Handling & PPE
- Use a P95 (US) or P1 (EU UK 143) particulate respirator if exposed to harmful environments. For higher level 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).
- 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 washing 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 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. 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. See
- 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.
