Hazard Identification

Classification: Combustible dust, Skin irritant, Suspected carcinogen (due to vinyl chloride trace residuals)
GHS Label Elements: Warning, exclamation mark symbol
Hazard Statements: Causes skin irritation, may form explosive dust-air mixtures, suspect carcinogen
Precautionary Statements: Prevent dust accumulation; use in well-ventilated areas; avoid skin contact

Composition / Information on Ingredients

Substance: Vinyl Chloride-Vinyl Acetate Copolymer
Chemical Makeup: Vinyl chloride (typically >80%), vinyl acetate (<20%)
Impurities: Unreacted vinyl chloride monomer (trace), residual additives, stabilizers
Other Identifiers: Molecular Weight Range: 50,000–100,000 g/mol

First Aid Measures

Inhalation: Move person to fresh air, support breathing, seek medical attention for respiratory symptoms
Skin Contact: Wash with soap and water, remove contaminated clothing, get medical advice if irritation develops
Eye Contact: Rinse with plenty of water for several minutes, remove contact lenses if present, continue rinsing, obtain medical help
Ingestion: Rinse mouth, drink water to dilute, do not induce vomiting, contact poison control or physician

Fire-Fighting Measures

Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Hazards Arising: Combustion may release hydrogen chloride, carbon monoxide, carbon dioxide, phosgene in severe cases
Advice for Firefighters: Use self-contained breathing apparatus, full protective gear, cool containers exposed to flames, avoid inhaling gases
Special Information: Polymer dust can form combustible mixtures with air, avoid dust clouds

Accidental Release Measures

Personal Precautions: Wear protective equipment, remove ignition sources, ventilate area
Environmental Precautions: Prevent polymer from entering drains, watercourses, or soil
Containment and Cleanup: Use non-sparking tools, collect spilled material for disposal, vacuum dust with explosion-proof equipment, avoid dry sweeping

Handling and Storage

Safe Handling: Minimize dust generation, avoid skin and eye contact, use local exhaust ventilation
Storage Conditions: Store in a cool, dry place, keep containers tightly closed, avoid heat and sunlight, store away from strong acids, bases, oxidizers
Other Recommendations: Keep product away from food and animal feed, check containers for damage before storage

Exposure Controls and Personal Protection

Exposure Limits: Vinyl chloride TLV: 1 ppm (OSHA), vinyl acetate ACGIH TLV: 10 ppm
Engineering Controls: Local exhaust ventilation, process enclosure, explosion-proof equipment
Personal Protective Equipment: Safety glasses with side shields, dust respirator (NIOSH approved), chemical-resistant gloves, work clothing covering skin surfaces
Hygiene Measures: Wash thoroughly after handling, do not eat, drink, or smoke in work area

Physical and Chemical Properties

Appearance: White powder or granular solid
Odor: Faint plastic odor, odorless in most cases
pH: Not applicable (insoluble polymer)
Melting Point: >120°C
Boiling Point: Not applicable (decomposes before boiling)
Density: 1.15–1.40 g/cm³
Solubility: Insoluble in water; soluble in organic solvents (acetone, cyclohexanone, toluene)
Flash Point: Not determined for solid form
Vapor Pressure: Negligible at room temperature
Auto-Ignition Temperature: Above 400°C
Explosive Limits: Dust may form explosive mixtures within air (exact range not specified)

Stability and Reactivity

Chemical Stability: Stable under normal handling conditions
Conditions to Avoid: Heat, flames, sparks, strong sunlight, incompatible chemicals
Incompatible Materials: Strong oxidizing agents, strong acids, strong bases
Hazardous Decomposition: Thermal decomposition may produce hydrogen chloride, carbon monoxide, phosgene
Polymerization: Will not undergo hazardous polymerization in storage

Toxicological Information

Acute Effects: Dust inhalation may irritate respiratory tract; skin and eye contact may cause mild irritation
Chronic Effects: Repeated or prolonged inhalation of dust could affect respiratory health; potential carcinogenicity linked to residual vinyl chloride
Carcinogenicity: Vinyl chloride classified as IARC Group 1 carcinogen; resin itself shows low carcinogenic risk unless contaminated with unreacted monomer
LD50 (oral, rat): >5,000 mg/kg (estimated, low toxicity)
Sensitization: Not reported in studies for this copolymer form

Ecological Information

Environmental Fate: Non-biodegradable synthetic polymer, persists in the environment
Aquatic Toxicity: Not acutely toxic to fish or aquatic life, but physical effects possible due to accumulation
Soil Mobility: Not mobile; insoluble and settles rapidly from water
Bioaccumulation: Not expected to bioaccumulate due to macromolecular size
Other Information: Debris and microplastics can contribute to long-term pollution in aquatic systems

Disposal Considerations

Waste Treatment Methods: Dispose of in compliance with local, regional, and national regulations as nonhazardous polymeric waste
Recommended Disposal: Landfill or controlled incineration; burning may produce toxic gases, so incinerators require proper scrubbing systems
Recycling: Polymer recycling possible in facilities equipped for similar plastics, though mechanical destruction usually preferred

Transport Information

UN Number: Not classified as dangerous for transport under most global regulations
Transport Hazards: Not a regulated hazardous material unless fine powder transported in bulk (combustible dust risk)
Packing Group: Not assigned
Special Precautions: Avoid transporting near heat or ignition sources, protect from moisture and physical damage, label containers clearly

Regulatory Information

Inventory Listings: Polymer registered under major chemical inventories (TSCA, EINECS/ELINCS, ENCS, AICS)
Carcinogen Status: Vinyl chloride monomer subject to strict controls (OSHA, IARC, NTP); finished resin (with residuals below legal limits) typically exempt
Hazard Communication: Compliant with GHS/OSHA standards for industrial chemicals
Other Regulations: Ensure workplace exposure limits for vinyl chloride and acetate observed; comply with city, state, and national laws for chemical storage and handling
