(4) For movable electrical appliances such as rice cookers, electric woks, and induction cookers, in addition to turning off the switch after use, the plug should also be unplugged to prevent the switch from malfunctioning. Because long-term power supply will damage electrical appliances and cause fire.

General households should not use electric stoves under normal circumstances. If they want to use electric stoves, they should have dedicated lines. Electric furnaces cannot be connected to household lighting circuits because the heating wire of the electric furnace may easily come into contact with the heater, causing direct or indirect electric shock accidents.

3. Will fluorescent lamps cause fire?

Although the tube temperature of fluorescent lamps is not high, fires caused by fluorescent lamps actually occur from time to time. Why is this? The problem is not with the tube, but with the ballast of the fluorescent lamp.

Fluorescent lamps of different specifications have different requirements for voltage and current, so they must be equipped with a ballast to reduce the voltage and limit the current. The ballast is composed of enameled coils and silicon steel sheets. . Its structure is like a small transformer, except that it has only one set of coils. When the ballast is energized, it consumes part of the electrical energy and converts the electrical energy into heat energy. Therefore, after the ballast is energized, both the coil and the silicon steel sheet will generate heat, especially those of poor quality. If the temperature is too high, the insulation will be damaged and a short circuit will be formed, which may ignite nearby combustibles.

Therefore, when purchasing, you should choose good quality. When installing, do not install the ballast directly on combustible materials, and pay attention to keeping a certain distance from combustible materials. You should also pay attention to it in daily life. Be moisture-proof and pay attention to ventilation. It is best not to turn on and off fluorescent lamps frequently.

The socket circuit should use single-strand insulated copper wire with a cross-section of not less than 2.5 square millimeters, and the lighting circuit should use a cross-section of not less than 1.5 square millimeters. single strand insulated copper wire. Generally, plastic sheathed wire can be used.

(5) During specific wiring, the plastic sheathed wires or other insulated wires used must not be directly buried in the cement or lime plaster layer. Because the wires are directly buried in the wall, they cannot be pulled out or pulled out. Once a certain section of line is damaged and needs to be replaced, the wall can only be cut open and rewired. When replacing the line, there cannot be a joint in the middle because the joint is directly buried in the wall. As time goes by, the insulating tape at the joint will age. , buried in the wall for a long time will cause leakage. In addition, the wiring in most homes will not be constructed according to the drawings, nor will accurate wiring drawing files be kept. When the wires in the wall of the home are damaged, or even nails are driven through the wires, causing phase and neutral short circuits, or the fuse may blow. , in severe cases, the electric spark generated during the short circuit may burn the person driving the nail, or even cause a fire. If the nails are only nailed to the phase wire, the nails are charged, and the person is standing on the ground, an electric shock accident is likely to occur. Therefore, it should be buried through pipes.

(6) The installation height of the socket is generally 1.3 meters from the ground, and the minimum should not be less than 0.15 meters. When wiring the socket, for a single-phase two-hole socket, the left side facing the socket is also connected to the working neutral line. The right hole is connected to the phase wire; for a single-phase three-hole socket, the left hole facing the socket is connected to the working neutral wire, the left hole is connected to the phase wire, and the upper hole is connected to the neutral line or ground wire. It is strictly prohibited to connect the upper hole and the left hole with wires.

(7) The installation height of wall switches is generally not less than 1.3 meters from the ground and 0.15-0.2 meters from the door frame. The wiring of the switch should be connected to the phase line of the lamp or electrical appliance being controlled.

(8) When installing a ceiling fan, the height of the fan blades from the ground should not be less than 2.5 meters. When installing a chandelier, when the weight of the chandelier is less than 1KG, soft wires can be used for self-lifting. However, the soft wires in the suspension box and lamp head must be knotted. When the weight of the chandelier exceeds 1KG, hanging chains, hooks, etc. should be used. The upper ends of the bolts It should be disconnected from the embedded parts of the building, and the wires should not be stressed.

According to regulations, it must be inspected every three years. Apply to local professionals with qualified certificates and use a "high resistance meter" for inspection.

15. What are the consequences of wire bundling?

Bundling of wires may cause parts of the wires to break, resulting in high impedance, causing the wires to heat up and cause wire fires.

16. Why should wires be prevented from being pressed down by heavy objects?

If the wire is pressed down by a heavy object, it may cause part of the wire to break, generate high impedance to heat the wire, and damage the insulation surface, resulting in a short circuit of the wire.

17. What are the most common dangers caused by the use of household appliances?

After long-term use, the wiring or motor will overheat and damage the insulation, causing a short circuit in the wire and causing a fire.

18. Where do wire short circuits occur most often?

At the contact parts of sockets and plugs, exposed wires are damaged by external forces or electrical appliances are overheated, causing internal short circuits.

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

If electrical plugs are not wiped regularly, dust, hair or patina will gradually accumulate on the poles of the plug, increasing the electrical impedance and causing fires.

20. What dangers will it cause if other metals are used instead of fuses?

The electricity is overloaded and cannot be fused, causing a fire.

21. What should be done if a transformer explodes or a wire falls to the ground?

Please notify the power company immediately and guard the scene to prevent pedestrians or vehicles from approaching (passing) to avoid the risk of electric shock.

23. How to put out a fire in a household appliance or wiring?

(1) Shut down the power immediately, unplug the power plug or pull down the main switch. If only the appliance is on fire and smoke, After the power is cut off, the fire will extinguish itself.

(2) If combustible materials such as wire insulators and electrical casings catch fire, they can be sealed with wet quilts and other coverings to suffocate the fire.

(3) Do not pour water directly to extinguish the fire to prevent electric shock or electrical explosion and injury.

(4) After a fire occurs, household appliances must not be connected to the power supply without being repaired to avoid electric shock and fire accidents.

(5) Do not use water or foam fire extinguishing agent to extinguish electrical fires without cutting off the power supply. Otherwise, firefighters may be in danger of electric shock at any time.

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

Electric shock is a type of electrical injury, that is, a certain amount of electric current passes through the human body, causing damage or dysfunction, or even death. Electric shock is very harmful to the human body. Most people who get electrocuted will have symptoms such as palpitation, panic, paleness, fatigue, and dizziness. People who are severely electrocuted may suffer convulsions, shock, and death. Electric shock may also cause complications, such as blindness, deafness, mental disorder, and paralysis. Moreover, the longer the electric shock lasts, the more harmful it is to life.

(1) When you encounter a partner who gets an electric shock, you should actively find ways to rescue them so that they can get out of danger as soon as possible and reduce the harm caused by the electric shock.

(2) To avoid electric shock, you must first understand the common sense of safe use of electricity. Generally, the installation of indoor wires is divided into two types: exposed installation and concealed installation. Electrical wires should be plastic sheathed wires that are moisture-proof, corrosion-resistant, and of suitable thickness.

Wrap black tape tightly around the outside of the wire connector. Do not hang clothes or items on electric wires. Do not tie the rope or wire used to dry clothes to the pole where the electric wires are installed or close to the electric wires.

(3) When you are at home alone, do not play with electrical appliances or pull out plug switches. If the switch is damaged, you can easily injure yourself by touching it.

(4) If you want to buy new electrical appliances at home, you must select them carefully, read the instructions carefully before use, and strictly follow the requirements.

(5) If a relative or partner gets an electric shock, the first thing you should do is cut off the power supply. If you can't find the power source for a while, you can use dry wooden sticks or bamboo poles to push away the wires. Never use metal or wet wood to touch the person being electrocuted, or directly touch the injured to avoid electric shock. If you can't find something suitable to pull the wire in a short period of time, or the injured person is already breathing weakly, then you have to find a way to cut or chop the wire to remove the electrocuted person from the power source.

(6) If the person who gets electrocuted happens to fall in a wet place, in this case, you must wear rubber shoes or stand on a dry wooden board to save the person. If the person who received an electric shock was exposed to high-voltage electricity of more than 1,000 volts, you must not approach the injured person because you are eager to save others. The powerful current will not let you go. You can only touch the electrocuted person if the power is turned off.

(9) If you find that the gas appliance in your home is faulty, you should find the manufacturer for repair in time and do not use it with the fault.

28. How to check whether the gas pipeline is leaking?

When you suspect there is a leak in the gas pipe (pipeline) in your home, do not use a match or lighter to test the gas. Instead, use soap bubbles to check for leaks.

29. Where is the safest place to install a gas water heater?

It should be installed outdoors in a well-ventilated area to avoid accidents of carbon monoxide poisoning.

30. What is the phenomenon of red flames in gas fireworks? What's the danger? How should this be handled?

The gas flame is normally light blue. If it is found to be red, it means incomplete combustion. There is a risk of carbon monoxide poisoning, so you should immediately ask a gas professional to check and adjust the stove.

31. How to know if there is a gas leak?

(1) Smell--Household gas is mixed with odorants, and there will be a self-odor when it leaks.

(2) Vision-gas leakage will cause mist-like white smoke to form in the air.

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

(4) Touch - when your hand is close to the leakage hole, you will feel a cool feeling.

32. How should residents take emergency measures after a flammable gas leak?

(1) When you smell a slight odor of combustible gas in your home, you must carefully identify and eliminate it. If you are sure that there is a slight leak in your home, you must first open the windows and doors immediately to create ventilation and convection and reduce the risk of gas leakage. Check the concentration of leaked combustible gas and close all doors and valves.

(2) While opening windows for ventilation, keep the original state of the electrical equipment in the leakage area, and avoid turning on and off electrical appliances to prevent an explosion, such as turning on lights (whether pull-string or button-type) , turn on the exhaust fan, turn on the range hood and make phone calls (whether it is a landline or a mobile phone), etc., to avoid generating sparks and arcs, igniting and detonating flammable gases.

(3) If the inspection finds that the leakage of flammable gas is not caused by obvious reasons such as the switch of the burner appliance being turned off or the hose being damaged, the property department must be notified immediately for inspection.

(4) If you smell a very strong combustible gas smell just after returning home, shout loudly and notify the neighbors as quickly as possible that "there is a combustible gas leak" so that everyone can pay attention to extinguishing it. Open flames and avoid switching electrical appliances. At the same time, leave the leak area, call 119 quickly in an area with low combustible gas concentration, and explain what kind of combustible gas leak is.

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

Once the gas tank catches fire, cover it with soaked bedding and clothing to extinguish the fire, and quickly close the valve.

44. What should you pay attention to when setting off fireworks?

Once fireworks and firecrackers are ignited by fire, some will rise into the sky and explode with sparks; some will emit flames several feet high, emitting colorful sparks. Fires can occur if fireworks are set off in an inappropriate location or method. (1) Do not set off firecrackers in public places, gas stations, etc. (2) Do not set off on balconies or indoors. (3) Fireworks and firecrackers should not be placed near fire, heat or power sources. (4) Children should set off fireworks and firecrackers under the supervision of adults. (5) Master the correct method of setting off, and inspect and clean the site after setting off to eliminate potential fire hazards. (6) Cannot be placed diagonally or horizontally.

(2) If the house has high-rise components, lightning protection devices should be installed;

(3) It is prohibited to use outdoor receiving antennas to watch TV programs during lightning and thunder.

46. Why does careless smoking cause fire?

The temperature of the cigarette butt tip is relatively high, with a surface temperature of 200 to 300 degrees Celsius and a core temperature of 7OO to 800 degrees Celsius. The ignition point of most combustible substances is lower than the surface temperature of the cigarette butt. For example, the ignition point of paper is 130°C, the ignition point of linen is 15°C, the ignition point of cloth is 200°C, the ignition point of candle is 19°C, the ignition point of linoleum is 165°C, and the ignition point of celluloid is 100°C. The ignition point of turpentine is 53 degrees Celsius, the ignition point of camphor is 7O degrees Celsius, the ignition point of rubber is 120 degrees Celsius, the ignition point of yellow phosphorus is 34 degrees Celsius, and the ignition point of wheat straw is 200 degrees Celsius. Therefore, once a cigarette butt is thrown on a combustible material whose ignition point is lower than the surface temperature of the cigarette butt tip, it is very easy to cause a fire accident.

47. What should you pay attention to when smoking?

(1) Smoking is strictly prohibited in no-fire areas.

(2) Smoking is prohibited when repairing cars and cleaning machine parts with oil.

(3) Do not smoke while lying in bed or on the sofa; bedridden elderly and patients who smoke should be cared for and advised not to smoke while in a coma.

(4) When smoking, if you have other matters temporarily, you should put out the cigarette butt before leaving.

(5) The scratched match stem and the remaining cigarette butts must be extinguished. Unextinguished match stems and cigarette butts should be put into ashtrays. Do not use paper rolls, matchboxes, etc. as ashtrays. Do not throw match stems and cigarette butts into wastebaskets or garbage chute, and do not litter them anywhere.

48. What should you pay attention to when lighting mosquito coils?

(1) Lighted mosquito coils should be placed on the ground away from curtains, mosquito nets, sheets, clothes and other combustible materials. If the lit mosquito-repellent incense is placed on a high object such as a window sill, it may blow and fall if blown by strong winds. If it falls on a combustible object, it may catch fire.

(2) When lighting mosquito-repellent incense, be sure to fix the mosquito-repellent incense on a special iron frame. Do not place the lit mosquito-repellent incense on combustible materials. Mosquito-repellent incense is made from pyrethrum and other medicinal plants, which are ground, blended and processed. It has a strong smoldering ability. Although there is no flame after being ignited, it can continue to burn. When mosquito coils burn, their temperature can reach about 700 degrees Celsius. This temperature greatly exceeds the ignition point of combustible materials such as wood, paper, cotton, linen, and chemical fiber fabrics. If a lit mosquito coil is placed on the above combustible materials, it will cause combustion.

(3) In the working place, if people want to leave, they must extinguish the mosquito coils to avoid leaving behind any trouble.

49. How to avoid fire after power outage?

(1) Use emergency lighting as much as possible;

(2) Cut off the power supply of electrical appliances in use promptly, that is, turn off the power switch or unplug the plug;

p>

(3) Use oil lamps with glass covers;

(4) It is strictly prohibited to use oil lamps to kill mosquitoes or place them in places where weeds are piled or on beds;

(5) Keep lighted candles away from mosquito nets, door curtains and other combustible objects; when using candles, place them in a place that is not easily touched, and have someone supervise them so that the fire is extinguished when people leave or sleep; candles should be placed in candlesticks or fixed on non-combustible objects such as porcelain plates, and shall not be placed on combustible objects such as TV cases or wooden furniture; do not use candles to search for things under the bed, in cupboards, or other small places.

(6) It is strictly forbidden to use gasoline instead of kerosene or diesel as fuel.

50. In what aspects do children need to pay attention to fire safety issues in their daily lives?

In daily life, the main thing is to train children to use and manage fire, electricity and gas correctly.

Fire refers to all open flames, such as furnace fires, lit candles, cigarette butts, etc. Parents or guardians should educate their children from an early age not to play with fire. Do not place matches, lighters, candles and other igniting objects within the reach of children. Children should not be left alone at home when adults go to work or go out on the street, and they should not be locked in the house. Children should be entrusted to the supervision of neighbors to avoid children Playing with fire at home can cause disaster. Thirdly, educate children not to set off firecrackers and fireworks indoors, near flammable materials, public entertainment venues, material warehouses, government schools and other places. They should also not set off firecrackers at residents' balconies and windows to avoid sparks flying and causing fires.

Electricity mainly refers to preventing electrical fires caused by children carelessly. On the one hand, educate children not to use home appliances such as stereos, computers, TVs, chargers, etc. when no one is at home, and not to disassemble or repair household appliances while the power is on. On the other hand, adults must not leave when using electrical appliances such as electric irons, hair dryers, electric stoves, electric blankets, and soldering irons to prevent children from touching these appliances out of curiosity and causing electric shock or fire accidents. Finally, educate children not to use light bulbs or heaters to bake clothes to avoid overheating and causing fires.

Gas mainly refers to the gas used in the home. What needs special reminder here is not to ask ignorant children to cook to avoid scalding the oil pan or causing fire caused by combustible materials roasted in the stove.

51. A good helper for extinguishing household fires--salt

When a small fire breaks out in a household kitchen, there are many ways to put it out. If possible, prepare a bag of dry powder or light fire extinguishing equipment in the kitchen, which can come in handy in case of fire. If you are not equipped with fire extinguishing equipment, you must use existing items in the kitchen to extinguish the fire. Table salt is a household fire extinguishing agent that can be chosen in an emergency.

Salt is widely used in daily life. It is not only an indispensable condiment, but also an effective fire extinguishing agent for fighting initial fires. The main component of table salt is sodium chloride (NaCl), which can be quickly decomposed into sodium hydroxide under high-temperature fire sources. Through chemical action, it absorbs free radicals in the combustion process and inhibits the progress of combustion. When the amount of salt used to extinguish a fire is sufficient, more free radicals are consumed than are decomposed by combustion, causing the combustion reaction to be interrupted. Keep some granular salt in your home, which is an effective extinguishing agent for kitchen fires and solid smoldering fires. Because of its large particles and high water content, granular salt absorbs heat and expands quickly at high temperatures, destroying the shape of the flame. At the same time, an endothermic reaction occurs, diluting the oxygen concentration in the combustion zone, so the fire is quickly extinguished. The fire-extinguishing properties of table salt can come in handy even in ordinary times. The fine salt surface has uniform particles and contains a certain amount of moisture, which is also a good helper for extinguishing oil fires.

52. How to formulate a home fire emergency plan?

(1) Have a list in your mind and understand all the possible escape exits in the room at home, such as doors, windows, skylights, balconies, etc. You should think of at least two exits for each bedroom, that is, in addition to Doors and windows can be used as emergency exits. If you know a few escape routes, you can take other routes to survive when the main passage is blocked.

(2) Always let family members, especially children, understand the structure of door locks and how to open windows. Let children know that in a pinch, they can smash the glass of a window with a chair or other hard object. In addition, doors and windows should be installed to be easily opened and closed.

(3) You can draw a floor plan of the house, mark all doors and windows with special signs, mark each escape route, indicate the obstacles that may be encountered on each route, and draw the external features of the house. Mark a spot for family members to gather after an escape.

(4) Let family members remember the following escape rules: First, close the bedroom door when sleeping to resist the intrusion of heat waves and thick smoke. If you have to run from one room to another to escape, close the door when you get to the other room. Second, touch the door before opening it. If the door is hot or smoke comes in through the crack, do not open the door and prepare a second escape route. If the door is not hot, you can only slowly open it a little and quickly pass through it, and then close it. Third, if the exit passage is blocked by dense smoke and there is no other route to take, you can stay close to the ground and crawl through the dense smoke area. Fourth, don’t waste time getting dressed and getting valuables. Fifth, once you arrive at the family gathering place, count the number of people immediately. At the same time, do not allow anyone to return to the house; search and rescue efforts are best left to professional firefighters.
