Hazardous Components: The copolymer itself not typically hazardous, monomer residue managed under strict exposure limits
Inhalation: Move affected person to fresh air, monitor for breathing difficulties, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash with soap and water, consult a physician for persistent irritation
Eye Contact: Rinse eyes immediately with plenty of water for at least 15 minutes, hold eyelids open, seek medical advice if irritation remains
Ingestion: Rinse mouth with water, do not induce vomiting, obtain medical attention if discomfort develops
Notes to Physician: Symptomatic care; material is inert but may carry contaminants that need consideration
Most Important Symptoms: Mechanical irritation to skin, eyes, and upper airways
Flammability: Finely divided dust can ignite if a suitable ignition source is present
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, foam
Unsuitable Media: Direct water jet on burning dust clouds increases risk of dust explosion
Specific Hazards: Hazardous gases (hydrogen chloride, carbon monoxide, carbon dioxide) can form from incomplete combustion
Protective Equipment: Firefighters wear full protective gear and self-contained breathing apparatus
Special Procedures: Cool exposed containers, avoid stirring dust deposits, control run-off to avoid environmental contamination
Combustion Products: Includes hydrochloric acid gas and traces of acetic acid fumes
Personal Protection: Avoid inhaling dust, use respirators and protective clothing
Spill Clean-up: Collect mechanically, avoid dry sweeping, use approved industrial vacuum if available
Environmental Precautions: Prevent material from entering sewage and waterways
Dealing with Dust: Mist with water to suppress dust (do not use if incompatible with product), ventilate area
Disposal of Spills: Place recovered material in closed, labeled containers for safe disposal
Notification Procedures: Notify safety authorities and follow facility emergency plans for polymer dust incidents
Safe Handling: Use local exhaust ventilation when processing granules or powders, handle as per industrial hygiene standards, ground equipment to prevent static discharge
Precautions: Avoid generating airborne dust, keep away from open flames, sources of ignition, and hot surfaces
Hygiene Recommendations: Wash hands and exposed skin after handling, do not eat or drink nearby
Storage Conditions: Store in cool, dry, well-ventilated place, keep containers tightly closed
Incompatibilities: Strong oxidizers, strong acids, and strong bases
Storage Temperature: Standard ambient conditions unless otherwise specified
Packaging Materials: Keep in original packaging, polyester film bags or drums preferred
Storage Class: Non-dangerous goods; combustible solid precautions apply
Control Parameters: OSHA PEL for vinyl chloride 1 ppm TWA, ACGIH TLV for vinyl acetate 10 ppm TWA, ensure that residual monomer levels in workspace air are monitored
Engineering Controls: Use process enclosures, local exhaust or general room ventilation to control airborne dust
Personal Protection:
Form: White to off-white powder or granular solid
Odor: Slightly sweet or none
pH: Neutral in aqueous suspension
Melting Point: Softening > 120°C (varies with ratio)
Boiling Point: Not applicable (decomposes before boiling)

Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Inert in most environmental scenarios
Conditions to Avoid: Heat, flames, ignition sources, electrostatic discharge, strong oxidizing agents
Hazardous Reactions: Strong acids or oxidizers may cause exothermic reactions and breakdown
Decomposition Products: Hazardous gases released at high temperatures include hydrogen chloride, acetic acid, carbon monoxide
Polymerization Risk: Not expected under normal conditions
Shelf Life: Years if stored away from sunlight and moisture
Acute Toxicity: Material has low toxicity by oral, dermal, and inhalation routes; dust may irritate mucous membranes

Respiratory Effects: Overexposure to dust can result in coughing, shortness of breath
Sensitization: No known skin or respiratory sensitization risk
Carcinogenicity: Based on current formulation, the resin is not classified as a carcinogen; residual vinyl chloride is present in trace levels well below worker exposure limits
Mutagenicity: No data suggesting genetic toxicity for the copolymer
Repeated Exposure: Prolonged inhalation of dust may worsen symptoms in people with asthma or chronic respiratory disease
Ecotoxicity: Polymer is not readily biodegradable, small polymer particles may be harmful to aquatic life by physical interference
Persistence and Degradability: Resistant to biological degradation, breakdown occurs over many years in soil or water
Bioaccumulation: Polymer particles may accumulate in the environment, not bioaccumulative in the food chain
