What are the safety problems in household electricity use?

precautions for safe power use

(1) do not pull wires and connect electrical equipment randomly, and do not use the "one wire one ground" mode to connect electricity.

(2) do not fly kites, fight birds, install antennas near the electric wire, or tie livestock on the pole and stay wire, or dig pits or take soil near the pole and stay wire to prevent broken wires.

(3) do not repair electrical equipment with electricity, causing electric shock.

(4) do not dry clothes on the wire to prevent electric shock caused by insulation damage and leakage.

(5) do not close to the ground when the wire breaks. For example, the 10kV high-voltage wire should be at least 8-10m away from the ground point of the wire, and timely report to the relevant department for repair.

(6) do not touch the light port, switch and socket with wet hands. When changing the bulb, first turn off the switch, and then stand on the dry insulation. Don't pull the light cord too long or around.

(7) in case of electric shock, the power supply shall be cut off immediately or the wires shall be separated with dry wood sticks, bamboo poles and other insulating materials, so that the electric shock can be powered immediately. If the person is in a coma and stops breathing, artificial respiration shall be carried out immediately and sent to the hospital for rescue as soon as possible.

(8) if underground cables are likely to be involved in the excavation of the ground, it is necessary to go through the formalities with the relevant management department first, or contact with the local power supply department, see clearly the marks indicating the location of underground cables, and take reliable measures to prevent accidental injury of cables, causing casualties, power failure and other accidents.

(9) do not stack inflammables such as coal and other articles near the pole, transformer platform, power distribution room and switch box in the building, and build houses. Doing so poses a threat to the safe operation of the equipment, and also causes difficulties to the maintenance and emergency repair of the electrical equipment, affects the fire fighting access, and causes hidden dangers.

(10) do not post propaganda materials on the pole, distribution room and switch box in the building, so as to avoid covering the operation signs and affecting the emergency repair work.

(11) it is strictly prohibited (especially for children) to climb poles, transformers, etc. it is strictly prohibited to open the switch box doors in the distribution room and building without permission to avoid accidents.

(12) it is forbidden to hoist (lift) cars or erect scaffolds near overhead power lines.

General knowledge of safe power use

1. Do not use electricity overload, replace the old power line in time, and use special lines for high-power electrical equipment such as air conditioner, oven, electric water heater, etc.

2. It is strictly prohibited to replace the fuse with copper wire, iron wire and aluminum wire. The fuse suitable for the load of the wire shall be selected and shall not be arbitrarily thickened.

3. Residual current action protector (commonly known as leakage protector) must be installed to prevent leakage. After the protector acts, the cause must be found out and closed after troubleshooting. It is forbidden to remove or bypass the leakage protector.

4. Do not use wet hands to pull out or plug in the power plug, and do not use wet cloth to wipe the live lamp head, switch, socket, etc.

5. It is not allowed to use the method of "one wire one ground" to install the electric lamp.

6. For the connection of household appliances and power supply, the disconnectable switch or plug shall be used, and the wire shall not be directly inserted into the socket hole.

7. Do not pull the wire to pull out the plug or even move the household appliances, and disconnect the power supply when moving the appliances.

8. The ground wire shall be correctly grounded. Do not connect the ground wire to the water pipe or gas pipe, or to the telephone line, radio line or cable TV line.

9. Inflammable and explosive articles (such as gas, gasoline, banana water, etc.) shall not be placed around the heating appliance. Cut off the power supply and unplug the electrical appliance after use.

10. It is strictly prohibited to set up a power grid for guarding against theft, hunting and catching rats, and to use electricity for fishing.

11. To lay wires and connect and install electrical equipment, install and repair electrical appliances, it is necessary to find units and personnel with corresponding qualifications. Do not blindly install by yourself or ask unqualified units and personnel to operate.

Precautions for safe use of electricity at home

A. if you want to add high-power household appliances (such as cabinet air conditioner, etc.) in your home, you need to apply to the power supply department for installation and capacity expansion first. Do not add electric appliances on the original lines without permission.

B. select wires with proper cross-section in strict accordance with the capacity of the electric appliance, and do not blindly increase the electric appliance to make the conductor operate under overload.

C. choose the fuse suitable for the wire. When the fuse is burnt out, never replace it with copper wire, aluminum wire or iron wire. Instead, use the fuse of the same material with the same specification. If it still burns out, either an electrical appliance or a circuit has problems, or the load is too large. Solution: do not use the electrical appliances with high power consumption at the same time.

D. the phase line (also known as the live line) should be put into the switch for control, rather than the zero line. Otherwise, after the switch is turned off, the electrical equipment is still live, which is very dangerous! Before replacing the fuse or overhauling the electrical appliance, the power switch must be opened, and the safety protection measures should be taken, and the live work should not be risked.

E. disconnect the power supply in time after using the electric iron, hair dryer, electric stove and other household appliances. These are heating appliances, which are very easy to cause fire!

D. electric mattress fire. The electric heating equipment of the electric heating mattress is a metal electric heating wire wrapped with insulating materials. Do not fold or rub to avoid open circuit or short circuit fault. Power on for a long time may overheat the bedding and cause fire. Therefore, people should turn off the power when they leave for a long time.

E. do not touch the wire plug or the lamp with the lamp head switch when your hands are wet or sweaty.

F. when the wire is damaged or broken, do not touch it. Disconnect the power supply in time, and then quickly find an electrician to repair it.

H. In case of electric shock, first use an insulator such as a dry wooden stick to remove the power supply. Do not drag the electric shock in the state that the power supply is not separated from the electric shock.

‍ I for the children at home, please take good care of them and don't let them touch the live equipment & ZWJ; & ZWJ; & ZWJ; & ZWJ; & ZWJ;, so as to avoid danger! & ZWJ;

Precautions for safe use of electricity in dormitory

1. Do not change, dismantle or install power lines, sockets, plugs, etc. in the dormitory. Do not chisel iron nails and other hard objects into the wall to prevent accidents such as wire short circuit and electric shock.

2. Don't leave the charger empty on the socket, or make a phone call or play a game while charging, so as to prevent the cell phone from overheating and explosion.

3. It is strictly prohibited to use inferior electrical appliances and high-power electrical appliances in the dormitory, such as electric stove, electric pot, electric mattress, fast heating, kettle, hair dryer, etc.

4. Do not touch or wipe the power supply with hands or conductive objects, such as wire, nails, metal objects, let alone touch the power supply with wet hands, and keep the paper away from the socket.

5. Some charging equipment will cause danger if it is used for too long. When going out, please check whether the charger is in a safe state. If you go out for a long time, you must unplug the power supply, so as to "cut off the power when you leave".

6. It is strictly prohibited to cross the dormitory or pull websites and wires in your dormitory without permission. In case of line failure, it must be reported to the relevant maintenance department for replacement or repair. It is strictly prohibited to replace and repair without permission.
