Section 6. ACCIDENTAL RELEASE MEASURES
  Personal precautions,        Use extra personal protective equipment (self-contained breathing apparatus). Keep    
  protective equipment and people away from and upwind of spill/leak. Ensure adequate ventilation. Entry to non-
  emergency procedures: involved personnel should be controlled 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 Do not allow contact with water. Remove all sources of ignition. Fire-extinguishing
  hazards:        devices should be prepared in case of a fire. Use spark-proof tools and explosion-    
    proof equipment.
