SECTION 5: Firefighting measures
Suitable extinguishing media
Use dry chemical, carbon dioxide or alcohol-resistant foam.
Specific hazards arising from the chemical
Flammable. Gives off irritating or toxic fumes (or gases) in a fire. Above 23°C explosive vapour/air mixtures may be formed.
Special protective actions for fire-fighters
Use foam, carbon dioxide, powder. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal protection: self-contained breathing apparatus. Collect leaking and spilled liquid in sealable containers as far as possible.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Above 23°C use a closed system, ventilation and explosion-proof electrical equipment. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof. Separated from oxidants and strong bases.
