Health Hazards Acute and Chronic:THIS PRODUCT POSES NO HEALTH HAZARD AS
    SHIPPED BUT MAY POSE A HEALTH HAZARD DURING USE.  ELECTRIC ARC
    WELDING RAYS CAN INJURE EYES AND BURN SKIN. DUST, FUMES AND GASES
    CAN BE DANGEROUS TO YOUR HEALTH.  LUNG DAMAGE MAY RESULT FROM
    OVEREXPOSURE. SECTIONS (INGREDIENTS AND REACTIVITY) LIST SPECIFIC
    HAZARDOUS INGREDIENTS, REACTION PRODUCTS AND OSHA PEL'S AND ACGIH
    TLV'S.  PRIMARY ROUTE OF ENTRY: FUMES,  GASES AND DUST CAN BE A
    HEALTH HAZARD THRU INHALATION.  ACUTE EXPOSURE: SHORT TERM EXPOSURE
    TO WELDING FUMES, GASES OR DUST MAY RESULT IN DISCOMFORT SUCH AS

Effects of Overexposure:HEALTH HAZARDS ACUTE AND CHRONIC (CONT):
    IRRITATION OF NOSE, THROAT AND EYES. SKIN SENSITIVITY MAY ALSO BE
    NOTED. ACUTE EXPOSURE CAN RESULT IN THE SAME SYMPTOMS EXCEPT TO A
    GREATER DEGREE AS WELL AS W ATERY EYES, HEADACHE, BREATHING
    DIFFICULTY, FREQUENT COUGHING AND/OR CHEST PAINS. SOME TOXIC GASES
    MAY CAUSE PULMONARY EDEMA, ASPHYXIATION AND EXCESSIVE EXPOSURE CAN
    BE FATAL.  CHRONIC EXPOSURE: CHRON IC EXPOSURE MAY RESULT IN
    NEUROLOGICAL DAMAGE, LUNG FIBROSIS, PNEUMONCONIOSIS AND OTHER LUNG
