Inhalation: Move to fresh air. Dust exposure can cause cough and discomfort. Seek medical help if symptoms persist.
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, lifting eyelids occasionally. Remove contact lenses if present. See a healthcare provider if redness or pain continues.
Ingestion: Rinse mouth with water. Give water to drink. Do not induce vomiting. If large quantities are swallowed or discomfort develops, get medical aid.
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide
Unsuitable Extinguishing Media: High pressure water jet may spread burning resin dust
Specific Hazards: Resin dust mixed with air can ignite and explode. Decomposition generates hydrochloric acid, carbon monoxide, carbon dioxide, acetic acid, and traces of vinyl chloride.
Firefighting Advice: Use self-contained breathing apparatus and chemical protective clothing to avoid exposure to vapors and decomposition gases. Cool fire-exposed containers with water spray.
Combustion Products: Hydrochloric acid, acetic acid, carbon oxides, traces of vinyl chloride
Personal Precautions: Avoid breathing dust. Wear protective clothing, goggles, gloves, and particle mask.
Environmental Precautions: Keep away from drains, soil, surface water. Sweep up and prevent entry into sewers.
Spill Cleanup Methods: Collect spillage by vacuum or wet sweeping to reduce dust formation. Place in suitable containers for disposal. Ventilate area.
Handling: Use in well-ventilated area. Employ measures to control dust at source. Ground equipment to prevent static discharge. Avoid open flames or sparks near dust.
Storage: Keep away from heat, sparks, open flames, direct sunlight. Store in tightly sealed containers in a cool, dry, ventilated area.
Special Notes: Resins can build static electricity. Use appropriate grounding and bonding.
Occupational Exposure Limits: Vinyl chloride (OSHA PEL: 1 ppm TWA; ACGIH TLV: 1 ppm TWA), Vinyl acetate (OSHA PEL: 10 ppm TWA)
Engineering Controls: Local exhaust ventilation to control dust. Process enclosure.
Respiratory Protection: Dust mask or NIOSH-approved respirator for particle exposure
Eye Protection: Chemical safety goggles or face shield
Skin Protection: Gloves, long-sleeved protective clothing
Other Protection: Wash hands before eating, smoking, or using restrooms.
Appearance: White to off-white powder or granular resin
Odor: Faint; vinegar-like on heating
Odor Threshold: Not established
pH: Not applicable
Melting Point: Softening range 60–100°C, dependent on grade
Boiling Point: Not applicable (polymeric solid)
Flash Point: Product can form dust clouds that are combustible above 400°C
Flammability: Resin dust may combust in air
Auto-Ignition Temperature: Above 400°C
Vapor Pressure: Negligible at room temperature
Solubility: Insoluble in water; soluble in some organic solvents
Density: 1.2–1.4 g/cm³
Chemical Stability: Stable in sealed containers under ordinary conditions
Conditions to Avoid: Excessive heat, open flame, sparks, static discharge, strong oxidizing agents
Incompatible Materials: Strong acids, strong bases, oxidizers
Hazardous Decomposition: Hydrogen chloride, acetic acid, carbon oxides, trace vinyl chloride
Polymerization: Polymer is stable, hazardous polymerization will not occur during recommended handling
Acute Toxicity: Resin dust can irritate eyes, skin, respiratory tract. Major toxic effects unlikely under normal handling.
Chronic Effects: Prolonged exposure to dust may cause respiratory symptoms. Vinyl chloride monomer, present only as a trace impurity, is a known human carcinogen.
Routes of Exposure: Inhalation, skin, eye, ingestion (uncommon)
Symptoms: Irritation, cough, redness, dryness
Sensitization: Not expected
Mutagenicity, Carcinogenicity, Reproductive Toxicity: Resin polymer is not classified; trace vinyl chloride monomer has IARC Group 1 classification (carcinogenic to humans) but levels typically far below hazardous concentration
Ecotoxicity: Resin is not readily biodegradable; expected to have low toxic impact on aquatic life but may persist as microplastics
Persistence and Degradability: Not rapidly biodegradable; persistent in soil and water
Bioaccumulation: Potential for bioaccumulation not significant for polymers
Mobility in Soil: Low, due to solid, insoluble form
Other Adverse Effects: Releases of dust or particles can contribute to solid pollution in waterways; maintain good industrial practices to limit emissions
Waste Treatment Methods: Dispose of material in accordance with local, state, and federal regulations for polymer waste
Recycling: Recycling as industrial scrap possible in some facilities
Unused Material: Incinerate with proper air pollution controls or landfill where permitted
Packaging: Rinse empty containers if required before recycling or disposal. Do not reuse empty drums for food or drink.
UN Number: Not regulated for transport as hazardous material
Proper Shipping Name: Not a restricted article under international transport regulations
Transport Hazard Class: Not classified
Packing Group: Not assigned
Marine Pollutant: No
Special Precautions: Protect from moisture, ignition sources, and physical damage during transport; avoid release of dust
OSHA Status: Not hazardous as a polymer bulk material. Trace monomer subject to OSHA regulations.
TSCA (Toxic Substances Control Act): Listed
SARA Title III (Sections 311/312): Not regulated for bulk resin; trace monomer may be subject to reporting
