun will open the valve. The fire extinguishing methods and precautions are basically the same as those of portable chemical foam extinguisher, which can be used for reference. This kind of fire extinguisher can give full play to its advantages because of its long spraying distance and long continuous spraying time, and can be used to extinguish the initial fire of large-area storage tanks or tankers.

Air foam extinguisher is suitable for fire and its use.

Scope of application: basically the same as chemical foam extinguisher. However, solvent-resistant foam extinguisher can also extinguish the fire of water-soluble flammable liquids, such as the initial fire of burning solvents such as alcohol, ether and ketone. Usage: When in use, you can quickly rush to the fire site with your hands or shoulders. When it is about 6 meters away from the burning material, pull out the safety pin, and hold the opening handle in one hand and the spray gun in the other. Squeeze the opening handle hard, open the seal or puncture the seal of the gas cylinder, and the air foam can be ejected from the nozzle of the spray gun. The fire extinguishing method is the same as that of portable chemical foam extinguisher. However, when using the air foam extinguisher, the fire extinguisher should always be in an upright position, and it should not be used upside down or horizontally, otherwise the spraying will be interrupted. At the same time, always hold the open handle tightly, and don't let go, otherwise the injection will be interrupted.

Acid-base fire extinguisher suitable for fire and its use method

Scope of application: suitable for extinguishing the initial fire of class A substances, such as wood, fabric, paper and other fires. It cannot be used to put out fires caused by the burning of Class B substances, nor can it be used to put out fires caused by Class C combustible gases or Class D light metals. At the same time, it cannot be used to put out the fire of charged objects. Usage: When using, you should lift the ring on the upper part of the steel cylinder and rush to the fire site quickly. Never put the fire extinguisher on your back, and don't tilt it too much to prevent the two liquids from mixing and spraying in advance. When it is about 6 meters away from combustible materials, the fire extinguisher can be reversed and shaken several times to speed up the mixing of the two liquids; Hold the lifting ring with one hand and the bottom ring under the cylinder with the other hand, and aim the jet at the place where the combustion is the fiercest. At the same time, with the decrease of injection distance, users should push closer to the burning place. symbol

How to use a carbon dioxide fire extinguisher

When putting out a fire, you only need to lift or carry a fire extinguisher to the fire site. Put down the fire extinguisher and pull out the safety pin when it is about 5 meters away from the combustibles. Hold the handle at the root of the horn with one hand and the pressure handle of the switch valve with the other hand. For carbon dioxide fire extinguishers without water hose, the horn should be at 70-90 degrees with the upper plate. When using, you can't directly grasp the outer wall of the horn or the metal connecting pipe with your hands to prevent your hands from being frostbitten. When putting out fire, when combustible liquid burns in a flowing state, the user sprays the jet of carbon dioxide extinguishing agent from near and far to the flame. If combustible liquid burns in the container, the user should raise the horn. Spray into the combustion container from the upper part of one side of the container. However, the carbon dioxide jet can not directly impact the surface of combustible liquid, which prevents combustible liquid from being washed out of the container, expands the fire and brings difficulties to fire fighting. Cart-type carbon dioxide fire extinguishers are generally operated by two people. When in use, two people push or pull the fire extinguisher to the burning place together and stop at a distance of about 10 meter from the burning object. One person quickly takes off the horn, unfolds the spray hose, holds the handle at the root of the horn, and the other person quickly turns the handwheel counterclockwise to the maximum position. The fire extinguishing method is the same as the portable method. Principle: Let the temperature of combustible materials decrease rapidly and be isolated from the air. Advantages: when putting out a fire, it won't damage articles because it leaves any traces, and it can be used to put out books, documents, expensive equipment, precision instruments and so on. Note: When using the carbon dioxide fire extinguisher, if it is used outdoors, it should be sprayed in the upwind direction, and the hand should be placed on the wooden handle of the steel cylinder to prevent frostbite. If it is used in an outdoor narrow space, the operator should leave quickly after the fire is put out to prevent suffocation.

Portable dry powder fire extinguisher adapted to fire and its use method

Sodium bicarbonate dry powder fire extinguisher is suitable for the initial fire of flammable, combustible liquids, gases and charged equipment; Ammonium phosphate dry powder fire extinguisher can be used not only for the above kinds of fires, but also for the initial fire of solid substances. But they can't put out the fire of metal burning. When putting out a fire, you can quickly walk to the fire with a fire extinguisher in your hand or a fire extinguisher on your shoulder, and put down the fire extinguisher about 5 meters away from the burning place. If you are outdoors, you should choose to spray against the wind. If the dry powder fire extinguisher used is of external pressure storage type, the operator should hold the spray gun tightly with one hand and lift the opening bail on the gas cylinder with the other hand. If the cylinder is opened by handwheel, loosen it counterclockwise, turn it to the highest position, and then lift the fire extinguisher. When the dry powder is ejected, it is quickly aimed at the root of the flame. If the dry powder fire extinguisher used is built-in gas cylinder or pressure storage type, the operator should first unplug the safety pin on the opening handle, then hold the nozzle at the front end of the spray hose, and press the opening handle with the other hand to open the fire extinguisher to extinguish the fire. When using a fire extinguisher with a spray hose or an accumulator fire extinguisher, always hold down the handle with one hand and never let go, otherwise the spray will be interrupted. When using dry powder fire extinguisher to put out flammable and combustible liquid fires, the quasi-flame should be directed at the main parts. If the extinguished liquid fire is flowing and burning, the root of the quasi-flame should be shot from near to far, left and right, until all the flames are extinguished. If combustible liquid burns in the container, the user should shake the root of quasi-flame left and right to make the sprayed dry powder flow cover the whole opening surface of the container; When the flame is driven out of the container, the user should continue to spray until the flame is completely extinguished. When extinguishing the flammable liquid fire in the container, it is necessary to pay attention to the fact that the nozzle is not directly aimed at the liquid level to prevent the impact of the jet from splashing flammable liquid, which will expand the fire and bring difficulties to the fire extinguishing.
