Synonyms: Acetic acid ethenyl ester
Concentration: 99% or higher
Stabilizers: Hydroquinone or similar inhibitors (typically below 100 ppm)
Inhalation: Move person to fresh air, keep at rest in a position comfortable for breathing, call a physician if symptoms persist or develop
Skin Contact: Remove contaminated clothing, wash area thoroughly with soap and water, seek medical attention for persistent irritation
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, obtain medical advice
Ingestion: Rinse mouth with water, do not induce vomiting, immediately call poison center or a physician
Most Important Symptoms: Respiratory tract irritation, dizziness, headaches, skin or eye redness or swelling
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, water spray for cooling
Unsuitable Media: Direct water stream may spread fire
Specific Hazards: Vapors can form explosive mixtures with air, combustion produces irritating, toxic fumes including acetic acid and carbon monoxide
Protective Equipment for Firefighters: Use self-contained breathing apparatus and full protective gear
Special Procedures: Evacuate area, cool exposed containers with water spray, prevent run-off from entering drains or watercourses
Personal Precautions: Evacuate unnecessary personnel, ventilate area, eliminate ignition sources, wear protective equipment including gloves, goggles, and respirator
Containment Methods: Prevent further leakage or spillage if safe to do so, stop leaks at source
Spill Clean-Up: Absorb with inert material (sand, earth, vermiculite), collect into labeled containers for disposal, use non-sparking tools
Environmental Precautions: Do not let product enter drains, waterways, or soil
Precautions for Safe Handling: Use only with adequate ventilation, avoid breathing vapor, prevent contact with eyes, skin, or clothing, ground and bond containers when transferring, keep away from ignition sources, static discharge precautions required
Conditions for Safe Storage: Store in tightly closed containers in cool, dry, well-ventilated place, segregated from oxidizers and acids, maintain inhibitor levels, check containers regularly for leaks or corrosion, protect from direct sunlight and heat
Incompatibilities: Strong acids, strong bases, oxidizing agents, peroxides
Occupational Exposure Limits: OSHA PEL: 10 ppm (35 mg/m³), ACGIH TLV: 10 ppm TWA, 15 ppm STEL
Engineering Controls: Use explosion-proof ventilation, enclose sources, ensure emergency eyewash and showers are available
Personal Protective Equipment: Chemical-resistant gloves, splash-proof goggles or face shield, flame-resistant clothing, respiratory protection (NIOSH-approved respirator) for high vapor concentrations
Hygiene Measures: Wash hands thoroughly after handling, avoid eating, drinking, or smoking during use, remove contaminated clothing and wash before reuse
