Ingestion: Rinse mouth thoroughly, call poison control or physician, do not induce vomiting
Notes to Physicians: Treat symptomatically; provide supportive care and consider potential dust inhalation injuries
Fire-Fighting Measures
Suitable Extinguishing Media: Dry chemical, foam, CO2, water spray; avoid high-pressure water streams
Hazardous Combustion Products: Hydrogen chloride, phosgene, carbon monoxide, carbon dioxide, organic acids
Special Protective Equipment: Full-face self-contained breathing apparatus, fire-resistant clothing
Advice for Firefighters: Control run-off to prevent environmental contamination, cool exposed containers, stand upwind from fire
Accidental Release Measures
Personal Precautions: Wear dust masks, chemical-resistant gloves, eye protection; ensure proper ventilation
Environmental Precautions: Prevent material from entering drains or waterways, collect spillage for proper disposal
Methods for Cleanup: Sweep or vacuum up without generating dust, use explosion-proof equipment, store collected material in sealed containers
Handling and Storage
Safe Handling: Use local exhaust ventilation, avoid dust creation, ground equipment to dissipate static electricity, handle with protective gear
Storage Conditions: Store in dry, cool, well-ventilated areas, keep containers tightly closed, segregate from strong oxidizers, acids, or alkalis
Incompatible Materials: Strong acids, alkalis, oxidizing agents can react with resin, avoid mixing with incompatible materials
Special Precautions: Avoid contact with open flames or high temperatures, control sources of ignition in storage and handling areas
Exposure Controls and Personal Protection
Exposure Limits: NIOSH TWA for particulates not otherwise regulated (PNOR): 10 mg/m3 (total dust), 5 mg/m3 (respirable fraction)
Engineering Controls: Local exhaust, general ventilation for dust-prone areas, explosion-proof electrical equipment
Personal Protective Equipment: Safety glasses, dust mask or respirator (NIOSH-approved), gloves resistant to chemicals, standard work clothing
Hygiene Measures: Wash hands and exposed skin before breaks and after handling, remove contaminated clothing after exposure
Physical and Chemical Properties
Appearance: White to off-white powder or resin granules
Odor: Faint vinyl or acetic acid odor
Odor Threshold: Not established

Stability and Reactivity
Chemical Stability: Stable under normal conditions, degrades under prolonged heat or UV
Conditions to Avoid: High temperatures, sparks, flames, exposure to direct sunlight
Incompatible Materials: Strong acids, strong oxidizers, or alkalis, excessive heat
Hazardous Decomposition Products: Hydrogen chloride, phosgene, acetic acid, carbon monoxide, carbon dioxide
Polymerization: Product is stable; hazardous polymerization will not occur under normal use
Toxicological Information
Acute Toxicity: Low toxicity expected from ingestion, inhalation, or skin contact with bulk resin
Skin Corrosion/Irritation: Mild irritation with repeated or prolonged exposure, possible dermatitis
Serious Eye Damage/Irritation: May cause mechanical irritation to the eyes by dust
Respiratory Sensitization: Dust may aggravate existing respiratory conditions, especially asthma
Carcinogenicity: Vinyl chloride monomer classified as carcinogenic, finished resin contains negligible monomer; exposure risk mainly in processing stages
Reproductive Toxicity: No data suggesting terpolymer causes reproductive harm
Long-term Effects: Long or repeated exposure to dust may cause respiratory irritation
Medical Conditions Aggravated by Exposure: Pre-existing respiratory or skin disorders
Ecological Information
Aquatic Toxicity: Large spills may cause physical stress to aquatic systems, product does not dissolve or degrade easily
Mobility in Soil: Expected to be immobile, heavier than water, settles in sediment
Persistence and Degradability: Resin resists natural degradation processes, persistent in environment
Bioaccumulation: Not known to biomagnify, no significant data on bioconcentration
Other Adverse Effects: Can physically smother aquatic plants and animals if discharged in large quantities
Disposal Considerations
Waste Treatment Methods: Dispose as industrial waste according to local, state, federal, or national requirements
Special Precautions: Do not burn in open air; avoid generating dust during disposal; consider recycling if feasible
