Inhalation: Move individual to fresh air, support breathing if irritation occurs, seek medical attention if symptoms persist or allergic reaction develops
Skin Contact: Wash area with soap and water, remove contaminated clothing, seek medical guidance if irritation erupts
Eye Contact: Rinse carefully with water or saline for several minutes, remove contact lenses, seek attention if redness or discomfort continues
Ingestion: Rinse mouth with water, drink water to dilute, do not induce vomiting, seek medical advice for significant ingestion or any unusual symptoms
Specific Advice for Healthcare Providers: Supportive care based on symptomatology, no specific antidote required
Suitable Extinguishing Media: Use water spray, dry chemical, CO2, or foam for extinguishing fires involving organic powder
Unsuitable Extinguishing Media: Avoid high-volume water jet that may spread dust
Special Hazards: Dust may form explosive mixtures with air in extreme conditions, combustion yields carbon oxides and nitrogen oxides
Protective Equipment for Firefighters: Wear full protective gear including mask with positive-pressure self-contained breathing apparatus
Additional Precautions: Prevent runoff from entering drains, isolate area, cool containers exposed to flames with water spray
Personal Precautions: Wear respiratory protection for dust, use gloves and goggles, avoid contact with eyes and skin
Environmental Precautions: Prevent material from entering watercourses, sewers, or soil, collect for proper disposal
Cleanup Methods: Contain spill with inert absorbent, sweep or vacuum up without generating dust, dispose of in compliance with local regulations
Emergency Procedures: Evacuate unnecessary personnel, ventilate area, report large spills to safety manager or local authorities if appropriate
Safe Handling: Work in a well-ventilated space, avoid dust generation, use personal protection for bulk handling, wash after handling
Storage Requirements: Store in tightly sealed container in a cool, dry place, away from direct sunlight and heat sources, segregate from incompatible substances such as strong oxidizers
Incompatibilities: Avoid mixing with strong acids, bases, or oxidizing agents
Storage Temperature: Preferred range between 15–25°C (59–77°F) for optimal shelf life
Additional Practices: Label containers clearly, monitor for clumping or discoloration which may signal deterioration
Occupational Exposure Limits: No established limits for this substance under OSHA, NIOSH, or ACGIH
Engineering Controls: General dilution ventilation, use of local exhaust for dust-producing operations, no open handling in confined spaces
