4. First Aid Measures

Eye Contact: Rinse cautiously with water for several minutes; seek medical attention if irritation persists
Skin Contact: Wash exposed skin with soap and water; for molten resin, do not remove solidified product—seek immediate medical help
Inhalation: Remove individual to fresh air; consult physician if breathing problems develop
Ingestion: Rinse mouth, drink water to dilute, do not induce vomiting, seek medical advice
Most Important Symptoms: Mild irritation, possible redness or discomfort
Indication of Immediate Medical Attention: Chemical burns from molten product or signs of respiratory distress

5. Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray
Specific Hazards: Can generate smoke, carbon monoxide, carbon dioxide, and other hydrocarbons during combustion
Protective Equipment for Firefighters: Full protective suit and self-contained breathing apparatus
Firefighting Procedures: Cool exposed containers with water spray; prevent runoff into drains
Explosion Data: Dust clouds may present explosion risk if dispersed in air under specific conditions
Unusual Fire Hazards: Heated product releases fumes; pools of molten resin can re-ignite after initial extinguishing

6. Accidental Release Measures

Personal Precautions: Wear gloves, long sleeves, and eye protection; avoid creating dust clouds
Environmental Precautions: Prevent entry into sewers, drains, or natural waterways
Cleanup Methods: Sweep or shovel spilled material into containers for disposal; ventilate area to avoid accumulation of fumes or dust
Disposal: Collect residue and dispose of as non-hazardous industrial waste unless mixed with other hazardous substances

7. Handling and Storage

Precautions for Safe Handling: Avoid dust generation, use local exhaust if necessary, wash hands after handling
Safe Storage Conditions: Keep in tightly closed containers, store in cool, dry, well-ventilated location away from heat and ignition sources
Incompatible Materials: Strong oxidizing agents, acids
Other Handling Considerations: Use caution when transferring hot or molten resin to prevent burns; check bulk containers for signs of leaks

8. Exposure Controls and Personal Protection

Engineering Controls: Good general ventilation required; local exhaust recommended for dust or heated resin
Occupational Exposure Limits: No established TLV for this resin, but minimize exposure to nuisance dust (OSHA PEL for particulates: 15 mg/m3 total)
Eye Protection: Safety goggles if handling dust or molten resin
Skin Protection: Chemical-resistant gloves, long-sleeve clothing, thermal protection when handling hot material
Respiratory Protection: NIOSH-approved mask if dust levels exceed exposure limits
Other Protective Equipment: Emergency eye wash and safety shower available in work area

9. Physical and Chemical Properties

Appearance: Light yellow to amber pellets, flakes, or pastilles
Odor: Faint hydrocarbon odor
Melting Point/Range: 80–140°C (varies by grade)
Boiling Point: Not applicable (polymeric solid, decomposes before boiling)

Flash Point: Typically >230°C (COC method)
Vapor Pressure: Negligible at ambient temperature
Auto-Ignition Temperature: Above 350°C
pH: Not applicable
Percent Volatile: Negligible

10. Stability and Reactivity

Chemical Stability: Stable under recommended handling and storage conditions
Thermal Decomposition: Breaks down at high temperatures, can release irritant fumes
Hazardous Reactions: Strong oxidizers may react violently
Conditions to Avoid: Excessive heat, sparks, open flames
Incompatible Materials: Oxidizing agents, acids, halogens
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, hydrocarbon fumes, possible traces of aldehydes

11. Toxicological Information

Acute Toxicity: Oral and dermal toxicity low based on resin structure; no significant hazard from expected exposure routes
Skin Corrosion/Irritation: Generally non-irritant, molten resin causes burns
Serious Eye Damage/Irritation: Solid resin may cause mild transient irritation
Respiratory Sensitization: Prolonged exposure to dust could irritate lungs, but not a sensitizer
Carcinogenicity: Not considered carcinogenic by OSHA, ACGIH, NTP, or IARC
Other Possible Effects: No evidence of reproductive or developmental toxicity
Chronic Effects: Prolonged skin contact might dry or crack skin

12. Ecological Information

Ecotoxicity: Practically non-toxic to aquatic organisms at normal concentrations
Persistence and Degradability: Slowly biodegradable; persists in soil or sediment
Bioaccumulation Potential: Limited based on high molecular weight and chemical stability
Mobility in Soil: Low, tends to remain in solid form
Other Environmental Hazards: Bulk or pellet material can cause physical obstruction to wildlife if discharged in large amounts

13. Disposal Considerations

Waste Disposal: Dispose of as general industrial waste; landfill or incineration according to local regulations
Container Handling: Clean and reuse or recycle containers if possible
Sewage Disposal: Do not allow resin or slurries to enter waterways or drains
Special Precautions: Approved waste handler should manage large volumes or contaminated material
