Hazard Identification

Classification: Not classified as hazardous under GHS; avoid inhalation of dust or particles
Most important hazards: Dust may irritate respiratory passages and eyes. Heated material may release hydrogen chloride or acetic acid vapors.
Label elements: None required for dust-free solid. For powders, use standard dust hazard pictogram.
Potential health effects: Shortness of breath, coughing, eye irritation on direct contact.
Undesirable fire behavior: Emits toxic vapors under fire, including HCl and acetic acid.

Composition / Information on Ingredients

Main Ingredients: Vinyl Chloride (as incorporated in polymer), Vinyl Acetate, Carboxyl Modifiers
Chemical nature: Carboxyl-functionalized copolymer resin
Chemical formula: Proprietary copolymer structure
Impurities contributing to hazard: Residual monomers below threshold limits
CAS Numbers: Vinyl Chloride: 75-01-4 (polymerized form), Vinyl Acetate: 108-05-4 (polymerized form)
Typical content: Vinyl Chloride 60–90%, Vinyl Acetate 10–40%, Carboxyl Modifier <5%

First Aid Measures

Inhalation: Move affected person to fresh air. Seek medical attention if symptoms persist.
Skin contact: Wash with soap and water. Remove contaminated clothing.
Eye contact: Flush thoroughly with cool water for 15 minutes. Remove contact lenses.
Ingestion: Rinse mouth. Do not induce vomiting unless directed by medical personnel.
Most important symptoms: Itching, redness, coughing, sneezing, eye discomfort
Advice to physician: Treat symptomatically, monitor for irritation or allergic reaction.

Fire-Fighting Measures

Suitable extinguishing media: Foam, water spray, dry chemical, CO₂
Unsuitable agents: Direct water stream may spread burning resin
Specific hazards: Heated resin emits hydrogen chloride, acetic acid; dense black smoke may reduce visibility
Protective equipment for firefighters: Self-contained breathing apparatus, full protective gear.
Explosion risk: Dust in high concentrations may create combustion risk.
Advice for firefighters: Evacuate nonessential personnel. Cool fire-exposed containers.

Accidental Release Measures

Personal precautions: Wear dust mask, safety goggles, gloves; avoid raising dust
Environmental precautions: Prevent discharge into sewers or waterways
Methods for containment: Collect in suitable containers for disposal. Sweep up spills to reduce slipping hazard.
Methods for cleaning up: Wet sweeping or HEPA vacuuming recommended to minimize airborne dust
Decontamination procedures: Wash area with ample water after spill clean-up.

Handling and Storage

Precautions for safe handling: Minimize dust generation, use with local exhaust, avoid skin and eye contact
Advice on general occupational hygiene: Prohibit eating, drinking, smoking in handling area; wash hands before meals
Storage conditions: Store in cool, dry, ventilated area, away from heat or ignition sources
Container requirements: Keep containers tightly closed when not being used; use approved packaging materials
Incompatibilities: Strong oxidizers, acids, and alkalis
Storage temperature: Store below 40°C, away from sunlight

Exposure Controls and Personal Protection

Occupational exposure limits: No established limits for finished copolymer; refer to local regulations for nuisance dust
Engineering controls: Use local exhaust, ventilation, process enclosures
Personal protective equipment: Dust mask or respirator (for powders), safety glasses or goggles, chemical-resistant gloves, protective clothing
Environmental controls: Prevent material from entering drains or the environment
Hygiene measures: Shower after handling; wash contaminated clothing before reuse

Physical and Chemical Properties

Form: Solid resin, available as powder or pellets
Color: White to off-white
