No further relevant information available.
· Indication of any immediate medical attention and special treatment needed
No further relevant information available.
Fire-fighting measures
· Extinguishing media
· Suitable extinguishing agents
Carbon dioxide (CO2, extinguishing powder or water spray/fog. Fight larger fires with water spray/fog or alcohol-resistant foam.
· For safety reasons unsuitable extinguishing agents
Water with a full water jet.
· Special hazards arising from the substance or mixture
Can be released in case of fire:
Hydrogen cyanide (HCN)
Nitrogen oxides (NOx)
Hydrogen chloride (HCl)
Formation of toxic gases is possible during heating or in case of fire.
· Advice for firefighters
· Protective equipment:
Wear self-contained breathing apparatus. Wear full protective suit.
· Additional information
Cool endangered containers with water spray jet. Dispose of fire debris and contaminated fire fighting water in accordance with official regulations.
Accidental release measures
· Personal precautions, protective equipment and emergency procedures
Wear protective clothing and keep away unprotected persons. Ensure adequate ventilation. Avoid causing dust. Avoid contact with skin and eyes. Remove all ignition sources.
· Environmental precautions:
Do not allow to enter drainage system, surface or ground water.
· Methods and material for containment and cleaning up:
Ensure adequate ventilation. Collect mechanically. Send for recovery or disposal in suitable containers. Dispose of the material collected according to regulations.
· Reference to other sections
See Section for information on personal protection equipment.
Handling and storage
· Precautions for safe handling
Ensure good ventilation/exhaustion at the workplace. Avoid contact with skin and eyes. Prevent formation of dust. Any deposit of dust which cannot be avoided must be removed regularly. Do not breathe dust. Make sure that all applicable workplace limits are observed.
· Information about protection against explosions and fires:
Keep ignition sources away - Do not smoke. Dust can combine with air to form an explosive mixture. Protect from heat. Use explosion-proof apparatus / fittings and spark-proof tools.
· Conditions for safe storage, including any incompatibilities
· Storage
· Requirements to be met by storerooms and containers:
Observe all local and national regulations for storage of water polluting products.
· Information about storage in one common storage facility:
Store away from foodstuffs. Store away from oxidizers. Do not store together with strong acids.
· Further information about storage conditions:
Protect from heat and direct sunlight. Do not seal container gastight. Store under dry conditions. Recommended storage temperature: < 40 °C
· Specific end use(s)
No further relevant information available.

Exposure controls / personal protection
· Control parameters
· Components with critical values that require monitoring at the workplace:
Observe all workplace limits for dust.
· Additional information:
The lists that were valid during the compilation were used as basis.
· Exposure controls
· Personal protective equipment
· General protective and hygienic measures
Keep away from foodstuffs, beverages and food. Do not eat, drink or smoke while working. Avoid contact with the eyes and skin. Do not inhale dust / smoke / mist. Immediately remove any clothing contaminated by the product. Wash hands during breaks and at the end of the work. Use skin protection cream for preventive skin protection.
· Breathing equipment:
Not necessary if room is well-ventilated. If all workplace limits are observed and good ventilation is ensured, no special precautions necessary.
· Protection of hands:
Protective gloves
Due to missing tests no recommendation to the glove material can be given for the product/ the preparation/ the chemical mixture.
To avoid skin problems reduce the wearing of gloves to the required minimum.
· Penetration time of glove material
Protective gloves should be replaced at first signs of wear. The exact break through time has to be found out by the manufacturer of the protective gloves and has to be observed.
· Eye protection:
Safety glasses
· Body protection:
Protective work clothing Body protection must be chosen depending on activity and possible exposure.
