Hazards

Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:NITROGEN IS ODORLESS AND NONTOXIC, BUT
MAY PRODUCE SUFFOCATION BY DILUTING THE CONCENTRATION OF OXYGEN IN
AIR BELOW LEVELS NECESSARY TO SUPPORT LIFE. PERSONS,INCLUDING
RESCUE WORKERS, SHOULD NOT ENT ER AREAS WHERE THE OXYGEN
CONCENTRATIONIS BELOW 19%, UNLESS PROVIDED WITH A SELF-CONTAINED
BREATHING APPARATUS.
Explanation of Carcinogenicity:NITROGEN IS A SIMPLE ASPHYXIANT AND HAS
NO THRESHOLD LIMIT VALUE (TLV).
Effects of Overexposure:EXPOSURE TO OXYGEN-DEFICIENT ATMOSPHERE MAY
PRODUCE DIZZINESS, NAUSEA, VOMITING,LOSS OF CONSCIOUSNESS, & DEATH.
EXTENSIVE TISSUE DAMAGE OR BURNS CAN RESULT FROEXPOSURE TO LIQUID
NITROGEN OR COLD NITR OGEN VAPORS.NITROGEN UNDER HIGH PRESSURECAN
PRODUCE NARCOSIS EVEN THOUGH OXYGEN SUFFICIENT FOR LIFE IS PRESENT.
Medical Cond Aggravated by Exposure:NITROGEN UNDER HIGH PRESSURE CAN
PRODUCE NARCOSIS EVEN THOUGH OXYGEN SUFFICIENT FOR LIFE IS
PRESENT.RESPIRATORS WON'T FUNCTION IN OXY-DEFICIENT ATMOS.& USE MAY
RESULT IN ASPHYXIATION. USE S.C.B.A.

First Aid

First Aid:MOVE PERSON SUFFERING FROM LACK OF OXY TO NORMAL ATMOS. IF
PERSON IS NOT BREATHIPERFORM CPR AND PROVIDE SUPPLEMENTAL OXY. IF
CRYOGENIC LIQ OR COLD BOIL-OFF GAS CONTACTS A WORKER'S SKIN OR
EYES,FROZEN TISSUES SHOULD BE FLOODED OR SOAKED WITHTEPID WATER.
DO NOT USE HOT WATER. CRYOGENIC BURNS WHICH RESULT IN BLISTERING
OR DEEPER TISSUE FREEZING SHOULD BE SEEN PROMPTLY BY A PHYSICIAN.

Accidental Release

Spill Release Procedures:AVOID CONTACT OF SKIN WITH LIQUID NITROGEN OR
ITS BOIL-OFF GAS. FLUSH LIQ NITROGEN SPILL WITH WATERTO DISPERSE.
VENT ENCLOSED AREAS TO PREVENT FORMA-TION OF OXY-DEFICIENT ATMOS.
CAUSED BY THE EVAP OF LIQUID NITROGEN OR THE RELEASE OF GASEOUS
NITROGEN

Handling

Handling and Storage Precautions:PREVENT ENTRAPMENT OF LIQ IN CLOSED
SYS. SEGREGATEFULL & EMPTY CYLINDERS.PREVENT CONTACT OF LIQ NIT OR
COLD BOIL-OFF GAS WITH SKIN. SEE CGA PAMP P-1.
Other Precautions:LIQUID NITROGEN IS A CRYOGENIC LIQ. MATERIALS OF
CONSTRUCTION MUST BE SELECTED FOR COMPATIBILITY WITH EXTREMELY LOW
TEMPS. AVOID USE OF CARBON STEEL & OTHER MATERIALS WHICH BECOME
BRITTLE AT LOW TE MPERATURES.

Exposure Controls

Respiratory Protection:USE SELF-CONTAINED BREATHING APPARATUS IN
OXYGEN-DEFICIENT ATMOSPHERES. CAUTION! RESPIRATORS WILL
NOT FUNCTION. USE MAY RESULT IN ASPHYXIATION.
Ventilation:NATURAL OR MECHANICAL WHERE GAS IS PRESENT.
Protective Gloves:LEATHER WORK GLOVES
Eye Protection:CHEMICAL GOGGLES OR SAFETY GLASSES
Other Protective Equipment:NONE
Supplemental Safety and Health
VENTS SHOULD BE SITUATED TO AVOID HIGHER THAN NORMAL CONCENTRATION OF
NITROGEN IN WORK AREAS.

Disposal

Waste Disposal Methods:ALLOW LIQ NITROGEN TO EVAP IN WELL VENTILATED
OUT-DOOR LOCATION REMOTE FROM WORK AREAS. VENT NIT-GASIN SAME WAY.
DO NOT DISPOSE OF RESIDUAL NITROGEN IN COMPRESSED GAS CYLINDERS.
