Handling & PPE

  • Including any incompatibility. Close tightly. Dry. Store in a well-ventilated area. Recommended storage conditions: keep away from light, purge, 2-8°C
  • Avoid contact with skin and eyes. Avoid generating dust and aerosols. Provide appropriate ventilation in areas where dust is generated. General fire protection measures.
  • If exposed to a harmful environment, use a P95 (US) or P1 (EU UK 143) particulate respirator. For higher level of protection, use an OV/AG/P99 (US) or ABEK-P2 (EU UK 143) gas filter. Respirators must be tested and approved by government standards such as NIOSH (US) or CEN (EU).
  • The remaining and non-recyclable solutions should be handed over to a licensed company for disposal. Contact a professional agency with a waste disposal license to handle this substance. Dissolve or mix with flammable solvents and burn in a chemical incinerator with post-combustion and scrubbing. Contaminated packaging. Dispose of as unutilized product.

First Aid / Accidental Release

  • Do not give anything to an unconscious person. Rinse mouth with water. Consult a physician.
  • If inhaled, move the person to fresh air. If breathing stops, perform artificial respiration. Consult a physician.
  • Rinse with plenty of water for at least 15 minutes and consult a physician.
