Ask the caller how many
seconds there are between the lightning
flash and the associated sound of thunder.
If the count is 30 seconds or less,
the caller is at risk for further
strikes. If the count is less than
10 seconds, the caller is in grave
and imminent danger.
Tell the caller...
Your house is the safest
place to be in a lightning storm. If you
are inside, stay there. Avoid windows
and electrical appliances.
If you are not inside,
and lightning is still striking nearby,
you must get to a safe place immediately.
Get inside a house or building, or into
a metal-roofed car, and roll up the windows.
Unless you are on a portable
or cell phone, hang up until the lightning
has passed. Lightning can travel along
phone lines and injure or kill you.
Call back if you see
lightning hit something such as a person
or a structure.
