Inhalation: Move to fresh air. Seek medical attention if breathing feels difficult or coughing continues.
Skin Contact: Wash area thoroughly with soap and water. Remove contaminated clothing.
Eye Contact: Rinse eyes with low-pressure water for at least 15 minutes. Remove contact lenses.
Ingestion: Rinse mouth, drink water if conscious, never give anything by mouth to an unconscious person. Seek doctor if significant quantities swallowed.
Note to Physician: Treat symptomatically; provide supportive care.
Flammability: Dust might catch fire in air, bulk resin resists ignition
Suitable Extinguishing Media: Dry chemical powder, foam, CO2, water spray for cooling
Unsuitable Media: Direct water jets may scatter burning dust
Special Hazards: Toxic hydrogen chloride, phosgene and vinyl chloride fumes released in combustion
Protective Equipment: Self-contained breathing apparatus, full turnout gear for firefighters
Explosion Hazard: High dust concentrations in air risk dust explosions
Advice for Firefighters: Cool containers, keep upwind, do not allow run-off into drains
Personal Precautions: Remove sources of ignition, avoid inhalation of dust
Protective Equipment: Dust mask or respirator, gloves, protective clothing, goggles
Environmental Precautions: Prevent entry into drains, watercourses
Methods for Cleanup: Sweep up with anti-static equipment, avoid generating dust, collect for disposal in labelled containers
Reference to Other Sections: See exposure controls and disposal guidance
Handling: Use with adequate ventilation, minimize dust creation, handle away from heat, sparks, open flames
Technical Measures: Use grounding and bonding for containers, tools, to avoid static discharge
Storage Conditions: Store in cool, dry, well-ventilated area, in tightly closed containers
Incompatible Materials: Strong oxidizers, acids
Storage Class: General chemical storage
Special Rules: Keep away from ignition sources and moisture, segregate from foodstuffs
Exposure Limits: OSHA PEL (Vinyl Chloride, monomer): 1 ppm TWA; dust: treat as nuisance dust 10 mg/m³
Engineering Controls: General and local exhaust ventilation
Personal Protection: Dust mask (NIOSH approved), goggles, gloves and protective clothing (cotton/antistatic material recommended)
Hygiene Measures: Wash hands after handling, do not eat/drink in work area, change contaminated clothing
Environmental Exposure Control: Dust filters for exhaust, prevent atmospheric release

Partition Coefficient (n-octanol/water): Not determined
Auto-ignition Temperature: Approx. 450°C
Chemical Stability: Stable in normal conditions, stable to light and air
Reactivity: Strong acids, bases, oxidizers may degrade resin
Conditions to Avoid: High temperature, open flames, electrostatic discharge
Decomposition Products: Releases hydrogen chloride, phosgene, and dioxins under fire/thermal decomposition
Polymerization: Not expected under normal use
Acute Toxicity: Low, may cause mild irritation to eyes, skin, respiratory tract
Specific Effects: Dust exposure may lead to coughing, sneezing, skin dryness with prolonged contact
Chronic Exposure: No specific evidence of harm at common workplace levels, trace monomers of vinyl chloride are carcinogenic, importance of controlling dust and monomer residuals
Sensitization: Not expected
Carcinogenicity: Copolymer itself does not pose cancer risk, but unreacted vinyl chloride monomer regulated due to carcinogenicity
Reproductive Effects: Not established for copolymer, monomer is suspected hazard
Medical Conditions Aggravated: Pre-existing respiratory conditions
Mutagenicity: No relevant data for copolymer
Ecotoxicity: Not expected to be acutely toxic to aquatic life, but polymer particles can disrupt ecological balance if released in quantity
Persistence and Degradability: Not readily biodegradable, persistent in aquatic and soil environments
Bioaccumulative Potential: Not expected to bioaccumulate
Mobility in Soil: Low, tends to settle in sediment
Other Adverse Effects: Physical hazard to wildlife from pellet ingestion
Waste Treatment Methods: Dispose of according to local, state, federal regulations
Disposal of Product: Landfill or controlled incineration; avoid discharge to environment
Disposal of Contaminated Packaging: Treat packaging as contaminated waste, offer to licensed waste disposal service
Recycling: Where possible, send for reprocessing
Additional Information: Do not incinerate in open air; toxic gases may form
