Handling & PPE

  • Keep container tightly closed and dry. Store in a well-ventilated place. Recommended storage conditions: sealed, 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 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 washing functions if mixed with flammable solvents. Contaminated packaging. Dispose of as unutilized product.

First Aid / Accidental Release

  • Do not give anything by mouth 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.
  • 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 inhalation of vapors, mists or gases. Ensure adequate ventilation. Evacuate personnel to a safe area. Avoid inhalation of dust. See
  • 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 washing functions if mixed with flammable solvents. Contaminated packaging. Dispose of as unutilized product.

Firefighting / Stability

  • If necessary, wear a self-contained breathing apparatus for firefighting.
  • Reactivity
  • Carbon monoxide, carbon dioxide, nitrogen oxides
