Handling & PPE

Keep container tightly closed and dry. Store in a well-ventilated place. Recommended storage conditions: sealed, dry, room temperature
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).
Waste product. Dispose of remaining and non-recyclable solutions to a licensed company. Contact a professional organization with a waste disposal license to handle this substance. Dissolve or mix with flammable solvents and burn in a chemical incinerator with post-combustion and washing capabilities. Contaminated packaging. Dispose of as unused 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.
