No, it is generally not safe to use the toilet during a thunderstorm.
During a thunderstorm, lightning can strike your home, and the electricity can travel through plumbing. Plumbing, including metal pipes and the water within them, is an excellent conductor of electricity. If lightning strikes your home and travels through the plumbing, you could be electrocuted if you are in contact with any part of that plumbing system, including the toilet.
Here's a breakdown of the risks:
- Metal Pipes: Most homes have metal plumbing pipes that can conduct electricity very well.
- Water Conductivity: Water itself is also a good conductor of electricity, increasing the risk of shock.
- Proximity to Plumbing: Using the toilet brings you in close proximity to plumbing fixtures, increasing the risk of electrical shock if lightning strikes.
Therefore, it's best to avoid using the toilet, washing hands or dishes, showering, bathing, or doing laundry during a thunderstorm to minimize the risk of electrical shock. Wait until the storm has passed before resuming these activities.
