Handling & PPE

  • Keep container tightly closed and dry. Store in a well-ventilated place. Recommended storage conditions: sealed, dry, room temperature
  • Avoid contact with skin and eyes. Avoid generating dust and aerosols. Provide appropriate ventilation in areas where dust is generated. General fire protection measures.
  • Use a P95 (US) or P1 (EU UK 143) particulate respirator if exposed to harmful environments. For higher level of protection, use OV/AG/P99 (US) or ABEK-P2 (EU UK 143) gas cartridges. Respirators must be tested and approved by government standards such as NIOSH (US) or CEN (EU).
  • Dispose of remaining and non-recyclable solutions to a licensed company. Contact a professional agency with waste disposal license to handle this substance. Burn in a chemical incinerator with post-combustion and scrubbing capabilities if mixed with flammable solvents. 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.
  • Wash with soap and plenty of water. Consult a physician.
  • Do not generate dust when collecting and disposing. Sweep and shovel up. Place in a suitable closed container for disposal.
  • Use personal protective equipment and emergency procedures. Avoid dust generation. Avoid inhaling vapors, mists or gases. Ensure adequate ventilation. Evacuate personnel to a safe area. Avoid inhaling dust. See
  • Do not allow the product to enter drains.
  • Dispose of remaining and non-recyclable solutions to a licensed company. Contact a professional agency with waste disposal license to handle this substance. Burn in a chemical incinerator with post-combustion and scrubbing capabilities if mixed with flammable solvents. Contaminated packaging. Dispose of as unutilized product.
