Component: Vinylene Carbonate
Concentration: > 99%
Molecular Formula: C3H2O3
Molecular Weight: 86.05 g/mol
Impurities: Typically less than 1%; refer to Certificate of Analysis for details.
Decomposition Products: Can yield carbon monoxide, carbon dioxide, and other toxic vapors under fire conditions.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes; seek medical advice as soon as possible.
Skin Contact: Remove contaminated clothing. Wash skin promptly with soap and water. Get medical attention if symptoms develop.
Inhalation: Move person to fresh air. Provide artificial respiration if necessary. Seek medical attention if breathing becomes difficult or symptoms persist.
Ingestion: Rinse mouth thoroughly. Do not induce vomiting unless advised by medical personnel. Seek immediate medical attention.
Most Important Symptoms: Irritation of eyes, skin, respiratory tract; cough, sneezing, headaches, drowsiness in severe exposure.
Suitable Extinguishing Media: Use alcohol-resistant foam, dry chemical, or carbon dioxide. Water spray only for cooling containers; avoid direct water jet.
Specific Hazards: Gives off toxic fumes, including carbon monoxide and carbon dioxide, during combustion. Vapors can create explosive atmosphere.
Protective Equipment: Firefighters should wear full protective clothing and self-contained breathing apparatus.
Advice for Responders: Approach from upwind. Remove containers from fire area if possible. Use water spray to cool surroundings.
Personal Precautions: Evacuate area; provide proper ventilation. Avoid inhalation and contact with skin and eyes. Wear suitable personal protective equipment.
Environmental Precautions: Prevent entry into drains, soil, and natural waterways. Notify environmental authorities if spillage occurs.
Cleanup Methods: Absorb spills with inert material (e.g. vermiculite, sand). Transfer to appropriate waste container for disposal. Clean area thoroughly with water and detergent.
Additional Information: Use spark-proof tools and explosion-proof equipment in cleanup.
Safe Handling: Handle in well-ventilated area. Use spark-resistant tools and non-sparking equipment. Avoid creating aerosols or dust. Do not breathe vapors.
Storage Requirements: Store in cool, tightly closed container, away from sources of ignition and incompatible substances (strong oxidizing agents, acids). Keep in original packaging.
Other Notes: Ground and bond containers to prevent static discharge. Avoid prolonged exposure to air and moisture which could lead to decomposition.
Engineering Controls: Work under chemical fume hood. Install local exhaust ventilation to keep airborne concentration below exposure limits.
Exposure Limits: No established occupational exposure limit for vinylene carbonate. Use general dust/vapor limits as reference.
Respiratory Protection: Wear approved respirator with organic vapor cartridge if ventilation is inadequate.
Eye Protection: Chemical safety goggles or face shield.
Skin Protection: Impermeable gloves (nitrile, neoprene). Wear lab coat or chemical-resistant clothing.
Hygiene Measures: Wash hands and face thoroughly after handling. Remove contaminated clothing before entering eating areas.
