Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide
Special Hazards: Product may decompose to form oxides of carbon and sodium; dust in air can be combustible under rare, high-dust conditions
Precautions for Firefighters: Wear self-contained breathing apparatus and full protective gear; avoid inhaling combustion fumes
Explosion Data: Not sensitive to impact; avoid generating dust clouds in confined areas
Personal Precautions: Use gloves, eye protection, dust mask; ventilate area and minimize dust formation; avoid skin and eye contact
Methods for Cleanup: Sweep or vacuum up material into closed labeled containers; avoid generating airborne dust; wash spill area with water after removal
Environmental Precautions: Prevent large volumes entering drains or waterways; inform authorities if significant spillage occurs
Precautions for Safe Handling: Work in a well-ventilated space; do not breathe powder; wash hands thoroughly after handling; avoid contact with eyes, skin, and clothing
Storage Conditions: Store tightly sealed in original container in a cool, dry, and well-ventilated place, away from incompatible substances such as strong acids or bases; avoid sources of moisture and heat
Incompatibilities: Contact with strong oxidizers or bases can generate heat and cause degradation
Exposure Limits: No established threshold limit values available for this compound
Engineering Controls: Employ local exhaust or general ventilation for dusty work; use containment techniques with bulk handling
Personal Protective Equipment: Protective gloves (nitrile, neoprene), safety goggles or face shield, lab coat, dust mask for bulk handling; eyewash station and emergency shower accessible in the work area
