Specific Hazards: Product easily ignites, vapors may travel to source of ignition and flashback, thermal decomposition releases acrid smoke, carbon monoxide, carbon dioxide, toxic fumes
Special Protective Equipment: Self-contained breathing apparatus and flame-retardant protective clothing
Firefighting Advice: Cool drums with water from a safe distance, contain runoff to prevent entry into waterways or drains
Personal Precautions: Evacuate area, ventilate, eliminate all ignition sources, use non-sparking tools, avoid breathing vapors
Protective Equipment: Gloves resistant to chemicals, eye protection, antistatic shoes, suitable respiratory protection in case of significant vapor release
Environmental Precautions: Prevent further leakage or spillage if safe to do so, keep out of waterways, sewers, and drains
Clean-up Methods: Absorb with inert material (sand, earth, vermiculite), collect in suitable closed containers for disposal, ensure proper labeling
Handling: Handle in well-ventilated area, keep containers tightly closed, use explosion-proof equipment, ground and bond containers during transfers, avoid inhalation of vapor or skin contact, wash thoroughly after handling
Storage Conditions: Store in cool, dry, well-ventilated area away from sources of ignition, heat, oxidizers, acids, and direct sunlight
Storage Packaging: Use approved containers, keep away from incompatible products, contain inhibitor to prevent polymerization
Incompatibilities: Strong acids, bases, oxidizers, reducing agents, peroxides
Occupational Exposure Limits: No established OSHA PEL or ACGIH TLV for this product; use local guidelines where available
