Answer

To stay safe during lightning, it is important to follow certain precautions. Here’s a step-by-step solution to the question:

### Step-by-Step Solution:

1. **Understanding Lightning**:
- Lightning is a natural electrical discharge that occurs during a thunderstorm. It can be very dangerous, and knowing how to protect yourself is crucial.

2. **Avoid Sitting Under Trees**:
- One common misconception is that sitting under a tree can provide shelter. However, this is unsafe because trees are more prone to being struck by lightning. If lightning strikes a tree, it can cause electric shock or fire.

3. **Keep Doors and Windows Closed**:
- During a lightning storm, it is important to keep all doors and windows closed. Open doors and windows can allow lightning to enter the building, which can be dangerous.

4. **Take Shelter Inside a Building**:
- The safest option during a lightning storm is to take shelter inside a sturdy building. If lightning strikes the building, the electrical discharge will travel through the building's grounding system and go safely into the ground, protecting you from harm.

5. **Stay Away from Buildings and Poles**:
- This advice is often confused with safety measures for earthquakes. During a lightning storm, you should not stay away from buildings or poles; instead, you should be inside a building. Staying away from tall structures is relevant during an earthquake, not during lightning.

### Conclusion:
The best precaution to take during lightning is to stay indoors in a safe, sturdy building with doors and windows closed.
