GHS Classification: Skin Sensitization Category 1, Eye Irritant Category 2, Acute Toxicity (Inhalation, Dust) Category 4
Hazard Statements: May cause allergic skin reaction, may cause respiratory irritation, possible eye irritation
Pictograms: Exclamation mark
Signal Word: Warning
Precautionary Statements: Avoid breathing dust, wear protective gloves and clothing, wash hands thoroughly after handling
Substance: Rosin
Chemical Identity: Resin acids and rosin acids, abietic-type, compounds with formaldehyde
Concentration: 100%
Impurities: Trace amounts of other organic acids
Inhalation: Remove to fresh air, seek medical attention if symptoms develop or persist
Skin Contact: Wash with soap and water, remove contaminated clothing, seek medical care if irritation or rash occurs
Eye Contact: Rinse immediately with water for several minutes, remove contact lenses if present, seek medical attention if irritation persists
Ingestion: Rinse mouth, do not induce vomiting, seek medical care if you feel unwell
Suitable Extinguishing Media: Use foam, dry chemical, or carbon dioxide for small fires, water spray for larger fires
Special Hazards: Fumes can evolve toxic gases such as carbon monoxide, carbon dioxide, and acrolein
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes
Additional Advice: Move containers away from fire if safe, cool tanks with water spray, prevent fire-extinguishing runoff from entering drains or watercourses
Personal Precautions: Avoid breathing dust, ensure adequate ventilation, avoid contact with skin and eyes
Protective Equipment: Wear gloves, safety glasses, dust mask or respirator
Environmental Precautions: Prevent material from entering drains, sewers, watercourses, or soil
Cleanup Methods: Sweep up and place in appropriate containers for disposal, wash spill site after material pick-up is complete
Safe Handling: Avoid creating dust, handle in well-ventilated areas, use local exhaust if needed
Personal Hygiene: Wash hands and exposed skin thoroughly after handling
Storage Conditions: Store in a cool, dry, well-ventilated area away from direct sunlight and incompatible materials such as strong oxidizers
Packaging Materials: Store in tightly sealed containers made of compatible materials to reduce risk of moisture ingress or degradation
Engineering Controls: Provide local exhaust ventilation where dust is generated, use closed handling systems if possible
Eye Protection: Safety glasses or goggles
Hand Protection: Chemical-resistant gloves such as nitrile, neoprene, or PVC
Skin and Body Protection: Long sleeves, closed footwear
Respiratory Protection: Dust mask or respirator approved for particulates where airborne concentrations exceed limits
Workplace Exposure Limits: Occupational exposure limit (OEL) varies, consult local regulations for specific values; ACGIH TLV for rosin core solder pyrolysis products: 0.1 mg/m3 as formaldehyde

Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, acrolein, other aldehydes at elevated temperatures
Possibility of Hazardous Reactions: May react with strong oxidizers violently
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Inhalation of dust or fume may cause respiratory distress or coughing
Skin Corrosion/Irritation: May cause irritation or allergic skin reaction (contact dermatitis reported in sensitive individuals)
Serious Eye Damage/Irritation: Dust may irritate eyes
Respiratory Sensitization: Sensitization possible—prolonged or repeated exposure to soldering fumes may trigger asthma
Carcinogenicity: Not classified as a carcinogen by OSHA, IARC, or NTP
Other Information: Chronic exposure can cause asthma-like symptoms, particularly among workers soldering with rosin-based fluxes; no significant oral toxicity reported under typical use conditions
Ecotoxicity: Low acute toxicity to fish and aquatic invertebrates; not expected to bioaccumulate
Persistence and Degradability: Slowly biodegradable, persistent in the environment if released in large quantities
Mobility in Soil: Low mobility due to low water solubility
Other Adverse Effects: No known significant effects or hazards, but avoid uncontrolled release to prevent accumulation
Disposal Methods: Dispose of waste in accordance with local, state, and national legislation
Container Disposal: Empty containers should be cleaned and recycled where possible, or disposed of as waste
Environmental Cautions: Avoid disposal in sewage systems or watercourses; do not incinerate sealed containers
