2. Give priority to the protection of power facilities, the common sense of safe electricity use, and the relationship between electricity use and life. Write one.
I found what you said and a composition for you alone. But you need to sum it up yourself. There are many things that are very scattered. (Be sure to choose me and give me points. (Protect power facilities) (Choose a few yourself. Electric energy is the most basic energy in modern society, and people can't live without it almost all the time. It all depends on it. It is the unshirkable responsibility and obligation of every citizen to protect the safety of power facilities. 1. Pay attention to the safe distance between overhead high-voltage lines and ground attachments. Overhead high-voltage lines will form a dangerous area under them because of their drooping weight and cheap wind. Trees in this area should not be too high, miscellaneous trees must be removed, and buildings that may endanger power facilities should not be built. Safety measures must be taken when vehicles with a height of more than 4m pass under high-voltage lines. 2. Pay attention to the safety range of underground cables. There are obvious signs of cable wells and piles on the surface of underground cables in cities. The width of the underground cable protection zone is 0.75m on both sides of the ground pile. It is forbidden to construct and plant trees in this area, and it is not allowed to pile up sundries or dump harmful chemicals. 3. Ensure the safety of high-voltage lines during construction. When working near the high-voltage line, ensure the safe distance between the tower crane and the high-voltage line to avoid the rotating boom touching or damaging the high-voltage line. 4. It is forbidden to connect non-power lines to high-voltage lines. Telephone lines and communication lines should be erected independently. Do not connect electrical equipment directly to power facilities without authorization. 5. Before planning the road, consider whether there are high-voltage poles in the planning area. When it is determined that it is inevitable, work out a feasible plan with the power supply department. 6. Don't fish under high voltage lines. Don't fly kites and throw objects within 300 meters near high-voltage lines. Don't shoot birds at the wires. Prevent the plastic cloth and other sundries in the vegetable greenhouse from scratching the wires. 7 signs for the protection of power facilities, and their signs and pole numbers shall not be covered by advertisements or paints. 8. Don't climb transmission line towers and transformer racks at will, and stay away in rainy days to prevent electric shock or lightning strike. 9. Pay attention to protect the tower foundation and stay cables of overhead power lines. It is forbidden to dig, pile up, drill or dump corrosive chemicals within the planning scope of the outer edge of the foundation. The planning scope of the outer edge of the power tower and cable foundation below 35kV is 5m, and the planning scope of the power tower and cable foundation above 66kV10m is10m. * * * Cooperate with the supervision and severely crack down on illegal acts of cutting and stealing power facilities. Adhere to the idea of "safety first, prevention first", ensure the safety of life and property, truly attach importance to safety from the heart and promote safe production. 2. Be familiar with the location of air switch (commonly known as master brake) in your production site or dormitory (such as toll plaza, construction site, office, dormitory, etc.). ), and cut off the power supply as soon as possible to prevent fire, electric shock or other electrical accidents. Avoid causing greater property losses and personal injuries. 3. Do not connect wires without permission, do not hang clothes and sundries on wires or other electrical equipment, and do not install and use high-power or electrical equipment that does not meet national safety standards without permission. If necessary, apply to the relevant departments for approval, and be installed by electricians. 4. Do not disassemble electrical equipment such as lamps, switches and sockets without permission, and do not use lamps to bake clothes or use them for other purposes. When there are abnormal phenomena such as smoke, arcing and burning smell inside the equipment, the power supply of the equipment should be cut off immediately and the electrician should be notified to carry out maintenance to avoid expanding the fault range and electric shock accidents; When the leakage protector (commonly known as leakage switch) trips, it is not allowed to reclose without permission. 5. When using electrical equipment (such as hair dryer) in the bathroom or in a place with high humidity, ensure good indoor ventilation to avoid electric shock accidents due to poor insulation of electrical equipment. 6. Ensure good heat dissipation of electrical equipment (such as televisions, electric water heaters, computers, stereos, etc.). ), inflammable and explosive articles and sundries are not allowed to be piled up around. 7. Cherish the power resources and form a good habit of using electricity safely and economically. When leaving or not using for a long time, it is necessary to ensure that the power supply (especially electric heating appliances) is cut off before leaving. 8. Electrical appliances and electrical equipment with mechanical transmission must be protected by protective covers, shields or fences, and hands or bodies cannot be put into the mechanical transmission position of running equipment. When cleaning the equipment, it must be carried out under the condition of cutting off the power supply and stopping the machinery to ensure safety, so as to prevent personal injury. 9. Don't climb high-voltage towers, fly kites or engage in other activities near high-voltage lines. 10. Do not enter the electrical room or electrical construction site without the permission of relevant departments. By letting our students watch DVD, we have a deeper understanding of how to use electricity safely and protect power facilities, increase our knowledge of safe use of electricity and awareness of electricity prevention, and play a positive role in reducing and preventing the occurrence of electricity safety accidents. It also makes us realize that every student should learn from an early age, start with me and use electricity safely. In electrical science, everyone strives to be a "safety propagandist". ┃ Example composition ┃ Electricity-this word must be familiar in everyone's dictionary. With the rapid development of the times and the progress of human civilization, the importance of electricity has become increasingly prominent. Nowadays, high technology affects our lives everywhere: it becomes more convenient and colorful. But most of these high-tech products need electricity, so-electricity. With electricity, people can see Xiao Liang in the dark; With electricity, people can enjoy more fun and happiness in life, can't they? When you are comfortably enjoying the electric water heater in the bathroom, when you are happily staring at the TV screen, when you are enjoying entertainment and work at the computer desk, the electric partner silently gives them the power of "life". Electricity is a kind of fast supply and environmental protection energy. Electricity has brought us too many benefits. Imagine if there were no electricity in this developed society. What a troublesome thing this will be. 2008 should be an auspicious year for the Olympic Games. At the beginning of the new year, God played a huge joke on people. When people look at the sky, they don't feel anything unusual.
3. Common sense of safe electricity use
Tips for safe use of electricity 1. The insulation of the power cord and electrical equipment must be good, and the live parts such as lamp holders, sockets and switches must never be exposed to prevent electric shock.
2, don't pull the wire, to prevent electric shock or fire. 3, don't stand on the wet ground to move charged objects or try to clean charged household appliances with a wet rag to prevent electric shock.
4, fuse selection should be reasonable, avoid using copper wire, aluminum wire or iron wire instead, in case of fire. 5, the use of household appliances such as refrigerators, freezers, washing machines, etc. , should be equipped with grounding wire socket according to the requirements of product use.
6. When repairing or replacing the lamp holder, even if the switch is turned off, do not touch it directly by hand to prevent electric shock. 7, in case of electrical fire, to cut off the power supply for rescue, avoid by all means directly put out with water, in order to prevent electric shock.
8, found that someone get an electric shock, should try to disconnect the power supply (such as electric shock in high places, also want to take measures to prevent electric shock fall injury) and then first aid. ~ If you agree with my answer, please click the "Accept as Satisfied Answer" button in time ~ ~ The mobile phone questioner can evaluate the satisfaction in the upper right corner of the client.

4. Some common sense of household electricity use
L know the main switch of power supply and learn to turn it off in an emergency.
First of all, you should know something about the main power switch in the dormitory. How many students know the location of the main power switch in the dormitory? 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; Especially electrical appliances with transformers (such as audio, power amplifier, repeater, mobile phone charger, computer, etc. ), the primary coil of the transformer is usually directly connected to the power plug. When we turn off the power switch of the electrical appliance, we can't cut off the connection between the primary coil and the power supply. If it takes a long time, it will lead to overheating of the transformer and aging of the insulation layer, which will affect the service life of the electrical appliance. In severe cases, the electrical appliance will catch fire and cause a fire.
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 a dry wooden stick to separate the electric shock victim from the charged electrical appliance, and don't save people directly by hand.
6. Do not remove and install the power cord, socket, plug, etc. Feel free, and don't pull the wire without permission. The main power switch of the dormitory has the functions of leakage protection and overload protection. We pull wires from the corridor to the dormitory privately. Because the lighting switch in the corridor is not equipped with such leakage protection switch, it is easy to cause electric shock accidents.
In addition, the lines in the corridor are designed according to the power of the lighting bulbs. If high-power electrical appliances are used to pull wires privately, it is easy to make the transmission lines heat up or even catch fire.
5. Who has the common sense of using electricity safely?
When household appliances catch fire: calm down first, don't panic, call the fire alarm number: 1 19, and remember to calm down. Panic can only be counterproductive.
Cut off the power first, and then put out the open flame. Generally speaking, dry fire extinguishers or carbon dioxide fire extinguishers are used when charging. But ordinary families don't.
I feel that it is better to cover it with a quilt after cutting off the power supply in a small-scale electrical fire. As we all know, cotton (duck down quilt, nylon, etc. Are not allowed, and it is not easy to produce open flames, so you can find them at home. After covering, the open flame of electrical appliances will naturally go out without oxygen. Large-scale electrical fire, life first. People should evacuate as soon as possible. Don't neglect life because of property. With life, we can start all over again.
Never pour an open flame with water or other liquids, because water also conducts electricity. If you have time, you can do a detailed search on the internet to prevent problems before they happen.
Electric shock first aid: When the electric shock victim leaves the power supply, the on-site rescue work should be organized quickly according to the specific situation of the electric shock victim. The nursing and rescue methods should be determined according to the physical condition of the electric shock victim.
People may not die immediately after getting an electric shock, but also have symptoms such as nerve paralysis, respiratory interruption and cardiac arrest. They seem to be in a coma. At this time, they should be considered as suspended animation. If the on-site rescue is timely and proper, people can be rescued. On-site first aid is very important for rescuing people who get an electric shock.
According to some foreign statistics, 90% of people who start treatment 1 min after electric shock have a good effect; People who start treatment within 12 minutes after electric shock are unlikely to save their lives. Thus, the rescue time is an important factor.
Therefore, it is very important to race against time and rescue in time. At ordinary times, employees should be educated about the common sense of electric shock first aid, and the relevant personnel of electrical equipment should also be trained in electric shock first aid.
Coma rescue after electric shock generally takes a long time and must be carried out patiently. Only when the victim's face improved, his lips flushed, his pupils narrowed and his heartbeat and breathing gradually returned to normal, could he pause for a few seconds to observe.
If the person who gets an electric shock cannot maintain normal heartbeat and breathing, he must continue to be rescued. The first aid of electric shock should be carried out on the spot as far as possible. Only when the conditions do not allow, can the electric shock victim be carried to a reliable place for first aid.
On the way to the hospital, the rescue work can't stop until the doctor announces that it can stop. Don't inject cardiotonic needle easily during rescue, and use it only when you are sure that your heart has stopped beating.
First, the rescue method (1) The person who got an electric shock was conscious, but some people were flustered, numb limbs, general weakness or the person who got an electric shock was once in a coma during the electric shock, but has recovered. People who get an electric shock should rest quietly, don't move around, observe closely, and send them to hospital for treatment if necessary.
(2) The electric shock victim has lost consciousness, but his heart is still beating and breathing. People who get an electric shock should lie comfortably and quietly in fresh air, unbuttoning buttons and belts that hinder breathing. If the weather is cold, keep your body temperature and call the doctor to the scene quickly.
(3) If the electric shock victim loses consciousness and stops breathing, but his heart is still beating, mouth-to-mouth (nose) artificial respiration should be carried out immediately, and a doctor should be called to the scene in time. (4) If the breathing and heartbeat of the electric shock person completely stop, mouth-to-mouth (nose) artificial respiration and chest compressions should be carried out immediately, and a doctor should be called to the scene quickly.
It should be noted that even on the way to the hospital, first aid should be given as soon as possible. Ii. Precautions in the rescue process (1) Before artificial respiration and first aid, the buttons, ties and belts of the person who gets an electric shock should be quickly untied, dentures, foreign bodies and mucus in the mouth should be removed, and the respiratory tract should be kept clear.
(2) Don't let the person who gets an electric shock directly lie on the wet or cold ground for first aid. (3) Artificial respiration and first aid should be carried out continuously, and the rhythm should be consistent when changing people.
If the spontaneous breathing of the electrocuted person is weak, artificial respiration should be continued, but it should be consistent with the spontaneous breathing rhythm of the electrocuted person until the breathing is normal. (4) insist on rescuing those who get an electric shock.
If the pupil is dilated, the body is stiff, and lividity appears, the doctor must diagnose and confirm the death before stopping the rescue. Third, cardiopulmonary resuscitation method Once the electric shock person has symptoms of sudden stop of breathing and heartbeat, he must immediately give CPR first aid.
Cardiopulmonary resuscitation (CPR) is a systematic emergency rescue method, which mainly includes airway unblocked, mouth-to-mouth artificial respiration, chest compressions and the prevention of complications after the injured person's heartbeat and breathing suddenly stop due to various reasons (such as electric shock). 1. Method for judging respiration and heartbeat. If the electric shock victim loses consciousness, the ambulance personnel should judge the breathing and heartbeat of the injured person in the shortest time.
The method is: see if the chest and abdomen of the electric shock person have ups and downs; Listen to whether there is breathing sound at the mouth and nose of the electric shock victim; Test whether there is expiratory airflow at the mouth and nose by hand, or test whether the carotid artery in the depression next to the Adam's apple beats by finger. If there is neither breathing nor neck pulse, it can be judged that the person who has been electrocuted has stopped breathing and heartbeat.
2. The airway is unobstructed. Anyone who gets an electric shock unconsciously may block the breathing population to varying degrees due to the retraction and descent of the tongue base, making it difficult or impossible for air to enter the lungs, as shown in Figure 5- 1. At this time, the airway should be opened immediately. If there is a foreign body in the mouth of the electric shock victim, it must be taken out first, and attention should be paid to prevent the foreign body from being pushed deep into the throat during operation.
Fig. 5- 1 airway condition "chin-lifting method" is used to make the airway smooth, and the specific steps are as follows: the rescuer puts one hand on the forehead of the electrocuted person, and raises the jaw with the other hand, so that his head leans back, the base of his tongue is raised, and the airway is smooth. As shown in Figure 5-2.
Caution: Do not put pillows or other objects under the head of the person who gets an electric shock. When the head is lifted forward, the airway obstruction will increase, and when the chest is pressed, the blood flow to the brain will decrease or even disappear. 3. People who get an electric shock by mouth-to-mouth (nose) artificial respiration lie on their backs. You can put something under your shoulders to make your head lean back as far as possible and your nostrils face up.
On the left or right side of the electrocuted person's head, the rescuer tightly covers his nostrils with one hand and opens his mouth with the other (if he can't open his mouth, he can point his mouth at his nose, but cover his mouth at this time to prevent air leakage). After inhaling deeply, he will blow tightly into his mouth, expanding his chest when blowing, and then quickly remove his head to let the electrocuted person exhaust himself. Children can only breathe with a small mouth and need to lift it on the chest corridor.
As shown in figure 5-3. Rescue one.
6. Tell me about the safe use of electricity.
It's Brother Dayong. O(∩_∩)O~ First of all, the fuse of the brake box must be suitable. If it is too thick, it will easily cause a fire. If it is too thin, there will always be power failure! Second: when it thunders, be sure to turn off the TV, computer, wireless phone, etc. , otherwise it is easy to be struck by lightning! Third: high-power electrical appliances must be grounded to prevent CLP! Do not touch high-voltage charged objects, do not approach high-voltage charged objects, and do not touch the switch with wet hands. People's safe voltage is not higher than 36 volts. Use an electric pen, a metal bar that can't touch the nib. High-power electrical appliances must be grounded, and neither live wire nor ground wire can be connected with the body. The total power of the electrical appliances used should not be too high, otherwise it will cause a fire due to excessive current. Someone got an electric shock and couldn't pull his body. Turn off the main switch immediately, and then separate the person from the wire.
7. Power safety knowledge
At least 0.27 yuan to open a library member, check the complete content > three years and five years 158 common sense of electricity safety 1. Basic knowledge current: Under the action of electric field force, the charge moves regularly to form current, which is equal to the amount of electricity passing through the conductor section in unit time, also known as current intensity.
Voltage: Voltage is the potential difference between two points in an electric field or circuit, and the basic unit of voltage is volt. Direct current: when current flows in a conductor, its magnitude and direction do not change with time, which is called direct current.
AC: AC is generally divided into single-phase AC and three-phase AC. The direction and magnitude of the current and voltage of alternating current change periodically according to certain rules, and the number of times it alternates per minute is called frequency.
The frequency of alternating current usually used in China is 50 Hz. Short circuit: the current flows through the conductor and the electrical load, and then returns to the power supply, forming a closed loop.
If two wires touch each other in a circuit with current flowing, or when two wires are connected by other objects with low resistance, a short circuit is formed. Low-voltage electricity and high-voltage electricity: Generally, the voltage to the ground is 250V to divide the high and low voltages of alternating current.
Any equipment with a ground voltage greater than 250V is called high voltage, such as 10KV and 35KV. Where the voltage to the ground is below 250V, it is called low-voltage electricity, such as 220 V.
Safe voltage: A voltage series provided by a specific power supply to prevent electric shock accidents. The upper limit value of this voltage series should not exceed the effective value of alternating current (50-50-500 Hz, 50V) between two conductors or between any conductor and ground under any circumstances.
(* The "safe ultra-low voltage" that allows continuous contact under general environmental conditions is 24V. The rating of safe voltage is 42, 36, 24, 12, 6V.
When the electrical equipment adopts the resistance that exceeds the human body as seen from the table, the height should be less than 323131333532363134313635438+03635333e 78988e69d831.
