![]() ![]() Streamer strikes are not as common as the other types of strikes. If a person is involved as one of the streamers that discharge after a lightning strike has occurred, that individual could be seriously injured or killed. Streamers can extend from things such as the ground surface, a tree, or a person. Once a lightning strike has occurred, other streamers in the area discharge. When the positive streamers extend toward the negative ions and make contact with a step leader, lightning strikes. The negatively charged ions, also called step leaders, create an electric field as they move toward the ground. Positive streamers are positive ions that extend upward from the ground. Streamers: Before a lightning current forms, the negatively charged particles at the bottom of a cloud are attracted to the positively charged ground and positive streamers in particular.People should stay away from conductive objects, such as windows, doors, and objects connected to electrical outlets during storms. Most indoor lightning strikes occur as a result of conduction. Although metal does not attract lightning, it is a good conductor of electrical current. Conduction: Conduction lightning strikes occur when lightning travels through conductive objects, like metal wires or plumbing, to strike a person.Ground current may travel through any type of conductive material, including garage floors. As the current travels through the body, it can cause extensive damage to the body's cardiovascular and nervous systems. As the current comes in contact with a person, it enters the body at a point closest to the current and exits at a contact point furtherest away from the lightning. Ground current strikes cause the most lightning strike-related deaths and injuries. Ground Current: This type of strike occurs when lightning strikes an object, like a tree, and part of the current travels along the ground and strikes a person. ![]() This type of strike often occurs when a person is seeking shelter under tall objects, such as a tree. The person is typically in close proximity to the object that has been struck, about one to two feet away.
