First Aid Measures

Inhalation: Move affected person to fresh air, monitor for irritation, seek medical attention if symptoms persist
Skin Contact: Wash exposed skin with soap and water, remove contaminated clothing, seek medical attention for persistent irritation
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, obtain medical attention if discomfort continues
Ingestion: Do not induce vomiting, rinse mouth, never give anything by mouth to an unconscious person, consult physician if large amounts are ingested
Most Important Symptoms/Effects: Mechanical irritation to eyes, skin, and respiratory tract

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide
Unsuitable Extinguishing Media: Avoid direct water stream on burning resin to prevent scattering
Specific Hazards: Decomposition products include hydrogen chloride gas, carbon monoxide, carbon dioxide
Protective Equipment for Firefighters: Wear self-contained breathing apparatus (SCBA), full protective clothing
Special Procedures: Cool exposed containers with water spray, ventilate area, avoid inhalation of fumes
Flammability: Combustible dust hazard may occur during handling of powder
Autoignition Temperature: > 400°C
Explosion Data: Dust may form explosive mixtures in air under certain conditions

Accidental Release Measures

Personal Precautions: Wear appropriate PPE including dust mask, goggles, and gloves, keep unprotected personnel away
Environmental Precautions: Prevent entry into waterways, sewers, or soil, sweep up spilled powder and avoid generating dust
Cleanup Methods: Use non-sparking tools, collect mechanically, place in suitable containers for disposal, ventilate area well
Emergency Procedures: Evacuate area for large spills, avoid breathing dust

Handling and Storage

Handling: Avoid creating dust, ensure adequate ventilation, ground equipment to prevent static discharge, do not handle near open flame or hot surfaces
Storage: Store in tightly closed containers in a cool, dry, well-ventilated area away from incompatible materials (acids, oxidizers), keep out of direct sunlight
Incompatibilities: Strong acids, alkalies, oxidizers
Special Requirements: Use explosion-proof electrical equipment in areas where dust formation is likely, label containers clearly, keep containers upright

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific limits established for powder; ACGIH TLV for nuisance particulates: 10 mg/m3 total dust, 3 mg/m3 respirable fraction
Engineering Controls: Use local exhaust ventilation to control dust at point of generation, maintain negative pressure in handling areas
Personal Protection Equipment: Safety goggles or face shield, NIOSH-approved dust mask or respirator for airborne powder, impervious gloves
Hygiene Measures: Wash hands before breaks and at end of work, avoid contact with skin and eyes, do not eat, drink or smoke in handling areas
Environmental Controls: Implement spill prevention and containment measures near drains, utilize HEPA-filtered vacuum systems rather than dry sweeping

Toxicological Information

Acute Toxicity: Inhalation of dust may cause mild irritation to respiratory tract; oral toxicity is low due to poor absorption
Skin Irritation: Prolonged or repeated contact may cause mild irritation due to mechanical abrasion
Eye Effects: Dust may produce mild, temporary irritation
Chronic Effects: Long-term exposure to excessive dust levels can contribute to chronic respiratory issues
Carcinogenicity: Product as supplied is not classified as carcinogenic; trace monomeric vinyl chloride (CAS 75-01-4) present below established thresholds (<0.1%), which is not expected to present significant risk under normal use
Mutagenicity: Not expected in polymer form according to data available
Reproductive Toxicity: None reported
Sensitization: No evidence of sensitization in animal studies or workplace use

Ecological Information

Ecotoxicity: No acute toxicity to aquatic or terrestrial organisms anticipated due to solid, insoluble nature; large material spills may pose physical hazards to aquatic life (entanglement, ingestion)

Disposal Considerations

Waste Disposal: Avoid disposing into drains or natural waterways, collect and send to licensed landfill or incineration facility if allowed
Recycling: Clean scrap material may be recycled, subject to local industrial recycling programs
Special Precautions: Minimize generation of dust during disposal, comply with federal, state and local environmental regulations, do not incinerate in open containers
