Lightning Safety at Home: What to Avoid Indoors During Thunderstorms
Indoor lightning safety tips: plumbing, corded electronics, windows, porches, garages, pets, and when it is safe to resume normal activity.
Why indoor risk exists
Lightning can travel through wiring, plumbing, metal framing, phone lines, and other conductive paths. A house greatly reduces risk, but it does not make every contact safe.
The safest indoor habit is simple: stay away from things that connect you to outside conductors.
What to avoid
Do not shower, wash dishes, use corded phones, lean on windows, or stand in open garage doors during a thunderstorm.
Unplug sensitive electronics before storms arrive if you can do so safely. Do not unplug devices while lightning is already close.
Safer places and activities
Interior rooms away from windows are better. Wireless devices on battery power are generally safer than corded devices.
Bring pets inside early. Dogs, cats, and livestock can be frightened by thunder and may run if doors or gates are open.
When it is safe again
Use the common 30-minute rule: wait at least 30 minutes after the last thunder before resuming outdoor activities.
If thunder is audible, lightning is close enough to be a concern.
