Essay on safety and ensuring growth

Safety ensures growth

Fire safety is very important, it is related to our lives. If you do not have a correct understanding of fire protection knowledge, the consequences will be disastrous. In recent years, schools have become a hot spot for fires, and more and more students are playing with fire. Hotel explosion search and rescue dogs sniffed out trapped persons. "A hotel exploded near the city stadium. All departments are requested to rush to the scene for rescue." The fire command center received an "alarm" of an explosion in a hotel. Two fire motorcycles on duty near the stadium were the first to respond. He rushed to the scene of the incident immediately and used the high-efficiency and high-pressure water mist fire extinguishing system equipped on the vehicle to reduce the temperature of the scene. Soon, the rescue convoy arrived and the fire-fighting team laid hoses from water tankers. The warning team set up warning isolation piers and demarcated the warning area. Since the building components were criss-crossed on the ruins of the collapsed building, in order to search inside, the rescue team used hydraulic shears and expanders and toothless saws to cut off obstacles such as steel bars and wooden boards, and opened a life-saving passage into the house. According to the rescued people, there was another person trapped in the room, whose life or death was unknown. Two search and rescue dogs, led by their handlers, entered the ruins to look for signs of life. When the search and rescue dogs barked and the rescuers determined the general location of the trapped persons, the search and rescue team members used radar life detectors to locate the trapped persons, and used "Snake Eyes" audio and video life detectors to establish contact with the buried persons. The multi-functional emergency rescue vehicle started the truck-mounted boom at the rear of the vehicle, stretched it over the buried people, and lifted large building components away. Medical staff immediately stepped forward and carried the injured people on stretchers into ambulances and sent them to the hospital. The commander then decided to have fire tanks bulldoze the ruins after the explosion to eliminate the danger. An orange fire tank drove in, and under its powerful impact, all the broken walls were knocked down. A fire broke out in the stadium. The ladder truck "reached out" to save people. The danger had just been resolved. Then, followed by several explosions, a "fire" broke out in the Yizhong Stadium where an "important event" was being held, and thick smoke suddenly billowed out. The fire command center immediately mobilized more than 100 commanders and fighters from the seven nearest fire squadrons and 24 firefighting vehicles of various types to rush to the scene. The fire spread rapidly, with thick smoke billowing throughout the Yizhong Stadium, and two people were trapped in the fourth-floor corridor of the stadium. At this time, the ladder truck chose a favorable position to park under the trapped people. The five lift trucks raised on the scene were, from south to north, an 18-meter-high spray truck, a 53-meter ladder truck, a 30-meter ladder truck, and a 53-meter curved ladder truck. Arm climbing truck and 32-meter high spray truck. After the 53-meter ladder truck was raised, it took less than 60 seconds to transfer the trapped people to the ground. At this time, 24 water belt lines on the ground were also ready to supply water. Five water cannons sprayed in the air tightly surrounded the burning area. Six large-caliber vehicle-mounted water cannons launched a heavy attack. The fire was gradually controlled. About 10 The fire was completely extinguished within minutes. This is really a bloody lesson. You must know that you only live once and there is no possibility of another life. Therefore, we must cherish it and not dedicate our precious lives to this ruthless fire. For our health, we should do the following: 1. Escape rehearsal and stay calm in case of danger. Everyone should have a clear understanding of the structure and escape routes of the building where they work, study or live, and can concentrate when necessary. Organize emergency escape rehearsals to familiarize everyone with the fire protection facilities in the building and self-rescue escape methods. This way, when a fire breaks out, you won't feel like you have no other options. Remember: Previewing beforehand will get twice the result with half the effort. 2. Familiarize yourself with the environment and remember the exits. When you are in an unfamiliar environment, such as staying in a hotel, shopping in a shopping mall, or entering an entertainment venue, for your own safety, be sure to pay attention to the evacuation passages, safety exits, and stair directions, etc., so that you can escape as soon as possible at critical moments. on site. Please remember: When it is safe, you must be prepared for danger in times of peace and reserve a path for yourself. 3. Passage exits, unobstructed Stairs, passages, safety exits, etc. are the most important escape routes in the event of a fire. They should be kept clear and unobstructed. Do not pile up debris or set up gates and locks, so that you can pass safely and quickly in an emergency. Remember: if you cut off your own retreat, you will surely die. 4. Put out small fires and benefit others. When a fire breaks out, if it is found that the fire is not large and has not yet posed a great threat to people, when there are enough fire-fighting equipment around, such as fire extinguishers, fire hydrants, etc., you should strive to put out the small fire. Control and extinguish; never scream and run around in panic, ignoring a small fire and causing a major disaster. Remember: it’s a matter of time to put out “incipient fires.” 5. Stay calm, know the direction, and evacuate quickly. If you encounter a sudden fire and face heavy smoke and fire, you must first force yourself to stay calm, quickly judge the dangerous and safe locations, decide on escape methods, and evacuate the dangerous area as soon as possible.

Never blindly follow the flow of people, crowd each other, and rush around randomly. When evacuating, be careful and run towards bright places or open areas outside. Try to run below the floor. 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. Remember: Only when people are calm can they come up with good ideas. 6. Don’t go into danger and don’t be greedy for money. In a fire scene, human life is the most important thing. If you are in a dangerous situation, you should evacuate as soon as possible. Don't waste your precious escape time on dressing or looking for and moving valuables out of shyness or concern for valuables. People who have escaped from dangerous situations must not return to dangerous areas and throw themselves into a trap. Please remember: if you keep the green hills, you won’t have to worry about running out of firewood. 7. Simple protection. When escaping while crawling with your nose covered, you must avoid smoke poisoning and suffocation when passing through a smoke-filled route. In order to prevent the smoke from being choked from the fire scene, you can use a towel or mask to cover your nose and crawl to evacuate. Smoke is lighter than air and floats upward. Evacuation close to the ground is the best way to avoid inhaling smoke and filter out poisonous gases. When passing through a firework blockade area, you should wear gas masks, helmets, flame-retardant and insulating clothing and other protective equipment. If you do not have these protective equipment, you can pour cold water on your head and body or use wet towels, wet quilts, wet blankets, etc. Wrap up your head and body before rushing out. Remember: It’s better to have several protective tools at hand than bare hands. 8. Make good use of passages and do not use elevators. Buildings designed and built according to regulatory standards will have more than two escape stairs, passages or safety exits. In the event of a fire, you should choose to enter a relatively safe stairway according to the situation. In addition to using the stairs, you can also use the building's balconies, window sills, skylights, roofs, etc. to climb to surrounding safe places. You can also escape by sliding down the stairs along the protrusions in the building structure such as downspouts and lightning protection lines. In high-rise buildings, the power supply system of the elevator may be cut off at any time during a fire or the elevator may be deformed due to high temperature, causing people to be trapped in the elevator. At the same time, because the elevator shaft is like a continuous chimney and goes straight to each floor, toxic smoke is a direct threat. The lives of the trapped people are at risk, so never take an ordinary elevator to escape. Remember: taking an elevator is extremely dangerous when escaping. 9. Slow descent escape and slide rope self-rescue. High-rise and multi-story public buildings are generally equipped with high-altitude slow descent devices or lifeline ropes. Personnel can use these facilities to safely leave dangerous floors. If these specialized facilities are not available, and the safe passage is blocked and rescuers cannot arrive in time, you can quickly use the ropes around you or sheets, curtains, clothes, etc. to make a simple lifeline, and wet it with water to remove it from the window sill or The balcony slowly slides along the rope to the floor or ground below for safe escape. Remember: if you are brave and careful, a lifeline is always at your side. 10. Stay at the evacuation site and wait for help. If you touch the door and it feels hot, then once you open the door, flames and smoke will inevitably hit you. The escape route was cut off and no one could rescue him for a short time. At this time, measures can be taken to create a refuge place and wait for help. First, close the doors and windows facing the fire tightly, open the doors and windows facing away from the fire, plug the door cracks with wet towels or wet cloths, or soak the quilts with water to cover the doors and windows, and then keep drenching them with water to prevent the penetration of fireworks and stay in the room. , until rescuers arrived. Remember: Why should a strong shield be afraid of a sharp spear? 11. Toss slowly and gently, and seek assistance. People who are temporarily trapped by fireworks and unable to escape should try to stay on balconies, windows and other places where they are easy to be discovered and where they can avoid fireworks. During the day, you can shake brightly colored clothes out of the window or throw light dazzling objects; at night, you can use a flashlight to flash in the window or tap on things to send out an effective distress signal in time and attract the attention of rescuers. Because firefighters always grope along the walls when they enter the room, when they are suffocated by smoke and lose the ability to save themselves, they should try to roll to the wall or door to facilitate firefighters' search and rescue; in addition, rolling to the wall can also prevent the structure of the house from He fell and hurt himself. Remember: Only by fully exposing yourself can you strive to effectively save yourself. 12. When the fire reaches you, do not run away. If people on the fire scene find that their bodies are on fire, they must not run away or slap them with their hands, because running or slapping will create wind, which will accelerate the replenishment of oxygen and promote the fire. When your clothes are on fire, you should quickly take off your clothes or roll on the spot to extinguish the flames. It is more effective if you can jump into the water in time or have someone pour water on you or spray fire extinguisher. Please remember: Even if you are embarrassed by rolling around on the spot, you can avoid being burned by the fire. 13. There is a skill in jumping off buildings to survive despite the damage. People who are exposed to the smoke of fire often suffer from extreme mental terror and are close to collapse. The panic can easily lead to desperate and harmful behaviors, such as jumping off buildings to escape.

It should be noted that the method of jumping from a building should only be adopted when firefighters prepare life-saving air mattresses and direct the jump, or when the floor is not high (generally below 4 floors) and the fireman will burn to death without jumping. Even if there is no way out, if your life is not seriously threatened, you should calmly wait for rescue by firefighters. Jumping from a building also requires skills. When jumping from a building, you should try to jump to the middle of the air cushion or choose a direction with a pool, soft awning, grass, etc.; if possible, try to hold some soft items such as quilts, sofa cushions, or open a large umbrella to jump down to slow down the impact. If you jump from a building with bare hands, you must grab the window sill or balcony and let your body hang down naturally to minimize the vertical distance. Before landing, you should hold your head with your hands and bend your body into a ball to reduce injuries. Although you can survive by jumping off a building, it will cause some damage to your body, so be careful. Please remember: jumping off a building does not mean committing suicide, the key is to have a way. 14. Fire smoke kills invisible people. In the "2.15" fire at Zhongbai Commercial Building in Jilin City, most of the people who died on the scene died of smoke suffocation and poisoning. The main component of smoke in fires is carbon powder, as well as large amounts of toxic gases such as carbon monoxide, carbon dioxide, and hydrogen sulfide, which are very harmful to the human body. According to data, casualties caused by lack of oxygen and smoke damage during fires can reach 50-80% of the number of fire deaths. So, what are the main hazards of smoke? First, when the oxygen content in smoke is lower than the normal required value, people's ability to move will be weakened, their intelligence will be confused, and they may even faint and suffocate. When the content of various toxic gases in the smoke exceeds the minimum concentration allowed by normal human physiology, poisoning and death will occur; second, the light-dampening properties of the smoke affect the safe evacuation of personnel and fire fighting. The smoke particles in the smoke block visible light, which greatly reduces visibility, and the smoke is extremely irritating to people's eyes, making it difficult for people to open their eyes and affecting the evacuation speed; third, the terror of the smoke causes people's psychological panic. Especially when flashover occurs, flames and smoke rush out of the door and window holes, and the fire is raging and the smoke is billowing, causing people great fear and causing chaos during evacuation. Therefore, how to prevent fire smoke is crucial for people to escape. Experience tells us that once surrounded by fire, smoke prevention measures must be taken regardless of whether there is smoke nearby. The simplest method is the towel smoke prevention method. Folding a towel and covering your mouth and nose will play a very good role in preventing smoke. If the dry towel is folded in 16 layers, the smoke elimination rate will reach more than 90%. It is appropriate to fold a towel into 8 layers. At this time, the smoke elimination rate will reach more than 60%. Experiments have shown that in this case, people walking slowly in a 15-meter-long corridor filled with strong irritating smoke will not feel irritating; wet towels will increase breathing resistance and cause difficulty in breathing. Therefore, when using wet towels, the water content of the towel should be controlled to less than 3 times the weight of the towel itself. When using a towel to cover your mouth and nose, be sure to increase the area of ??the filtered smoke as much as possible and cover your mouth and nose tightly to avoid burning the respiratory system by hot air. When passing through smoke areas, never remove the towel from your mouth and nose, even if you feel increased breathing resistance. Once removed it may cause immediate poisoning. When rescuing trapped people at a fire scene, the face and head of the rescued person should also be covered with a towel to avoid burns when passing through the fire area. If the rescued person has been burned, the wound can also be covered with a towel to prevent smoke particles from infecting the wound. We must always remember: not playing with fire is the best way to stay away from fire!
