Why do fires happen, and why do they cause fires?

Explain the cause of the fire, etc.

There are many reasons for fires, mainly natural fires, caused by thunder, ground fires caused by volcanoes, and spontaneous combustion of dead grass and fallen leaves on the ground**, it is said that crows are arsonists, but the most important thing is the human factor, the most popular in ancient China is arson, whether it is marching or chasing, or daily, retaliation, to play with fire, even in modern times, China's popular burning of paper, is also not a small source of fire, refers to the coverage area, nationwide, a certain year in my local wheat harvest season, has begun to harvest, there is an old lady on the wheat field to burn paper, a gust of wind, the burning paper flew down to the wheat field, the whole wheat field was burned, the alarm was called, the fire did not contribute much, because the area was too large, the people lined up in rows, digging soil and throwing soil to the place where the fire was burning, the east fire burned a piece of green wheat, the fire could not pass, the west and the south were the road, the north was the building, and the fire began to be lit from the west, and the small temple was pushed by someone at that time, and the kind of people were pushed down, everyone had an atmosphere, the old lady ran away, it is said that no one was caught, after two years, someone built up the small temple, which was stronger and bigger than before, It used to be pure brick, and then it was concrete, and now it still exists in 2021, and it's on the side of the road, on the side of the farmland.

Because there are three elements to fire, if the three elements are complete, then it is easy to cause a fire.

1. Open flame fire.

The most common source of fire is the various open flames lit by people who mainly use cigarette butts.

2. Fire of electrical equipment.

The electrical equipment used by enterprises and all walks of life can burn combustible gases and combustible substances due to overload operation, short circuit, and poor contact, and must be safe and protected in use.

3. High temperature fire.

Dry firewood, wood, wood near the stove or flue, combustible dust and fibers that accumulate on the high-temperature steam pipes; Paper, clothing, etc., next to high-power light bulbs, will cause burning if they are baked for too long. Stir-fried food or other substances that accumulate without heat dissipation, or are packed in bags, will also accumulate heat**, and attention must be paid to heat dissipation.

4. Chemical reaction.

When substances of different properties meet, they can sometimes cause spontaneous combustion. If the oil comes into contact with oxygen, a strong chemical reaction will occur, causing combustion.

5. Thunder and lightning. Lightning strikes and electrostatic sparks in nature can cause disasters due to the combustion of combustible gases and combustible substances.

6. Impact sparks.

Friction and impact will cause fire, such as the impact of iron and cement, which will cause flowers, and flammable materials can cause disasters.

Electrical equipment fire: The electrical equipment used by enterprises and all walks of life can burn combustible gases and combustible substances due to overload operation, short circuit, and poor contact. High temperature fire:

Dry firewood, wood, wood near the stove or flue, combustible dust and fibers that accumulate on the high-temperature steam pipes; For example, paper and clothing next to high-power light bulbs can cause burning if they are baked for too long. Chemical reactions: Substances of different properties meet and sometimes cause spontaneous combustion.

If the oil comes into contact with oxygen, a strong chemical reaction will occur, causing combustion. <

1. Electrical equipment fire: The electrical equipment used by enterprises and all walks of life can burn combustible gases and combustible substances due to overload operation, short circuit, and poor contact.

2. High-temperature fire: dry firewood, wood, wood, and woodware close to the stove or flue, and combustible dust and fibers that are tightly gathered on the high-temperature steam pipeline; For example, paper and clothing next to high-power light bulbs can cause burning if they are baked for too long.

3. Chemical reaction: the encounter of substances with different properties sometimes causes spontaneous combustion. If the oil comes into contact with oxygen, a strong chemical reaction will occur, causing combustion.

4. Lightning: For example, lightning strikes and electrostatic sparks in nature can cause disasters due to the combustion of combustible gases and combustible substances.

5. Baking: In the process of refining and baking, due to poor temperature control or automatic control failure, it will catch fire and even cause disaster.

6. Fried food is not dissipated: fried food or other substances are piled up without heat dissipation, or packed in a bag, and heat will also be gathered, so attention must be paid to heat dissipation.

7. Heat treatment workpieces of the enterprise: stacked on the ground with oil stains, or stacked next to flammable products (such as wood), which is easy to cause disasters.

A common safety hazard in the home.

1. If the gas is not turned off, it will be poisoned.

Second, the cable switch is often disconnected.

3. Electrical appliances take too long.

Fourth, the wire contact is poor.

5. The wood-burning stove will fall out of the spark.

Sixth, lighting candles will lead to disaster.

7. If the hot water bottle is not put properly, it is easy to cause burns.

8. Playing with lighters is prone to fire.

9. Playing with fireworks and firecrackers are prone to fires, and wildfires are prone to fires.

Ten. 1. Improper storage of flammable and explosive materials is prone to safety accidents.

Ten. 2. Littering cigarette butts is prone to fire.

Ten. 3. The socket is too low and easy to be electrocuted.

Ten. Fourth, the wire is damaged and aging and prone to fire.

Ten. Fifth, it is easy to burn with boiling water.

Ten. 6. Wet hand switching power supply is easy to be electrocuted.

Ten. 7. Gas stoves are prone to fire without quality inspection.

Ten. 8. Have you noticed the 8 family safety hazards that are often overlooked when baking and warming quilts are prone to fire in winter? Many fire accidents occur because of not paying attention to small details. Therefore, in daily life, you must pay attention to the following points:

Place the fire extinguisher in an easily accessible location; Keep lighters and other items that may cause disasters away from the bedroom; Please do not leave the kitchen in the middle of cooking; Microwave ovens, ovens and other electrical appliances must be equipped with special sockets; There should not be more than 3 plugs on the electrical socket....Learn more about the content of the stamped map to understand the timely elimination of fire hazards, and always pay attention to fire safety!
