Section 3. Hazards Identification
    Potential Acute Health Effects Extremely hazardous in case of ingestion. Very hazardous in case of skin contact (irritant, sensitizer, permeator),
    of eye contact (irritant), of inhalation. Non-corrosive for skin. Severe over-exposure can result in death.
    Inflammation of the eye is characterized by redness, watering, and itching. Skin inflammation is characterized by
    itching, scaling, reddening, or, occasionally, blistering.
    Potential Chronic Health        Extremely hazardous in case of ingestion.    
    Effects        Very hazardous in case of skin contact (sensitizer, permeator), of eye contact (irritant), of inhalation.    
    CARCINOGENIC EFFECTS: Classified A5 (Not suspected for human.) by ACGIH.
    MUTAGENIC EFFECTS: Not available.
    TERATOGENIC EFFECTS: Not available.
    The substance is toxic to kidneys, the nervous system.
    Repeated or prolonged exposure to the substance can produce target organs damage. Repeated exposure to a
    Ammoniated mercury
    highly toxic material may produce general deterioration of health by an accumulation in one or many human

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. 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. 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.
    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        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.
    Serious Ingestion        Not available.

Section 7. Handling and Storage
    Precautions        Keep locked up.. Do not ingest. Do not breathe dust. In case of insufficient ventilation, wear suitable respiratory    
    equipment. If ingested, seek medical advice immediately and show the container or the label. Avoid contact with
    skin and eyes. Keep away from incompatibles such as oxidizing agents, alkalis.
    Storage        Keep container tightly closed. Keep container in a cool, well-ventilated area.    

Section 8. Exposure Controls/Personal Protection
