Methods for Cleaning Up: Sweep up spilled product, avoid raising dust, transfer to suitable container for disposal; clean area with water and ventilate
Additional Advice: Store any contaminated absorbent in clearly marked hazardous waste containers; do not flush undiluted product down drains
Safe Handling: Use adequate ventilation, minimize dust generation, wear gloves and eye protection, avoid prolonged or repeated contact
Hygiene Measures: Do not eat, drink or smoke when using; wash hands thoroughly afterward; remove contaminated clothing and wash before reuse
