Teaching process

Ⅰ. Introduction of fire news records in our city:

At about 3:30 in the morning on March 5, 20__, the nurse of the welfare home found smoke coming out of the door of room 2103 on the first floor of the children's department while inspecting the room. He immediately opened the door and saw a quilt on the bed in the room smoldering. There were 4 beds, with two children sleeping in each bed. The doors and windows were closed and filled with smoke. Immediately, the on-call and security guards were called to take the children out for rescue, and they used water to put out the smoldering bedding. After receiving the report, the civil affairs, public security and fire departments at the municipal and district levels rushed to the scene as soon as possible to organize rescue work. Due to being exposed to smoke for too long, eight children died despite ineffective rescue efforts. The cause of the accident was that the bedding of a mentally retarded child fell on a lit mosquito coil after he fell asleep, causing smoldering, producing a large amount of thick smoke, and causing death by suffocation.

Around 6:00 on January 31, 20__, a fire broke out in a house at No. 53 Gexin Road, Sandong Town, Huicheng District, Huizhou City. After the full efforts of the Sandong Fire Fighting Squadron and the Maidi Fire Fighting Squadron to put out the fire, the fire was finally put out. Put out, burned household appliances, and burned to death a woman, female, Han nationality, 77 years old, from Sandong Town, Huizhou City, suffering from severe dementia and unable to take care of herself),

Ⅱ. Fire self-rescue Knowledge

What should we do when encountering a fire?

(1) Fire extinguishing

The most important time to extinguish a fire is to fire it as soon as the fire starts. Putting out the fire can quickly stop the occurrence or spread of the fire. At this time, you should quickly identify the source of the fire, the type of fire, and the ignited substances, take corresponding countermeasures, and use fire extinguishers or water from fire hydrants to extinguish the fire. If these fire extinguishing equipment cannot be obtained quickly, you can use nearby materials to extinguish the fire by moistening quilts, curtains, etc. or using sand, gravel, and soil. However, if the fire has a tendency to expand and spread, you should quickly retreat to a safe inspection location.

(2) Call the police

When a fire is discovered, you should immediately dial 119 or 110 to call the police. You can also shout loudly, knock on the door, and wake others up to know about the fire. When calling the police, do not panic. Be sure to specify the address, location, building conditions, etc. where the fire occurred so that firefighting vehicles can go to the rescue in time.

(3) Escape

1. Stay calm, keep a clear head, and do not follow blindly.

When a person's life suddenly faces a critical situation, it is easy to lose normal thinking and judgment due to panic. When hearing or seeing someone running in front, the first reaction is to blindly Follow them, such as: jumping out of the window, jumping off the building, escaping (hiding) into the toilet, bathroom, or door corner. When encountering a fire, you should first keep yourself calm, quickly judge the dangerous and safe locations, use your usual knowledge of fire self-rescue and escape, decide on escape methods, and evacuate the dangerous area as soon as possible.

When evacuating, be careful not to take the elevator, because the power supply is often interrupted during a fire and you will be trapped in the elevator. You should escape through the safe passage. When you can walk along the wall, you can enter when you reach the safety door to avoid walking. If you go too far, try to run toward a bright place or an open area outside. If the passage has been blocked by fireworks, you should leave in the direction of the fireworks and escape outdoors through balconies, transoms, rooftops, etc.

2. Keep the green hills and don’t worry about running out of firewood. Don’t delay your escape because of greed for money.

In a fire scene, human life is the most important thing. If you are in danger, you should evacuate as soon as possible. Don't waste your precious escape time on dressing or moving valuables away because you are shy or concerned about your valuables. People who have escaped from dangerous situations should not return to dangerous areas and throw themselves into a trap.

3. Take simple protection, crawl forward, and do not run upright into the wind.

When escaping through smoke-filled routes, prevent smoke poisoning and suffocation. In order to prevent the smoke from being choked in, you can use towels and masks wet with water to cover your nose, and crawl on your stomach to evacuate. The smoke is lighter than the air and floats in the upper part. Keeping it close to the ground and evacuating it is a way to avoid inhaling the smoke and filter out the poisonous gas.

4. Find a safe place to take refuge, stay there, and don’t blindly run toward the light.

If various escape routes are cut off, you should retreat indoors and close the doors and windows. If possible, water the doors and windows to delay the spread of the fire. At the same time, you can throw small objects outdoors to attract others' attention. You can use a flashlight to send out a distress signal at night. Do not turn toward the light. This is because in emergency and dangerous situations, due to human instinct, physiological and psychological decisions, people always escape in the direction of light and brightness. The bright light means the hope of survival, and it can provide guidance for escape. It is easier to escape by avoiding blind collisions, but at this time the power supply may have been cut off or caused a short circuit, jump, etc. The light and bright place is the most dangerous place.

5. Escape slowly and slide the rope to save yourself. Never take the risk of jumping off the building.

High-rise and multi-storey public buildings are generally equipped with high-altitude descent devices or lifeline ropes. Personnel can use these facilities to safely leave dangerous floors. If these special facilities are provided and the safe passage is blocked and rescuers cannot arrive in time, never give up the will to survive. At this time, try to calmly use the items or features on the scene to try to escape.

Ⅲ. Summary:

As long as we are careful everywhere, pay attention to safety, master the knowledge of self-rescue and self-protection, exercise our ability to protect ourselves, and deal with all kinds of situations we encounter tactfully and bravely. If there are any abnormal situations or dangers, they can grow up healthily.

(2) When heating, be sure to open windows in the house for ventilation to prevent gas poisoning.

When using gas appliances (such as gas stoves, gas water heaters, etc.), indoor ventilation should be fully ensured to maintain sufficient oxygen to prevent gas poisoning.

3. What to do if a fire occurs

The climate is drier in winter. Playing with fire is strictly prohibited to prevent fire accidents. Inflammable materials can be easily ignited, so fire prevention is particularly important. The following points are emphasized:

(1) No students are allowed to bring matches, lighters or other tinder into school, and tinder in the laboratory is not allowed to be taken outside. .

(2) You are not allowed to bring other items into the campus. You should also be careful to stay away from these dangerous items outside the campus when visiting relatives and friends.

Four , Understand some causes of fires

(1) Understand the causes of fires caused by hair dryers

First, when the hair dryer is in use, it is necessary to go away due to other things (such as answering the phone, someone knocking on the door) After opening the door, etc.), he casually put the hair dryer on the wooden table and completely forgot about using the hair dryer. As a result, he left it for a long time, and the high temperature of the hair dryer shell ignited combustible materials.

Secondly, if you encounter a power outage when using a hair dryer, and do other things or go out without cutting off the power supply, after the power is restored, the heating wire of the hair dryer will be heated for a long time, and the temperature will rise, causing fire.

(2) Causes of fires caused by cigarette butts

Although cigarette butts are a small fire source, they can cause many substances to catch fire. The surface temperature of cigarette butts is 200~C~300~C, and the core temperature is 700~C~800~C. The ignition point of general combustibles is mostly lower than the surface temperature of cigarette butts, such as paper at 130~C, cloth at 200~C, and pine. is 250~C. The burning time of a cigarette is 4 to 15 minutes. During this period of time, general combustibles can be ignited. After a period of smoldering, they will catch fire. According to tests under natural ventilation conditions, if a cigarette butt is thrown into sawdust with a depth of 5 cm, after 75 to 90 minutes of smoldering, a flame will begin to appear: if a cigarette butt is thrown into wood shavings with a depth of 5 to 10 cm, there is a 75% chance that it will smolder. It will start burning in 60 to 100 minutes. For chemical hazardous materials, the open flame of cigarettes will immediately cause them to burn and explode.
