Which of the following is NOT a precaution during thunderstorms?

Using tools made of metal during thunderstorms is indeed not advisable and is the correct answer to the question about precautions. Metal is a conductor of electricity, and using metallic tools can increase the risk of being struck by lightning, especially if you are outdoors.

On the other hand, seeking shelter indoors is a fundamental safety measure during a thunderstorm as it provides protection from both lightning and severe weather conditions. Staying away from tall structures is also a precaution since these structures can attract lightning strikes. Monitoring weather updates helps keep you informed about the storm's status and any warnings, allowing for timely safety measures to be taken.

Overall, recognizing the dangers associated with metal objects during thunderstorms highlights the importance of adhering to safety practices designed to minimize risk during severe weather events.
