|
After inhalation: fresh air. If necessary, apply mouth-to-mouth resuscitation or mechanical ventilation. After skin contact: wash off with plenty of water. Dab with polyethylene glycol 400. Immediately remove contaminated clothing. Immediately summon doctor. After eye contact: rinse out with plenty of water for at least 10 minutes with the eyelid held wide open. Immediately summon eye specialist. |
| 5. Fire-fighting measures |
| Suitable extinguishing media: |
| powder , CO2 Cool containers with water. |
|
Special risks: |
|
Combustible. Development of hazardous combustion gases or vapours possible in the event of fire. Vapours heavier than air. Formation of explosive mixtures possible with air. Keep away from sources of ignition. In the event of decomposition: danger of explosion! The following may develop in event of fire: carbon monoxide |
|
Special protective equipment for fire fighting: |
