Section 4. First Aid Measures
    Eye Contact        Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water    
    for at least 15 minutes. Cold water may be used. Get medical attention immediately.
    Skin Contact        In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing    
    contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash
    clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
    Serious Skin Contact        Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical    
    attention.
    Inhalation        If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.    
    Get medical attention immediately.
    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. WARNING: It may be hazardous to the person providing aid to give mouth-to-mouth
    resuscitation when the inhaled material is toxic, infectious or corrosive. Seek immediate medical attention.
    Ingestion        Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to    
    an unconscious person. If large quantities of this material are swallowed, call a physician immediately.
    Loosen tight clothing such as a collar, tie, belt or waistband.
