    HAZARD HAS BEEN RECOGNIZED.  INGESTION EFFECTS: NONE KNOWN. 
    INGESTION IS UNLIKELY AS PRODUCT IS A GAS AT ROOM TEMPERATURE. 
    INHALATION EFFECTS: INHALATION CA USES BREATHING DIFFICULTIES,
    CHEST PAINS AND NAUSEA.  IT FORMS A HEMOGLOBIN COMPLEX, SIMILAR TO
    CARBON MONOXIDE, AND THUS, IS HIGHLY POISONOUS DUE TO INTERFERENCE
    WITH OXYGEN TRANSPORT IN BLOOD.  EFFE CTS OF OXYGEN DEFICIENCY
    RESULTING FROM SIMPLE ASPHYXIANTS MAY INCLUDE: RAPID BREATHING,
    DIMINISHED MENTAL ALERTNESS, IMPAIRED MUSCULAR COORDINATION, FAULTY
    JUDGEMENT, AND  DEPRESSION OF ALL SENSATION S.

=======================  First Aid Measures  =======================

Eyes: NONE NORMALLY REQUIRED.  SKIN: NONE NORMALLY REQUIRED. 
    INGESTION: NONE NORMALLY REQUIRED.	INHALATION: PROMPT MEDICAL
    ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE.  RESCUE
    PERSONNEL SHOU LD BE EQUIPPED WITH SELF-CONTAINED BREATHING
    APPARATUS.	VICTIMS SHOULD BE ASSISTED TO AN UNCONTAMINATED AREA
    AND INHALE FRESH AIR.  QUICK REMOVAL FROM THE CONTAMINATED AREA IS
    MOST IMPORTANT.  UNCONS CIOUS PERSONS SHOULD BE MOVED TO AN
    UNCONTAMINATED AREA AND, IF BREATHING HAS STOPPED, ADMINISTER
    ARTIFICIAL RESUSCITATION AND SUPPLEMENTAL OXYGEN.  FURTHER
    TREATMENT SHOULD BE SYMPTOMATIC AND SUPPORT IVE.

=====================  Fire Fighting Measures  =====================

Flash Point:NONE
Autoignition Temp:Autoignition Temp Text:NONE
Lower Limits:NONE
Upper Limits:NONE
Extinguishing Media:USE ANY EXTINGUISHING MEDIA WHICH IS SUITABLE FOR
    THE SURROUNDING FIRE.
Fire Fighting Procedures:FIRES SUPPORTED BY NITROGEN TRIFLUORIDE AS THE
    OXIDIZER GENERATE TOXIC FLUORIDE COMPOUNDS.
Unusual Fire/Explosion Hazard:NONFLAMMABLE GAS.  HOWEVER, IT MAY FORM
    FLAMMABLE OR EXPLOSIVE MIXTURES WITH GASEOUS FUELS.  ABOVE 1830 F,
    IT SHOULD IGNITE MOST MATERIALS ON CONTACT.

==================  Accidental Release Measures  ==================

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA. 
    USE APPROPRIATE PROTECTIVE EQUIPMENT.  IF LEAK IS IN USER'S
    EQUIPMENT, BE CERTAIN TO PURGE PIPING WITH INERT GAS PRIOR TO
    ATTEMPTING REPAIRS.  IF LEAK IS IN	CONTAINER OR CONTAINER VALVE,
    CONTACT CHEMTREC: 800-424-9300.

======================	Handling and Storage  ======================

Handling and Storage Precautions:MOST METALS ARE SATISFACTORY FOR
    HANDLING NITROGEN TRIFLUORIDE UP TO TEMPERATURES OF APPROXIMATELY
    160 F.  NICKEL AND MONEL ARE RECOMMENDED FOR HIGHER TEMPERATURES. 
    WETTED SURFACES SHOULD BE PASSIVAT ED WITH AN "ACTIVE" FLUORINE
    COMPOUND TO ESTABLISH A METAL FLUORIDE COATING AS ADDITIONAL
    PROTECTION
Other Precautions:KEEP EQUIPMENT SCRUPULOUSLY DRY.  MANY OF THE METAL
    FLUORIDES ARE WATER SOLUBLE SO THAT THE PASSIVE FILM CORROSION
    PROTECTION MAY BE DESTROYED IF WETTED WITH WATER.  USE ONLY IN
    WELL-VENTILATED AREAS.   VALVE PROTECTION CAPS MUST REMAIN IN PLACE
    UNLESS CONTAINER IS SECURED WITH VALVE PROTECTION OUTLE T PIPED TO
    USE POINT

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:POSITIVE PRESSURE AIR LINE WITH FULL-FACE MASK
    AND ESCAPE BOTTLE OR SELF-CONTAINED BREATHING APPARATUS SHOULD BE
    AVAILABLE FOR EMERGENCY USE.
Ventilation:HOOD WITH FORCED VENTILATION.  LOCAL EXHAUST.  TO PREVENT
    ACCUMULATION ABOVE THE EXPOSURE LIMIT.
Protective Gloves:PLASTIC OR RUBBER GLOVES.
Eye Protection:SAFETY GOGGLES OR GLASSES.
Other Protective Equipment:SAFETY SHOES.
Supplemental Safety and Health
DON'T DRAG, SLIDE, ROLL, OR HEAT CYLINDERS. USE CHECK VALVE OR TRAP IN
    DISCHARGE LINE TO PREVENT BACK FLOW. STORE UPRIGHT & FIRMLY
    SECURED. USE FIRST-IN FIRST-OUT INVENTORY SYSTEM.

    IMPART A MUSTY OR PUNGENT ODOR

=================  Stability and Reactivity Data  =================

Stability Indicator/Materials to Avoid:YES

    RELATIVELY INERT TOWARD MOST MATERIALS.  INCOMPATIBLE WITH
    PLASTICS, HYDROCARBONS AND OTHER ORGANIC MATERIALS.

===================  Toxicological Information	===================

Toxicological Information:MUTAGENIC: AMES TESTS CONDUCTED ON NITROGEN
    TRIFLUORIDE ARE REPORTED AS NEGATIVE, WITHOUT METABOLIC
    ACTIVATION;WEAKLY POSITIVE, WITH METABOLIC ACTIVATION.  EXAMINATION
    OF THESE RESULTS AND THOSE OF PR EVIOUSLY CONDUCTED TESTS SUGGESTS
    THATTHE ACTIVITY SHOWN IS ATTRIBUTABLE TO N2F2, A RECOGNIZED
    CONTAMINANT OF NF3.  NF3 IS CURRENTLY MANUFACTORED WITH A MINIMAL
    N2F2 CONTENT.  THE TOXICITY OF NF3 IS R ELATED TO ITS CAPACITY TO
    FORM METHEMOGLOBIN, A MODIFIED FORM OF HEMOGLOBIN INCAPABLE OF
    TRANSPORTING OXYGEN, AND ITS ABILITY TO DESTROY RED BLOOD CELLS. 
    UPON CESSATION OF EXPOSURE, METHEMOGLOBIN SPO NTANEOUSLY REVERTS TO
    HEMOGLOBIN.

    UNUSED QUANTITIES.	RETURN IN THE SHIPPING CONTAINER PROPERLY
    LABELED, WITH ANY VALVE OUTLET PLUGS OR CAPS SECURED AND VALVE
    PROTECTION CAP IN PLACE TO A DVANCED SPECIALTY GASES FOR PROPER
    DISPOSAL.
