2. What is the common sense of preventing electricity?
With the continuous improvement of living standards, there are more and more places to use electricity in life. Therefore, it is necessary for us to master the following basic knowledge of safe use of electricity:
L know the main switch of power supply and learn to turn it off in an emergency.
2. Do not touch or test the inside of the power socket with your hands or conductive objects (such as wire, nails, pins and other metal products).
3. Don't touch the appliance with wet hands or wipe it with wet cloth.
4. Unplug the electrical appliance after use; Don't pull the wire when plugging and unplugging the power plug to prevent the insulation of the wire from being damaged and causing electric shock; The insulation layer of the wire is peeling off, so it is necessary to replace the wire in time or wrap it with insulating tape.
5. Find someone get an electric shock to try to turn off the power in time; Or use dry wooden sticks and other things to separate the electric shock victim from the charged electrical appliances, and don't save people directly by hand; Younger students should ask adults for help in this situation, and don't handle it by themselves to prevent electric shock.
6. Don't disassemble or install the power cord, socket and plug at will. Even if it is as simple as installing a light bulb, it should be turned off first and carried out under the guidance of parents.

5. Anti-electricity safety knowledge
How to prevent the harm of lightning
In nature, lightning and thunder often appear. Lightning does great harm to people's lives, and mastering the correct lightning protection methods can reduce the occurrence of personal injury and death accidents.
Living in a thunderstorm season or place, always pay attention to the weather forecast on TV or radio. In order to avoid lightning accidents, you should pay attention to arranging mountain climbing plans or other outdoor activities according to weather changes.
When encountering thunderstorm weather in the wild, try not to walk in the rain, especially not to ride a bike or ride a horse. During a thunderstorm, all metal objects (such as knives, umbrellas, watches, glasses, cameras, iron farm tools, etc. ) It should be thrown away. In the wild, try to squat down a little; People who swim or take a boat in the water should go ashore as soon as possible to avoid the rain.
Take shelter from the rain during a thunderstorm, don't hide under trees or telephone poles, and don't stand by and watch the walls of tall buildings. It's safer to crouch in the tree Takaso as far as possible. It should be noted that the plant shed or pile in the field is easy to be the target of lightning strike.
During a thunderstorm, even if people are indoors, they will be struck by lightning if they don't pay attention to lightning protection. Because lightning may invade the room from open doors, windows, flues, etc. Close the doors and windows in time when it rains, stop using the TV with outdoor antenna, and unplug other household appliances when the thunderstorm is dense. It is safest for people to stay in the middle of the room at home, but avoid staying directly under the electric light. Don't lean against posts or walls, and don't touch doors, windows and all metal devices along the walls to avoid electric shock accidents when it thunders.
When someone is struck by lightning in rainy days, they should be rescued immediately. Those who have lost consciousness should be given artificial respiration and chest compressions, and those with skin burns should be treated with burns. Severe burns should not be coated with oil and ointment to avoid blisters and infection.

7. 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 at the same time as 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.
