Section 3. Hazards Identification
    Potential Acute Health Effects Extremely hazardous in case of skin contact (irritant), of eye contact (irritant). Very hazardous in case of
    ingestion, of inhalation (lung irritant). Hazardous in case of skin contact (corrosive). Prolonged exposure may
    result in skin burns and ulcerations. Over-exposure by inhalation may cause respiratory irritation. Inflammation of
    the eye is characterized by redness, watering, and itching. Skin inflammation is characterized by itching, scaling,
    reddening, or, occasionally, blistering.

Section 4. First Aid Measures
    Eye Contact        Check for and remove any contact lenses. Do not use an eye ointment. Seek medical attention.    
    Skin Contact        If the chemical got onto the clothed portion of the body, remove the contaminated clothes as quickly as possible,    
    protecting your own hands and body. Place the victim under a deluge shower. If the chemical got on the victim's
    exposed skin, such as the hands : Gently and thoroughly wash the contaminated skin with running water and
    non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. If irritation persists, seek
    medical attention. Wash contaminated clothing before reusing.
    Serious Skin Contact        Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical    
    Allow the victim to rest in a well ventilated area. Seek immediate medical attention.
    Serious 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 mouth-to-mouth
    resuscitation. Seek medical attention.
    Ingestion        Do not induce vomiting. Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not    
    breathing, perform mouth-to-mouth resuscitation. Seek immediate medical attention.
