With the continuous improvement of living standards, there are more and more places to use electricity in life. Therefore, it is necessary to master the following basic common sense of safe electricity use: l. Know the main switch of power supply and learn to turn off the main power supply in an emergency. 2. Touch and test the inside of the power socket without hands or conductive objects (such as wires, nails, pins and other metal products). 3. Touch the appliance with wet hands and wipe it with a wet cloth. Do not pull the wire forcibly when plugging and unplugging the power plug to prevent the insulation layer of the wire from being damaged and causing electric shock; The insulation of the wire falls off, so it is necessary to replace the new wire or wrap it with insulating tape in time. 5. When someone gets an electric shock, 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 appeal to adults for help, and don't handle it by themselves to prevent electric shock. 6. Don't disassemble the power cord, socket and plug at will. Even if it is as simple as installing a light bulb, you should turn off the power first and finish it under the guidance of your parents. Nowadays, more and more household appliances, such as televisions, refrigerators, washing machines, electric irons, hair dryers and electric fans, are used at home. Besides paying attention to the safe use of electricity, we should also pay attention to the following points: 1. Various household appliances have different uses and methods of use, and some of them are more complicated. General household appliances should be studied and used under the guidance of parents, and those with greater risks should not be used by themselves. 2. If there is the smell of smoke, sparks and burning, immediately turn off the power switch and stop using it. At the same time, pay attention to avoid burns when using. 4. Avoid using electrical appliances in humid environment (such as toilet), and don't let electrical appliances get wet, which will not only damage electrical appliances, but also cause electric shock. 5. The fan blades of the electric fan and the dehydration cylinder of the washing machine are rotating at high speed when working, so you can't touch them with your hands or other objects to avoid injury. 6. Stop using TV in thunderstorm weather. Prevent being struck by lightning. 7. If the electric appliance is not used for a long time, it is easy to be damaged by moisture and corrosion, so it needs to be carefully checked before reuse. 8. When purchasing household appliances, you should choose qualified products with reliable quality.

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.

4. Common sense of safe electricity use in office buildings in summer (2000 words)

In hot, humid and rainy summer, we should pay attention to the safety of electricity consumption at home. The following matters should be paid attention to in the common sense of home safe electricity use in summer: 1. Don't buy fake and shoddy "three noes" household products. In family life, if electrical equipment, lamps and other electrical appliances need to be installed, they should be installed by qualified electricians. In the process of use, when electrical equipment fails, it should be repaired by qualified electricians. 2. Consciously observe the safe use. It is forbidden to pull wires and install electric furnaces privately. When repairing household appliances, you must first disconnect the power supply. Third, when using household appliances, there should be a complete and reliable power cord plug. All household appliances with metal shells should be protected by grounding. The electric light line should not be too long, and the lamp holder should not be less than 2 meters from the ground. The lamp holder should be fixed in one place to avoid electric shock. Four, air conditioning, electric fans, refrigerators and other electrical equipment with metal shell, should be grounded in accordance with the provisions. The installation and maintenance of grounding wire should be carried out by electrician. Don't touch live equipment with wet hands, and don't wipe live equipment with wet cloth. 5. Choose the fuse according to the wattage of the electrical equipment, and don't change the specification of the fuse without authorization because of the high power consumption in summer. If the fuse is blown frequently, a qualified electrician should find out the reason and eliminate the fault. 6. Don't pull the wires around. Don't touch live equipment casually. Switches and fuses can be installed on the ground wire and neutral wire. It is forbidden to connect the ground wire to the tap water and gas pipeline. 7. When the power cord of household appliances is damaged, it should be replaced immediately or wrapped with insulating cloth. When moving electrical equipment, you must turn off the switch first, and then move the equipment. It is not allowed to move with electricity. After the electrical equipment with metal shell such as motor is moved to a new location, the grounding wire should be installed first, and the equipment should be inspected to confirm the equipment.
