First Aid Measures
Inhalation: Remove exposed person to fresh air. Get medical attention for any respiratory discomfort or if symptoms persist.
Skin Contact: Wash affected area with soap and water. Remove and wash contaminated clothing. For persistent skin irritation, seek medical advice.
Eye Contact: Flush eyes gently with plenty of water for at least 15 minutes, lifting eyelids. Seek medical attention if irritation develops.
Ingestion: Rinse mouth thoroughly. Drink water if person is conscious. Do not induce vomiting unless directed by a medical professional. Seek medical help for any discomfort.
Most Important Symptoms: Eye and respiratory irritation; coughing, sneezing, redness.
Notes for Physician: Treat symptomatically. No specific antidote known.
Fire-Fighting Measures
Suitable Extinguishing Media: Use dry chemical, foam, water spray, or carbon dioxide for surrounding fire. Water spray may help to cool unopened containers.
Unsuitable Extinguishing Media: Avoid use of high-pressure water streams that may spread dust.
Specific Hazards: Can release hydrogen chloride, carbon monoxide, and carbon dioxide on decomposition.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Special Procedures: Cool closed containers exposed to fire with water. Evacuate area and fight fire from a safe distance.
Combustion Products: Hydrogen chloride, phosgene, and oxides of carbon.
Accidental Release Measures
Personal Precautions: Wear approved dust mask, goggles, and gloves. Remove all sources of ignition. Ventilate area to prevent dust accumulation.
Spill Cleanup Methods: Pick up spill with a vacuum equipped with HEPA filter or sweep up gently to minimize dust. Use dust suppressant if appropriate.
Environmental Precautions: Prevent entry into sewers, waterways and soil. Inform local authorities if significant quantities enter the environment.
Disposal: Collect waste in labelled containers for proper disposal as required by local regulations.
Handling and Storage
Handling: Minimize dust generation and accumulation. Ensure adequate ventilation during processing. Use tools and equipment that do not generate sparks.
Storage: Store in original, tightly sealed containers in a cool, dry, well-ventilated place away from direct sunlight, heat, and ignition sources.
Incompatible Materials: Avoid storing with strong oxidizers, acids, and alkalis.
Other Recommendations: Ground all equipment to prevent static discharge. Keep away from food, drink, and animal feeding areas.
Exposure Controls and Personal Protection
Occupational Exposure Limits: OSHA PEL for nuisance dust: 15 mg/m³ (total dust); 5 mg/m³ (respirable). ACGIH TLV: 10 mg/m³ (inhalable).
Engineering Controls: Ensure mechanical ventilation or local exhaust, especially in confined spaces. Use explosion-proof equipment where needed.
Personal Protective Equipment:
- Respiratory Protection: Use NIOSH-approved dust respirators if exposure limits are exceeded.
- Eye Protection: Wear safety goggles or face shield to protect from dust.
- Skin Protection: Wear gloves and long sleeves to prevent irritation.

Toxicological Information
Likely Routes of Exposure: Inhalation, skin, eyes
Acute Toxicity: Not acutely toxic. LD50 (oral, rat) > 5,000 mg/kg
Chronic Toxicity: Long-term exposure to high dust concentrations may affect lungs. No evidence of carcinogenicity for the resin. Residual monomer (vinyl chloride) is carcinogenic, but present at trace levels.
Respiratory Effects: Irritation of respiratory mucous membranes, possible aggravation of asthma.
Eye Effects: May cause mechanical irritation, redness, tearing.
Skin Effects: Prolonged or repeated contact may cause slight irritation.
Mutagenicity / Carcinogenicity: No significant data for finished resin. Monomeric vinyl chloride is carcinogenic (IARC Group 1) at high chronic exposure.
Other Effects: No sensitization or reproductive toxicity anticipated at occupational exposure limits.
Ecological Information
Aquatic Toxicity: Low water solubility limits acute and chronic effects on aquatic life.
Persistence and Degradability: Persistent in environment; very slow degradation under ambient conditions.
Bioaccumulative Potential: Not expected to bioaccumulate due to large molecular size and insolubility.
Soil Mobility: Low; tends to settle and remain in sediments.
Additional Information: Avoid release to environment; large spills may physically cover soil or aquatic surfaces, possibly impacting organisms by smothering.
Disposal Considerations
Waste Disposal Methods: Follow local, regional, and national regulations for disposal of resin waste. Landfill or incinerate at an approved facility. Avoid uncontrolled releases or burning.
Contaminated Packaging: Clean thoroughly before recycling or dispose of in accordance with legal requirements.
Precautions: Do not flush material into drains or sewers. Prevent dispersion into air during waste handling.
