First Aid Measures

Inhalation: Move to fresh air, seek medical attention if respiratory irritation persists
Eye Contact: Rinse eyes for several minutes with lukewarm water, ensure no particles remain in the eye
Skin Contact: Wash exposed skin with soap and water; for contact with molten resin, cool affected area immediately under running water, do not remove adhered product, seek medical attention for burns
Ingestion: Rinse mouth; do not induce vomiting, seek medical attention if discomfort occurs
Notes to Physician: No specific antidote; treat symptoms as required

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, carbon dioxide, water spray, foam
Unsuitable Extinguishing Media: Strong water jet may spread burning molten resin
Special Hazards: Burning resin emits thick smoke and potentially hazardous decomposition gases such as carbon monoxide and carbon dioxide
Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Firefighting Procedures: Cool fire-exposed containers with water spray; prevent runoff from contaminating storm sewers or waterways

Accidental Release Measures

Personal Precautions: Avoid inhalation of dust and contact with molten material; wear protective equipment
Environmental Precautions: Prevent material from reaching sewers, waterways, or soil
Methods for Cleanup: Sweep or shovel solid material into suitable labeled containers for reclamation or disposal; for molten resin, allow to cool and solidify before removal; ventilate enclosed spaces before re-entry
Recovery: Collect uncontaminated spill for recycling or disposal

Handling and Storage

Handling: Avoid breathing dust or fumes; prevent contact with eyes and skin, particularly at elevated temperatures; implement local exhaust ventilation in work areas with high dust or fume concentration
Storage Conditions: Store in a cool, dry, well-ventilated area, away from direct sunlight, heat sources, and incompatible chemicals such as strong oxidizers
Packaging Materials: Use polyethylene-lined bags or moisture-resistant containers
Hygiene Practices: Wash hands after handling resin and before eating or drinking
Risk Mitigation: Process at the lowest feasible temperature to minimize fumes

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific regulatory exposure limits established
Respiratory Protection: Use a NIOSH-approved respirator if airborne dust or fume concentrations exceed comfort levels; ensure local exhaust ventilation during hot processing
Eye Protection: Wear safety glasses or chemical goggles for dust or molten resin
Skin Protection: Use impervious gloves for melted material; long-sleeved clothing recommended
Engineering Controls: Enclose processes, provide local exhaust, monitor airborne dust with routine air quality checks

Conditions to Avoid: Excessive heat, open flames, and sunlight; mechanical impact
Hazardous Polymerization: Does not occur under standard industrial conditions
Hazardous Decomposition Products: Oxides of carbon, low molecular weight hydrocarbons, soot if poorly combusted

Toxicological Information

Routes of Exposure: Inhalation (dust or fumes), skin and eye contact, ingestion
Acute Toxicity: Low toxicity; dust or fumes can cause mild irritation
Chronic Toxicity: Prolonged or repeated skin contact may cause dryness or irritation
Sensitization: No evidence of skin or respiratory sensitization
Carcinogenicity: Not listed as a carcinogen by OSHA, IARC, NTP or ACGIH
Mutagenicity and Reproductive Toxicity: No data suggesting mutagenic or reproductive risks
Symptoms of Overexposure: Mild respiratory discomfort, skin and eye irritation possible during extended exposure to dust, fumes or molten product

Ecological Information

Ecotoxicity: Low environmental toxicity; solid resin is not readily bioavailable
Persistence and Degradability: Product persists in the environment, slowly degraded by sunlight and physical weathering
Bioaccumulative Potential: Not expected to bioaccumulate due to low water solubility and high molecular weight
Mobility: Product tends to remain in soil or sediments rather than leaching into water
Aquatic Toxicity: Not anticipated to cause harm to aquatic life under normal handling and accidental releases
Other Harmful Effects: No reports of adverse ecological effects in the published literature

Disposal Considerations

Waste Treatment Methods: Dispose of resin in accordance with local, regional, and national regulations
Unused Product: Reuse where possible, or send to permitted landfill or incineration facilities
Contaminated Packaging: Empty packaging thoroughly before recycling or disposal; follow governmental directives
Incineration: Suitable for incineration under controlled conditions; avoid uncontrolled burning
Precautions: Do not discharge resin waste to surface water or sewage systems
