    7 - Handling and Storage

---

    HANDLING
    Directions for Safe Handling: Do not get in eyes, on skin, on
    clothing. Do not breathe vapor. Avoid prolonged or repeated
    exposure.
    STORAGE
    Conditions of Storage: Keep tightly closed.

---

    8 - Exposure Controls / Personal Protection

---

    ENGINEERING CONTROLS
    Safety shower and eye bath. Use only in a chemical fume hood.
    GENERAL HYGIENE MEASURES
    Wash contaminated clothing before reuse. Wash thoroughly after
    handling.
    PERSONAL PROTECTIVE EQUIPMENT
    Respiratory Protection: Use respirators and components tested and
    approved under appropriate government standards such as NIOSH (US)
    or CEN (EU). Where risk assessment shows air-purifying respirators
    are appropriate use a full-face respirator with multi-purpose
    combination (US) or type ABEK (EN 14387) respirator cartridges as
    a backup to engineering controls. If the respirator is the sole
    means of protection, use a full-face supplied air respirator.
    Hand Protection: Compatible chemical-resistant gloves.
    Eye Protection: Chemical safety goggles.

    SIGNS AND SYMPTOMS OF EXPOSURE
    To the best of our knowledge, the chemical, physical, and
    toxicological properties have not been thoroughly investigated.
    In contrast to inorganic mercury compounds, alkyl mercury
    compounds rapidly pass through the placenta and blood brain
    barrier. The peripheral and central nervous systems and the
    kidney are major target organs. Methylmercury poisoning symptoms
    result primarily from damage to the nervous system. The symptoms
    are primarily characterized by loss of sensation in the hands
    and feet and in areas around the mouth, diminution of vision
    resulting in tunnel vision, ataxia, dysarthria, and hearing
    loss. Severe poisoning produces blindness, coma and death. There
    is a latent period of weeks to months before development of the
    poisoning symptoms. Mercury shows a specificity to damage small
    nerve cells in the cerebellum and visual cortex. Methylmercury
    causes degeneration and necrosis of neurons in the focal areas
    of the cerebral cortex, especially within the visual areas of
    the occipital cortex and the granular layer of the cerebellum.
    It has been found that methylmercury inhibits protein synthesis
    in the brain before symptoms of poisoning appear and that
    ALDRICH        www.molbase.com    
    recovery of protein synthesis does not occur in granular cells
    as it does recover in other neuronal cell types. Consumption by
    pregnant women has caused serious neurological disorders in
    their offspring resulting in mental retardation with cerebral
    palsy. Acute exposure to nonlethal levels of methylmercyry
    results in
    ROUTE OF EXPOSURE
    Skin Contact: Causes skin irritation.
    Skin Absorption: Readily absorbed through skin. May be fatal if
    absorbed through skin.
    Eye Contact: Causes eye irritation.
    Inhalation: Material is irritating to mucous membranes and upper
    respiratory tract. May be fatal if inhaled.
    Ingestion: May be fatal if swallowed.
    TARGET ORGAN INFORMATION
    Kidneys. Nerves.
    CONDITIONS AGGRAVATED BY EXPOSURE
    May cause nervous system disturbances.
