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.
    Toxic if ingested or inhaled. Avoid prolonged contact with this material. Overexposure may result in serious illness or death.
    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 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 an highly toxic material may produce general deterioration of health by an accumulation in one or
    many human organs.

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 for at least 15 minutes while removing contaminated clothing    
    and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
    Inhalation        If the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or    
    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.

Section VI.        Accidental Release Measures    
    Spill Cleanup        Corrosive material. Toxic material. Hygroscopic material. Air sensitive material.    
    Stop leak if without risk. If the product is in its solid form: Use a shovel to put the material into a convenient waste disposal
    Instructions
    container. If the product is in its liquid form: Absorb with DRY earth, sand or other non-combustible material. DO NOT get
    water inside container. Absorb with an inert material and put the spilled material in an appropriate waste disposal. DO NOT
    touch spilled material. Use water spray curtain to divert vapor drift. Use water spray to reduce 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.
