4. First Aid Measures

Inhalation: Move individual to fresh air. Seek medical attention if symptoms persist. Respiratory irritation can develop from dust or fumes.
Skin Contact: Wash skin thoroughly with soap and water. Remove contaminated clothing and launder before reuse. Affected skin may show mild redness or irritation.
Eye Contact: Rinse eyes cautiously with water for several minutes. Remove contact lenses if easy to do. Continue rinsing. Medical attention improves outcomes if irritation continues.
Ingestion: Rinse mouth with water. Do not induce vomiting. Seek medical help if feeling unwell.
Most Important Symptoms: Redness, itching, and discomfort for eyes and skin; possible sore throat, coughing, or headache after inhalation.
Advice for Medical Personnel: Symptomatic treatment and supportive care. No specific antidote.

5. Fire-Fighting Measures

Flammable Properties: Not easily ignited but combustible at high temperatures. Decomposition releases corrosive and toxic gases.
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Media: High-pressure water can spread molten material
Hazards During Fire: Hydrogen chloride, phosgene, carbon monoxide and dioxide may be generated
Firefighting Instructions: Wear self-contained breathing apparatus and protective suit. Approach fire from upwind direction. Avoid inhaling combustion products.
Explosion Risk: Dust clouds may explode in confined spaces if ignited.

6. Accidental Release Measures

Personal Protection: Prevent contact with skin, eyes, and inhalation of dust. Wear gloves, goggles, and respiratory protection.
Methods for Cleanup: Collect material using non-sparking tools. Sweep up and place in compatible containers for disposal. Avoid creating dust.
Environmental Precautions: Prevent entry into drains, waterways, or soil. Use barriers to stop further movement.
Waste Disposal: Dispose of in accordance with local, regional, and national regulations. Label all waste for content and hazards.
Decontamination: Wet small amounts with water to minimize airborne dust, clean area with industrial detergents.

7. Handling and Storage

Handling Precautions: Ground all equipment to dissipate static electricity. Use only in well-ventilated areas. Avoid breathing dust and contact with skin or eyes.
Hygiene: Wash hands before breaks and after work. No eating, drinking, or smoking in handling area.
Storage Requirements: Store away from incompatible materials like strong oxidizers, acids, and alkalis. Keep in a dry, cool, well-ventilated place away from heat sources.
Storage Temperature: Recommended 5–35°C (41–95°F). Avoid freezing or prolonged exposure to heat.
Packaging: Use sealed, labeled containers made of material resistant to chlorine compounds.

8. Exposure Controls / Personal Protection

Exposure Limits: No specific occupational exposure limits for CPO, but consider limits for nuisance particulates (OSHA PEL: 15 mg/m³ total, 5 mg/m³ respirable fraction)
Engineering Controls: Local exhaust ventilation or general mechanical ventilation in areas with dust formation.
Personal Protection: Respiratory protection if dust may be inhaled (e.g., NIOSH-approved dust mask). Chemical-resistant gloves (nitrile, neoprene). Safety glasses or full-face shields. Protective work clothing.
Other Measures: Eyewash stations and safety showers in work areas. Remove contaminated clothing promptly.

12. Ecological Information

Ecotoxicity: Low toxicity observed for aquatic organisms. Fish LC50 (96 hr): > 100 mg/L
Bioaccumulation: Potential for low accumulation. High molecular weight polymers tend not to bioaccumulate significantly.

Mobility in Soil: Practically immobile due to polymer structure
Other Effects: Avoid uncontrolled release to natural water bodies. Long-term effects from microplastics not fully characterized

13. Disposal Considerations

Disposal Methods: Dispose of as non-hazardous industrial waste if uncontaminated; otherwise follow hazardous waste rules. Preferred route is incineration in approved facilities.
