Good broadcast scripts will bring more For good program effects, how to highlight the key points in the broadcast script? The following is a summer lightning protection safety education broadcast script that I carefully compiled. I hope it can help everyone.
Summer Lightning Protection Safety Education Broadcast Draft 1
The car is an ideal place for lightning protection
If you are driving during a thunderstorm, you should try to stay in the car . Outdoors, cars are an ideal place to avoid lightning strikes due to the Faraday cage effect.
Lightning protection experts say that the Faraday cage is a closed metal cage. The Faraday cage is charged, but its internal field strength is zero, so the people inside the Faraday cage are safe. Therefore, a car can also be regarded as a Faraday cage. The body of the car will be charged due to lightning strikes, but the people inside the car will not be electrified.
Don’t run away when lightning strikes
Lightning protection experts say that when many people encounter lightning in the wild, their instinctive reaction is to walk quickly or even run. In fact, this is a taboo for lightning protection. . This is because the ground may form a potential difference during thunder, which creates a "step voltage" for pedestrians (the voltage between a person's feet when walking on ground with different potentials). If you walk or run quickly, the "step voltage" will be correspondingly larger, making people more likely to be injured.
If you encounter lightning in the wild, you should evacuate to a house or reinforced concrete building with lightning protection facilities, and stay away from tall chimneys, big trees, iron towers, telephone poles and other objects. If there is no time to evacuate, do not run around. You can choose to squat in a low-lying area, put your feet together, hug your knees with your arms, and bend your head down to reduce the exposed area of the human body and the difference in ground potential.
These places are vulnerable to lightning strikes
1. Places with low soil resistivity, such as areas with metal deposits, riverbanks, underground water outlets, intersections with concentrated metal pipelines, and railways Concentrated hubs, rail terminals and corners of elevated transmission lines.
2. High water levels and particularly humid areas, such as river beds, salt fields, reed ponds, lakes, low-lying areas and places with high groundwater levels. Because the probability of being struck by lightning is greater on water than on land.
3. The junction between the hillside and the rice fields.
4. Boundary areas with different resistivities (such as rocks and soil).
5. Tall and prominent buildings, such as water towers, television towers, flagpoles, etc.
6. Buildings (structures) and trees isolated and protruding in the wilderness.
Remember these lightning protection tips
1. Pay attention to the lightning warning issued by the meteorological department when the weather changes.
2. Do not stay on the floor (roof) of a building during thunder.
3. Be careful to close doors and windows when there is thunder.

If you find that an outdoor line is broken, you should keep a safe distance from the point of fall and seek help from the power department in a timely manner.
3. Which places are prone to lightning strikes?
Generally speaking, lightning strikes are likely to occur in places where the soil resistivity is small and the soil resistivity changes significantly. Areas with metal deposits, river beds, groundwater outlets, areas where hillsides meet rice fields, hillsides and foothills, riversides, lakesides, seasides, low-lying areas and places with high groundwater levels are all places prone to lightning strikes. Some isolated iron towers, chimneys and other tall buildings are also vulnerable to lightning strikes. When thunderstorms come, because trees are relatively tall, they are prone to lightning. During thunderstorms, stay away from big trees and squat as low as possible with your feet together.

5. If a household appliance catches fire, you should first cut off the power supply and then put out the fire. Do not put it out directly with water to prevent electric shock.
8. Why should we pay more attention to preventing electric shock accidents in summer? How to prevent it?
Summer is hot and hot, and household appliances are used frequently at this time. In hot seasons, people sweat a lot, and their hands are often sweaty, and sweat is conductive. Therefore, special attention should be paid in summer:
1. Do not use your hands to move running household appliances, such as table fans, washing machines, TVs, etc. If it must be moved, turn off the switch and unplug it.
2. Do not repair live wiring or equipment in your home with bare hands and feet. If electrical repairs are necessary, wear shoes and gloves.
3. For electrical appliances that are frequently used in summer, such as electric showers, table fans, washing machines, etc., some practical measures should be taken to prevent electric shock. For example, often use an electric pen to test whether the metal casing is charged, and install additional Electric shock safety device (leakage switch), etc.
4. If your home is accidentally flooded, you should first cut off the power supply, that is, pull out the main switch or fuse in your home to prevent accidents caused by water immersion and insulation damage to household appliances in use. Secondly, after cutting off the power supply, move household appliances that may be immersed in water to a place where they are not immersed in water to prevent the insulation from being soaked in water and getting damp, which will affect future use. If electrical equipment has been immersed in water, the insulation resistance of the equipment's insulation should be tested with a special megger before use again. It can only be used if it meets the specified requirements. Otherwise, the insulation must be dried until the insulation is good.
9. What are the most basic common sense to prevent electric shock in bad weather?
1. In severe weather such as strong winds and thunderstorms, going out should be minimized. If you must go out for a walk, you should carefully observe the terrain and walk carefully to avoid stepping on power lines. You should avoid walking near power facilities such as telephone poles and towers, and avoid hanging wires.
2. Do not go barefoot when walking outside.
3. Indoors, if you encounter thunderstorms and strong winds, you should promptly turn off running household appliances and unplug them; do not repair live wires or equipment at home with bare hands and feet; if your home is accidentally flooded , the power supply should be cut off immediately to prevent accidents caused by water intrusion and insulation damage to household appliances in use.
4. When walking outside on rainy days, pay attention to observation and avoid contact with the metal parts of street light poles, signal light poles and floor-standing billboards. Avoid areas with accumulated water.
5. After discovering that power facilities such as switchboards and box-type substations are submerged in water, you must promptly notify the power supply department for processing while staying away from other people.
