Common Causes of Fire Awareness in Factory Enterprises, Fire Classification and Harm to Harm

First, the common causes of corporate fire
(a) careless use of fire. If a fire is used or the lights are inadvertently lit, fires caused by the reignition of matches that have not extinguished, cigarette butts, and fire ash will be lost.
(2) Bad use of fire equipment. Such as stoves, fire pits, fire walls, chimneys, etc. do not meet the requirements of fire prevention, close to the flammable structure, and long years of disrepair, cracks fire, causing flammable materials to catch fire.
(c) Reverse operational procedures. For example, welding, baking, smelting, wearing shoes with iron nails at places where sparks are forbidden, knocking on iron, smoking in rooms filled with gasoline vapors, acetylene, oxygen, etc., or using open flames cause fires.
(4) Improper installation and use of electrical equipment. Such as electrical equipment and its installation does not meet the specifications, poor insulation, load, electrical circuit short circuit, wrapping paper on the light bulb? 觳嫉瓤 铮 铮 医 医 医 医 医 医 医 医 医 抢 缯 缯 缯 缯 缯 缯 缯 缯 缯 缯 缯 缯 缯small boat? knock home from Fiji thatch Wren Zheng? Inspector phosphorus knock cricket gallery Shang Shu? br /> fire (five) caused by the explosion. Explosion of explosives, explosion of chemical dangerous goods, explosion of combustible dust fibers, explosion of combustible gas, explosion of flammable non-flammable liquids, and explosion of certain production and electrical equipment often cause great fires.
(six) spontaneously catch fire. Oil-soaked cotton fabrics, peat, coal, steel, iron, steel, iron, iron, yellow phosphorus, phosphine, etc., all easily ignite and catch fire. In addition, there are substances such as potassium, sodium, lithium, calcium and other non-water contact that is fire; there are chemical products, such as potassium permanganate and glycerol mixed together and immediately catch fire. Therefore, corresponding fire prevention measures must be taken in accordance with the characteristics of the returned materials.
(7) Electrostatic discharge, lightning strike and fire. Lightning strikes are easy to catch fire and are often seen by everyone. However, electrostatic discharges tend to be less noticeable. For example, rotating belts, flammable liquids flowing along the tubes, combustible dust, etc., are all prone to static electricity. If there is no corresponding measure to eliminate static electricity, electrostatic discharge electrodes are prone to sparks and fire. Many oil depots catch fire, which is caused by the reason.
(8) Arson. There are counter-revolutionary arson attacks, accidental arson attacks, and psychiatric patients arson.
Second, the concept of fire and harm to the human body
Definition:? Where at time ta fresh Shen Wei accounting frequency Na Dao avoid posting Fei Ji Pu silly brain toe Γ frame 7 Wren throw bo br /> A type fire:????? Solid material fires. The returned substances are usually of organic nature and generally produce burning embers when burned.
 Class B fires: Liquid or fused solid material fires.
Class C fires: gas fires.
 Class D fires: Metal fires.
Class E fires: Live fires. The object is charged and fired.
 Class F fires: Cooking items (such as animal and vegetable oils) inside a cooking appliance fire.
(1) The amount of ton oxygen in an oxygen-deficient normal room is about 21%, but the amount of ton oxygen in a room after a fire drops to about 6%. The reversal causes people to breathe hard, lose consciousness, and die within hours.
(B) After the high-temperature fire burns, the indoor temperature must change with the development of combustion, and the temperature rises directly. Scientific proof: When the temperature reaches 44-55 degrees, air inhales into the body, which can lower the blood pressure and cause circulatory system failure. When it reaches 70 degrees, the trachea and bronchioles will become blisters and tissue will be necrotic. It will cause pulmonary edema and suffocate. People lose their ability to escape in a 100-degree environment.
(3) The smoke and dust material is burning? It is necessary to consult with the student since the paper is printed. (14) What to do?

Such as: carbon monoxide, carbon dioxide, hydrogen chloride, nitrogen oxides, hydrogen sulfide, hydrogen cyanide, phosgene and other toxic gases.
Third, the main culprit of the death caused by fire
1. Electricity: The fire caused by electricity cannot be separated from the power supply and electricity system consisting of electricity equipment, transmission lines, and electrical appliances. The reasons are various, overload short-circuit, poor contact, arc sparks, poor quality wire, aging leakage, lightning strikes, and static electricity.
Lethality: In the ten years between 1992 and 2010, there were 363,580 electrical fires in China, ranking top in electrical appliances.
2. Smoke: The smoke in a fire is a fire. Thermal decomposition is the result of this phenomenon. In the case of fire, it is not a good idea. ? Executive small br /> destruction:? at home and abroad a large number of fire cases statistics show that damage due to fire them, by flue gas directly lethal 1/3 2/3. Some of those who were burned to death were smoked first. Studies have shown that if a drunk man or a sleeper is locked in a room with a closed window and door, the smoke from the burning of a pillow is enough to kill him.
3. Wind: The fire of the stars can be rekindled, and the wind can make the fire rekindled. Can make the general fire source into a dangerous fire, a small fire into a fire, fly the fire up to a distance of up to 2,7 kilometers.
4, lock: Although it can not directly harm human lives, but countless bloodshed is not related to him. The culprit.
