Safety Information
Operating Requirements & Hazard Prevention
Perform all operations in locations with sufficient ventilation. To prevent skin contact, wear suitable protective gloves and full-coverage workwear. Prolonged or repeated skin exposure has the potential to induce allergic responses. Eye safety is of high importance—always utilize approved protective eyewear, such as safety glasses or chemical goggles, during product handling.
Actions to Take Following Exposure
Skin Exposure
Wash the involved skin area promptly using soap and water. Remove any soiled clothing and clean it before wearing again. If allergic signs develop, obtain medical evaluation.
Eye Exposure
Immediately rinse the eyes with water for a minimum of 15 minutes and contact a physician.
Ingestion
In case of swallowing, reach out to a physician without delay. Gastric suction or induced vomiting should be performed solely under medical supervision. Never administer anything orally to someone who is unconscious.
