First Aid Measures

Inhalation: Move to fresh air if irritation occurs, seek medical attention if symptoms persist
Skin Contact: Wash with soap and water, remove contaminated clothing, consult physician if irritation develops
Eye Contact: Rinse eyes with plenty of water, continue for several minutes, seek medical attention if irritation continues
Ingestion: Rinse mouth and drink water, do not induce vomiting unless instructed by medical personnel, seek medical attention
Notes for Physicians: Treat symptomatically, no specific antidote recommended

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Media: Direct water jet may spread molten product
Specific Hazards: Decomposes to emit irritating or toxic fumes including carbon monoxide and carbon dioxide, dust may pose explosion risk if suspended in air
Protective Equipment: Use self-contained breathing apparatus and protective clothing for large fires
Firefighting Advice: Cool containers exposed to fire, evacuate area, prevent water runoff from contaminating waterways

Accidental Release Measures

Personal Precautions: Wear dust mask, goggles, gloves, avoid breathing dust, ventilate area
Environmental Precautions: Avoid discharge into the environment, contain spillage to prevent entry into drains, waterways, or soil
Cleanup Methods: Carefully collect spilled resin, use vacuum with high efficiency particulate filter or wet methods to minimize dust, place in appropriate container for disposal
Notification: Inform authorities if release leads to environmental impact, especially in case of large spills

Handling and Storage

Handling: Minimize dust generation, avoid sources of ignition, wear suitable personal protective equipment such as gloves and masks, wash hands after use, do not eat or drink near material
Storage: Store in a cool, dry, well-ventilated area away from compatible substances like strong oxidizers, keep container tightly closed to protect from moisture and contamination, use containers compatible with hydrocarbon resins, label containers appropriately
Incompatibilities: Avoid contact with strong acids, bases, oxidizers, reduce risk of static discharge by grounding equipment
Special Precautions: Use only in areas with adequate ventilation, monitor for dust accumulation

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific limits established for coumarone resin, control dust below nuisance particulate levels (typically 10 mg/m³ for total dust)
Engineering Controls: Use local exhaust ventilation, process enclosure, and dust collection systems to control airborne levels
Respiratory Protection: Wear approved particulate respirator when dust levels approach permissible exposure levels or during cleaning operations
Eye Protection: Use safety glasses or goggles
Skin Protection: Wear chemically resistant gloves, long-sleeved clothing to minimize direct skin contact
Hygiene Measures: Wash hands before eating, smoking, or using washrooms, remove contaminated clothing and wash before reuse

Physical and Chemical Properties

Appearance: Hard, brittle, yellow to dark brown solid or flakes
Odor: Faint aromatic
pH: Not applicable
Melting Point/Softening Point: Typically ranges from 60°C to 150°C depending on grade
Boiling Point: Decomposes before boiling
Flash Point: Above 200°C (closed cup, varies by grade)
Flammability: Combustible if heated above melting point
Vapor Pressure: Negligible at ambient temperatures
Water Solubility: Insoluble

Stability and Reactivity

Chemical Stability: Stable under normal handling and storage conditions
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, various hydrocarbons if burned
Conditions to Avoid: Extreme heat, open flames, strong oxidizing agents
Incompatible Materials: Strong acids, bases, and oxidizers
Polymerization: Not known to occur under normal conditions

Toxicological Information

Likely Routes of Exposure: Inhalation of dust, skin and eye contact
Acute Toxicity: Low; dust may cause local irritation, very low toxicity if swallowed
Skin Irritation: Prolonged or repeated contact can dry skin, may cause mild redness or irritation
Eye Irritation: Dust can cause mechanical irritation
Inhalation Effects: Dust may trigger coughing, throat and respiratory tract irritation
Ingestion Effects: Unlikely to be toxic in small quantities, large amounts may cause gastrointestinal discomfort
Sensitization: No evidence of skin or respiratory sensitization identified
Carcinogenicity: Not listed as a carcinogen by IARC, NTP, or OSHA
Chronic Effects: Repeated exposure to dust may aggravate existing respiratory conditions

Ecological Information

Aquatic Toxicity: Expected to have low toxicity to aquatic life, insoluble in water
Persistence and Degradability: Not rapidly biodegradable, will persist in environment as a solid
Bioaccumulative Potential: Not expected due to high molecular weight and low solubility
Mobility in Soil: Low; resin particles may settle in soil, unlikely to leach to groundwater
Other Adverse Effects: Spilled resin can create slipping hazard for animals or people, physical impact rather than chemical toxicity is primary risk in environment

Disposal Considerations

Disposal Methods: Dispose in accordance with local, regional, and national regulations; send to permitted waste disposal facility
Contaminated Packaging: Clean containers can be recycled or disposed of as non-hazardous waste; any residue should be managed as industrial waste
Special Precautions: Avoid landfill disposal if feasible, do not allow to enter surface waters
