First-aid measures
Description of first aid measures
General information: In case of accident or if you feel unwell, seek medical advice immediately.
After inhalation: Supply fresh air. After inhalation of dust or powder seek medical advice.
After skin contact: Immediately wash with water and soap and rinse thoroughly. If skin irritation continues, consult a doctor.
After eye contact: Rinse opened eye for several minutes under running water. Then consult a doctor. Seek medical treatment.
After swallowing: Rinse out mouth and then drink plenty of water. If symptoms persist consult doctor.
Most important symptoms and effects, both acute and delayed: 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: CO2, powder or water spray. Fight larger fires with water spray or alcohol resistant foam.
Special hazards arising from the substance or mixture: Fine sized metal shows catalytic effects and can accelerate combustion processes. Keep away from
combustible material.
Advice for firefighters
Protective equipment: Wear self-contained respiratory protective device. Wear fully protective suit.
Accidental release measures
Personal precautions, protective equipment and emergency procedures:
Wear protective equipment. Keep unprotected persons away.
Avoid formation of dust.
Environmental precautions: Do not allow to enter sewers/ surface or ground water. Do not allow to penetrate the ground/soil.
Methods and material for containment and cleaning up: Pick up mechanically. Send for recovery or disposal in suitable receptacles.
Reference to other sections:
See Section 7 for information on safe handling.
See Section 8 for information on personal protection equipment.
See Section 13 for disposal information.
