Fire-fighting measures
Suitable extinguishing media:
Water mist, dry extinguishing media, foam, carbon dioxide (CO2)
Extinguishing media which must not be used for safety reasons:
For safety reasons do not use full water jet.
Specific Hazards:
Formation of harmful fumes. Hazardous combustion products: (CO, CO2).
Special protective equipment for fire-fighters:
Fire fighters should be equipped with self-contained breathing apparatus to prevent contact with reaction products.
Special protective equipment:
Do not stay in dangerous zone without self-contained breathing apparatus. In order to avoid contact
With skin, keep a safety distance and wear suitable protective clothing.
Further information:
Contaminated extinguishing water must be disposed of in accordance with local regulations.

Handling and storage
Handling:
Ensure thorough ventilation of stores and work areas. If handling large quantities without ventilation use respiratory protection.
Protection against fire and explosion:
Take precautionary measures against static discharge.
Storage:
Keep tightly sealed. Keep away from oxidising agents.
Protect against temperatures below 15°C. Protect against light.
Keep away from strong alkaline and strong oxidizing agents
