Hazardous Combustion Products: Possible formation of toluene derivatives, oxides of carbon, unknown toxic vapors
Personal Precautions: Use approved respirator if ventilation is not adequate, avoid creating airborne dust, wear gloves and eye protection
Environmental Precautions: Prevent further leakage or spillage if safe to do so, avoid release into surface/groundwater
Cleanup Methods: Scoop up bulk solids into suitable container for disposal, use gentle sweeping/vacuuming, do not use dry sweeping for large spills, ventilate area
Decontamination: After removal of solid, clean surface with detergent solution, rinse thoroughly to minimize residue
Disposal of Cleanup Materials: Dispose contaminated material as hazardous waste according to local regulations
Handling Precautions: Handle with gloves, avoid contact with eyes, skin, and clothing, keep dust levels low, ensure air movement in area, avoid breathing powders
Safe Handling Advice: Open containers slowly and carefully, use in chemical fume hood or ventilated space, always wash hands before breaks, after handling
Storage Requirements: Store in original tightly-closed container, in cool and dry location, keep away from incompatible substances (bases, oxidizers), avoid direct sunlight
Incompatibilities: Avoid contact with amines, strong bases, and strong oxidizing agents
Special Precautions: Secure container to prevent tipping, segregate from food and animal feed
Specific End Use(s): Laboratory reagent, chiral separation — not for household or food use
