    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
