Handling & PPE

  • Sealed. Dry. Store in a well-ventilated area. Recommended storage conditions: Sealed and dry, room temperature
  • Use a P95 (US) or P1 (EU UK 143) particulate respirator if exposed to harmful environments. For higher level of protection, use an OV/AG/P99 (US) or ABEK-P2 (EU UK 143) gas filter. Respirators and parts must be tested and approved by government standards such as NIOSH (US) or CEN (EU).
  • The remaining and non-recyclable solution should be handed over to a licensed company for disposal. Contact a professional institution with a waste disposal license to handle this substance. Combust the contaminated packaging in a chemical incinerator with post-combustion treatment and washing functions. Contaminated packaging should be disposed of as unused product.

First Aid / Accidental Release

  • Do not give anything to an unconscious person. Rinse mouth with water. Consult a doctor.
  • If inhaled, move the person to fresh air. If breathing stops, perform artificial respiration. Consult a doctor.
  • Rinse with plenty of water for at least 15 minutes and consult a doctor.
  • Wash with soap and plenty of water. Consult a doctor.
  • Do not generate dust when collecting and disposing. Sweep and shovel up. Place in a suitable closed container for disposal.
  • Use personal protective equipment. Avoid dust generation. Avoid inhalation of vapors, mists or gases. Ensure adequate ventilation. Evacuate personnel to a safe area. Avoid inhalation of dust. See
  • Do not allow the product to enter drains.
  • The remaining and non-recyclable solution should be handed over to a licensed company for disposal. Contact a professional institution with a waste disposal license to handle this substance. Combust the contaminated packaging in a chemical incinerator with post-combustion treatment and washing functions. Contaminated packaging should be disposed of as unused product.
