Handling & PPE

Keep container tightly closed and dry. Store in a well-ventilated place. Recommended storage conditions: light-protected, inerted, 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 solutions should be handed over to a licensed company for disposal. Contact a professional organization with a waste disposal license to handle this substance. Burn contaminated packaging in a chemical incinerator with post-combustion and washing functions. Contaminated packaging should 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 the patient 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. For personal protection, see
Do not allow the product to enter drains.
