Inhalation: Remove affected person to fresh air, monitor for persistent symptoms, seek medical attention for labored breathing
Skin Contact: Wash affected area thoroughly with soap and water, remove contaminated clothing, apply moisturizer if irritation appears
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if easily possible, seek medical help if irritation lasts
Ingestion: Rinse mouth, do not induce vomiting, give small sips of water, seek medical advice if large amounts are swallowed or symptoms appear
Special Advice for Physicians: Treat symptomatically, provide supportive measures if respiratory, dermal, or ocular irritation persists
5. Fire-Fighting Measures
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, sand, avoid water if possible due to potential resin runoff
Unusual Fire and Explosion Hazards: Dust poses risk of explosion in confined spaces, resin decomposes to irritant or toxic gases when heated
Protective Equipment: Full protective gear and self-contained breathing apparatus for fire-fighters
Fire-Fighting Instructions: Move containers from fire area if not risky, keep cool with gentle water spray, prevent spillage from entering drains
Combustion Products: Possible release of carbon monoxide, carbon dioxide, phenolic fumes, faint formaldehyde under incomplete combustion
6. Accidental Release Measures
Personal Precautions: Evacuate area of spill, ventilate if dust or fume present, wear proper protective equipment including dust mask and impervious gloves
Environmental Precautions: Prevent entry into soil, drains, or waterways, inform authorities if spill causes contamination
Cleanup Methods: Sweep or shovel up solid material with non-sparking tools, place in labeled containers for recycling or disposal, avoid generating dust
Further Precautions: Decontaminate the area with detergent and water, wash tools before reuse
7. Handling and Storage
Handling Practices: Avoid inhaling dust and fumes, use mechanical exhaust where dust generation occurs, prevent skin and eye contact, keep in areas away from heat and open flames, ground all transfer equipment to minimize static discharge
Storage Conditions: Store in cool, dry, well-ventilated place, keep containers tightly sealed, segregate from oxidizers and strong bases, use containers made of compatible material
Incompatible Materials: Strong acids, strong alkalis, oxidizing agents, avoid contact to prevent hazardous reactions, keep away from sources of ignition
8. Exposure Controls and Personal Protection
Occupational Exposure Limits: No established occupational exposure limit for finished resin, observe limits for any included dust or volatile components such as formaldehyde (ACGIH TLV for formaldehyde 0.3 ppm)
Engineering Controls: Use local exhaust ventilation for dust-heavy work, ensure adequate fresh air exchange, handle powders in closed systems if possible
Personal Protective Equipment: Wear nitrile or neoprene gloves, chemical safety goggles, coveralls or protective clothing to minimize skin exposure, NIOSH-approved dust mask or respirator if airborne dust or fumes expected
Hygiene Measures: Wash hands thoroughly after handling, remove and launder contaminated clothing, keep eating areas separate from work area
9. Physical and Chemical Properties
Physical State: Solid, granular, flake, or block
Color: Yellow to deep brown
Odor: Mild, resinous
Boiling Point: Not applicable
Melting Point: Softening point 80–140°C (varies by grade)
Flash Point: Above 225°C
Explosive Limits: Fine dusts may form explosive mixtures in air
Vapor Pressure: Negligible at ambient temperature
Solubility: Insoluble in water, soluble in many organic solvents such as alcohols, ethers
Density: About 1.05–1.20 g/cm³
pH: Not applicable as solid
Viscosity: Not relevant for solid material
10. Stability and Reactivity
Chemical Stability: Stable under normal storage and use conditions
Heat Sensitivity: Avoid prolonged heating above softening temperature to prevent decomposition
Reactivity: Unreactive under standard industrial practices, hazardous reactions unlikely under normal conditions
Incompatible Substances: Strong oxidizers, acids, bases, some solvents, avoid mixing with other chemicals unless compatibility is known
Hazardous Decomposition Products: Heats to decomposition release carbon monoxide, carbon dioxide, phenolic vapors, trace formaldehyde gas
11. Toxicological Information
Acute Toxicity: Low toxicity by inhalation, ingestion, or skin contact for finished resin
Routes of Exposure: Inhalation causes cough, headache, or discomfort in sensitive individuals, skin contact results in dryness, eye contact triggers irritation, ingestion produces upset stomach
Chronic Effects: Extended exposure to dust or fumes increases risk of skin and respiratory sensitivity; persons with prior allergies at higher risk
Carcinogenicity: No classification for resin, minimal risk except for trace formaldehyde or phenolic residuals if present above detection limits
Sensitization: Rare cases of allergic skin or respiratory responses reported among occupational users
12. Ecological Information
Aquatic Toxicity: Very low solubility indicates limited acute aquatic hazard, high concentrations may cause physical fouling
Persistence and Degradability: Resin degrades slowly in environment, sunlight and microbes break down solids over time, not considered readily biodegradable
Bioaccumulation: Unlikely due to molecular structure and physical state
Mobility in Soil: Minimal, resins tend to bind to soil particles and are not readily leached
Other Environmental Impacts: Large spills may cause physical impairment of waterways or block drainage, good practice involves collecting all spilled resin promptly
13. Disposal Considerations
Waste Treatment Methods: Collect solid waste in sealed, labeled containers for professional disposal
Disposal of Product: Send to approved incineration or landfill facility as non-hazardous industrial waste where permitted, follow federal and local regulations
Contaminated Packaging: Clean containers before recycling or dispose under local requirements, do not reuse for food or water
