Section 6. ACCIDENTAL RELEASE MEASURES
  Personal precautions,        Use personal protective equipment. Keep people away from and upwind of spill/leak.
  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 dry sand or inert absorbent before recovering it into an
  containment and cleaning airtight container. In case of large amount of spillage, contain a spill by bunding.
  up: Adhered or collected 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
  Precautions for safe handling
  Technical measures:        Handling is performed in a well ventilated place. Wear suitable protective equipment.
    Prevent generation of vapour or mist. Keep away from heat/sparks/open flame/hot
    surfaces. -No smoking. Take measures to prevent the build up of electrostatic
    charge. Use explosion-proof equipment. Wash hands and face thoroughly after
    handling.
