Clean-Up Methods: Sweep or vacuum up spilled material, avoid generating dust, place in suitable labeled container for recovery or disposal, wash affected area with water
Handling: Wear gloves, goggles, and protective clothing, avoid contact with eyes, skin, and clothing, ensure areas are well ventilated, avoid inhaling dust, do not eat or drink near handling area
Storage: Store in a cool, dry, well-ventilated place, keep in tightly closed container, keep away from incompatible substances such as bases and oxidizing agents, protect from moisture, store away from food and drink
Exposure Limits: No specific occupational exposure limits established
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended guidelines
Personal Protective Equipment: Safety glasses with side-shields, gloves made from impervious material (e.g., nitrile), laboratory coat or coveralls, dust mask or respirator in case of dust formation
