Handling & PPE

Use a P95 (US) or P1 (EU UK 143) particulate respirator if exposed to hazardous 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). 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. Burn contaminated packaging in a chemical incinerator with post-combustion and scrubbing 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.
Use personal protective equipment. Avoid dust generation. Avoid inhalation of vapors, mist or gas. Ensure adequate ventilation. Evacuate personnel to a safe area. Avoid inhalation of dust. See
