Suggest three measures to protect ourselves from lightning.
Share
There are three effective measures to protect oneself from lightning during a thunderstorm:
1. Seek Proper Shelter: Immediately seek sturdy, enclosed shelters like buildings or fully enclosed vehicles when thunderstorms approach. Avoid open spaces, tall objects, or isolated trees, and refrain from seeking shelter in sheds or small structures that don’t provide adequate protection from lightning.
2. Avoid Conductive Surfaces: Stay away from conductive surfaces and objects that can conduct electricity, such as metal fences, wires, plumbing, and electronic devices. Additionally, avoid contact with water sources like pools, lakes, or showers, as water conducts electricity.
3. Follow the 30-30 Rule: Use the “30-30 rule” during a thunderstorm. Count the seconds between a lightning flash and the sound of thunder. Seek shelter if this time is 30 seconds or less. Stay indoors for at least 30 minutes after the last observed lightning or thunder to ensure safety.
Implementing these precautions significantly reduces the risk of lightning-related injuries, providing safety during thunderstorms and adverse weather conditions.
Safety Measures during Lightning:
• Open space is dangerous. Take cover under a building.
• Thunder storm is an indication to rush for safer place.
• Once thundering stops, move out to an open place.
