Section 7. Handling and Storage
    Precautions        Do not breathe dust. Keep away from incompatibles such as oxidizing agents.    
    Storage        Keep container tightly closed. Keep container in a cool, well-ventilated area. Air Sensitive    

Section 8. 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        Safety glasses. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent. Gloves.    
    Personal Protection in Case of Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
    a Large Spill        to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist    
    BEFORE handling this product.

    Chronic Effects on Humans
    Special Remarks on other        Potential Health Effects:    
    Toxic Effects on Humans        Skin: May cause skin irritation. May cause contact dermatitis.    
    Eyes: May cause eye irritation. May cause conjunctivitis in sensitive individuals.
    Inhalation: Can cause respiratory tract irritation. Inhalation can also trigger the onset of hypersensivity reactions,
    nasal pruritus(itiching) and rhinorrhea (runny nose in sensitized individuals.
    Ingestion: When ingested it can cause gastric irritation by liberation of sulfurous acid. Because of rapid oxidation
    to sulfate, sulfites are well tolerated until large doses are reached. Ingestion of large doses can cause nausea,
    vomiting, abdominal pain, violet colic and diarrhea. It may also cause circulatory disturbances, hypotension (low
    blood pressure), and may affect behavior/central nervous system (central nervous system stimulation followed by
    depression, seizures). In animals, hypotension, cyanosis, and cardiovascular collapse have been described
    following ingestion of lethal doses of sulfites. Some asthmatics are said to be dangerously sensitive to minute
    amounts of sulfites in foods. Symptoms of hypersensitivity are bronchoconstriction, swelling of the tongue,
    diffuculty swallowing, diaphoresis (sweating), flushing, urticaria (hives), tachycardia (rapid heart beat),
    hypotension, and anaphylaxis.
