(a) Household appliances. When a household appliance or a line is on fire, it is necessary to cut off the power supply first, and then use a dry powder or gas fire extinguisher to extinguish the fire. It is not possible to splash water directly to prevent electric shock or electrical explosion.
(1) Turn off immediately, unplug the power plug or pull down the main gate. If only the appliance is found to be igniting and smoking, the fire will self-extinguish after the power is turned off.
(2) If combustible materials such as wire insulators and electrical enclosures catch fire, they may be closed with ashes and other coverings to extinguish the fire.
(3) TV sets must not be fired to save TV fires, in case the TV's tubes are damaged. After you turn off the power,
Cover it with a quilt. When the fire is extinguished, the television must only be approached from the side to prevent the explosion of the picture tube. If fire extinguisher is used, it should not be shot directly
Touch the TV screen to avoid sudden explosion and explosion when it is heated.
(4) Household appliances may not be connected to the power supply after repair without fire, to avoid electric shock and fire accidents.
Note: Do not use water or foam extinguishing agents to extinguish the appliance fire without cutting off the power supply. Otherwise, the rescue personnel can
There is a danger of electric shock.
1, TV
There are many reasons for the fires on TVs, and there are many reasons for the use of electricity. There are also TV installation errors. Most of them are televisions
The machine is used for a long time, the ventilation is not good and the TV does not pull the power plug and so on. What happens when the TV set catches fire?
(1) Unplug the power plug first.
(2) Cover the TV with a thick quilt. Do not cover with a chemical fiber fabric. To prevent ignition.
(3) Use dry powder fire extinguisher and carbon dioxide extinguisher to extinguish fire.
(4) When extinguishing a fire, people should approach the television from the side of the television to prevent the kinescope from exploding.
(5) If the fire cannot be extinguished, report it immediately to the "119" fire.
2, computer
If the computer catches fire, even if the camera is turned off or even the plug is unplugged, the components inside the camera are still hot, and the flame will still enter and exit and produce toxic gas.
Screens and picture tubes may also explode. The methods to deal with them are as follows:
(1) When the computer begins to smoke or catch fire, immediately unplug the power plug or turn off the main power switch, and then cover the computer with a wet blanket or quilt, etc.
This will not only prevent the spread of fireworks but also block the glass fragments of the screen.
(2) Do not splash water on the fire-fighting computer, even if the computer has been turned off, because the sudden drop in temperature will burst the hot cathode-ray tube. In addition, there is still residual current in the computer, splashing water may cause electric shock.
(3) Do not open the cover to watch. When the fire is extinguished, the computer can only be approached from the side or behind to prevent the explosion of the tube.
3, tape recorder
The cause of the recorder's fire was that the power plug was not pulled out after listening to the recorder, and the power was not turned off.
(1) Ordinary tape recorders have no power switch, no power plug, and the tape recorder transformer is still working. When it smells long, it will become hot and the temperature will rise.
(2) The power supply voltage is unstable, especially when the power supply voltage exceeds 220 volts at night, causing the coil and iron core to generate heat.
(3) Transformer core, coil temperature is too high, after a period of time, the insulation was burned, causing the recorder to catch fire, igniting nearby combustibles and causing a fire.
(b) LPG. Use a soaked bedding, clothing, etc. to cover the fire and close the valve quickly. To extinguish the fire with a fire extinguisher or a soaked bedding, clothing, and tighten the gas tank angle valve switch, cut off the gas source, it is best to wear wet gloves or use wet hair to twist the angle valve. If the angle valve switch fails, you can use a damp cloth to plug the leak, and then take the gas tank to an empty place, so that the liquefied petroleum gas is drained. At this time, do not touch with the fire source to avoid fire. When the gas cylinder leaks and there is no fire, immediately open the doors and windows, let the air circulate, and lower the ambient temperature. Do not turn on the lights, use electrical equipment, or use open flames, otherwise explosions may occur.
(c) Oil pot fire. When the oil pan catches fire, the gas valve of the stove should be quickly closed, and the pan lid or wet rag can be directly covered, and the cut vegetables can be put into the pan to cool the fire. The smooth end of the pan can be separated from the fire and the pan can only be opened after cooling. Do not pour water into the oil pan.
(d) furniture, bedding, etc. catch fire. Fire extinguishing with water. Use watery objects such as a washbasin, etc. to splash water over the flame while cooling the combustibles near the burning point.
(5) The body clothes caught fire.
After a person gets on fire, he can't run, because the more he runs, the more prosperous he gets. This is because people will accelerate air convection and promote combustion when they run. The fire will become even fiercer. If you run, not only can you not extinguish the fire, but you can bring the fire to other places. It is also possible to increase the fire. This is very dangerous. should:
(1) When a few pieces of clothing are on the person's body, the fire does not burn the skin. The cloak of fire should be quickly taken off. Buttoned clothes can be used to grab the left and right clothes with both hands and can tear off the clothes. It is not possible to release the buttons one by one as usual, because time is too late. If you wear a zipper shirt, quickly pull the zip away and take off your clothes.
(2) If the person wears unlined clothes, he should quickly squat on the ground; when the clothes are on fire, they should lie on the ground; when the clothes are on fire before and after, they should roll back and forth on the ground, use the body to isolate the air, cover the flames, and suffocate the fire. But the speed of rolling on the ground cannot be fast, otherwise the fire is not easy to annihilate.
(3) At home, use a blanket, blanket, or sack to extinguish the fire. The effect is both good and timely. The flame will be extinguished as soon as it is opened and then covered on the body. The flame will immediately go out; if there is water right next to it, water can be used. Pouring.
(4) If rivers and ponds are nearby, they can quickly jump into shallow water. However, if the human body has been burned and the skin of the wound has been burned or the burn area is large, it is not appropriate to jump into the water to prevent infection.
(5) Never use a fire extinguisher to spray directly on the fire, as most fire extinguishers will cause infections in the burn wounds.
The stainless steel plate Water Tank adopts to the import food level SUS304,SUS316 stainless steel plate, blocking-up the sunlight irradiation thoroughly, does not multiply the algae, at any time maintains the water quality is clean.It can eradicate the second pollution completely. The stainless steel plate has light weight and high strength. The yield strength of stainless steel is equivalent to 1.5 times that of carbon steel and 6 times that of GRP. Compared with the SMC water tank, the Stainless Steel Water Tank has the better high temperature resistant performance. So it can apply to the request of fire and building standard act completely. Stainless Steel Water Tank adopts to the all welding assembly. Compared with the traditional water tank which connection by bolt, it get rid of the sealing strip and bolt to make the water tank more strength and never leakage.
