Skin Contact: Wash area gently with soap and water, get medical advice if redness or irritation occurs
Ingestion: Rinse mouth, do not induce vomiting, seek medical attention if adverse symptoms appear
General Advice: For persistent symptoms, consult a healthcare professional

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide, or water spray
Unsuitable Extinguishing Media: Direct stream of water can cause spattering of molten product
Hazards: Combustion may produce irritating smoke, carbon monoxide, and carbon dioxide
Protective Equipment: Firefighters should wear standard protective equipment including self-contained breathing apparatus
Special Procedures: Cool containers exposed to fire with water spray to prevent bursting, ensure safe evacuation in case of major fire

Accidental Release Measures

Personal Precautions: Avoid inhaling dust or fumes, avoid skin and eye contact, use personal protective gear
Environmental Precautions: Prevent large spills from entering drains, watercourses, or soil
Methods for Cleaning Up: For solid product, sweep up and place in suitable container; for molten product, allow to cool and harden before handling
Disposal: Follow disposal guidelines described in disposal section, avoid creating dust

Handling and Storage

Handling Recommendations: Minimize dust generation, keep material away from heat and open flame, avoid eating or drinking during handling
Personal Hygiene: Wash hands and face after handling
Storage Conditions: Store in cool, dry, well-ventilated area away from direct sunlight and strong oxidizers
Incompatible Materials: Avoid storing near acids, strong oxidizers, or sources of ignition
Storage Containers: Use containers constructed of compatible materials such as polyethylene, stainless steel, or coated steel

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific limits established; minimize exposure to dust
Engineering Controls: Provide local exhaust ventilation at points of dust or vapor generation
Respiratory Protection: Use suitable dust masks or respirators if handling powder or dust
Eye Protection: Wear safety goggles or glasses to resist splashes

Ecological Information

Ecotoxicity: Data shows low toxicity for aquatic and terrestrial organisms, minimize bulk releases
Persistence and Degradability: Hydrogenated rosin degrades slowly in the environment; not readily biodegradable
Bioaccumulation: Moderately possible due to hydrophobic nature of product

Other Harmful Effects: High concentrations may create physical barriers for aquatic organisms; usually not an issue except in accidental releases
Regulatory Status: Not labeled as environmentally hazardous under most regulations

Disposal Considerations

Disposal Methods: Dispose of in accordance with local, regional, national, and international regulations; preferred method is landfill disposal for solid, non-hazardous waste
Special Precautions: Avoid release into waterways or drains, never burn in open or uncontrolled conditions
Contaminated Packaging: Clean packaging thoroughly before recycling or disposal. If not reusable, treat containers as solid waste
