*  Exposure Controls/Personal Protection  *
Respiratory Protection:USE RESPIRABLE FUME RESPIRATOR OR AIR SUPPLIED
    RESPIRATOR WHEN WELDING CONFINED SPACE OR WHERE LOCAL EXHAUST OR
    VENTILATION DOES NOT KEEP EXPOSURE BELOW TLV.
Ventilation:USE ENOUGH VENTILATION AND/OR LOCAL EXHAUST AT THE FLAME TO
    KEEP THE FUMES AND GASES BELOW TLV'S.
Other Protective Equipment:WEAR HAND, HEAD, AND BODY PROTECTION WHICH
    HELP TO PREVENT INJURY FROM RADIATION AND SPARKS.
Work Hygienic Practices:NONE SPECIFIED BY MANUFACTURER.

Health Hazards Acute and Chronic:ALTHOUGH THE INHALATION OF TUNGSTEN
    HAS THE POTENTIAL FOR CAUSING TRANSIENT OR PERMANENT LUNG DAMAGE,
    IT IS GENERALLY CONSIDERED TO EXHIBIT A LOW DEGREE OF TOXICITY.
    CONSIDERABLE EXPERIENCE IN REFININ G AND USE OF THORIUM HAS NOT HAS
    NOT REVEALED ANY ADVERSE EFFECTS FROM INDUSTRIAL EXPOSURE.
Effects of Overexposure:SHORT-TERM (ACUTE) OVEREXPOSURE TO WELDING
    FUMES MAY RESULT IN DISCOMFORT SUCH AS DIZZINESS, NAUSEA, OR
    DRYNESS OR IRRITATION OF THE NOSE, THROAT, OR EYES.  LONG-TERM
    (CHRONIC) OVEREXPOSURE TO WELDING  FUMES CAN LEAD TO SIDEROSIS
    (IRON IN LUNGS) AND AFFECT PULMONARY FUNCTION.
Medical Cond Aggravated by Exposure:ALLERGIC REACTION IS POSSIBLE IN
    SENSITIVE INDIVIDUALS; HOWEVER, SUCH REACTION CANNOT BE PREDICTED
    DUE TO VARIATION IN COMPOSITION AND QUANTITY OF THE DECOMPOSED
    PRODUCTS.
*  First Aid Measures  *
First Aid:CALL FOR MEDICAL AID. EMPLOY FIRST AID TECHNIQUES RECOMMENDED
    BY THE AMERICAN RED CROSS. IF BREATHING IS DIFFICULT, GIVE OXYGEN.
    CALL A PHYSICIAN. IN CASE OF ELECTRICAL SHOCK DISCONNECT AND TURN
    OFF P OWER. IF NOT BREATHING, BEGIN ARTIFICIAL RESPIRATION,
    PREFERABLY MOUTH-TO-MOUTH. IF NO DETECTABLE PULSE, BEGIN EXTERNAL
    HEART MASSAGE, IMMEDIATELY CALL A PHYSICIAN. FOR ARC BURN, CALL A
    PHYSICIAN.
*  Fire Fighting Measures  *
Flash Point:NON-FLAMMABLE
Extinguishing Media:AS APPROPRIATE FOR SURROUNDING FIRE.
