- Environmental precautions
- Not available.
- Methods and materials for containment and clean up
- Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions. Provide ventilation
7. Handling and Storage
- Precautions for safe handling
- Wash thoroughly after handling. Use with adequate ventilation. Keep container tightly closed. Do not get on skin or in eyes. Wash clothing before reuse. Avoid breathing dust.
- Conditions for safe storage
- Store in a tightly closed container. Keep from contact with oxidising materials. Store in a cool, dry, well-ventilated area away from incompatible substances
