Chemical Name: Vinyl Acetate
Concentration: ≥ 99%, depending on formulation
Impurities: Trace amounts of acetic acid, water, acetaldehyde
Molecular Weight: 86.09 g/mol
Inhalation: Remove to fresh air without delay. Seek medical attention for breathing difficulties or persistent symptoms.
Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Medical attention if irritation persists.
Eye Contact: Rinse eyes thoroughly with water for at least 15 minutes, holding eyelids open. Remove contact lenses if present and easy to do. Get medical attention immediately.
Ingestion: Do not induce vomiting. Rinse mouth with water. Get medical attention.
Symptoms: Coughing, headache, dizziness, eye and skin irritations, respiratory discomfort.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, water spray (do not use water jet directly on the substance).
Unsuitable Media: Direct water jet may disperse and spread fire.
Specific Hazards: Emits flammable vapors heavier than air. Vapors may travel to ignition sources. Decomposition produces carbon monoxide, carbon dioxide, acetic acid.
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective clothing.
Additional Information: Cool fire-exposed containers with water spray. Avoid breathing combustion gases. Evacuate area if necessary.
Personal Precautions: Evacuate unnecessary personnel. Eliminate ignition sources. Ventilate affected area. Wear suitable personal protective equipment including gloves, goggles, and respirators.
Environmental Precautions: Prevent runoff into drains, surface water, or soil. Notify appropriate authorities if large quantities enter the environment.
Containment and Cleanup: Stop leaks if safe to do so. Absorb with inert material such as sand, earth, or vermiculite. Collect in suitable containers for disposal. Wash contaminated area with water after spill pickup.
Handling Precautions: Keep container tightly closed when not in use. Avoid contact with skin, eyes, and clothing. Do not breathe vapor or mist. Use only in well-ventilated places. Ground/bond containers and receiving equipment.
Storage Conditions: Store in cool, dry, well-ventilated areas away from heat, sparks, and open flames. Store away from oxidizing agents, acids, and bases. Keep containers tightly sealed and clearly labeled.
Storage Temperatures: Storage recommended below 30°C (86°F).
Incompatible Materials: Strong oxidizers, acids, alkalis, amines.
Occupational Exposure Limits: OSHA PEL: 10 ppm (35 mg/m³); ACGIH TLV: 10 ppm TWA
Engineering Controls: Use local exhaust ventilation and process enclosure to control exposure.
Personal Protective Equipment (PPE): Respiratory protection such as NIOSH-approved respirators if exposure limit exceeded. Chemical-resistant gloves (e.g., nitrile). Safety goggles or face shield. Protective clothing or apron.
Hygiene Measures: Wash hands before breaks and at the end of work. Separate work clothing from personal clothing.
Appearance: Colorless, volatile liquid
Odor: Sweet, fruity

Vapor Pressure: 108 mmHg at 20°C (68°F)
Vapor Density: 3 (air = 1)
Relative Density: 0.934 (water = 1)
Solubility: Moderately soluble in water (2.5 g/100 mL at 20°C); miscible with organic solvents
Partition Coefficient: log Kow = 0.73
Auto-Ignition Temperature: 402°C (756°F)
Chemical Stability: Stable under recommended storage and handling conditions. Vapors may form explosive mixtures with air.
Reactivity: Avoid contact with oxidizing agents, acids, and bases.
Hazardous Reactions: May polymerize violently with acidic, basic, or oxidative catalysts. Can form peroxides in the presence of air.
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, acetic acid, flammable gases.
Polymerization: Polymerization may occur with heat, light, or contamination.
Acute Toxicity: LD50 oral (rat): 2900 mg/kg; LC50 inhalation (rat): 11.4 mg/L (4 hours)
Skin Corrosion/Irritation: Causes moderate skin irritation.
Serious Eye Damage/Irritation: Causes severe eye irritation.
Respiratory or Skin Sensitization: No reliable evidence of sensitization.
Carcinogenicity: IARC Group 2B (possibly carcinogenic to humans); not listed as a known carcinogen by NTP or OSHA
Reproductive Toxicity: No reliable evidence of reproductive harm in humans from typical exposures.
Other Effects: Headache, drowsiness, nausea, sore throat with high exposure. Central nervous system depression possible with prolonged exposure.
Eco-Toxicity: Moderately toxic to aquatic organisms. LC50 (fish, 96 h): 26–86 mg/L. EC50 (daphnia, 48 h): 52 mg/L. Can cause long-term effects in aquatic systems.
Bioaccumulative Potential: Low to moderate; log Kow suggests low bioaccumulation.
Degradation: Biodegradable in water and soil, but breaks down into acetic acid and other organic compounds.
