Hazards
Section 6. Accidental Release Measures
Small Spill Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by
spreading water on the contaminated surface and dispose of according to local and regional authority
requirements.
Large Spill Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading
water on the contaminated surface and allow to evacuate through the sanitary system.
Section 7. Handling and Storage
Precautions Keep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do
not ingest. Do not breathe dust. If ingested, seek medical advice immediately and show the container or
the label. Keep away from incompatibles such as oxidizing agents.
Storage Keep container tightly closed. Keep container in a cool, well-ventilated area. Do not store above 8°C
