Eye Contact: Flush eyes with plenty of water for at least 15 minutes. Remove contact lenses if easy to do. Seek medical attention for persistent irritation.
Skin Contact: Wash area thoroughly with soap and water. Remove contaminated clothing. Pay attention to any signs of redness or blistering.
Inhalation: Move person to fresh air. Check for breathing issues. Seek medical evaluation if symptoms appear.
Ingestion: Rinse mouth with water. Never give anything by mouth to an unconscious person. Do not induce vomiting unless instructed by medical professionals.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, do not use water jet directly on burning material
Fire Hazards: Dust can form explosive mixtures with air; combustion releases toxic fumes
Protective Equipment: Use self-contained breathing apparatus and protective clothing
Recommended Response: Evacuate area, stay upwind, contain runoff to prevent environmental contamination
Personal Precautions: Evacuate area, provide adequate ventilation, avoid dust formation
Environmental Precautions: Prevent from entering watercourses or soil
Methods of Cleanup: Use inert absorbent material, sweep up gently without creating dust clouds, collect in sealed containers for safe disposal
Handling: Avoid breathing dust or vapor, handle in well-ventilated areas, minimize exposure through skin or eyes
Hygiene: Wash hands after handling, keep work clothes separate, store contaminated clothing safely
Storage: Keep container tightly closed in a cool, dry place away from incompatible materials such as strong oxidizers or acids
Conditions to Avoid: Protect from direct sunlight, excessive heat, and sources of ignition
Engineering Controls: Local exhaust ventilation, chemical fume hood preferred
Personal Protective Equipment: Safety goggles, chemical-resistant gloves, long-sleeve laboratory coat or apron, appropriate respiratory protection if aerosol or dust is likely
Exposure Limits: No established regulatory exposure limits for this specific compound as of now
Physical State: Solid at room temperature
Color: Yellow to brown crystalline powder
Odor: Aromatic
Melting Point: Reported between 60-63°C
Solubility: Slight in water, soluble in common organic solvents like ethanol or chloroform
