Advice for fire-fighters:   Wear self-contained breathing apparatus. Wear fully protective impervious suit. 
Further information:   None. 
Section 6: Accidental   Release Measures 
Personal precautions, protective equipment and emergency procedures: 
Personal precautions:   Use proper personal protective equipment as indicated in Section 8. Avoid dust formation.
Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. 
Environmental precautions:   Prevent product from entering drains. Prevent further leakage or spillage if safe to do so.
Local authorities should be advised if significant spillages cannot be contained. 
Methods for containment and cleaning up: 
Methods for cleaning up:   Vacuum or sweep up material and place into a suitable disposal container. Clean up spills
immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Use a spark-
proof tool. Isolate area and deny entry. 
Reference to other sections:
