Lightning Safety
More people are killed in the U.S. by lightning each year than by tornados and hurricanes. An average of 62 people are killed each year by lightning in the United States. In 2007, 45 people were struck and killed by lighting in the U.S., and hundreds of others were injured.
If you are outside and can see lightning or hear thunder, you are at risk and should seek shelter. Most lightning injuries and fatalities occur when people are caught outdoors in the summer months during the afternoon and evening.
- Seek safe shelter when you first hear thunder, see lightning, or dark, threatening clouds developing overhead. Count the seconds between the time you see lightning and hear the thunder; if that time is less than 30 seconds, you should already be in a safe location.
- Be aware that storms may also bring high winds or hail. Should a storm develop, move away from any windows exposed to the impact of high winds, such as into a protected area or hallway.
- Postpone outdoor activities if thunderstorms are imminent.
- Plan ahead so that you will know in advance where you can quickly seek shelter.
