        【EC Class】flammable

        Physical and Chemical Properties
        【Solubility in water】Insoluble
        【Boiling Point】158 - 159
        【Density】0.925 g/cm3
        【Heat Of Vaporization】52.85 kJ/mol
        【Refractive Index】1.39 (20 C)

        First Aid Measures
        【Ingestion】Seek medical assistance.
        【Inhalation】Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
        【Skin】Remove and isolate contaminated clothing and shoes. Wash skin with soap and water. Flush with running water for at least 20 minutes
        【Eyes】Flush with running water for at least 20 minutes.

        Hazards Identification
        【Inhalation】May cause irritation or burns.
        【Skin】See Inhalation.
        【Eyes】See Inhalation.
        【Hazards】Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.
        【EC Risk Phrase】R 10
        【UN (DOT)】3272

        Exposure Controls/Personal Protection
        【Personal Protection】Wear appropriate protective gloves, clothing and goggles.
        【Respirators】Wear positive pressure self-contained breathing apparatus (SCBA).

        Fire Fighting Measures
        【Flash Point】52
        【Fire Fighting】Use of water spray when fighting fire may be inefficient. Small Fires: Dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Large Fires: Water spray, fog or alcohol-resistant foam. Use water spray or fog; do not use straight streams.
        【Fire Potential】HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.

        Accidental Release Measures
        【Small spills/leaks】Make no contact with the spilled material. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material.

        Stability and Reactivity
        【Disposal Code】1
        【Combustion Products】Fire may produce irritating, corrosive and/or toxic gases.

        Transport Information
        【UN Number】3272
        【HS Code】2920 90 10
