4. First aid measures |
After inhalation: fresh air. If necessary, apply mouth-to-mouth resuscitation or mechanical ventilation. 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. Summon eye specialist. After swallowing: caution if victim vomits. Risk of aspiration! Keep airways free. Summon doctor. Subsequently administer: Paraffin oil (3 ml/kg). |
5. Fire-fighting measures |
Suitable extinguishing media: |
powder , CO2 , foam |
Special risks: |
Combustible. Vapours heavier than air. Formation of explosible mixtures possible with air. Keep away from sources of ignition. |
Other information: |
Take measures to prevent electrostatic charging. Beware of backfiring. |
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. |
7. Handling and storage |
Handling: |
Take measures to prevent electrostatic charging. |

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. |
