Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, remove contact lenses if present and easy to do, seek medical attention if irritation persists
Ingestion: Rinse mouth, do not induce vomiting, seek medical advice in case of discomfort
Most Important Symptoms: Mechanical irritation may occur with exposure to dust; redness or dryness in eyes and skin
Advice for Medical Providers: Treat symptomatically

Fire-Fighting Measures

Flammability: Solid resin may burn
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Extinguishing Media: Strong water jet can spread burning material
Special Hazards: Thermal decomposition may produce carbon monoxide, carbon dioxide, hydrocarbons
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Specific Firefighting Methods: Move undamaged containers from fire area if safe to do so, cool containers with water
Explosion Risk: Fine dust­–air mixtures can pose explosion risks

Accidental Release Measures

Personal Precautions: Do not breathe dust, provide adequate ventilation, use personal protective equipment
Environmental Precautions: Do not allow material to enter drains or watercourses
Cleaning Methods: Sweep up or vacuum material without generating dust, collect and dispose in suitable containers
Disposal: Follow regulations on disposal to minimize dust and protect environment
Emergency Procedures: Stop the source of spill if safe, contain material to prevent release into environment

Handling and Storage

Handling: Avoid dust generation, use proper exhaust ventilation, keep away from open flames or ignition sources
Storage: Store in a cool, dry, and well‑ventilated area away from heat, sparks, and sunlight
Keep Container Closed: Seal tightly when not in use
Handling Precautions: Wash thoroughly after handling; do not eat, drink, or smoke while handling
Incompatible Materials: Strong oxidizing agents, acids

Exposure Controls and Personal Protection

Engineering Controls: Provide local exhaust at dust‑generating points
Exposure Limits: No specific ACGIH or OSHA exposure limits for terpene resins
Respiratory Protection: Use NIOSH‑approved dust mask if handling generates dust
Eye Protection: Safety glasses with side shields
Skin Protection: Wear chemical resistant gloves, long sleeves to avoid skin contact

Toxicological Information

Acute Toxicity: Available data shows very low toxicity
Skin Contact: May cause mild irritation, particularly with repeated exposure
Eye Contact: Dust may cause redness or irritation
Inhalation: Excessive exposure to dust can irritate respiratory tract
Ingestion: Considered low toxicity; not intended for ingestion
Chronic Effects: Not classified as carcinogen, mutagen, or reproductive toxin by OSHA, IARC, NTP, or EU
Sensitization: Not expected to cause allergy but avoid direct prolonged contact
Medical Conditions Aggravated: Persons with respiratory diseases may experience aggravation from dust exposure

Ecological Information

Aquatic Toxicity: Expected to have low mobility and bioaccumulation potential in aquatic environments
Persistence and Degradability: Material is slowly biodegradable; not readily soluble in water
Bioaccumulative Potential: Low due to large molecular size
Other Adverse Effects: No known significant effects, but avoid uncontrolled release into environment
Soil Mobility: Inert solid; unlikely to migrate through soil

Disposal Considerations

Product Disposal: Dispose in accordance with local, regional, and national regulations; landfilling or incineration permitted where authorized
