Electricity safety education

Electricity safety education

Electricity safety education has always been a matter of concern to many people. It is necessary to cultivate children's safety knowledge in all aspects so as to avoid dangers. . Let me take you to learn about the relevant content of electricity safety education. Let’s take a look! Electricity Safety Education 1

10 common sense about safe electricity use that babies must know:

1. Learn to read the safe electricity signs.

Red: Used to mark prohibited and stop information. When encountering a red sign, it is strictly forbidden to touch it. Yellow: used to mark danger. Such as "beware of electric shock", "pay attention to safety", etc.

2. Understand that electric current passing through the human body can cause casualties.

All metal products are conductive. Never use these tools to come into direct contact with the power supply. For example: 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. Usually water is also conductive.

Be careful not to touch electrical appliances with water, so do not touch them with wet hands or wipe them with a wet cloth. For example: when the TV is on, do not wipe it with a wet towel to prevent water from dripping into the casing and causing a short circuit, which may damage the TV and cause personal injury. Do not use wet hands to connect the plug, as this may cause electric shock.

4. If you find someone getting electric shock, try to turn off the power supply immediately.

Do not use your hands to rescue people directly. Call an adult for help. Do not handle it yourself to prevent electric shock. Wood, rubber, and plastic do not conduct electricity and are called insulators. These tools can directly contact the power source and will not cause electric shock. You can use dry wooden sticks and other objects to separate the electric shock victim from the live electrical appliances.

5. Understand the main power switch.

Learn to turn off the main power supply in an emergency.

6. Electrical appliances should be unplugged after use.

Do not pull hard on the wire when plugging or unplugging the power plug to prevent damage to the insulation layer of the wire and an electric shock.

7. Do not disassemble or install power lines, sockets, plugs, etc. at will.

Even simple things such as installing light bulbs must be turned off first and done under the guidance of parents.

8. When you see a fallen wire, be sure to stay away.

Do not touch exposed threads with your hands.

9. There are many dangers next to the switch box.

Do not play near the electric switch, and do not move the electric switch at will to avoid short circuit, leakage and other dangers.

10. Protect against lightning in rainy days.

If it rains, thunders, or flashes, turn off the TV, stereo, and unplug the power plug. Electricity Safety Education 2

The following measures should be taken for indoor electrical equipment:

1. If conditions permit, consider using a low-voltage power supply (such as using a transformer to step down), although 36v is generally Safety voltage of the place, but bathrooms and kitchens are humid places and are special environments with electrical hazards, so 24v safety voltage should be used.

2. When using 220v power supply, install an electric shock safety device or leakage switch. Once the electrical appliances or circuits leak, the power supply will trip.

3. Use flame-retardant trough plates or wire tubes for distribution lines in bathrooms and kitchens. The wiring location should be as far away from bathrooms or water pipes as possible. Distribution lines are strictly prohibited from passing under water pipes, bathtubs or other water-holding appliances. .

4. All metal components in bathrooms and kitchens, such as hot and cold water pipes, various metal pipe heads, floor drains, heating pipe heads, building steel structures and PE wires entering the room should be 20×3mm flat. Steel or copper core wires of no less than 6 square millimeters are interconnected to form a local equipotential bonding network to prevent potential differences caused by external voltage introduction. However, if there is no PE wire indoors, you must not introduce PE wire from outside to avoid introducing undue voltage.

5. Install as few electrical appliances as possible in the bathroom, and it is best not to install other sockets except the special socket for the exhaust fan. If other power sockets must be installed, they must be kept away from water buckets and bathtubs, and equipped with a leakage protector with a starting current of no more than 30ma.

6. Waterproof and moisture-proof lighting fixtures should be used; the installation height of exhaust fans, bathroom heating lamps and lighting equipment should not be less than 2.2m, and heating lamps are generally installed on the bathroom roof.

7. The non-live metal shell of electrical equipment must be grounded (PE wire) according to regulations, and ensure that the grounding resistance is not greater than 4 ohms.

8. All electrical equipment in bathrooms and kitchens must be regularly cleaned of surface oil, dust, etc., and the power supply must be cut off during cleaning; regular maintenance and repair work must be done to eliminate hidden dangers.
