There are two main aspects to teach you "ten tricks" to avoid fire casualties: first, being suffocated by smoke and toxic gases, and second, being burned by flames and strong thermal radiation.
As long as we can avoid or reduce these two hazards, we can protect our own safety and reduce the hazards. Therefore, it is possible to get a second life in a difficult situation by mastering some small skills of self-rescue in fire.
1. Fire rescue, always pay attention to the escape route. Everyone should know something about the structure and escape route of the building where he works, studies or lives, and be familiar with the fire-fighting facilities in the building and the methods of self-help and escape. In this way, in case of fire, there is no way out.
In an unfamiliar environment, we must pay attention to evacuation routes, safety exits and stairs, so as to escape from the scene as soon as possible at a critical time. 2. Put out small fires to benefit others. When a fire breaks out, if the fire is not big enough to pose a great threat to people, we should make full use of the surrounding fire-fighting equipment, such as fire extinguishers and fire hydrants, to control and put out the small fire.
Don't run around screaming in panic, don't ignore others and just "escape" yourself, and don't ignore a small fire and cause great disaster. 3. In case of sudden fire, keep calm and evacuate quickly. In the face of sudden smoke and fire, we must keep calm, quickly judge the dangerous place and safe place, decide the escape mode, and evacuate the dangerous place as soon as possible.
Don't blindly follow people, crowd each other and rush about. Only when you calm down can you come up with a good solution.
4. Get out of danger as soon as possible and cherish life. Love money like fire, life is more expensive than money. When you are in danger, it is very important to run away. You must race against time and remember not to be greedy for money.
5. Evacuate quickly and crawl forward. Don't stand when you leave the fire. Don't stand when the smoke is rolling, the sight is unclear and you can't breathe. You should climb on the ground or squat down to find a way to escape. 6. Make good use of this article. Don't get into the elevator and go to a dead end. In case of fire, you can use the safety exits such as stairs, or use the balconies, window sills and skylights of buildings to climb to the surrounding safe places, or slide down the stairs along the protrusions in building structures such as downpipes and lightning wires.
7. When the escape route is cut off and there is no rescue in a short time, you can find or create a shelter and insist on waiting for rescue. First of all, you should close the doors and windows that are on fire, open the doors and windows that are on fire, block the doors with a wet towel or cover the doors and windows with a quilt soaked with water, and then constantly spray the room with water to prevent fireworks from infiltrating and sticking to auxiliary materials.
8. Jumping off a building is skillful and won't harm your health. In case of fire, many people choose to jump off a building to escape. You should also talk about skills when jumping off a building. When jumping off a building, try to jump into the middle of the life-saving air cushion or choose the direction of pool, hood and grass. If possible, try to hold some soft objects such as quilts and sofa cushions tightly or open a big umbrella to jump down to slow down the impact.
9. Fire and your body roll on the spot. Don't run in the fire When your clothes catch fire, you should try to take off your clothes or roll on the spot to crush the flame. It is more effective to jump into the water in time or have someone water it and spray fire extinguishing agent on your body. 10. If you are in danger, don't forget to save others. Anyone who finds a fire should call "1 19" for help as soon as possible and report the fire situation to the fire brigade in time.
2. Fire safety knowledge
Fire control work is a highly knowledgeable, scientific and social work, involving all walks of life and thousands of households, closely related to economic development, social stability and people's lives.
Only by popularizing fire laws and regulations and knowledge of fire science and technology in the whole society, raising fire awareness and enhancing the ability of prevention and fighting can fire hazards be effectively prevented and reduced. Several common escape methods: 1. Try to use the facilities in the building to escape. It is an important way to strive for escape time and improve the escape rate.
(1) Use the fire elevator for evacuation and escape, but never take the ordinary elevator on fire; (2) Use indoor smoke-proof stairs, ordinary stairs and closed stairs to escape; (3) Use balconies, corridors, refuge floors, descending devices, life-saving bags, safety ropes, etc. The escape route of the building; How to prevent fire accidents Fire is a natural phenomenon. Taming fire is a friend of human beings, which brings light and warmth to people and promotes the progress of human civilization and society.
However, if the fire gets out of control and leads to a fire, it will cause great losses to people's lives and property. According to statistics, during the period of 1997, there were more than 40,000 fires in China, with more than 7,000 casualties, 8% of which were caused by children playing with fire.
It can be seen that it is very important for students to understand and master some fire-fighting knowledge to reduce and prevent the occurrence of fires. (1) Playing with Fire Many students are curious about fire and often play games with fire behind their teachers and parents' backs.
Some burn paper and firewood, pile up waste tires and plastics in the wild, some burn matches, match sticks and set off fireworks in the dark, and some burn hornets' nests in the wild. However, almost every game is in danger of causing fire.
Students are young and lack self-protection ability. Please pay attention to: 1. Fully understand the hazards and possible serious consequences of playing with fire, and never play with fire at any time. 2. Lighters, matches, firecrackers, etc. It is often something that induces children to play with fire. Don't carry these things with you at ordinary times.
3. Students should supervise each other and remind each other. If students are found playing with fire, they should stop immediately and report to teachers and parents for criticism and education.
(2) Take good care of the fire-fighting equipment and keep the passage unblocked. In order to prevent major fire accidents and nip in the bud, people have set up fire-fighting equipment in many places. Once these devices are misappropriated or damaged, people will be helpless in case of fire.
1. Do not move, misappropriate or damage fire hydrants, water guns, hoses, fire extinguishers, shovels, picks, hooks, sandboxes, buckets, etc. Modern shopping malls, hotels, libraries and many other public places have installed red fire buttons on the walls. Students should never press them at will.
3. Stair passage is the passage for people to escape from danger in case of fire, and it is also the only way to rescue people trapped in the fire. Be sure to keep it clear. Don't store bicycles or pile up sundries in these places. Third, how to escape the fire mercilessly. In case of fire, students should keep a clear head, race against time and evacuate quickly.
If you are trapped in a fire, you should improvise and try to escape. (1) How to escape from a fire in a bungalow 1. When you are awakened by smoke, you should get out of bed quickly and rush out of the room.
Don't wait to get dressed before you go out. Time is life at this moment. If the whole house is on fire, you'd better climb to the door and find a wet towel to cover your nose and mouth.
Don't go out when the fireworks are closed! You should change other exits and close the doors and windows you pass through to delay the fire from spreading to other rooms. 3. If you are trapped in the house by fireworks, cover your body with blankets or bedding soaked with water, especially wrap your head, cover your nose with a wet towel, and take protective measures before rushing out, the possibility of injury is much less.
Never lie under the bed, under the table or hide in the closet. Don't risk going back to the burning room to save valuables at home.
(2) How to escape from a fire in a teaching building Modern teaching buildings are more difficult to escape in the event of a fire because the floors are gradually increasing, the structure is becoming more and more complex, the density of students is high, and there are more flammable materials such as tables and chairs. Once the building is on fire, you should escape by the following methods: 1. When eureka tower is on fire, don't panic and don't run around. You should calmly find the direction of the fire, determine the wind direction, and leave the fire quickly against the wind before the fire spreads.
2. In case of fire, if the corridor is blocked by fireworks, the door and indoor ventilation holes should be closed immediately to prevent smoke from entering. Then block your nose and mouth with a wet towel to prevent the inhalation of hot smoke and toxic gases, and wet the upward clothes to avoid fire.
If there is only smoke and no fire in the corridor, you can put a large transparent plastic bag on your head to prevent smoke from being inhaled into the respiratory tract and take a low posture to escape from the fireworks area. Never jump from the window.
If the floor is not high, you can use a rope to descend from the window to a safe area under the protection and organization of the teacher. 4. When there is a fire, you can't take the elevator, because the elevator may break down or be burned out at any time; You should run to the ground floor along the fire safety evacuation stairs; If the fire stairs are blocked, you should immediately return to the roof platform and call for help.
You can also break the window glass of the stairwell and shout for help, so that rescuers can know your exact location for rescue. (3) What should I do after the stairs are blocked by fire? Once the stairs are burned out, it seems to have reached a desperate situation, but it is not.
1, you can climb down from the downspout installed next to the window, but pay attention to check whether the pipeline is firm to prevent the human body from breaking and falling off after climbing up, causing casualties. 2. Tear off the sheets, connect them into a rope, tie one end firmly to the window frame, and then slide down the rope.
The flat roof of the building is a relatively safe place, and you can take refuge there temporarily. 4, from the prominent wall, dado and connected balcony and other parts of the transfer to a safe area.
5. Escape to the unlit room and call for help. 6. Jumping off a building is often unlucky and is the most undesirable way to escape.
But if you are trapped on the second floor, you can grab the edge of the window or balcony with your hands, slowly put down your feet and jump off with your knees slightly bent.
3. Fire safety knowledge
Fire control work is a highly knowledgeable, scientific and social work, involving all walks of life and thousands of households, and closely related to economic development, social stability and people's lives.
Only by popularizing fire laws and regulations and knowledge of fire science and technology in the whole society, raising fire awareness and enhancing the ability of prevention and fighting can fire hazards be effectively prevented and reduced. "Fire Safety Knowledge" introduces the basic knowledge and technology of fire safety based on the relevant national fire laws, regulations and rules.
The book is divided into fire hazard, fire prevention, fire fighting, fire escape and fire management * * *, focusing on combustion and explosion, fire hazard classification, fire and explosion prevention principles and measures, fire fighting principles and methods, use of fire extinguishing equipment, use of fire safety facilities, initial fire fighting and emergency response, fire escape methods, basic knowledge of grass-roots fire management, education and training, etc. The book adheres to the principle of integrating theory with practice, pays attention to practicality and operability, adopts the form of question and answer, and is easy to understand.
This book can be used as training materials for legal representatives of enterprises, fire safety managers and key workers, and can also be used for shift workers in enterprises to learn and master fire safety knowledge and skills.
4. Fire safety knowledge
Open a library member at a minimum of 0.27 yuan, and see the full content > Feixiang Graphic 1 What are the contents of the "four abilities" of fire safety? (1) Check the ability to eliminate fire hazards (2) Put out initial fires (3) Organize evacuation and escape (4) Publicity, education and training (2) What is the policy of fire control work? Give priority to prevention, combining prevention with elimination, including fire prevention and extinguishing. 1. "Prevention first" means that when dealing with the relationship between fire prevention and fire fighting, fire prevention must be put in the first place, and various active measures should be taken ideologically, organizationally and institutionally to prevent the occurrence of fire.
2. "Combination of fire prevention and fire extinguishing" means that while actively doing fire prevention work, it is fully prepared for fire extinguishing from the aspects of manpower, material resources and technology. Strengthen the construction of voluntary fire fighting team within the enterprise, equip with sufficient fire fighting equipment, strengthen fire fighting training, do a good job in combat readiness on duty, and make unremitting efforts. Once a fire breaks out, it can be put out quickly and in time to minimize the hidden danger of fire.
3 fire fighting task 1. Control and fire control all unsafe conditions and factors of fire and explosion; 2. Conditions and factors for limiting and eliminating the spread and expansion of fire and explosion; 3. Ensure that there are enough firefighters and fire-fighting equipment to put out the fire in time and reduce losses; 4. Ensure that there are enough safety exits and passages for people to escape and materials to evacuate; 5. Thoroughly find out the cause of the fire and explosion, and achieve "three don't let go" (that is, don't let go if the reason is unknown; Accident responsibility and employees' lack of education; Preventive measures were not implemented. How to use dry powder fire extinguisher? When using portable dry powder fire extinguisher, pull out the safety pin, hold the hose in one hand and aim the nozzle at the root of the flame; Press the handle with the other hand, and the dry powder can be sprayed out to extinguish the fire.
(Note: Pull out the bolt, hold the pipe, and press the handle) When using the fire hydrant, first turn off the power supply at all fire control sites, open the glass door of the fire hydrant, press the manual alarm button, and the connected water pump will automatically pressurize and connect the hose.
5. Fire prevention knowledge
Fire prevention knowledge 1. Fire is a natural phenomenon.
Taming fire is a friend of human beings, which brings light and warmth to human beings and brings human civilization and social progress. However, if the fire gets out of control and leads to a fire, it will cause great losses to people's lives and property.
2. Many students are curious about fire and often play fire games behind their teachers and parents' backs. Some people burn paper and firewood, pile up waste tires and plastics in the wild, light matches, light candles, play with matchsticks and burn wasps' nests in the dark.
But you know that every one of these games may cause a fire. Don't carry lighters, matches, firecrackers, etc.
If students are found playing with fire, they should stop immediately and report to teachers and parents for criticism and education. 4. The Code of Conduct for Primary and Secondary School Students requires students not to smoke.
However, some students violate the regulations and often hide in corners, toilets and other places to secretly smoke. If they suddenly meet teachers or parents, they will throw away cigarette butts or hide them in cuffs and pockets at will. If an unlit cigarette butt meets something, it is easy to cause a fire. There are red fire buttons on the walls of modern shopping malls, hotels and libraries. Students should never press them at will.
Fire hoses, water guns, buckets, fire extinguishers, shovels, picks, hooks, sandboxes, etc. special for fire fighting shall not be moved at will. 6. The TV should keep a certain distance from the wall to facilitate ventilation and heat dissipation.
Don't drive when there is no one indoors. Turn off the machine and unplug it in time after use. 7. Iron clothes with an electric iron. Put the iron on the firebrick, slate and iron bracket.
Don't turn on the power supply when unattended, and unplug it in time after use. 8. The refrigerator should keep a certain distance from the wall and objects on both sides to facilitate ventilation and heat dissipation.
9. Don't bake clothes, towels, etc. Use light bulbs instead of paper as lampshades. If the paper burns and ignites, it will cause a fire. 10 Don't extend or pull the wires of electrical equipment at will.
In particular, do not pull down wires on furniture and carpets to prevent moving furniture or people from stepping on them and causing short circuits and fires. 1 1. When installing cookers, students should remind parents that cookers should be installed at a certain distance from combustible materials such as beds, paper ceilings and wooden window frames. Brick stoves should be used in rural areas, and firewood should be kept away.
12. Don't put waste paper, shavings and other flammable materials near the stove, and there should be a special person to watch over the baking clothes. 13. After completely extinguishing, take out the slag and pour it in a safe place. Pay special attention not to use red fire to pour slag.
14. When starting a fire, don't use gasoline, kerosene and diesel oil to help, in case they burn violently and cause a fire. 15. juniors should not use liquefied petroleum gas.
Senior students should learn some gas stoves and follow the instructions of adults. 16. When cooking with gas, you should concentrate on guarding and adjust the gas quantity at any time to prevent the soup from overflowing and extinguishing the flame, causing air leakage and danger.
17. Liquefied gas tanks should be used upright, away from fire sources, not upside down, and baked with fire. It is forbidden to cross the gas and pour the residual liquid in the tank for other purposes.
Also remind mom and dad to always check whether the rubber tube and switch of liquefied gas stove are in good condition. 18. If liquefied petroleum gas leaks, turn off the fire immediately and check it carefully, and ask mom and dad to take care of themselves or call the gas station staff to repair it.
19. Campus is a place for learning and learning, with many people and concentration, especially in primary schools. Students are young and have poor self-protection ability. Once a fire breaks out, it will inevitably cause serious consequences. Therefore, we should pay special attention not to bring matches, lighters, firecrackers and other kindling into the campus to prevent campus fires. 20. Some chemicals used in the experimental class are flammable, so the operation must be done according to the teacher's requirements.
Don't make drugs at will, which violates the operating rules. 2 1. During the cleaning, some schools used to pile up and burn leaves and garbage, which not only polluted the environment, but also easily caused fires.
It is sanitary and safe to treat garbage by deep burial, which is worth learning and popularizing. 22. Don't bring matches, lighters, etc. When going out for activities, don't carry any inflammable and explosive articles.
Generally, we don't organize picnics when we go out. It is really necessary. Be sure to choose a seaside or an empty and safe place under the guidance of a teacher or counselor. It should also be noted that picnics should stop in windy weather.
After the picnic, be sure to put out the fire to prevent the "resurgence" from causing forest fires. 24. accompany your parents to the grave, don't burn incense and paper.
Grave-sweeping and offering a bunch of flowers can also pin our grief for our loved ones. In case of fire, students must keep calm and try their best.
At the beginning of a fire, it is usually a small fire point, with a small burning area and less heat generated. At this time, just cover it with sand, dry soil, soaked towels, cotton, sacks, etc. , can put out the initial fire.
26. If the fire is fierce, spreading or likely to spread, don't try to put out the fire. You should escape from the fire immediately and call 1 19 to put out the fire through the fire brigade. When giving an alarm, specify the fire unit, district (county), street, alley, house number or rural address.
Explain what caught fire and how it was burned. Find out the name, telephone number and address of the policeman.
27. After the alarm, arrange people to wait for the fire truck at the intersection and guide the fire truck to the fire section. 28. Some students like to watch fire engines out of curiosity, which is not only harmful to the work of firefighters, but also harmful to the safety of students.
29. Don't call the fire alarm at will. Misreporting a fire alarm is an illegal act that disturbs public order and hinders public safety.
Someone is found lying about the fire alarm, so stop it. 30. In order to protect the legitimate rights and interests and life safety of young people, the state explicitly prohibits schools, government agencies and other social organizations from organizing primary and secondary school students to participate in fire fighting.
6. Fire safety knowledge: how to prevent fire?
First of all, the way to avoid fire.
1, pay attention to the safety of electricity use, and it is forbidden to pull the wires indiscriminately, and pay attention to the aging and damage of the wires.
2. Try to avoid using open flame lighting such as candles and kerosene lamps, and try to use charging equipment such as flashlights for lighting.
3, indoor smoking, pay attention to safety, completely put out the fire after smoking.
It is best to unplug the unused electrical appliances, which not only cuts off the fire hazard, but also saves electricity.
5. Check whether the fire escape in the area is clear, and notify the electrician to handle it when the lighting power supply fails.
6. Check whether the fire exits, fire hydrants and shutter doors in the area are blocked by commodity sundries, whether the fire extinguishers are in place, and handle any abnormal situations in time.
Second, the fire treatment method
1. In case of fire, be sure to keep calm. Call the fire alarm number, calmly answer the questions of the police on duty, explain the exact location of the fire, the name of the unit, the street where it is located, the house number, the location of the fire, the burning substance and the size of the fire, and leave the name and contact number of the alarm person. If it is in a remote place, send someone to meet the fire truck at the intersection.
2. Squat down or lie down immediately, move or crawl away along the direction indicated by the exit light, and cover your nose with a wet towel to prevent suffocation by inhaling smoke. Don't take the elevator in case of fire.
3. See if there are fire-fighting equipment, such as fire extinguishers, at the scene of the fire, which can be put out properly to help escape.
4. When people are trapped in the fire escape, they should evacuate in an orderly manner and pay attention to the escape route. They can't take the elevator, but should take the fire escape.
7. Do you know anything about fire safety?
Do you know anything about fire safety? First, what should I pay attention to in fire prevention? There are many measures to prevent fire. Start with the little things in daily life: 1, don't play with fire.
2. Take care of fire control facilities. In order to prevent fire and fire accidents, fire hydrants, fire extinguishers, fire sandboxes and other fire-fighting facilities have been set up in residential buildings and public places, and safe passages for evacuation have been left in case of fire. We should consciously care for fire control facilities and ensure the smooth passage of safety.
Second, how to pay attention to fire prevention at home? Fires at home are often caused by careless use of fire and improper use of electrical appliances. Attention, students: 1 The use of household appliances should meet the safety requirements, and do not disassemble them at will, so as to avoid the decline of safety performance and fire. 2. Be careful when using hot appliances (such as electric irons), and don't make them ignite flammable items.
3. When electrical appliances are used or personnel leave, turn off the power supply in time to prevent electrical appliances from overheating. 4. Use gas appliances to prevent gas leakage, and turn off the gas source after use. 3. How to pay attention to fire prevention in school? There are also fire safety problems in schools, so the following points should be noted: 1, do not bring matches, lighters and other kindling into the campus, and do not bring inflammable and explosive articles such as gasoline and firecrackers into the campus.
2. When the experimental class needs to use alcohol lamps and some flammable chemicals, it should be carried out under the guidance of the teacher and in strict accordance with the operating requirements. Be careful to prevent the danger of using fire.
8. Safety and fire prevention knowledge
1. Safe production refers to efforts to improve working conditions, overcome unsafe factors, prevent casualties and ensure the smooth progress of labor production on the premise of ensuring the safety and health of workers and the safety of life and property of the country and people.
This definition covers three issues. Namely, goal, scope and purpose.
The object of safe production is all unsafe factors such as people and equipment, among which people are the first. Eliminate all unfavorable factors that endanger personal health, ensure the safety and health of employees and work comfortably. This is called personal safety. Eliminating all dangerous factors that damage equipment, products and other property and ensuring normal production is called equipment safety.
Safety in production covers a wide range, including industries such as industry, commerce, transportation, transportation, agriculture and forestry. The purpose of safe production is to ensure the safety and health of workers and the safety of state property and people's property.
Safety management: a series of activities carried out to do a good job in safety production are called safety production management (including system, education, inspection, supervision, publicity and punishment, etc.). ) .2. The "Twelve-character Policy" for Safety in Production: Safety first, prevention first and comprehensive management "Safety first" are the basic principles that enterprises follow in production.
B "prevention first" is the basis and premise of implementing "safety first". "Comprehensive management" is a measure and means.
3, the four principles of production safety management. (1), adhere to the principle that production must be safe. Safety exists in production and plays a role in promoting and ensuring production.
Therefore, although there are sometimes contradictions between safety and production, the goals and objectives of safety and production management show a high degree of consistency and complete unity. "Managing production must manage safety" is not only to clarify the safety management responsibilities of leaders at all levels, but also to clarify the safety management responsibilities of all production-related institutions and personnel within their business scope.
It can be seen that all institutions and personnel related to production must participate in safety management and take responsibility in management. It is a one-sided mistake to think that safety management is only a matter for the security department.
(2) Adhere to the principle that safety has the right to deny; (3) Adhere to the principle of "three simultaneities". This principle means that all productive capital construction and technical transformation projects must comply with national occupational safety and health regulations and standards, and occupational safety and health technical measures and facilities should be designed, constructed and put into use simultaneously with the main project. (4), adhere to the principle of "four don't let go" means that when investigating and handling industrial accidents, we must adhere to the unclear analysis of the cause of the accident; Those responsible for the accident and the masses were not educated; Failing to take feasible preventive measures; The person responsible for the accident has not been dealt with seriously.
4. National production safety management system China's current safety management system is "* * * unified leadership, supervision by departments according to law, overall responsibility of enterprises, and social supervision and support." * * * Unified leadership: refers to putting forward unified requirements for work safety under the leadership of the State Council and local people at all levels and in accordance with national laws and regulations on work safety.
Department supervision according to law: refers to the safety production supervision department and relevant departments, which perform comprehensive supervision and management and supervision and management duties in a certain aspect according to law. The overall responsibility of the enterprise: First, the main person in charge of the enterprise is fully responsible for the safety production of the enterprise and fully implements the responsibility system for safety production, which is the need of the national economic system reform and the inevitable result of decentralization and expansion of enterprise management since * * * *. Therefore, the new safety production management system highlights the responsibility of enterprises.
Social supervision and support: give full play to the role of all aspects of the whole society, and form a public opinion atmosphere of caring for life and managing exclusive rights in the whole society. 5. What is an accident? (1) In a broad sense, an accident refers to an unexpected event that occurs suddenly, goes against people's will and cannot be foreseen in advance due to unsafe behavior, action or unsafe state in the process of realizing purposeful behavior. It will cause property damage, production interruption and casualties.
(2) From the perspective of labor protection, accidents mainly refer to casualty accidents, also known as work-related injuries. 6. Four characteristics of the accident (1) Causality: the result of interaction of many interrelated factors.
(2) Randomness: The time, place and consequences of the accident are accidental. (3) Latency: If there are trigger conditions, the accident may happen suddenly.
(4) Preventability: Accidents can be prevented as long as correct preventive measures are taken. 7. Accident classification (1) According to the degree of injury: minor injury, serious injury and death.
(2) According to the severity of the accident: minor injury, serious injury, death, major casualty accident, major casualty accident. (3) According to accident types, it can be divided into: object strike, vehicle injury, mechanical injury, lifting injury, electric shock, weak water permeability, combustion, fire, falling from a height, collapse, roof caving, water permeability, shooting, gas explosion, gunpowder explosion, boiler explosion, container accident, other explosion, poisoning suffocation and other injuries.
8. Analysis of Unsafe Factors in Accidents Unsafe factors in accidents mainly include unsafe behaviors of people, unsafe state of things and management defects: (1) Unsafe behaviors of people "people" exist objectively in production and are also decisive factors related to safety. Many problems in production are solved by human operation, which is easy to lead to accidents due to inattention, lack of experience, weak sense of responsibility, ignorance and bad mood.
(2) Unsafe state of things Products, raw materials, intermediates, water, electricity, factories and construction sites in production all belong to "things". The unsafe state of "things" leads to accidents. For example, chemical poisons (H2SO4 and NH3) can cause burns and explosions, high-temperature and high-pressure containers can cause explosions, electricity can cause electric shock accidents, and buildings cut corners.
(3) Management defects Nothing can have a perfect safety concept and design, limited cognitive ability, limited technical conditions and traffic accidents. It is impossible to set up automatic alarms and build bridges at every intersection, sidewalk and railway intersection. 9. Accident Pyramid: Behind the death and serious injury accidents of 1, there are 29 minor injuries, behind the 29 minor injuries, there are 300 harmless false positives, and there are a lot of unsafe behaviors and unsafe conditions.
