Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital.

1. Confirm identity
Match the supplier specification, CAS/EC identifiers and composition to this official label name. Similar wording is not proof of chemical equivalence.
2. Review restrictions
Check every exact Annex record shown above, plus CMR, nanomaterial, SCCS and later-amendment requirements that may apply.
3. Verify the formula
Evaluate concentration, product type, purity, warnings, claims and each target market before making a compliance decision.
