In case of lightning, what is the safest action to take?

Seeking shelter in buildings during a lightning storm is the safest action because enclosed structures provide a protective barrier between individuals and the dangers of lightning strikes. Buildings have grounding systems that safely redirect electrical currents from a lightning strike into the ground, minimizing the risk of injury.

The other choices pose significant risks. Staying outdoors and seeking shelter under a tree can be particularly dangerous, as trees can attract lightning, creating a high risk for anyone nearby. Running into an open field exposes individuals to direct lightning strikes, as being in an open area increases vulnerability during a storm. Lastly, while using a vehicle may provide some protection, it is not as secure as taking shelter in a building. A vehicle can be safer than being outside, but the best option remains seeking a solid, indoor shelter to ensure maximum safety from lightning.
