- If exposed to a harmful environment, use a P95 (US) or P1 (EU UK 143) particulate respirator. 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).
- The remaining product and non-recyclable solutions should be handed over to a licensed company for disposal. Contact a professional institution 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 person to fresh air. If breathing stops, perform artificial respiration. Consult a physician.
