    EXTINGUISHING MEDIA
    Suitable: For small (incipient) fires, use media such as
    "alcohol" foam, dry chemical, or carbon dioxide. For large
    ALDRICH        www.molbase.com    
    fires, apply water from as far as possible. Use very large
    quantities (flooding) of water applied as a mist or spray; solid
    streams of water may be ineffective. Cool all affected
    containers with flooding quantities of water.
    SPECIAL RISKS
    Specific Hazard(s): Emits toxic fumes under fire conditions.
    Vapor may travel considerable distance to source of ignition and
    flash back. Flammable liquid.
    Explosion Hazards: Vapor may travel considerable distance to
    source of ignition and flash back. Container explosion may occur
    under fire conditions.
    SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
    Wear self-contained breathing apparatus and protective clothing
    to prevent contact with skin and eyes.
    SPECIFIC METHOD(S) OF FIRE FIGHTING
    Keep down vapors with water spray.

    6 - Accidental Release Measures

---

    PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL
    Evacuate area. Shut off all sources of ignition.
    PROCEDURE(S) OF PERSONAL PRECAUTION(S)
    Wear self-contained breathing apparatus, rubber boots, and heavy
    rubber gloves.
    METHODS FOR CLEANING UP
    Cover with dry-lime, sand, or soda ash. Place in covered
    containers using non-sparking tools and transport outdoors.
    Ventilate area and wash spill site after material pickup is
    complete.
