After contact with eyes: In case of contact with eyes rinse thoroughly with plenty of water. If symptoms persist, seek medical advice
After ingestion: When swallowed seek medical aid immediately and show the physician the packaging or the label of the packaging.
Fire-fighting measures
Suitable extinguishing media: water spray jet, foam
Special hazards from the substance itself, its combustion products or from its vapours:
In case of fires, hazardous combustion gases are formed: Carbon monoxide (CO), Nitrogen oxides (NOx)
Special protective equipment for firefighting: In case of fire, wear respiratory protection
Further information: Cool endangered containers with water spray jet.
Accidental release measures
Personal precautions: Use personal protective clothing. Keep away sources of ignition.
Environmental precautions: Do not allow entry to drains,water courses or soil
Methods for cleaning up/taking up:
Take up with suitable equipment and if necessary collect in closed containers. Clean contaminated floors and objects thoroughly, observing environmental regulations. Avoid raising dust
Handling and storage
Advice on safe handling: Avoid dust formation. Provide exhaust ventilation.
Advice on protection against fire and explosion: Keep away from sources of ignition. Take precautions against accumulation of electrostatic charge. Avoid deposition of dust.
Dust explosion class : ST2 Capable of dust explosion
Further information on storage conditions: Keep container tightly closed. Protect from heat

Exposure controls / personal protection
During its lifecycle the substance is handled under strictly controlled conditions and is rigorously contained in accordance Art. 18.
Based on the knowledge of the basic hazards to humans and environment technical, organizational and PPE measures are taken to minimize release and exposure of this substance. National regulatory requirements for the handling of chemicals are also fulfilled. Employees are regularly trained. The efficiency of these measures is controlled e.g. by workplace measurements. In case of deviations these measures are adapted.
General protective measures: Do not inhale dust. Avoid contact with eyes and skin
Hygiene measures: Keep away from foodstuffs and beverages.Wash hands before breaks and after work.
Respiratory protection : Dust mask
Hand protection :
Nitrile rubber gloves.Minimum breakthrough time (glove): not determined. Minimum thickness (glove): not determined
Observe the information of the glove manufacturers on permeability and breakthrough times and other workplace requirements
Eye protection : safety glasses/face shield
Body protection : working clothes
Stability and reactivity
Thermal decomposition : > 230 °C
Hazardous reactions: When handled and stored appropriately no dangerous reactions are known.
Hazardous decomposition products: When handled and stored appropriately, no dangerous decomposition products are known
Disposal considerations
Product: Special waste incineration plant, after consultation with operators
Uncleaned packaging: Packaging that cannot be cleaned should be disposed of as product waste
