>> THE NASA LANGLEY STEAM PLANT
MAINTAINS OVER TWO MILES
OF UNDERGROUND TUNNELS THAT
STRETCH TO NEARLY ALL
OF THE CENTER'S 250 BUILDINGS.
THESE UTILITY TUNNELS ARE
IN SERVICE 24/7,
365 DAYS A YEAR.
THE HIGH ENERGY OF
THESE UTILITIES, COMBINED WITH
DANGEROUS CONDITIONS WITHIN
THE TUNNELS, MEANS THAT
YOUR SAFETY IS CRITICAL.
IF YOU'RE GONNA ENTER
A UTILITY TUNNEL HERE AT
NASA LANGLEY, THIS VIDEO WILL
TELL YOU WHAT YOU NEED TO KNOW
AND WHAT CONDITIONS TO EXPECT.
SO LET'S GET STARTED.
ALL VISITORS TO BUILDING 1215
MUST CHECK IN WITH
THE PLANT OPERATOR AND OBTAIN
PERMISSION TO ENTER THE TUNNEL.
THEN YOU'LL BE ASKED TO WATCH
THIS VERY IMPORTANT
SAFETY VIDEO.
[ INDISTINCT CHATTER ]
>> THE BUDDY SYSTEM IS REQUIRED
WHEN INSIDE A UTILITY TUNNEL.
AND YOU MUST ALWAYS REMAIN
IN LINE OF SIGHT OF EACH OTHER.
AS YOU ENTER THE TUNNEL,
PAY ATTENTION TO
THE AIR LOCK DOORS.
THE FIRST DOOR MUST BE TIGHTLY
CLOSED BEFORE THE SECOND DOOR
IS OPENED TO AVOID
VERY SERIOUS HAND INJURIES.
STEAM PLANT PERSONNEL
WILL GIVE YOU THE SAFEST
AND MOST EFFICIENT ROUTE
TO AND FROM YOUR WORK AREA.
WHEN YOU GET TO THE LOCATION
WHERE YOU'LL BE WORKING,
SIMPLY LIFT THE NEAREST
BLACK PHONE AND NOTIFY
THE PLANT OPERATOR THAT
YOU ARE AT YOUR WORKSITE
AND HAVE LOCATED
THE NEAREST EXIT.
[ MUSIC ]
>> IN THE EVENT OF AN EMERGENCY,
STEAM PLANT OPERATORS
WILL FLICK THE TUNNEL LIGHTS
OFF AND ON, SIGNALING YOU
TO LEAVE.
WHEN EXITING THE TUNNEL
THROUGH A HATCH FOR ANY REASON,
ALWAYS NOTIFY THE OPERATOR
BY USING THE BLACK TELEPHONES.
>> STEAM PLANT.
>> AND NEVER LEAVE
OPEN HATCHES UNATTENDED.
IMMEDIATELY CLOSE HATCHES
AFTER ENTERING OR EXITING
TO PREVENT TRIPS OR FALLS.
PIPING INSIDE UTILITY TUNNELS
CAN BE FOUND ALONG THE GROUND,
WALLS, AND CEILING.
THESE PIPES CAN BE EXTREMELY
HOT, AS HOT AS 425 DEGREES.
PRECAUTIONS SHOULD BE TAKEN
TO PREVENT BURNS.
NEVER TOUCH UNINSULATED PIPING.
PROTECTIVE CLOTHING LIKE
LONG SLEEVES, LONG PANTS,
AND EVEN KEVLAR SLEEVES
ARE APPROPRIATE.
WHILE WORKING, CONTINUE
TO DRINK WATER.
YOU SHOULD BE CONSUMING
8 OUNCES EVERY 15 TO 20 MINUTES.
THERE ARE ALSO COOLING VESTS
AVAILABLE IN THE STEAM PLANT
OFFICE.
YOU SHOULD CONSTANTLY MONITOR
YOUR BUDDY AND OTHERS
IN YOUR TEAM FOR
HEAT STRESS SYMPTOMS.
IF ANY EMPLOYEE IS SUFFERING
FROM HEAT-RELATED ILLNESS
OR SHOWING SIGNS OF DISTRESS,
REMEMBER: USE THE RED
EMERGENCY PHONE TO GET HELP,
THEN ASSIST HIM OR HER
TO THE NEAREST EXIT IMMEDIATELY.
