Ingredients

NITROGEN

CAS: 7727-37-9

RTECS: QW9700000

ACGIH TLV: ASPHYXIANT; 9192

Hazards

Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:AT LOW OXYGEN CONCENTRATIONS
UNCONSCIOUSNESS & DEATH MAY OCCUR IN SECONDS W/OUT WARNING.
EXTENSIVE TISSUE DAMAGE OR BURNS CAN RESULT FROM EXPOSURE TO LIQUID
NITROGEN OR COLD NITROGEN VAPORS.
Explanation of Carcinogenicity:NITROGEN IS A SIMPLE ASPHYXIANT AND HAS
NO THRESHOLD LIMIT VALUE.
Effects of Overexposure:OYXGEN DEFICIENT ATMOSPHERES MAY PRODUCE
DIZZINESS, NAUSEA, VOMITING, LOSS OF CONSCIOUSNESS AND DEATH.
NITROGEN UNDER HIGH PRESSURE CAN PRODUCE NARCOSIS EVEN THOUGH
OXYGEN SUFFICIENT FOR LIFE IS PRE SENT.

First Aid

First Aid:ASSISTED RESPIRATION/SUPPLEMENTAL OXYGEN SHOULD BE GIVEN IF
THE VICTIM IS NOT BREATHING. IF CRYOGENIC LIQ./COLD BOIL OFF GAS
CONTACTS A WORKER'S SKIN OR EYES,FROZEN TISSUES SHOULD BE
FLOODED/SOAKED W/TEPID WATER. DO NOT USE HOT WATER!!CRYOGENIC
BURNS WHICH RESULTS IN BLISTERING/DEEPER TISSUE FREEZING SHOULD BE
SEEN PROMPTLY BY A PHYSICIAN. MOVE PERSON TO A AREA WITH NORMAL
ATMOSPHERES.

Fire Fighting

Flash Point:NA
Lower Limits:NA
Upper Limits:NA
Extinguishing Media:NA
Fire Fighting Procedures:NA
Unusual Fire/Explosion Hazard:NA

Accidental Release

Spill Release Procedures:FLUSH LIQ NITROGEN SPILL W/WTR TO DISPERSE.
VENTL ENCLSD AREAS TO PREVENT FORMATION OF OXYGEN-DEFICIENT
ATMOSPHERES CAUSED BY THE EVAPORATION OF LIQ. NITROGEN OR THE
RELEASE OF GASEOUS NITROGEN. AVOID CONTACT OF SKIN W/LIQ
NITROGEN/COLD BOIL OFF GASES

Handling

Handling and Storage Precautions:USE A SUITABLE HAND TRUCK. AVOID
DRAGGING,ROLLING,SLIDNG OF CYLINDR.STORE OUTSIDE & PIPED TO THE
USEPOINT. KEEP CYLINDERS AWAY FROM SOURCES OF HEAT.
Other Precautions:IF LIQ CYLINDERS ARE TO BE STORED/TRANSPORTED IN AN
ENCLOSED AREA,IT'S ESSENTIALTHAT THE AREA BE WELL VENTILATED.
SEGREGATE FULL & EMPTY CYLINDERS. AVOID USE OF CARBON STEEL &
OTHER MATERIALS WHICH BECOME BRITTLE AT LOW TEMPERATURES.

Exposure Controls

Respiratory Protection:USE SELF-CONTAINED BREATHING APPARATUS IN OXYGEN
DEFICIENT ATMOSPHERES. CAUTION!! RESPIRATORS WILL NOT
FUNCTION. USE MAY RESULT IN ASPHYXIATION.
Ventilation:VENTS SHOULD BE SITUATED TO AVOID HIGHER THAN NORMAL
CONCENTRATION OF NITROGEN IN WORK AREA.
Protective Gloves:LOOSE GLOVES/IMPERMEABLE MATL LEATHER
Eye Protection:CHEMICAL GOGGLES/SAFETY GLASSES
Other Protective Equipment:NONE
Supplemental Safety and Health
LIQUID NITROGEN IS STORED IN VACUUM INSULATED CONTAINERS MEETING DOT
SPECIFICATIONS OR ASME CODES. IF OXYGEN DEFICIENT
ATMOSPHERES ARE SUSPECTED OR CAN OCCUR, USE OXYGEN MONITORING
EQUIPME NT TO TEST FOR OXYGEN DEFICIENTATMOSPHERES.
