First-aid measures
General Advice: When in doubt or if symptoms are observed, get medical advice. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
Eye Contact: In case of eye contact, remove contact lens and rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.
Skin Contact: Wash with plenty of soap and water.
Inhalation: Do not breathe dust. IF INHALED: Remove to fresh air and keep at rest in a position comfortable for breathing.
Ingestion: Rinse mouth thoroughly with water.
Aspiration hazard: Based on available data, the classification criteria are not met.
Notes to Physician: Treat symptomatically.
Personal Protective Equipment For First Aid Responders: Wear suitable protective clothing.
Most important symptoms and effects, both acute and delayed: Dust contact with the eyes can lead to mechanical irritation. Contact with dust can cause mechanical irritation or drying of the skin.
Indication of any immediate medical attention and special treatment needed: Treat symptomatically. Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and prevent spread of contamination.
Fire-fighting measures
Suitable Extinguishing Media: Use extinguishing agent suitable for type of surrounding fire. Water spray (fog). Dry chemical. Foam. Carbon dioxide (CO2).
Unsuitable Extinguishing Media: Do not use water jetstream.
Special hazards arising from the substance or mixture: Non-combustible.
Advice for firefighters
Special protective equipment for firefighters: Wear a self-contained breathing apparatus and chemical protective clothing.
Fire-fighting measures: Water mist may be used to cool closed containers.
Accidental release measures
Personal precautions, protective equipment and emergency procedures: Avoid dust formation. Ensure adequate ventilation. Use personal protection. Keep unauthorized personnel away.
For non-emergency personnel: Keep unauthorized personnel away.
For emergency responders: Keep unauthorized personnel away. Use personal protection recommended.
Environmental precautions: Avoid runoff to waterways and sewers.
Methods and material for containment and cleaning up: Large Spill: Do not dry sweep dust. Wet dust with water before sweeping or use a vacuum to collect dust Small Spill: Vacuum or sweep material and place in a disposal container
Handling and storage
Precautions for safe handling: Avoid exposure - obtain special instructions before use. Do not handle until all safety precautions have been read and understood. Minimize dust generation and accumulation. Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Use personal protective equipment as required.
Conditions for safe storage, including any incompatibilities: Keep container tightly closed and dry. Store away from incompatible materials.

Exposure controls / personal protection
Engineering Measures: Do not handle until all safety precautions have been read and understood. Ensure adequate ventilation, especially in confined areas. Provide a good standard of controlled ventilation (10 to 15 air changes per hour). Use exhaust ventilation to keep airborne concentrations below exposure limits. In case of insufficient ventilation, wear suitable respiratory equipment
Personal protective equipment
Eye/Face Protection: Wear safety glasses with side shields (or goggles).
Skin and Body Protection: Wear suitable protective clothing.
Hand protection: For operations where prolonged or repeated skin contact may occur, impervious gloves should be worn.
Respiratory Protection: When workers are facing concentrations above the exposure limit they must use appropriate certified respirators.
Thermal hazards: None known.
Hygiene Measures: No information available
Environmental Exposure Controls: Dispose of in accordance with local regulations
