LIGHTNING (from Wikipedia)
Lightning is a sudden electrostatic discharge during an electrical storm between electrically charged regions of a cloud (called intra-cloud lightning or IC), between that cloud and another cloud (CC lightning), or between a cloud and the ground (CG lightning).


THE NATIONAL WEATHER SERVICE HAS DECLARED THE WEEK OF JUNE
21ST THROUGH 27TH, LIGHTNING SAFETY AWARENESS WEEK. THIS
IS THE LAST IN A SERIES OF FIVE PUBLIC INFORMATION
STATEMENTS TO BE ISSUED BY THE NATIONAL WEATHER SERVICE
OFFICE IN GRAY, ME CONTAINING INFORMATION ON LIGHTNING AND
LIGHTNING SAFETY.

LIGHTNING SAFETY AROUND THE HOME

ALTHOUGH HOUSES AND OTHER SUBSTANTIAL BUILDING OFFER THE
BEST PROTECTION FROM LIGHTNING, EACH YEAR MANY HOMES ACROSS
THE UNITED STATES ARE STRUCK BY LIGHTNING. IN FACT, ON
AVERAGE, LIGHTNING CAUSES ABOUT 4400 HOUSE FIRES AND 1800
OTHER STRUCTURAL FIRES EACH YEAR, SOME OF WHICH ARE DEADLY.
ALL TOTALED, LIGHTNING CAUSES NEARLY $1 BILLION IN DAMAGES
EACH YEAR.

THERE ARE THREE MAIN WAYS LIGHTNING ENTERS HOMES AND
BUILDINGS: (1) A DIRECT STRIKE, (2) THROUGH WIRES OR PIPES
THAT EXTEND OUTSIDE THE STRUCTURE, AND (3) THROUGH THE
GROUND. REGARDLESS OF THE METHOD OF ENTRANCE, ONCE IN A
STRUCTURE, THE LIGHTNING CAN TRAVEL THROUGH THE ELECTRICAL
AND PHONE WIRES, THE PLUMBING, AND/OR RADIO AND TELEVISION
RECEPTION SYSTEMS.

INDOOR SAFETY DEPENDS ON AVOIDING CONTACT WITH ITEMS THAT
COULD CONDUCT LIGHTNING WITHIN THE HOME. HERE ARE SOME
INDOOR SAFETY TIPS TO FOLLOW WHEN A THUNDERSTORM IS IN THE
AREA.


1. DON'T TOUCH ELECTRICAL EQUIPMENT OR CORDS. IF YOU PLAN TO
UNPLUG ANY ELECTRONIC EQUIPMENT, DO SO WELL BEFORE THE
STORM ARRIVES.
2. STAY OFF CORDED PHONES.
3. AVOID CONTACT WITH PLUMBING. DO NOT WASH YOUR HANDS, TAKE
A SHOWER, WASH DISHES, OR DO LAUNDRY.
4. STAY AWAY FROM WINDOWS AND DOORS, AND STAY OFF PORCHES.


IN CASE YOUR HOME IS STRUCK BY LIGHTNING:

* EVACUATE YOUR HOME IMMEDIATELY IF YOU SMELL SMOKE AND
CALL 911.
* CALL YOUR LOCAL FIRE DEPARTMENT AND, IF POSSIBLE, HAVE
THEM CHECK FOR HOT SPOTS IN YOUR WALLS WITH THERMAL
IMAGING EQUIPMENT.
* MAKE SURE ALL SMOKE DETECTORS ARE POWERED AND
OPERATING PROPERLY.
* IF NEEDED, HAVE A LICENSED ELECTRICIAN CHECK THE
WIRING IN YOUR HOME

LIGHTNING QUESTION OF THE DAY: WHAT ARE LIGHTNING RODS AND HOW
DO THEY WORK?

LIGHTNING RODS PROTECT A HOME FROM A DIRECT LIGHTNING STRIKE,
BUT THEY DO NOT PREVENT A HOME FROM BEING STRUCK. THEY ARE
DESIGNED TO INTERCEPT LIGHTNING, TO PROVIDE A CONDUCTIVE PATH
FOR THE HARMFUL ELECTRICAL DISCHARGE TO FOLLOW, AND TO DISPERSE
THE ENERGY SAFELY INTO THE GROUND. WHILE LIGHTNING RODS HELP
PROTECT A STRUCTURE FROM A DIRECT LIGHTNING STRIKE, A COMPLETE
LIGHTNING PROTECTION SYSTEM IS NEEDED TO HELP PREVENT HARMFUL
ELECTRICAL SURGES AND POSSIBLE FIRES CAUSED BY LIGHTNING
ENTERING A STRUCTURE VIA WIRES AND PIPES. LIGHTNING PROTECTION
SYSTEMS SHOULD BE PURCHASED FROM AND INSTALLED BY A CERTIFIED
LIGHTNING PROTECTION SPECIALIST.
