Handling & PPE
- Closed. Dry. Store in a well-ventilated area. Recommended storage conditions: Sealed and dry, room temperature
- 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 and parts must be tested and approved by government standards such as NIOSH (US) or CEN (EU).
- The remaining and non-recyclable solution should be handed over to a licensed company for disposal. Contact a professional institution with a waste disposal license to handle this substance. Combust the contaminated packaging in a chemical incinerator with post-combustion treatment and scrubbing capabilities, provided it is soluble or mixed with flammable solvents. Contaminated packaging should be disposed of as unused product.
First Aid / Accidental Release
- Do not give anything to an unconscious person. Rinse mouth with water. Consult a doctor.
- If inhaled, move the patient to fresh air. If breathing stops, perform artificial respiration. Consult a doctor.
- Rinse with plenty of water for at least 15 minutes and consult a doctor.
- Wash with soap and plenty of water. Consult a doctor.
