Handling & PPE

Keep container tightly closed and dry. Store in a well-ventilated place. Recommended storage conditions: nitrogen-purged, room temperature
If exposed to a harmful environment, use a P95 (US) or P1 (EU, UK 143) particulate respirator. For higher level 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).
Waste product: 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 in a chemical incinerator with post-combustion treatment and washing if soluble or mixed with flammable solvents. Burn contaminated packaging. Dispose of contaminated packaging 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.
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 the sewer.
