Hazardous Decomposition and/or Combustion

Products:
Carbon monoxide, Carbon dioxide, Organic products of
decomposition.
Risk of Dust Explosion: Dust may form explosive mixture in air. Take precautionary measures against static discharges.
6. ACCIDENTAL RELEASE MEASURES
Personal Precautions: Avoid dust cloud formation. Remove all sources of ignition. Ensure adequate
ventilation. Use personal protective equipment. See also Section 8.
Methods for Cleaning Up: Clean up promptly by vacuum. Use a suitable vacuum cleaner. Do not create a dust
cloud by using a brush or compressed air. Pick up and transfer to properly labelled containers. See Section 13.
Environmental Precautions: No special environmental precautions required. Local authorities should be advised if
significant spillages cannot be contained.
7. HANDLING AND STORAGE
Handling: Avoid dust cloud formation. Do not breathe dust. Provide appropriate exhaust ventilation at machinery and at places where dust can be generated. Do not create a
dust cloud by using a brush or compressed air. Avoid contact with skin and eyes.
Take precautionary measures against static discharge. All metal parts of the mixing
and processing equipment must be earthed/grounded. Ensure all equipment is
electrically earthed/grounded before beginning transfer operations.
Storage: Keep containers tightly closed in a dry, cool and well-ventilated place. Do not store together with volatile chemicals as they may be adsorbed onto product. Keep at
ambient temperatures. Heating above 300°C leads to decomposition of surface
treatment. Decomposition vapor should be ventilated.
