Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide to extinguish fires involving this material
Unsuitable Extinguishing Media: None identified specific to this substance
Special Hazards: In case of fire, may release carbon oxides, nitrogen oxides, sodium oxides, and phosphorous oxides
Protective Equipment: Wear self-contained breathing apparatus and full protective clothing
Additional Advice: Contain runoff with barriers to avoid environmental release.
Personal Precautions: Avoid creating dust, ventilate area well, use personal protective equipment including gloves and goggles
Environmental Precautions: Prevent bulk quantities from entering water or drains
Spill Cleanup: Sweep up material and place into appropriate waste container, avoid raising dust, clean area with water after removal of material
Disposal: Dispose collected waste according to local, regional, and national regulations, do not flush large quantities to sewer.
Handling: Handle in a dry, well-ventilated area, minimize dust generation, avoid contact with eyes and prolonged skin exposure, wear gloves and eye protection if exposure likely
Storage: Store in tightly closed containers, place in a cool, dry, and well-ventilated area, keep away from incompatible materials such as strong oxidizing agents
Hygiene Measures: Wash hands and exposed skin before breaks and after work, do not eat, drink, or smoke around open product, label containers clearly and keep storage area clean.
Occupational Exposure Limits: No established limits found for this substance
Engineering Controls: Use local exhaust ventilation or process enclosure to reduce exposure to airborne particles
