Section6. 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

Section7. 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.
Use a closed system if possible. Use a ventilation, local exhaust if vapour or aerosol
will be generated.
