Other information: |
|
Take measures to prevent electrostatic charging. Prevent fire-fighting water from entering surface water or groundwater. |
| 6. Accidental release measures |
|
Person-related precautionary measures: Do not inhale vapours/aerosols. Avoid substance contact. Procedures for cleaning / absorption: Take up with liquid-absorbent material (e.g. Chemizorb® ). Forward for disposal. Clean up affected area. Environmental-protection measures: Do not allow to enter sewerage system; risk of explosion! |
| 7. Handling and storage |
| Handling: |
| No further requirements. |
| Storage: |
| Tightly closed. In a well-ventilated place. Keep away from sources of ignition and heat. At +15°C to +25°C. Accessible only for authorized persons. |
| 8. Exposure controls/personal protection |
| Personal protective equipment: | |
| Respiratory protection: | required when vapours/aerosols are generated. |
| Eye protection: | required |
| Hand protection: |
required Protective clothing should be selected specifically for the working place, depending on concentration and quantity of the hazardous substances handled. The resistance of the protective clothing to chemicals should be ascertained with the respective supplier. |
| Industrial hygiene: | Change contaminated clothing. Application of skin- protective barrier cream recommended. Wash hands after working with substance. Under no circumstances eat or drink at workplace. |

| 13. Disposal considerations |
| Product: |
| There are no uniform EC Regulations for the disposal of chemicals or residues. Chemical residues generally count as special waste. The disposal of the latter is regulated in the EC member countries through corresponding laws and regulations. We recommend that you contact either the authorities in charge or approved waste disposal companies which will advise you on how to dispose of special waste. |
| Packaging: |
| Disposal in compliance with official regulations. Handle contaminated packaging in the same way as the substance itself. If not officially specified differently, non-contaminated packaging may be treated like household waste or recycled. |
