Thunderstorms that produce lightning are most likely to develop on hot, humid days. These storms can be very dangerous, especially if a person is outdoors. If lightning is seen, protective action should be taken immediately.
Five Ways Lightning Can Severely Injure Or Kill
- Direct Strike: usually results in cardiac arrest and/or stoppage of breathing.
- Side Flash: occurs when a person is another route for the current to reach the ground. Death can result if the current passes through the heart or head.
- Step Voltage: spreads out through the ground from a struck pole or tree.
- Conducted Current: from poorly grounded electric power pole, through the wiring system. Can range from mild tingling shock to a massive current.
- Secondary Effects: can be from fires, fallen trees, etc., that occur as the result of a lightning strike.
Protection During Storms
- Seek shelter inside a building, car, or truck and close all windows and doors.
- Turn off all electrical appliances and unplug them if possible.
If Stranded Outside
- Stay away from tall, isolated objects such as trees, poles, clotheslines, etc.
- Avoid metal objects such as pipes, chain link fences, electric fences, etc.
- Drop objects that may conduct electricity such as pitch forks, rakes, hoes, etc.
- Standing under a group of trees that are shorter than others in the area is better than standing out in the open.
- Seek low ground such as ditches or gullies.
- Make your body low to the ground but do not lie flat. Curl into a fetal position or get on your knees and lay your body forward.
- If you are in a group of people, spread out.
- Stay clear of downed power lines and report them to police immediately.
