Yes, generally it is safe to use WiFi devices indoors during a lightning storm.
While lightning strikes are a serious safety concern, using wireless devices like smartphones, tablets, and laptops connected to WiFi is usually safe inside a building during a thunderstorm. This is because WiFi devices are not directly connected to the outside electrical grid in the same way that corded phones or plugged-in appliances are. Lightning travels through conductive materials, and those direct wired connections present a path for electricity to enter the building.
Here's a breakdown:
-
Wireless vs. Wired Connections: The key difference lies in the connection type. WiFi utilizes radio waves, which are not conductors of electricity, to transmit data. This means there's no direct electrical connection to the outside world through your device.
-
Electrical Surge Risk: The greater risk during a lightning storm comes from electrical surges travelling through your home's wiring. These surges can damage devices that are plugged into electrical outlets, like computers, TVs, and lamps.
-
Router and Modem Safety: Your WiFi router and modem are connected to electrical outlets and potentially cable/phone lines. Therefore, they are susceptible to damage from lightning strikes and power surges. Consider using surge protectors for these devices.
-
Phone Lines: Corded phones are not safe to use during a lightning storm. They are directly connected to the phone lines, which can conduct electricity.
-
General Safety Precautions: Even though using WiFi is generally safe, it's always a good idea to take precautions during a lightning storm:
- Avoid using corded phones.
- Unplug sensitive electronic devices from electrical outlets to protect them from power surges.
- Stay away from windows and doors.
- Do not take a bath or shower.
- If outdoors, seek shelter indoors.
In summary, using WiFi devices themselves is generally safe during lightning, but protect the equipment they connect to (router/modem) and avoid wired connections.
