Section III. Hazards Identification
    Acute Health Effects        Irritating to eyes and skin on contact. Inhalation causes irritation of the lungs and respiratory system. Inflammation of the    
    eye is characterized by redness, watering, and itching. Skin inflammation is characterized by itching, scaling, reddening,
    or, occasionally, blistering. Follow safe industrial hygiene practices and always wear proper protective equipment when
    handling this compound.
    Chronic Health Effects        CARCINOGENIC EFFECTS : Not available.    
    MUTAGENIC EFFECTS : Positive chromosomal aberrations both in the presence and absence of s9 mix for
    phenol-2-[(4-hydroxyphenyl)sulfonyl].
    TERATOGENIC EFFECTS : Not available.
    DEVELOPMENTAL TOXICITY: Not available.
    There is no known effect from chronic exposure to this product. Repeated or prolonged exposure to this compound is
    not known to aggravate existing medical conditions.

Section IV.        First Aid Measures    
    Eye Contact        Check for and remove any contact lenses. IMMEDIATELY flush eyes with runing water for at least 15 minutes. keeping    
    eyelids open. COLD water may be used. DO NOT use an eye oitment. Flush eyes with running water for a minimum of
    15 minutes, occasionally lifting the upper eyelids. Seek medical attention. Treat symptomatically and supportively.
    Skin Contact        After contact with skin, wash immediately with plenty of water. Gently and thorough wash the contaminated skin with    
    running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. COLD water
    may be used. Cover the irritated skin with an emollient. Seek medical attention. Treat symptomatically and supportively.
    Wash any contaminated clothing before reusing.
    Inhalation        If the victim is not breathing, perform artificial respiration. Loosen tight clothing such as a collar, tie, belt or waistband. If    
    breathing is difficult, oxygen can be administered. Seek medical attention. Treat symptomatically and supportively.
    Ingestion        INDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.    
    Loosen tight clothing such as a collar, tie, belt, or waistband. If the victim is not breathing, administer artificial respiration.
    Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the toxic material
    was ingested; the absence of such signs, however, is not conclusive. Seek immediate medical attention and, if possible,
    show the chemical label. Treat symptomatically and supportively.

    Information
    breathe dust.
    Always store away from incompatible compounds such as oxidizing agents.

Section VIII. Exposure Controls/Personal Protection
    Engineering Controls        Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below    
    recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
    airborne contaminants below the exposure limit.
    Personal Protection        Splash goggles. Lab coat. Dust respirator. Boots. Gloves. Be sure to use a MSHA/NIOSH approved respirator or    
    equivalent. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.
    Exposure Limits        This chemical is classified as a possible carcinogen. There is no acceptable exposure limit for a carcinogen.
