ACGIH TLV: ASPHYXIANT; 9192

LD50 LC50 Mixture:TLV: NONE ESTABLISHED.
Routes of Entry: Inhalation:YES Skin:YES Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:NRTROGEN IS NONTOXIC, BUT MAY PRODUCE
SUFFOCATION BY DISPLACING THE OXYGEN IN THE AIR. EXPOSURE TO
OXYGEN- DEFICIENT ATMOSPHERES MAY CAUSE DIZZINESS, NAUSEA,
VOMITING, DIMINISHED MENTAL ALERTNESS, LOS S OF CINSCIOUSNESS &
DEATH.
Explanation of Carcinogenicity:NOT LISTED BY IARC, NTP OR OSHA.
Effects of Overexposure:PROLONGED BREATHING OF VERY COLD ATMOSPHERES
CAN CAUSE LUNG DAMAGE & HYPOTHERMIA. FROZEN TISSUES, CAUSED BY
FROSTBITE ARE PAINLESS & APPEAR WAXY WITH A POSSIBLE YELLOW COLOR.
THEY WILL BECOME SWOLLEN, APINFUL, & PRONE TO INFECTION.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

First Aid:PERSONS SUFFERING FROM LACK OF OXYGEN SHOULD BE MOVED INTO
FRESH AIR. IF NOT BREATHING, ADMINISTER ARTIFICIAL RESPIRATION. IF
BREATHING IS DIFFICULT, ADMINISTER OXYGEN. IF CONTACT WITH LIQUID
HAS CAUS ED FROSTBITE, DO NOT RUB AREA, AS TISSUE DAMAGE MAY OCCUR.
FLUSH AFFECTED AREA WITH WARM WATER. OBTAIN PROMPT MEDICAL
ATTENTION IN BOTH CAESES. (SELF-CONTAINED BREATHING APPARATUS MAY
BE NEEDED)

Extinguishing Media:MATERIAL IS NONFLAMMABLE. NITROGEN NEITHER
BURNS/SUPPORTS COMBUSTION. USE MEDIA APPROPIATE FOR SURROUNDING
FIRE.
Fire Fighting Procedures:NONE. NITROGEN WILL ACT AS A SIMPLE ASPHYXIANT
IT WILL DISPLACE OXYGEN.
Unusual Fire/Explosion Hazard:CONTACT WITH "COLD" LIQUID OR GASEOUS
NITROGEN MAY CAUSE FROSTBITE. VISIBILITY MAY BE DESCURED IN THIS
"VAPOR CLOUD".

Spill Release Procedures:SHUT OFF NITROGEN SOURCE IF POSSIBLE. AVOID
CONTACT WITH LIQUID NITROGEN OR ITS BOIL-OFF GAS. TO INCREASE RATE
OF EVAPORATION SPRAY WITH LARGE AMOUNTS OF WATER FROM UPWIND. IF
LEAKING FROM CONTAINER C ONTACT THE CLOSEST BIG THREE INDUSTRY.

Handling and Storage Precautions:STORE & USE WITH ADEQUATE VENTILATION.
CONTAINERS SHOULD BE STORED UPRIGHT & FIRMLY SECURED TO PREVENT
FALLING OR BEING KNOCKED OVER.
Other Precautions:DEPLETION OF OXYGEN CONTENT IN AIR BY DISPLACEMENT
WITH INERT GAS IS A POTENTIAL HAZARD. SAFE WORKING ATMOSPHERE IS
CONSIDER TO BE 20.9% OXYGEN.

Respiratory Protection:USE SELF-CONTAINED BREATHING APPARATUS IN
OXYGEN- DEFICIENT ATMOSPHERES. RESPIRATORS WILL NOT FUNCTION.
Ventilation:LOCAL EXHAUST: YES. MECHANICAL: YES.
Protective Gloves:LOOSE FITTING THERMAL INSULATED/LEATHER
Eye Protection:FULL FACE SHIELD & SAFETY GLASSES.
Other Protective Equipment:LONGSLEEVED SHIRT FOR LIQUID HANDLING.
SAFETY SHOESIF HANDLING CYLINDERS.
Work Hygienic Practices:NONE SPECIFIED BY MANUFACTURER.
Supplemental Safety and Health
NITROGEN IS NON-TOXIC BUT CAN ACT AS AN ASPHYXIANT BY DISPLACING THE
NECESSARY AMOUNT OF AIR TO SUSTAIN LIFE.
