Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if easy to do, continue rinsing and get medical help if discomfort persists
Ingestion: Rinse mouth with water, do not induce vomiting, get immediate medical care if large amounts ingested
Potential Symptoms: Redness, itching, irritation to mucous membranes, headache if inhaled, nausea if swallowed
Suitable Extinguishing Media: Dry chemical, CO2, foam, water spray
Unsuitable Extinguishing Media: Direct water stream—may spread burning powder
Specific Hazards: May form toxic fumes of carbon monoxide and carbon dioxide during combustion
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Special Precautions: Cool containers exposed to flame with water spray from a safe distance, avoid inhalation of combustion products
Personal Protection: Use gloves, eye protection, dust mask or respirator, avoid creating airborne dust
Spill Containment: Sweep or shovel solids into a designated, labeled container—minimize dust generation
Environmental Precautions: Prevent releases to drains, surface water, and soil—report uncontrolled releases to authorities
Cleanup: Wash spill site with plenty of water after material pickup, ventilate area, dispose of waste materials according to local regulations
Handling Precautions: Avoid skin and eye contact, avoid breathing dust, use appropriate exhaust ventilation in work areas
Storage Conditions: Store in tightly closed container, in a cool, dry, well-ventilated location, away from direct sunlight and incompatible materials like strong oxidizers
Incompatibilities: Avoid contact with strong acids, bases, oxidizing agents
Hygiene Measures: Wash hands thoroughly after handling, remove and wash contaminated clothing before reuse, keep food and beverages away from work area
Control Parameters: Occupational exposure limits not established, though general dust limits may apply in some jurisdictions
Engineering Controls: Use local exhaust or general dilution ventilation—keep airborne concentrations below acceptable limits
Personal Protective Equipment: Safety goggles, chemical-resistant gloves, protective clothing, appropriate respirator under dusty conditions
Work Practices: Keep work area clean, use methods that minimize dust generation, wash thoroughly after handling
