Spill Response: Remove ignition sources, absorb liquid spill with inert absorbent (sand, vermiculite), collect in suitable containers for disposal
Decontamination: Clean area with plenty of water after removal
Special Instructions: Use only non-sparking tools, contain spill from spreading, do not walk through spilled material
Handling: Use only in well-ventilated areas, avoid breathing vapors or mist, avoid contact with skin or eyes, ground and bond all containers, keep away from heat or open flame
Storage Conditions: Store in tightly closed, properly labeled, corrosion-resistant containers, in a cool, dry, well-ventilated place, protected from direct sunlight and moisture
Temperature Control: Maintain below 30°C, install inhibitors/stabilizers in prolonged storage
Incompatible Materials: Strong acids, bases, oxidizing agents, reducing agents, iron, copper, polymerization initiators
Special Handling Advice: Monitor for peroxides, use explosion-proof equipment, rotate stock regularly to prevent aging
