It’s not unusual to hear someone jokingly remark that you are more likely to be hit by lightning than to win the lottery. This may or may not be true, but we suspect that any sensible person would do everything within their power to Lessen their chances of being hit by lightning.
There is no doubt that lightning can be a dangerous natural phenomenon. Just look at how a single strike shattered the bell tower at the St. Mark’s Anglican church a few weeks ago.
But how exposesd is the average person to a lightning strike in the normal course of a day’s activities? Here’s what Dr. Robert Shmerling, of Harvard Medical School had to say on the subject.
“Advice abounds about how to avoid injury from lightning during a storm, but much of what you hear may not be reliable.
“Because being struck by lightning is usually used as a metaphor for something that is exceedingly rare (“that’s about as likely as getting struck by lightning”), it almost seems unnecessary to think about such a thing. But in fact, certain situations greatly increase your chances of being hit by lightning. And although the overall risk remains small, it is worth knowing how to reduce your risk if you find yourself in one of these situations.
“The exact risk of being struck by lightning is difficult to determine. What is clear is that some settings are much riskier than others. For example, if you are caught in a lightning storm while outside in an open space, especially at an elevation, your risk is considerably higher than the estimated overall risk of one in 600,000. (That’s according to the National Oceanic and Atmospheric Administration; other estimates vary from one in 10,000 to one in 5,000,000.)
“In fact, between 1959 and 1994 in the United States, there were more than 3,000 deaths and nearly 10,000 serious injuries resulting from lightning strikes (and these estimates are likely 30 per cent to 40 per cent low). In an average year in the United States, there are more deaths from lightning than from hurricanes or tornadoes, and the estimated costs related to lightning strikes range from $300 million to $5 billion.”
Fact vs. Fiction
Don’t take a bath or shower during a storm. Yes, you can get shocked if you are near pipes or faucets during an electrical storm, so experts recommend that you avoid taking baths or showers when lightning is striking nearby. You also should avoid being near bodies of water if you are outside during a thunderstorm.
Avoid using the phone during a storm. Using a phone with a cord during a thunderstorm is not a good idea because an electrical shock may be transmitted along the phone cord to you. In fact, the use of any electrical appliance should be avoided.
Talking on a cordless phone indoors is not considered a high-risk activity, even during an electrical storm. However, using a cell phone outside should be avoided because the metal in the phone may act as a lightning rod.
Know how to calculate a storm’s distance. If, after you see lightning, you count the seconds until you hear thunder, that amount of time is not equivalent to the number of miles away the storm is. Rather, you should divide the number of seconds by five. For example, if you see a lightning bolt and count 10 seconds before you hear thunder, the source of that bolt is about two miles away.
Don’t take refuge under a tree. In fact, it is best to avoid being near tall objects (which are more likely to attract lightning) during a storm.
Don’t huddle with others. If you are caught out in a storm, it is best to stay at least 15 feet apart from others to reduce the chances that any one person will be struck by a bolt of lightning. If you stay close together, multiple people are more easily injured by a single bolt.
Don’t sit on the ground. If you are caught out in the open during an electrical storm, avoid sitting or lying down on the ground. Most lightning that injures people strikes the earth and travels through the ground; for this reason, the less contact you have with the ground the better.
Ideally, you should avoid trees and other tall structures and avoid open spaces altogether. Seek shelter in a fully enclosed structure (such as a home, school or car). As a last resort, if you are unable to find shelter, crouch down low on the balls of your feet (to minimize contact with the ground).
Don’t try to “read” the sky. If the sky is clear above you or the storm is far away, you can still be struck by lightning. Actually, “bolts from the blue” account for a significant proportion of lightning-related injuries. Because lightning may travel more than 20 miles before touching down, a storm can be in the next town and still cause injury or death.
For this reason, experts recommend that you go inside when the source of lightning is six miles away or closer (that is, if the interval between lightning and thunder is 30 seconds or less) and wait until 30 minutes have passed since the last lightning or thunder struck before you resume outside activities (this is known as the “30/30 rule”).
It is safe to help a lightning victim. One of the most prominent lightning-related myths is that you should not touch a lightning victim or you’ll also be shocked. In fact, it is safe to help a lightning victim. Cardiopulmonary resuscitation and other forms of medical help may save them.
