First-aid measures after ingestion: Rinse mouth. Drink plenty of water. Keep victim under observation. Call a poison center or a doctor if you feel unwell.

Fire-fighting measures

Extinguishing media: Extinguish with dry sand. Water spray. Foam. Carbon dioxide (CO2).

Special hazards arising from the substance or mixture: Hazardous combustion products, Fire produces large volume of gases and toxic smoke.

Advice for firefighters: Protective equipment for fire-figthers, Self-contained breathing apparatus. Use air-supplied respirator, gloves and protective goggles.

Accidental release measures

Personal precautions: protective equipment and emergency procedures, avoid inhalation of dust, wear protective gloves and approved safety goggles.


 


Environmental precautions: Avoid release to the environment.


 


Methods and material for containment and cleaning up: Mechanically recover the product. Keep in suitable, closed containers for disposal. Notify authorities if product enters sewers or public waters. Avoid generation and spreading of dust. Sweep up the product. Dust production: dust mask with filter type P1.


 

Handling and storage

Precautions for safe handling: Ensure good ventilation of the work station. Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking. Wear personal protective equipment. Obtain special instructions before use. Do not handle until all safety precautions have been read and understood. Do not breathe dust. Avoid contact with skin and eyes.


 


Conditions for safe storage, including any incompatibilities: Store away from other materials. Store in a well-ventilated place. Keep cool. Keep only in original container. Store locked up. Protect from sunlight. Strong alkalis.
