Electrical Safety During Lightning Storms

Lightning storms are awe-inspiring natural phenomena, but they can also pose significant risks to human safety and property, particularly when it comes to electrical systems. Lightning carries immense electrical energy that can cause fires, damage electronics, and endanger lives. This article provides a comprehensive guide on how to ensure electrical safety during lightning storms.

1. Stay Informed

  • Before a lightning storm strikes, staying informed is essential. Keep an eye on weather forecasts and warnings through various sources, such as weather apps, websites, or radio broadcasts. Being aware of impending thunderstorms allows you to prepare in advance and take necessary precautions.

2. Seek Shelter

  • The best place to stay when there’s lightning is inside a building. Seek refuge in a sturdy building that has wiring and plumbing. Avoid open fields, isolated trees, bodies of water, and tall objects like flagpoles. If you are caught outdoors without access to a building, shelter in a fully enclosed metal-topped vehicle (not a convertible).

3. Unplug Electrical Appliances

  • To prevent damage from power surges caused by lightning strikes, unplug electrical appliances and devices, including computers, televisions, modems, and other sensitive electronics. This simple step can protect your valuable equipment from being fried by electrical surges.

4. Avoid Corded Communication

  • During a lightning storm, avoid using corded telephones or other wired communication devices. Lightning can travel through wiring and plumbing, putting you at risk of electrical shock. Instead, use a cordless or mobile phone to communicate.

5. Surge Protection

  • Consider installing surge protectors or lightning arrestors in your home’s electrical system. Surge protectors help divert lightning-induced power surges away from sensitive equipment, while lightning arrestors can dissipate the electrical energy safely into the ground. These devices provide an extra layer of defense for your home and electronics.

6. Ensure Proper Grounding

  • Proper grounding is crucial for electrical safety during lightning storms. A well-grounded electrical system provides a safe path for lightning to follow into the ground without causing damage. Consult a qualified electrician to assess your home’s grounding system and make improvements if necessary.

7. Lightning Rods

  • For tall structures like homes, barns, or commercial buildings, lightning rods, also known as air terminals or lightning conductors, can be a lifesaver. These devices are designed to divert lightning away from structures and safely into the ground. It’s essential to have lightning rods professionally installed to ensure their effectiveness.

8. Stay Inside

  • If you find yourself outdoors during a lightning storm and cannot reach shelter, follow these safety precautions:
  • Avoid open areas, bodies of water, and tall objects.
  • Crouch down low on the balls of your feet to minimize contact with the ground.
  • Make yourself as small a target as possible by keeping your body close to the ground.

9. Wait for the All-Clear

  • Even after a lightning storm appears to have passed, it’s crucial to exercise caution. Wait for at least 30 minutes after the final thunder sound before you go outside from your safe place. Lightning can strike outside of the immediate storm area, so waiting for the all-clear reduces the risk of danger.


Electrical safety during lightning storms should never be taken lightly. By staying informed, seeking proper shelter, and taking precautions such as unplugging electrical devices, using surge protectors, ensuring proper grounding, and considering lightning rods, you can significantly reduce the risks associated with lightning strikes. Remember that lightning is a powerful natural force, and being prepared can make all the difference in keeping yourself and your property safe during thunderstorms.
