=====================  Hazards Identification  =====================

Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Health Hazards Acute and Chronic:THE DEGREE OF INJURY WILL DEPEND ON
    THE AMOUNT OF MATL THAT GETS ON THE SKIN ANDTHE SPEED/THOROUGHNESS
    OF THE TREATMENT. BREATHING THE VAPORS AT CONCENTRATIONS ABOVE THE
    RECOMMENDED EXPOSURE STANDARD  CAN CAUSE CENTRAL NERVOUS SYSTEM
    EFFECTSASPIRATION OF LIQ INTO LUNGS BY VOMITING CAN CAUSE SEVERE
    INJURY TO LUNGS/DEATH
Effects of Overexposure:EYE:IRRITATION;  SKIN: PAIN OR FEELING
    HEAT,DISCOLORATION,SWELLING, & BLISTERINGINHAL: HEADACHES,
    DIZZINESS, LOSS OR APPETITE, WEAKNESS & LOSS OF CORDINATION.
