Handling & PPE

  • Use a P95 (US) or P1 (EU UK 143) particulate respirator if exposed to hazardous environments. 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). Do not allow the product to enter drains.
  • Dispose of remaining and non-recyclable solutions to a licensed company. Contact a professional agency with a waste disposal license to handle this substance. Burn contaminated packaging in a chemical incinerator with post-combustion and scrubbing capabilities. Contaminated packaging is to be disposed 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 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.
  • Use personal protective equipment. Avoid dust generation. Avoid inhalation of vapors, mist or gas. Ensure adequate ventilation. Evacuate personnel to a safe area. Avoid inhalation of dust. See
