Personal Precautions: Wear suitable chemical-resistant gloves, goggles, and protective clothing. Avoid breathing vapor or mist
Environmental Precautions: Prevent liquid from entering drains, sewers, or waterways; use barriers if needed
Cleanup Methods: Absorb on inert material such as sand or earth. Collect and place in containers for proper disposal. Flush residues with plenty of water after pickup
Spill Reporting: Notify environmental authorities if released in large quantities; follow local regulations
Precautions for Safe Handling: Prevent skin and eye contact. Do not inhale vapors. Use within well-ventilated areas. Avoid sources of ignition
Storage Requirements: Store tightly closed in a dry, cool, and well-ventilated space. Keep away from heat, flames, oxidizing agents, and direct sunlight. Use inert gas blanket for long-term storage to prevent polymerization
Incompatible Materials: Strong acids, strong bases, oxidizers, free radical initiators
Safe Transfer Methods: Ground and bond equipment; use static-free practices
