Section III. Hazards Identification
    Acute Health Effects        Corrosive to skin, eyes, and respiratory system. Liquid or spray mist may produce tissue damage, particularly in mucous
    membranes of the eyes, mouth and respiratory tract. Skin contact may produce burns. Eye contact can result in corneal
    damage or blindness. Inhalation of the spray mist may produce severe irritation of respiratory tract, characterized by
    coughing, choking, or shortness of breath. Corrosive materials may cause serious injury if ingested.
    Follow safe industrial hygiene practices and always wear proper protective equipment when handling this compound.
    Chronic Health Effects        CARCINOGENIC EFFECTS : Not available.
    MUTAGENIC EFFECTS : Not available.
    TERATOGENIC EFFECTS : Not available.
    DEVELOPMENTAL TOXICITY: Not available.
    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.

Section IV.        First Aid Measures
    Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15
    Eye Contact
    minutes. Get medical attention.
