Lightning usually occurs in clouds, but this extreme phenomenon also “likes” atmospheric discharges between clouds and the ground, or clouds of opposite charge.

Lightning tends to strike tall or isolated objects, including trees, towers, roofs, flagpoles, doorways, and fences. A person can be the tallest object in the void. Metal objects and water do not attract lightning but easily transmit electricity once lightning strikes.

Lightning can also travel from outdoor power or power lines to indoor electrical equipment or telephone lines. Lightning strikes can throw people up to several meters.
According to Dr. Nguyen Thong – former head of Burns Department, Saint Paul General Hospital, Hanoi, lightning strikes are like burns caused by electric shock. Victims of lightning strikes are often severely burned. Lightning strikes are much more dangerous than electric shocks because they are considered super high voltage currents. Therefore, most lightning victims die.
In addition, lightning strikes ordinary people in a situation in the middle of a deserted place, under a tree, next to an electric pole, not in a community where there are many people. Therefore, most lightning victims receive little first aid.
Burns caused by lightning are treated like electric burns, many patients have to cut the skin, skin grafts. First aid for victims of lightning strikes must first determine the emergency to stop the patient’s circulation.

– After giving first aid and first aid to the victim, it is necessary to quickly bring the victim to the nearest medical facility. Note, safely transport multi-trauma patients after securing the airway, firmly immobilizing the cervical spine and fractures, having at least 2 lines, and attaching a monitor to monitor stable vital signs within range. control. Check every 5 minutes during patient transport to hospital.
To prevent lightning strikes, Dr. Thong added that it is best to limit going out when the weather has thunderstorms accompanied by thunder. People who are working outdoors should find safe shelter, avoid standing under trees, electricity poles and telephone transceivers.
If you can’t get to a safe place in time, you should hide in the lowest place, crouch and put your feet together, to find a safe, dry place, preferably a large building (if any). Never use your phone while outdoors with thunder.
If at home, it is raining, so unplug the circuit breaker, unplug all the power sockets to avoid high voltage damage to items, house fire ..
