With the progress of the new era, electricity is a necessity of people's life now, and our production and life are inseparable from electricity everywhere. If we don't pay attention to the safety of electricity use in the process of electricity use, it may affect the safe operation of power system and even cause personal electric shock casualties. Moreover, we use electricity all the time in the university, such as dormitory electricity and laboratory electricity. If you don't pay attention to it, it may cause harm to people and together.

The school dormitory is the place where our students live and stay for the longest time. However, students' awareness of electricity prevention is weak when using electricity in the dormitory, such as using electrical appliances exceeding the maximum voltage in the dormitory and connecting wires in the dormitory, which may cause dangerous accidents in electricity use. Therefore, when we use electricity in the dormitory, we must first understand the safety knowledge of electricity consumption in the dormitory, and understand the main switch of power supply, line layout, power limit load and so on. It is forbidden to touch or probe the inside of the power socket with hands or conductive objects; Unplug the power plug correctly after the power supply is used up, and do not pull the wire to protect the insulation layer; When there is no one in the dormitory, all power supplies must be cut off, so that "the lights go out when people walk, and the electricity goes out when people walk"; It is forbidden to change, disassemble and install power cords, sockets and plugs in the dormitory. Do not chisel nails and other hard objects into the wall to prevent accidents such as short circuit and electric shock. In the process of use, if you find a charger, desk lamp, etc. When there is the smell of smoke, sparks and burning, immediately turn off the power switch and stop using it; When the common electrical equipment in dormitory breaks down, it should be reported to the relevant departments for maintenance according to the procedure. Self-provided electrical equipment should be maintained by professionals in case of power failure, and unauthorized operation is strictly prohibited.

The laboratory is mainly the place where students learn experimental operations and complete scientific research results. The experimental instruments in it are very expensive. If there is an electric shock accident in the laboratory, it will endanger personal safety, damage instruments and equipment, and even cause an explosion or fire. Therefore, we should also pay attention to the safety of laboratory electricity. When we are in the laboratory, we should prevent electric shock accidents. First of all, we should always check the wires, sockets and plugs, and replace them immediately if they are damaged. Don't use high-power electrical appliances at will. If you have special needs, you must contact the school and use special wires. Be familiar with the operating procedures of instruments and equipment before starting, and then turn on the power supply after confirming that it is in good condition.

Now electricity has spread to all parts of the country, although it is all in safe voltage, but the safety of electricity use is still a big hidden danger, so we should take a "nip in the bud" attitude towards electricity use. As college students, we should lead by example, use electricity safely in life and study, and provide more protection for ourselves and our loved ones.
