Different Ways Lightning Strikes People

Thunderstorms are in full force across the nation as we head into the summer months meaning lightning strikes are becoming a daily threat. There are various ways lightning can strike people and unfortunately all types can be deadly. We will cover the types below. 

Direct Strike
Direct strikes are potentially the most deadly and often strike people in open areas. Once struck a portion of the current moves over the skin (flashover) while the other portion moves through the cardiovascular and nervous systems. The current on the skin can produce burns but the current through the body is the biggest concern for obvious reasons. 

Side Flash
Victims of side flashes usually are ones that have taken shelter under a tree to avoid heavy rain and hail. With a side flash, the current jumps from the taller object to the victim. With side flashes the victim is most likely within a foot or two from the object that is struck. 

Ground Current
When lightning strikes an object, the energy spreads outward along the surface. This is called a ground current and is the leading type of lightning that causes injuries and fatalities. Interestingly enough, this type of lightning is often fatal to livestock since their large frames allows the current to travel a further distance throughout their cardiovascular and nervous system.

Conduction 
Metal does not attract lightning, but it does give it a path to follow if it’s struck. Most indoor casualties are from conduction which is when a person is in contact with water faucets, showers, corded phones, electrical outlets, etc., during a thunderstorm.

Streamers
Streamers are basically a mini lightning bolt near the main lightning strike. These occur after the main bolt discharges disallowing the streamers to fully connect their current. While these are not as common as other lightning strikes, they can be deadly. 

Remember when thunder roars, head indoors. If shelter isn't an option, discard any metal or graphite objects, move out of open areas and head towards bushes or rocks of similiar size. Then, squat down with your head low being sure to not touch the ground with any other part of your body. Avoid taking cover under isolated trees or other tall objects. If you witness someone hit by a lightning strike, the victim will need immediate medical attention. This includes calling 911, starting CPR, and potentially using an automated external defibrillator (AED).
