On April 8, a fire broke out in a livestock technology chicken farm in Sanheli, Huwei Town, Yunlin County. More than 14,000 chickens were either burned to death or choked to death by thick smoke. Because the eggs in the chicken farm are used to develop vaccines, the internal equipment is advanced, not only water-cooled air-conditioning facilities, but also automatic egg collection system, the loss is tens of millions of yuan. The preliminary analysis may be caused by fire from the wires.
The fire alarm occurred at around 11:00 p.m. on April 8. Due to the confined space, the fire quickly spread inside. The fire brigade reportedly rushed to rescue the factory, and the factory was burned within 1 or 2 hours.

This animal husbandry technology chicken farm is different from the general chicken farm. It mainly develops vaccines from eggs, covering an area of thousands of pings, and raises chickens in closed iron houses, most of which are breeding chickens and laying hens. The chicken house is designed as two-story buildings. The entire factory has water-cooled air conditioners and an automatic egg collection system. You must wear protective clothing and thorough disinfection when entering and leaving.
The fire brigade inspected the fire scene on April 9. None of the more than 14,000 chickens survived. They were either scorched by the fire or choked to death by smoke, and the factory was distorted and deformed. It is initially judged that the fire may be caused by the wires. The person in charge of the company surnamed Liu said heartbrokenly that the equipment in the chicken farm is different from the general market. The casualties and injuries of chickens are not counted. The equipment alone costs tens of millions of yuan, and the losses are heavy! !
The hazards of thick smoke
1. Contains a large amount of toxic gas
Carbon monoxide (CO) is one of the main combustion products that cause death in fires. It can hinder the delivery of oxygen in the human blood, cause symptoms such as headache, collapse, and disorders and muscle mediation disorders. When the concentration of carbon monoxide in the air reaches 1.3% , a person will lose consciousness after breathing for two or three breaths, and continuous breathing for 13 minutes will lead to death. It is understood that the carbon monoxide content in the flue gas generated by commonly used building materials during combustion is as high as 2.5% . The flue gas generated in the fire also contains a large amount of carbon dioxide (CO2) . Under normal circumstances, carbon dioxide accounts for about 0.06% in the air. When its concentration reaches 2% , people will feel difficulty breathing. When it reaches 6% and 7% , people will suffocate and die.
2. High temperature burns the human body and respiratory organs
Extremely high temperature smoke can form a fire within 2 minutes, and it can also pose a threat to people who are far apart. Inhaling thick smoke in a fire mainly damages the respiratory system, which includes inhalation injuries, namely respiratory burns and complications caused by respiratory system. After severe burns, the incidence of respiratory complications is also very high, with common upper respiratory tract obstruction, acute respiratory insufficiency syndrome and pulmonary infections. Its characteristics are early, fast and serious condition. If the prevention and treatment of is not timely and incorrect, there will be a higher mortality rate.
3. Reduce visibility and hinder evacuation and escape
Flue gas spreads in the fire field, which will reduce visibility and seriously affect people's sight, making it difficult for people to distinguish the direction of the fire development and find a safe evacuation route. At the same time, thick smoke also contains substances that is irritating to the human eyes, which makes it impossible for the human eyes to see objects normally after being irritated, and cannot distinguish the escape direction.
How to escape from thick smoke?
folding method of towel
In the fire escape, covering your mouth and nose with a wrung wet towel to filter smoke has a better effect, which is equivalent to a simple "air respirator". If the wrung wet towel is folded with 8 layers, the smoke removal rate can reach 60%, and can ensure good breathability; however, the more folded layers, the better. For example, if the 16 layers are folded, the smoke removal rate can reach more than 90%, but the breathability is poor.
Many people are familiar with the method of covering their nose with wet towels, but it should be noted that when preparing towels, you should choose cotton towels. Wet cilia towels can easily suffocate. The weather is getting dryer and the risk of fires is getting bigger and bigger. How to reduce casualties when a fire occurs? A warm towel, folded 3 layers, the smoke removal rate can reach 60%. In the fire, covering your mouth and nose with a wet towel is a simple gas mask. However, be careful that too wet towels will make breathing difficult. Therefore, when using wet towels, the moisture content of the towel should generally be controlled below 6 times the weight of the towel.
Touch the door handle to test the temperature
When a fire occurs, touch the door handle and feel the temperature of the door handle. If you find that the door handle temperature is very high or there is thick smoke when you open the door, you should retreat and wait for help. Use bed singles and clothes to block the door cracks, splash water to cool down and prevent smoke (the entrance door of high-rise residential buildings is generally fire door , and can withstand fire for more than 1 hour ).
sends a distress signal in time
calls the "119" notification position in time, removes the curtains at home and places them away from the window, and sends a distress signal in prominent locations such as the balcony. When a high-rise building catches fire, the person trapped in the fire waving brightly colored towels at the window as a distress signal, which can attract the attention of rescuers to get rescue from firefighters.
Once a fire comes, it often catches people off guard. So this requires us to learn more fire protection knowledge in daily life; when a fire comes, keep a clear mind and escape smoothly according to scientific escape methods. When fire safety hazards are found, clean up in time or call 96119 to report! Pay attention to observing evacuation channels and exits and formulate escape routes.
Fire safety is nothing small, you need to pay attention to it at all times and anywhere.
