    CARCINOGENIC EFFECTS: Not available.
    Potential Chronic Health
    Effects        MUTAGENIC EFFECTS: Mutagenic for bacteria and/or yeast. [Ammonia, anhydrous].    
    TERATOGENIC EFFECTS: Not available.
    The substance is toxic to upper respiratory tract, skin, eyes.
    Repeated or prolonged exposure to the substance can produce target organs damage. Repeated or
    prolonged contact with spray mist may produce chronic eye irritation and severe skin irritation. Repeated or
    prolonged exposure to spray mist may produce respiratory tract irritation leading to frequent attacks of
    bronchial infection. Repeated exposure to a highly toxic material may produce general deterioration of health
    by an accumulation in one or many human organs.

Section 4. First Aid Measures
    Eye Contact        Check for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes,    
    keeping eyelids open. Cold water may be used. Get medical attention immediately. Finish by rinsing
    thoroughly with running water to avoid a possible infection.
    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 immediate    
    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 medical attention.
    Ingestion        If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by    
    mouth to an unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband. Get medical
    attention immediately.
