Section 3. Hazards Identification
    Potential Acute Health Effects        Very hazardous in case of skin contact (irritant), of eye contact (irritant). Hazardous in case of ingestion, of    
    inhalation. Slightly hazardous in case of skin contact (corrosive, permeator), of eye contact (corrosive). The
    amount of tissue damage depends on length of contact. Eye contact can result in corneal damage or
    blindness. Skin contact can produce inflammation and blistering. Inhalation of dust will produce irritation to
    gastro-intestinal or respiratory tract, characterized by burning, sneezing and coughing. Severe over-exposure
    can produce lung damage, choking, unconsciousness or 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        Hazardous in case of skin contact (irritant).    
    Effects        CARCINOGENIC EFFECTS: Not available.    
    MUTAGENIC EFFECTS: Not available.
    TERATOGENIC EFFECTS: Not available.
    DEVELOPMENTAL TOXICITY: Not available.
    The substance may be toxic to mucous membranes, upper respiratory tract, skin, eyes.
    Repeated or prolonged exposure to the substance can produce target organs damage. 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.
