Section III. Hazards Identification
    Acute Health Effects        Toxic if ingested or inhaled. 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. Avoid prolonged contact with this material. Overexposure may
    result in serious illness or death. Follow safe industrial hygiene practices and always wear proper protective equipment
    when handling this compound. 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.

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        Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If    
    breathing is difficult, administer oxygen. If the victim is not breathing, perform artificial respiration. WARNING: It may be
    dangerous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled material is toxic, infectious
    or corrosive. Seek immediate medical attention and, if possible, show the chemical label. 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.
