Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray
Specific Hazards: May release harmful vapors such as carbon monoxide under fire conditions
Protective Equipment for Firefighters: Self-contained breathing apparatus and full protective gear
Special Procedures: Avoid breathing dust or fumes, use water spray to cool containers exposed to fire
Personal Precautions: Wear protective equipment, keep unprotected persons away, avoid inhalation and direct skin contact
Environmental Precautions: Stop material entering drains or water courses
Methods for Cleanup: Scoop up solid and place into sealable container for disposal, wipe small spills with damp cloth, ventilate area, wash site after removal
Handling: Use in well-ventilated area, avoid generating dust, keep away from food and beverages, wash hands before eating or drinking
Storage Conditions: Store in tightly closed container, in a cool dry place, keep away from incompatible substances such as oxidizers
Incompatible Materials: Strong oxidizing agents
Special Rules: Only trained personnel should handle bulk material
Exposure Limits: No established occupational exposure limits
