Hazard Identification

Classification: Flammable liquid, irritant
GHS Label Elements: Flame, exclamation mark
Hazard Statements: Highly flammable liquid and vapor, may cause eye and skin irritation, harmful if inhaled or swallowed
Precautionary Statements: Keep away from heat and ignition sources, wear proper protective equipment, use in well-ventilated areas
Other Hazards: Vapors may form explosive mixtures with air, prolonged or repeated exposure can dry skin

Composition / Information on Ingredients

Chemical Identity: Solketal
CAS Number: 100-79-8
Concentration: ≥99% (typical in commercial products)
Impurities and Stabilizing Additives: Low-level trace impurities may vary by supplier, not typically significant at laboratory grade

First Aid Measures

Inhalation: Remove person to fresh air, keep comfortable, seek medical attention if symptoms persist or worsen
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, seek medical attention for irritation
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present and easy to do, continue rinsing, get medical help
Ingestion: Rinse mouth, do not induce vomiting unless instructed by medical personnel, seek immediate medical attention
Notes for Doctors: Treat symptomatically, no known antidote, monitor for respiratory or cardiovascular complications

Fire-Fighting Measures

Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide, water spray can be used for small fires
Hazards During Fire: Vapors may travel and ignite; combustion forms hazardous gases such as CO, CO₂
Special Protective Equipment for Firefighters: Use self-contained breathing apparatus, full protective gear
Firefighting Procedures: Remove containers from fire if safe, use water spray to cool surfaces, avoid runoff entering drains

Accidental Release Measures

Personal Precautions: Evacuate area, ensure adequate ventilation, eliminate ignition sources, avoid breathing vapors
Protective Equipment: Wear gloves, goggles, chemical-resistant clothing
Cleanup Method: Contain spillage, absorb with inert material (sand, vermiculite), collect and transfer to waste containers, prevent entry into sewers or watercourses
Environmental Precautions: Notify authorities if product enters sewage or aquatic environments, avoid dispersal in soil or water system

Handling and Storage

Precautions for Safe Handling: Use in spark-free areas with local exhaust ventilation, avoid inhaling vapor or direct contact, keep away from open flame
Storage Conditions: Store in tightly closed container in a cool, well-ventilated place away from heat or ignition sources
Incompatible Materials: Strong acids, bases, oxidizing agents
Specific Requirements: Regularly inspect containers for buildup of pressure, clear labeling, proper secondary containment practices can prevent accidental leaks and spills

Exposure Controls and Personal Protection

Engineering Controls: Use chemical fume hood, local exhaust ventilation, explosion-proof electrical equipment
Personal Protective Equipment: Gloves (nitrile or similar material), eye protection (safety goggles), lab coat, closed shoes
Respiratory Protection: Suitable respirator if ventilation is poor
Hygiene Measures: Wash hands after handling, remove contaminated clothing, avoid eating, drinking or smoking in work areas
Exposure Limits: No established occupational exposure limits, handle as a potential irritant

Decomposition Products: Carbon monoxide, carbon dioxide, other toxic fumes may form during fire or thermal decomposition

Toxicological Information

Acute Toxicity: Low acute toxicity, but ingestion, inhalation, or direct contact may cause moderate irritation
Skin Corrosion/Irritation: Can irritate skin after prolonged or repeated exposure
Serious Eye Damage/Irritation: Moderate eye irritant
Respiratory Sensitization: Vapor inhalation may lead to irritation
Long-term Exposure Effects: No sufficient evidence from animal or epidemiological studies of long-term harm
Carcinogenicity, Mutagenicity, Reproductive Toxicity: Not classified as such by major regulatory agencies
Medical Considerations: Persons with pre-existing skin, respiratory, or allergic conditions may be more sensitive

Ecological Information

Ecotoxicity: Not classified as dangerous for aquatic life, but large volumes may be harmful
Persistence/Degradability: Readily biodegradable in the environment
Bioaccumulative Potential: Not expected to bioaccumulate significantly
Mobility in Soil: Soluble in water, may move through soil and potentially reach groundwater
Other Adverse Effects: No evidence for ozone depletion potential, but responsible disposal and spill prevention reduce ecosystem impacts

Disposal Considerations

Disposal Methods: Send to licensed chemical disposal facility, observe local, national, and international regulations
Contaminated Packaging: Rinse containers thoroughly before recycling or disposal, handle as chemical waste
Special Precautions: Do not allow product to reach sewage, surface, or ground water, avoid incineration without pollution controls
