【 Weak current College 】 public fire cause and prevention of---Power By 【 China power house network 】

Public fire most are people, the main reason for this is:
1. because of electrical equipment and power consumption is short, for temporary power supply in existing lines access power electric equipment so that it runs long overload, destroyed the line insulation, fire.
2. the lack of line of electrical maintenance and repair, leading to a year long use of line insulation damage after leakage, short circuit, causing a fire.
3. the fire is copper-aluminum wire connection, contact bad or use long, causing excessive contact resistance. Play sparks or junction temperature is too high.
4. use of mobile lighting Plug and socket contact bad fever; lighting position and the distance is too close to combustibles, also due to overheating and Khao ignited the fire.
5. the use of ironing clothes iron, hair dryer, dressing hair of welding equipment of electric instruments, such as iron, cut off the power, after forgetting to set aside in the combustible base; or after use, waste heat is not bulk, immediately mount combustible package, because the temperature is too high and cause a fire.
6. public places people use electric Cup, electric cooker, electric plates, electric equipment, long-term power, or forget to turn off the power switch is also easy to cause fires.
7. public places smoking people with places Italy, throw cigarette butts or match rod is also the main cause of the fire.
8. the fire is cinema, Club performances, in order to enhance the performance results, the use of firecrackers, Fireworks, flammable or explosive substances.
9. the fire so that the maintenance of public spaces, the illegal use of electricity, gas, not take security measures to spark on the fuel.
10. some site outage, some people will use the candle lighting, ignoring safety, ignite combustibles or use such as the curtain open fires to find things, etc.
In order to be effective in preventing a fire accident in public places, in addition to common sense for people to enhance fire safety education, you must take the following security measures:
① use electric equipment in public places, to keep away from combustible materials. Such as use of infra-red heaters, etc., because it has a high surface temperature, if near flammable substances, it is easy to start a fire.
② the use of lighting to maintain a certain combustible substances and the safe distance. Otherwise, the lighting to close in the wood or other combustible materials, the danger is great too. Because the surface temperature of the lamp is very high. For example, 60W incandescent, surface temperature up to 135-180 ℃; 100W incandescent, surface temperature can be as high as 170-220 ° c, so when the light bulb and combustible contact over time, will lead to a fire.
③ people use electric irons ironing clothing, or use hair dryer, dressing hair, after use, cut off the power supply should be timely, and placed on the base of noncombustible, light heat dissipated before storage. Do not use after the immediate load cartons, as remaining heat will lead to other flammable items, and fire.
④ in public places people repair electrical equipment using electric iron, after use, you should first remove the power plug and then placed in the non-combustibility of base or on the cement floor, never on the floor and desk to prevent overheating, floor and desk and fuel of fire.
⑤ live in the hotel and hotel guests as much as possible do not use point hot cup and electric appliances such as electric plates. As is required by the body, they may first ask the service personnel, with the consent of the parties to use, and care. Power plate of continuous use time is less than 4 hours. It should be noted that don't steal, not to put the electric Cup under the bed, heating or cooking. So once in a hurry to go out working, forget cut off the power, long after power up, glass stem will cause the line of fire.
⑥ in readership through radio, television broadcasts, to turn the power off time, when people leave the room, to pull the power plug.
⑦ When participating in public activities, as far as possible not to smoke. If the wish to smoke, cigarette or match rods do not casually throw. To be placed in an ashtray or spittoon. Otherwise discarded cigarette butts or match rod due to wind, kicking and so on get bed, desk, where combustible substances that can cause a fire. Because the surface temperature of the cigarette butts were very high, usually ranging from 200-300 ° c, up to 700 Center-800 degrees centigrade. While most of the combustible material to ignite in cigarette surface temperature, such as paper 130 ℃, 250 ℃, pine. So, while smoking a cigarette or match rod throw is very dangerous. In particular, throw in the elevator shaft, garbage and cable shaft riskier. Because in these parts of combustible many, very easy to start a fire accident.
⑧ lived in the guesthouse, hotel guests not to smoke in bed, smoking in bed in particular drink. Prevent sleep after cigarette out on fire in bedding. Elder elderly and the sick in bed for smoking, should someone taking care of friends.
⑨ Theatre, Club for play need actors to have smoking dedicated people management, prevent will throw cigarette butts to a screen or set on fire.
⑩ When participating in public activities, to suppress flammable and explosive articles into. Because flammable or explosive materials in the event of fire, fire and explosion. Such as theatre, Club performances, the use of time to the paper, firecrackers, Fireworks, flammable and explosive substances, there should be special guardianship, and keep away from combustible materials.
11. public power, the use of candles, such as lighting, far away from combustibles and fixed in non-combustion of materials. At the same time the scene cannot leave, when staff to do other work on temporary leave the scene, to extinguish the candle. Prevent the candle until the last or reversing leads other combustible fire, causing fire.
12. the installation of electrical equipment, be sure to follow the rated current installation. Never install the Super capacity.
