What would happen to a person if he was hit by a thunderbolt?

Will he die immediately?

The victim can go into coma with severe injury. He might die immediately due to severe body damage or due to the stopping of heart beat and breathing.

He may have unsual pattern of burn mark on the body. His mental status can be changed. The lightning shock can stop the heart beating and stop the person's breathing. In addition, there may be severe damage inside the brain, eye and ears. The victim may fall from height secondary to coma

The flashover phenomenon channels most of the current over the skin rather than the body. It vaporizes moisture on the skin and can destroy the victim's clothing in an explosive manner.

If you saw somebody hit by lightning and wanted to save him, you should first make sure that you are safe before trying to do so. Start the proper cardiopulmonary resuscitation procedure (you must learn it properly in centres like the Red Cross and St's John's Ambulance) immediately if the patient got into coma with no pulse and no breathing. Look for any active severe bleeding due to trauma wound. You have to compress the major bleeding wound by any means to prevent the patient loosing his blood. Call for help.

It is reported that some victims have been successfully resuscitated after a long period of Cardiopulmonary resuscitation (CPR).

Subject: 必知常識, 如果唔係隨時冇命

有位女子站在美國.加州美洲杉國家公園 (Sequoia National Park) 的
觀景平台時,突然發現她的頭髮忽然豎立起來,當時周圍的遊客都覺得
很有趣,她的弟弟並為她拍下了這張照片。這對姐弟離開五分鐘之後,
閃電墼擊中觀景平台,造成一個人死亡,七 個人受傷。

將來如你在野外遇到類以的狀況,請立即離開該地點,儘速往較低處移
動,否則後果不 堪設想。

Should one avoid all hiking activities when there is a Thunderstorm Warning by the HKO? If not, what should one do to mitigate the risk?

   By Outdoor Doctor (Doctor) on Wednesday, July 12, 2006 - 11:13 pm:  Edit

When there is a high chance of thunderbolt, one should avoid outdoor activities. It unavoidable (e.g. thunderbolt occurs during a long trekking trip), you should go a low-level place to minimize the risk of being hit by the thunderbolt.
