Personal Protective Equipment: Firefighters should wear self-contained breathing apparatus and chemical protective clothing
Advice for Firefighters: Prevent fire-fighting water from contaminating drains or surface water, cool nearby containers to prevent rupture, evacuate area if extensive fire occurs
Personal Precautions: Wear gloves, eye protection, dust mask in case of powder, ventilate the area
Environmental Precautions: Prevent material from entering drains or watercourses
Methods for Cleanup: Collect spill with a non-sparking tool, sweep up and place in a properly labeled container for disposal, avoid raising dust, wash area with plenty of water
Emergency Procedures: Inform responsible authorities in case of large spill
Handling: Avoid breathing dust, avoid contact with skin, eyes, and clothing, use in a well-ventilated fume hood, keep away from incompatible substances such as strong bases and oxidizers, do not eat or drink near chemicals
Storage: Store tightly closed in a cool, dry, well-ventilated place, keep container upright to avoid leaks, protect from moisture, segregate from food and beverages, secure storage area from unauthorized access
Engineering Controls: Use local exhaust ventilation, maintain general workplace cleanliness, employ eyewash stations and emergency showers
