Clean-up Methods: Absorb with inert absorbent (sand, vermiculite); collect and dispose in proper containers; flush residuals with copious water
Reporting: Notify authorities as required by regulations for environmental release
Handling Precautions: Use in a well-ventilated space; ground/bond equipment during transfer; avoid breathing vapors and contact with skin or eyes
Storage Conditions: Keep containers tightly closed in cool, dry, well-ventilated area; store away from heat, flames, and incompatible materials such as oxidizers
Requirements: Spill containment, no smoking zones, regular inspection of containers
Transfer Advice: Use proper transfer equipment to avoid splashing or static accumulation
