PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SAN DIEGO CA
800 AM PDT FRI JUN 27 2014

THE NATIONAL WEATHER SERVICE HAS DECLARED THE WEEK OF JUNE 22ND
THROUGH 28TH, 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 SAN DIEGO, CA 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.
