RTECS #:QW9700000
ACGIH TLV:ASPHYXIANT; 9192
===================== Hazards Identification =====================
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 A SIMPLE ASPHYXIANT &
CONSTITUTES 78% OF THE AIR WE BREATHE.NITROGENDOES NTO SUPPORT LIFE
& MAY PRODUCE IMMEDIATE HAZARDOUS ATMOS THROUGH THE DISPLACEMENT OF
OXY.NITROGEN UNDER HIGH PRESSU RE CAN PRODUCE NARCOSIS EVEN THOUGH
OXYGEN SUFFICIENT FOR LIFE IS PRESENT.
Effects of Overexposure:MAY PRODUCE DIZZINESS,NAUSEA,VOMITING,LOSS OF
CONSCIOUSNESS,&DEATH.DEATH MAY RESULT FROM ERRORS IN
JUDGEMENT,CONFUSION,OR LOSS OF CONSCIOUSNESS WHICH PREVENTS
SELF-RESCUE.AT LOW OXYGEN CONCENTRATIONS UNCONSCIOUSNESS & DEATH
MAY OCCUR W/OUTWARNING.EXTENSIVE TISSUE DAMAGE OR BURNS CAN RESULT
FROM LIQ NIT OR COLD NIT VAP
======================= First Aid Measures =======================
First Aid:CONSCIOUS/UNCONSCIOUS PERSON ASSISTED TO NORMAL ATMOS.IF
NECESSARY GIVE ASSISTEDRESPIRATION & SUPPLEMENTAL OXY.IF CRYOGENIC
LIQ OR COLD BOIL-OFF CONTACTS SKIN/ EYES,FROZEN TISSUE SHOULD BE
FLOODED OR SOAKED W/TEPID WTR(105-115F;41-46C).DONOT USE HOT
WTR.CRYOGENIC BURNS WHICH RESULT IN BLISTERING OR DEEPER TISSUE
FREEZING SHOULD BE SEEN PROMPTLY BY A PHYSICIAN.

Fire Fighting Procedures:NA
Unusual Fire/Explosion Hazard:NA
================== Accidental Release Measures ==================
Spill Release Procedures:AVOID CONTACT OF SKIN W/LIQ NITROGEN OR ITS
COLD BOIL-OFF GAS.FLUSH LIQ NIT SPILL W/WTR TO DISPERSE.VENT
ENCLOSED AREAS TO PREVENT FORMATION OF OXY-DEFICIENT ATMOS CAUSED
BY THE EVAPORATION OF LIQ NIT ROGEN OR THE RELEASE OF GASEOUS
NITROGEN.
====================== Handling and Storage ======================
Handling and Storage Precautions:USE/STORE IN WELL VENT AREA.DO NOT
DRAG,ROLL OR SLIDE CYLS.USE SUITABLE HAND TRUCK.KEEP CYLS AWAY FROM
SOURCES OF HEAT.SEGREGATE FULL/EMPTY CYLS.
Other Precautions:LIQ NIT IS A CRYOGENIC LIQ.MATERIALS OF CONSTRUCTION
MUST BE SELECTED FOR COMPATIBILITY W/EXTREMELY LOW TEMPS.AVOID USE
OF CARBON STEEL & OTHER MATERIALS WHICH BECOME BRITTLE AT LOW
TEMPS.
============= Exposure Controls/Personal Protection =============
Respiratory Protection:USE SELF-CONTAINED BREATHING APPARATUS IN
OXYGEN-DEFICIENT ATMOSPHERE.CAUTION!RESPIRATORS WILL NOT
FUNCTION.USE MAY REULT IN ASPHYXIATION.
Ventilation:NATURAL OR MECHANICAL WHERE GAS IS PRESENT.
Protective Gloves:LOOSE-FITTING IMPERMEABLE (LEATHER)
Eye Protection:CHEMICAL GOGGLES/SAFETY GLASSES
Other Protective Equipment:NONE
