| 4. First aid measures |
|
After inhalation: fresh air. If necessary, apply mouth-to-mouth resuscitation or mechanical ventilation. Keep airways free. After skin contact: wash off with plenty of water. Remove contaminated clothing. After eye contact: rinse out with plenty of water with the eyelid held wide open. After swallowing: Avoid vomiting. Risk of aspiration! Subsequently administer: activated charcoal (20 - 40 g in 10% slurry). No milk. No castor oil. No alcohol. No gastric lavage. Summon doctor. |
| 5. Fire-fighting measures |
| Suitable extinguishing media: |
| Powder, foam. Fire extinguisher: powder , carbon dioxide |
|
Special risks: |
| Combustible. Vapours heavier than air. Formation of explosible mixtures possible with air. Keep away from sources of ignition. |
|
Special protective equipment for fire fighting: |
| Do not stay in dangerous zone without suitable chemical protection clothing and self-contained breathing apparatus. |
|
Other information: |
| Take measures to prevent electrostatic charging. |
| 6. Accidental release measures |
|
Person-related precautionary measures: Do not inhale vapours/aerosols. Ensure supply of fresh air in enclosed rooms. 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: |
| Take measures to prevent electrostatic charging. |
| Storage: |
| Tightly closed. In a well-ventilated place. Keep away from sources of ignition and heat. Storage temperature: no restrictions. |

| Specific control parameter | ||
| MAK Germany (max. workplace conc.) | ||
| n-Hexane | 50 ml/m3 or 180 mg/m3 | |
| Personal protective equipment: | |
| Respiratory protection: | required when vapours/aerosols are generated. Filter A (acc. to DIN 3181) for vapours of organic compounds |
| 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: | Immediately change contaminated clothing. Apply skin- protective barrier cream. Wash hands and face after working with substance. |

| 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. |
