    4 - First Aid Measures

    AFTER INHALATION
    If inhaled, remove to fresh air. If not breathing give
    artificial respiration. If breathing is difficult, give oxygen.
    AFTER SKIN CONTACT
    In case of skin contact, flush with copious amounts of water for
    at least 15 minutes. Remove contaminated clothing and shoes.
    Call a physician.
    AFTER EYE CONTACT
    In case of contact with eyes, flush with copious amounts of
    water for at least 15 minutes. Assure adequate flushing by
    separating the eyelids with fingers. Call a physician.
    AFTER INGESTION
    If swallowed, wash out mouth with water provided person is
    conscious. Call a physician.

    5 - Fire Fighting Measures

    ALDRICH        www.molbase.com    
    EXTINGUISHING MEDIA
    Suitable: Carbon dioxide, dry chemical powder, or appropriate
    foam. Water spray.
    SPECIAL RISKS
    Specific Hazard(s): Emits toxic fumes under fire conditions.
    SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
    Wear self-contained breathing apparatus and protective clothing
    to prevent contact with skin and eyes.

    6 - Accidental Release Measures

    PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL
    Evacuate area.
    PROCEDURE(S) OF PERSONAL PRECAUTION(S)
    Wear self-contained breathing apparatus, rubber boots, and heavy
    rubber gloves.
    METHODS FOR CLEANING UP
    Absorb on sand or vermiculite and place in closed containers for
    disposal. Ventilate area and wash spill site after material
    pickup is complete.

    7 - Handling and Storage

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

    8 - Exposure Controls / Personal Protection

    ENGINEERING CONTROLS
    Safety shower and eye bath. Mechanical exhaust required.
    GENERAL HYGIENE MEASURES
    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.
