After the fire in Jiangxi, some netizens analyzed itThe tragic process may be: smoke was found on the second floor, everyone thought that the floor was not high, and ran out of the building in 10 seconds and 20 seconds, at this time the smoke in the classroom or corridor was forty or fifty degrees, but the more you ran out, the higher the temperature, when you ran to half a floor or close to the first floor, the temperature of the smoke reached one or two or even six or seven, and the people in front of them would stop or run back, and people would scream and make sounds, and the smoke would instantly enter the body ......Don't say you can't bear to rush out, think about what it's like to splash 100 degrees of boiling water on you? How does it feel to drink a sip of 100 proof water? What's more, how much smoke is there! Will you not panic! The moment the smoke enters the body, blisters will appear in the nasal cavity, mouth, and trachea, and you will be suffocated ......
Another netizen thinks:As a Registered Fire Engineer, it is recommended to deal with a fire as follows:
1. The staircase is blocked by thick smoke (no visibility of more than 1 meter) and never cover your head, and most of the corpses are on the stairs after the fire. An adult will fall unconscious in 10 seconds in thick smoke, and stepping on any corpse and other debris in the thick smoke will almost certainly die.
2. Jumping windows below the 3rd floor, the probability of survival is high, and it is not considered if it is high.
3. There are no conditions for stairs and jumping out of windows to escape, and you can try to go down to the roof to wait for help.
4. Wet your clothes with water, cover your mouth and nose, hide in a bathroom with a window and no combustibles, and wait for help, with a high survival rate.
5. Cover your nose and bend your head during activities in thick smoke, the higher the smoke concentration.
In the face of the ferocity of fire, staying sane is the key to life and death. Here are some basic steps and tips for dealing with fires to help you make the right decisions in a critical moment:
First of all, quickly call the police: at the first time the fire spreads, immediately pick up **, dial 119, and send an emergency help signal to the fire department.
Then, stay calm: try to calm yourself down and quickly assess your surroundings to determine the location and spread of the fire.
Before opening any door, check the doorknob temperature: gently touch the doorknob with your back hand, if the doorknob is hot, then the other side of the door may be a raging fire.
When crossing the smoke zone, pass in a low position: the smoke rises upwards, so the air close to the ground is relatively fresh. Try to bend over or crawl forward to reduce the chance of inhaling toxic fumes.
Use a damp cloth to protect your airways when crossing smog areas: If possible, cover your mouth and nose with a damp towel or clothing to reduce respiratory irritation from smoke.
In the event of a fire, never use the elevator: the elevator may fail due to a power failure, choose to use the stairs for evacuation.
If it's safe to do so, close doors and windows: Closing the doors and windows behind you can effectively stop the fire from spreading, buying yourself and others more time to escape.
In a fire, make sure there is no source of fire on your body: if your clothing catches fire, don't panic and roll on the ground immediately to extinguish the flames.
If the fire is small and you have the knowledge, consider using a fire extinguisher: if used correctly, you can quickly extinguish the fire and prevent it from spreading.
When entering any building, keep in mind the "two lines of one": i.e. two exits and one security line. Know and remember possible escape routes in advance so that you can evacuate quickly in case of emergency.
Once evacuated, do not return to the fire: No matter how precious the item, do not return to the fire to look for it.
After the firefighters arrive at the scene, they will give specific evacuation instructions and follow up on the official instructions: follow the instructions of the firefighters and evacuate in an orderly manner.
After evacuation, no matter how well you feel, you should seek medical attention as soon as possible to check your respiratory tract: smoke from a fire can cause harm to your respiratory tract, and timely check-ups can ensure that you are in good physical condition.
Following these basic guidelines, and doing relevant safety and escape training regularly, can bring more safety to you and those around you in an emergency. Remember, the mastery of safety knowledge and the maintenance of mentality are your biggest talisman in the fire.

Do high-rise fires run up or down?
When a high-rise building is hit by fire, the choice of escape direction becomes a life-and-death decision. Here are some urgent guidelines to follow when facing fire and smoke:
First, assess the location of the fire source: if the fire starts on a lower floor, the smoke will spread upwards with the thermals. So, in theory, an upward escape might take you away from areas with thicker smoke and closer to cleaner air.
Second, pay attention to the smoke concentration: in a smoke-filled environment, never walk upright, the smoke will float upwards because it is light. Try to take a low position, such as bending over or crawling, to reduce the risk of inhaling toxic fumes and look for potential escape routes along the ground.
In addition, follow evacuation instructions: At the scene of the fire, fire safety personnel will give professional escape advice according to the actual situation. Follow their instructions and evacuate quickly according to the designated route.
Also, look for alternative exits: If the source of the fire is on a higher floor, or if the downward route is blocked by smoke, quickly look for other safe exits, such as alternate stairs or dedicated escape routes.
In specific cases, use the fire elevator: If the fire elevator is operating normally and the fire does not affect its safe use, the fire elevator can be used to quickly evacuate.
Finally, consider an escape outside the window: When all regular escape routes are blocked, try using escape equipment outside the window, such as an escape rope or escape ladder, if possible.
Speed is key during the escape process, while trying to avoid inhaling toxic fumes. If you encounter difficulties, such as being trapped in an area, try to find a closed room, keep your respiratory system clean, and wait for help to arrive.
Remember, every second can matter to your life, so it's crucial to be calm and act quickly in an emergency. By following these guidelines, we can add an extra layer of safety to ourselves and others in the event of a fire.
