  Precautions for firefighters: Fire-extinguishing work is done from the windward and the suitable fire-extinguishing
    method according to the surrounding situation is used. Uninvolved persons should
    evacuate to a safe place. In case of fire in the surroundings: Remove movable
    containers if safe to do so.
  Special protective        When extinguishing fire, be sure to wear personal protective equipment.
  equipment for firefighters:

Section 6. ACCIDENTAL RELEASE MEASURES
    Use personal protective equipment. Keep people away from and upwind of spill/leak.
  Personal precautions,
  protective equipment and Ensure adequate ventilation. Entry to non-involved personnel should be controlled
  emergency procedures: around the leakage area by roping off, etc.
  Environmental precautions: Prevent product from entering drains.
  Methods and materials for Absorb spilled material in a suitable absorbent (e.g. rag, dry sand, earth, saw-dust).
  containment and cleaning In case of large amount of spillage, contain a spill by bunding. Adhered or collected
  up: material should be promptly disposed of, in accordance with appropriate laws and
    regulations.
  Prevention of secondary Remove all sources of ignition. Fire-extinguishing devices should be prepared in
  hazards:        case of a fire. Use spark-proof tools and explosion-proof equipment.

Section 7. HANDLING AND STORAGE
