Section III. Hazards Identification
    Corrosive to skin, eyes, and respiratory system. Liquid or spray mist may produce tissue damage, particularly in mucous
    Acute Health Effects
    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.
    CARCINOGENIC EFFECTS : Not available.
    Chronic Health Effects
    MUTAGENIC EFFECTS : Not available.
    TERATOGENIC EFFECTS : Not available.
    DEVELOPMENTAL TOXICITY: Not available.
    Repeated exposure of the eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce local
    skin destruction, or dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung
    damage.

Section IV.        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.
    Skin Contact        In case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing    
    before reuse. Thoroughly clean shoes before reuse. Get medical attention.
    If the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or
    Inhalation
    waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
    improve.
    DO NOT INDUCE VOMITING. Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing,
    Ingestion
    perform mouth-to-mouth resuscitation. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible
    indication that the toxic material was ingested; the absence of such signs, however, is not conclusive.

    vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all sources of ignition. Consult
    federal, state, and/or local authorities for assistance on disposal.

Section VII. Handling and Storage
    Handling and Storage        CORROSIVE. MOISTURE SENSITIVE. MAY DEVELOP PRESSURE. STORE UNDER ARGON. Keep container dry. Keep    
    away from heat. Mechanical exhaust required. When not in use, tightly seal the container and store in a dry, cool place.
    Information
    Avoid excessive heat and light. Do not breathe dust. Never add water to this product. Wear suitable protective clothing. If
    you feel unwell, seek medical attention and show the label when possible. Treat symptomatically and supportively.
    Always store away from incompatible compounds such as oxidizing agents, alkalis (bases), moisture.

Section VIII. Exposure Controls/Personal Protection
    Engineering Controls        Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended    
    exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants
    below the exposure limit.
    Personal Protection        Face shield. Lab coat. Dust respirator. Boots. Gloves. A MSHA/NIOSH approved respirator must be used to avoid    
    inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this
