The
electrical current from lightning still causes severe injury and even death.
That’s because the salty water in the human body conducts lightning better
than open air. In open areas, this makes the body a target.. Lightning
strikes kill up to 100 and injure up to 1,200 each year, according to the
National Oceanic and Atmospheric Administration(NOAA).
Weather forecasts and warning systems
have improved greatly. Millions pay close attention to the TV weather maps
for their areas. While most golf courses now have sirens that alert golfers
to leave the course when lightning approaches, hikers, campers and
agricultural workers rarely have such advance warning.
(Bridge)By following certain personal
precautions, the toll from lightning can bereduced.
Can you name some
kinds of exposure you should avoid?
