Flammability: Combustible dust in air, not classified as highly flammable solid
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide
Hazards During Fire: Decomposes to release hydrogen chloride, carbon monoxide, small amounts of phosgene or acetic acid in confined fires
Special Protective Equipment: Full protective suit, respirator for toxic fumes, self-contained breathing apparatus
Special Procedures: Remove containers from area if safe, prevent runoff, ventilate closed spaces
Explosion Risks: Avoid high dust concentrations; dust clouds can be ignited by static or sparks
Byproducts: Dense smoke, HCl gas, CO, possible low-level organics during smoldering
Personal Precautions: Wear dust mask, goggles, gloves, reduce dust spread, use non-sparking tools
Environmental Precautions: Prevent entry to drains, sewers, or waterways, sweep up without generating dust, cover spillage
Methods for Cleanup: Sweep or vacuum (explosion proof), avoid dry brushing, use water mist for dust control
Notification: Report significant releases to local authorities based on jurisdictional rules
Waste Disposal: Gather residue in labeled, sealable containers for proper disposal as solid chemical waste
Precautions for Handling: Use local ventilation to manage dust, earth containers to discharge static, minimize personal exposure
Safe Storage Conditions: Store in dry, cool, ventilated area, away from direct sunlight and heat
Incompatible Materials: Strong acids, alkalis, oxidizing agents, avoid organic solvents not recommended by supplier
Storage Containers: Keep sealed in original packaging or compatible bins
Hygiene Practices: Wash hands before meals or after handling, avoid eating or drinking in process areas
Special Measures: Minimize piling or stirring to reduce dust clouds, store away from open flames or high energy sources
Exposure Limits: None established for this polymer, observe nuisance dust limits (e.g., OSHA PEL: 15 mg/m³ total dust)
Engineering Controls: Local exhaust at points of dust generation, closed transfer systems
Protective Equipment: Dust mask or respirator rated for particulates, gloves made of nitrile or PVC, chemical safety goggles
Skin Protection: Long sleeve clothing, impervious gloves for handling bulk product

Vapor Pressure: Negligible at room temperature
Partition Coefficient: Not measured, expected inert
Explosive Properties: Dust hazard exists if concentrations in air reach explosive range
Chemical Stability: Stable under normal ambient and recommended storage conditions
Reactivity: Not reactive with most materials, will react with strong acids or alkalis
Hazardous Reactions: Strong oxidizers or excessive heat may trigger breakdown
Conditions to Avoid: Open flames, sparks, static electricity, high temperatures
Incompatible Materials: Amine hardeners, concentrated acids or strong oxidizers accelerate decomposition
Hazardous Decomposition Products: HCl gas, CO, CO₂, acetic acid, vinyl chloride traces under fire or extreme heat

Sensitization: No evidence of skin sensitization
Chronic Toxicity: None observed in chronic occupational exposure studies
Carcinogenicity: Product does not contain free vinyl chloride or other known carcinogens above legal limits
Mutagenicity: Not expected to be genotoxic due to high molecular weight, no evidence found in polymer studies
Reproductive Toxicity: No critical data indicating risk at expected exposure levels
Aquatic Toxicity: Practically insoluble, minimal acute toxicity to fish or daphnia by weight
Bioaccumulation: Polymer particles do not accumulate in aquatic organisms; low bioaccumulation risk
