MANY INJURIES SUSTAINED DURING A TORNADO ARE THE RESULT
OF FLYING DEBRIS.
-- MICHELLE --
SO RIGHT HERE IN MADISON.
A RESEARCHER IS TRYING TO HELP PROTECT US BY MAKING
OUR HOMES SAFER IN A SEVERE STORM SITUATION.
NEWS THREE METEROLOGIST KARIN SWANSON JOINS US WITH
RIGHT NOW, FEMA'S NORMAL SAFE ROOM DESIGN INCLUDES
A WOOD WALL FILLED WITH BRICK AND REINFORCED WITH
IT CAN BE DIFFICULT TO BUILD AND CAN COST AS MUCH
AS FIFTEEN THOUSAND DOLLARS.
BUT WORK IS BEING DONE RIGHT HERE IN MADISON TO BUILD
A NEW SAFE ROOM DESIGN THAT IS MUCH MORE FEASIBLE.
THE FOREST PRODUCTS LABORATORY IN MADISON ISN'T EXACTLY
THE TYPE OF SETTING YOU WOULD EXPECT TO SEE FOR A
BUT IT'S HERE THAT BOB FALK HAD AN IDEA TO HELP KEEP
I woke up one night and said oh there's a better way
to do this.
I can stack two by fours up.
Just stack them straight up, right.
Nail them all together.
That should work really well.
The two by four just flew right through and smacked
into the back wall and it just pierced right through.
THAT DIDN'T DETER BOB.
HE TRIED AGAIN, USING THE KIND OF WOOD THAT YOU'D
GET FROM YOUR LOCAL HARDWARE STORE.
THE IDEA IS TO KEEP PEOPLE SAFE, WHETHER THEY LIVE
IN TORNADO ALLEY, OR RIGHT HERE IN WISCONSIN.
AND TO DO IT AT PRICE PEOPLE CAN AFFORD.
We're trying to use the lowest quality wood materials.
The lowest quality lumber to make it as cheap as possible
and make it work under the most severe tests.
THE GOAL IS TO SIMULATE AN EF-5 TORNADO.
TO DO THAT, HE LAUNCHES A FIFTEEN FOOT TWO BY FOUR
AT 100 MILES PER HOUR.
THE DESIRED RESULT IS TO HAVE THE TWO BY FOUR HIT
THE WALL AND BOUNCE OFF WITHOUT PIERCING THE WOOD.
TODAY'S TEST WAS TECHNICALY A FAILURE, BECAUSE THE
BACK SIDE OF THE WALL BOWED OUT MORE THAN THREE INCHES.
You know the wood will fail, but the idea is that
when it fails, it's absorbing some of the energy.
And so that helps protect the occupant.
That helps dissipate the energy.
EACH TIME A TWO BY FOUR IS LAUNCHED AT THE TEST WALL,
BOB IS LEARNING AND MAKING ADJUSTMENTS TO THE STUDY.
What we've learned here is that this layered design
here is effective.
And we're going to go on and look at different nail
We're going to look at the possible use of construction
Look at plywood versus strandboard.
THE FOREST PRODUCTS LABORATORY HAS PARTICIPATED IN
OTHER DISASTER MITIGATION RESEARCH AS WELL.
THEY HAVE DONE WORK ON HURRICANE STUDIES IN THE PAST
RESULTING IN BETTER AND SAFER HOUSING.
