============= Composition/Information on Ingredients =============
Name:NITROGEN
CAS:7727-37-9
RTECS #:QW9700000
Fraction by Wt: >99%
ACGIH TLV:ASPHYXIANT
===================== Hazards Identification =====================
Routes of Entry: Inhalation:YES Skin:YES Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:LIQUID NITROGEN CAN CAUSE RAPID
SUFFOCATION WHEN CONCENTRATIONS ARE SUFFICIENT TO REDUCE OXYGEN
LEVELS BELOW 19.5%. CONTACT W/LIQUID/COLD VAPORS CAN CAUSE SEVERE
FROSTBITE. INHALATION: SIMPLE ASPHYXIA NT. EYES/SKIN: TISSUE
FREEZING & SEVERECRYOGENIC BURNS.
Explanation of Carcinogenicity:NONE
Effects of Overexposure:DIZZINESS, DROWSINESS, NAUSEA, VOMITING, EXCESS
SALIVATION, DIMINISHED MENTAL ALERTNESS, LOSS OF CONSCIOUSNESS,
DEATH. SKIN CONTACT W/LIQUID NITROGEN: TISSUE FREEZING, BURNS, RED
W/FORMATION OF BLISTE RS.
Medical Cond Aggravated by Exposure:NONE
======================= First Aid Measures =======================
First Aid:INHALATION: REMOVE TO FRESH AIR. GIVE CPR/OXYGEN IF NEEDED.
SKIN: DON'T RUB FROZEN PARTS AS TISSUE DAMAGE MAY RESULT. PLACE IN
WARM WATER BATH AT TEMP NOT EXCEEDING 105F. NEVER USE DRY HEAT. IF
FROZEN PART OF BODY HAS BEEN THAWED, COVER W/DRY STERILE DRESSING
W/LARGE BULKY PROTECTIVE COVERING, PENDING MEDICAL CARE. EYES: WARM
FROSTBITE W/WARM WATER. OBTAIN MEDICAL ATTENTION IN ALL CASES.
===================== Fire Fighting Measures =====================
Extinguishing Media:USE MEDIA APPROPRIATE FOR SURROUNDING AREAS.
Fire Fighting Procedures:SIMPLE ASPHYXIANT. REMOVE CONTAINERS W/COOL
WATER. DON'T DIRECT WATER SPRAY AT THE CONTAINER VENT. WEAR SCBA.
EVACUATE ARA.
Unusual Fire/Explosion Hazard:LIQUID NITROGEN WHEN SPILLED WILL
VAPORIZE RAPIDLY FORMING AN OXYGEN DEFICIENT VAPOR CLOUD. PRESSURE
CAN BUILD UP DUE TO HEAT & RUPTURE. (SEE SUPP)
================== Accidental Release Measures ==================
Spill Release Procedures:EVACUATE AREA. INCREASE VENTILATION & MONITOR
OXYGEN LEVEL. USE PROTECTIVE EQUIPMENT. TO INCREASE RATE OF
VAPORIZATION, SPRAY LARGE AMOUNTS OF WATER FROM UPWIND POSITION.
DON'T SPRAY WATER DIRECTLY AT LEAK. IN USER SYSTEM, CLOSE CYLINDER
VALVE/VENT.
====================== Handling and Storage ======================
Handling and Storage Precautions:USE ADEQUATE VENTILATION. DON'T STORE
IN CONFINED SPACE. DON'T PLUG, REMOVE/TAMPER W/PRESSURE RELIEF
DEVICE. NEVER TOUCH UNINSULATED PIPES/VESSELS.
Other Precautions:HANDLE/STORE IN UPRIGHT POSITION. DON'T DROP,
TIP/ROLL CONTAINERS ON THEIR SIDES. DON'T REMOVE/INTERCHANGE
CONNECTIONS. USE PROPER CONNECTIONS. DON'T USE ADAPTERS. USE
PIPING/EQUIPMENT DESIGNED TO W/S TAND PRESSURE.
============= Exposure Controls/Personal Protection =============
Respiratory Protection:SCBA/POSITIVE PRESSURE AIRLINE W/MASK & ESCAPE
PACK ARE TO BE USED IN OXYGEN DEFICIENT ATMOSPHERE. RESPIRATORS
WILL NOT FUNCTION.
Ventilation:MECHANICAL: TO PREVENT OXYGEN DEFICIENT ATMOSPHERES <19%
OXYGEN.
Protective Gloves:LOOSE FITTING THERMAL INSULATED/LEATHER
Eye Protection:FULL FACE SHIELD/SAFETY GLASSES
Other Protective Equipment:SAFETY SHOES, LONG SLEEVE SHIRTS & TROUSERS
W/O CUFFS.
Work Hygienic Practices:REMOVE ANY CLOTHING THAT MAY RESTRICT
CIRCULATION TO FROZEN AREA.
Supplemental Safety and Health
UNUSUAL FIRE CONT'D: CONTACT W/COLD LIQUID/GASEOUS OXYGEN MAY CAUSE
FROSTBITE. SPILLS CONT'D: IF LEAK, CLOSE CYLINDER VALVE & VENT
PRESSURE BEFORE ATTEMPTING REPAIRS. USE CHECK VALVE/PROTECTIVE
APPARA TUS IN ANY LINE/PIPING FROM CYLINDER TOPREVENT REVERSE FLOW.
