Lightning hazard and electric shock accident

According to the data of the National Oceanic and Atmospheric Administration (NOAA), about 25 people in the United States have died from lightning strikes every year in the past decade. In fact, lightning deaths can be avoided in most cases. We need to pay more attention and smash relevant rumors. So what are the rumors about lightning strikes?
Rumor 1: almost all people who were struck by lightning were not spared.
Fact: in fact, many people can escape, but the victims may suffer permanent physical injury and impact.
The study found that 9 out of every 10 people struck by lightning in the United States can survive, in part because most of the energy of lightning has dissipated when it reaches the human body, and most of the current passes through the human body rather than directly into the human body. John jensennieus, a lightning safety expert at the national weather service, said that the biggest risk caused by lightning is cardiac arrest, so one of the keys to survival is timely cardiac resuscitation after lightning. Lightning strikes may have a long-term impact on health. Some people will feel headache, nausea and even amnesia.
Rumor 2: if you wear rubber soled shoes, you won’t be struck by lightning; If you wear metal clothes, you will be struck by lightning.
Fact: lightning “hits wherever it wants”.
Jensennieus said that people’s clothes will not affect the direction of current up to 2 million volts. This rumor is also very common. There are many claims that some things will attract lightning or protect people from lightning. In fact, it is possible for lightning to hit any object. Wearing metal bracelets does not mean that lightning will cause people to die by electric shock. Whether you will be hit by lightning has a lot to do with where you are. Lightning tends to hit relatively high objects, so if you want to reduce the risk of being hit by lightning outdoors, you should avoid making the human body a relatively high object and stay away from relatively high objects (such as isolated trees and towers).
Rumor 3: after entering the house, you won’t be struck by lightning.
Fact: stay away from conductive objects even indoors.
There is no guarantee that it will not be struck by lightning indoors. The National Weather Service said that when a storm comes, it is best to stay away from wired phones, electrical appliances, wires, TV antennas, computers, water pipes, metal doors and windows indoors.
Rumor 4: if you touch a lightning victim, you will also be shocked.
Fact: it’s safe to touch the lightning victim during first aid.
This rumor is the most “dangerous” because CPR plays a vital role in saving the people who were struck by lightning. Many lightning victims need immediate medical treatment because they are likely to have cardiac arrest. Generally speaking, the duration of a lightning is less than 1 second. Unlike ordinary electric shock accidents, there may be continuous current, so it is safe to touch the lightning victim during first aid.
