Common Name: Furfuralcohol, also widely called furfuryl alcohol.
Chemical Formula: C5H6O2
CAS Number: 98-00-0
Physical State: Usually appears as a colorless to pale yellow liquid, though it darkens when exposed to air.
Odor: Has a strong, unpleasant, sometimes almond-like smell that makes it easy to identify by scent during spills or leaks.
Health Hazards: Exposure can irritate the eyes, skin, and respiratory tract. Inhaling high concentrations sometimes causes headaches, dizziness, weakness, and nausea. Repeated contact raises chances of dermatitis, and eye exposure brings pain or burns. Ingestion triggers gastric upset, vomiting, and more serious symptoms with larger amounts.
Fire Hazards: Furfuralcohol’s vapors catch fire easily. Containers can explode if heated by a fire, releasing toxic fumes that endanger those nearby. Even small amounts spilled in confined spaces quickly reach flammable concentrations.
Environmental Risks: Toxic to aquatic life in concentrated form, sometimes spreading damage beyond immediate spill sites.
GHS Classification: Labels warn about toxicity, skin and eye irritation, acute toxicity through skin and inhalation, and environmental threats.
Main ingredient: Furfuryl alcohol, rarely containing impurities.
Purity: High purity levels, usually exceeding 98%; by-products include trace furfural and water.
Inhalation: Move the person to fresh air. If breathing is difficult, seek urgent medical evaluation because symptoms progress quickly with concentrated exposure.
Skin Contact: Remove contaminated clothing, rinse affected skin with copious water and mild soap. Prolonged washing cuts the risk of delayed blistering or burns. Medical attention is necessary for persistent irritation.
Eye Contact: Flush eyes under running water for at least 15 minutes. Remove contact lenses early in the process to improve results. Pain, redness, or lasting discomfort require a prompt medical check.
Ingestion: Rinse mouth with water, avoid inducing vomiting, and consult a medical provider as furfuryl alcohol causes stomach upset or more serious effects even in small amounts.
Suitable Extinguishers: Carbon dioxide, dry chemical powder, or alcohol-resistant foam deal best with small and medium fires.
Hazardous Combustion Products: Burning produces carbon monoxide, carbon dioxide, and toxic aldehydes.
Advice for Firefighters: Wear self-contained breathing apparatus and protective clothing. Keep run-off from entering drains, as the spread of hot, contaminated water adds further health and fire risks. Cooling of exposed, closed containers helps prevent sudden explosions.
Explosion Risk: Vapors form explosive mixtures with air in poorly ventilated spaces or confined areas.
Personal Protection: Use non-sparking tools along with gloves, goggles, and chemical-resistant boots. Respiratory protection is crucial indoors or if vapor concentrations rise.
Spill Response: Contain leaks with suitable barriers, soak up spills with non-combustible absorbents such as sand or earth, never with sawdust or other organic materials that react with Furfuralcohol. Gather residues into a sealed, labeled container for disposal.
Ventilation: Maximize airflow to disperse vapors. If a major spill occurs inside, evacuation sometimes becomes necessary.
Handling: Prevent contact with skin and eyes, avoid splashing, and keep containers tightly closed during transfers. Only trained users should handle open containers, taking care to prevent vapor buildup. Proper grounding and bonding of containers cut static discharge risk.
Storage: Store in a tightly sealed original container, placed in a cool, dry, well-ventilated location away from heat, open flames, or direct sunlight. Metal containers corrode faster in humid conditions, so routine checks matter. Segregate from oxidizing agents, acids, and strong bases to prevent violent reactions.
Special Notes: Self-polymerization sometimes occurs if stored improperly or for extended periods, causing pressure build-up.
Occupational Limits: Some jurisdictions set permissible exposure limits, typically around 5 ppm for an eight-hour shift, though these limits might differ by country.
Engineering Controls: Local exhaust ventilation greatly reduces inhalation risks. Closed systems and splash guards help keep volatilized amounts away from workspaces.
Personal Protection: Chemical-resistant gloves, face shields, and full goggles defend against splashes. Long-sleeved chemical aprons or coveralls protect body and limbs during transfers or cleanup. Respiratory masks rated for organic vapors are essential in poorly ventilated or high-exposure tasks.
Appearance: Clear liquid turning yellow to brown over time with air exposure.
Boiling Point: Around 170–172°C.
Melting Point: About -20°C.
Flash Point: Close to 67°C (closed cup).
Vapor Pressure: Low at room temperature, but increases in heat.
Solubility: Miscible with water, alcohols, and most organic solvents.
Density: Near 1.13 g/cm3.
Chemical Stability: Normally stable under recommended storage and use conditions, but undergoes slow polymerization in the presence of air or bright light, especially if acids are present.
Incompatible Materials: Strong acids, bases, oxidizing agents, and some metals such as aluminum or zinc. These accelerate decomposition or violent chemical reactions.
Hazardous Reactions: Exothermic polymerization remains a real threat in sealed containers left in hot places. Mixing with oxidizers sometimes causes fires or explosions.
Acute Toxicity: Inhalation, ingestion, or skin contact causes irritation and burning at relatively low doses. Occasional headaches, nausea, and central nervous system symptoms arise, especially in poorly ventilated workplaces.
Chronic Effects: Prolonged or repeated exposure causes defatting of skin, persistent irritation, and allergic reactions in sensitive individuals. Some workers report transient blurred vision or respiratory discomfort, raising questions about long-term exposure.
Carcinogenicity: No firm proof links furfuryl alcohol to human cancer, but animal studies suggest a cautious approach.
Routes of Exposure: Mainly inhalation and skin contact; less commonly ingestion.
Aquatic Toxicity: Even small amounts wipe out freshwater organisms, disrupts food chains, and leaves traces in sediments for long periods if clean-up fails to address run-off.
Persistence: Biodegrades in soil and water over time, but breakdown rates fall sharply in oxygen-poor environments.
Bioaccumulation: Does not significantly persist in living organisms, yet recurring spills cause chronic low-level harm in sensitive marshes or rivers.
Safe Disposal: Send contaminated residues and cleanup materials to approved hazardous waste facilities. Pouring it down drains or into open land causes wider contamination of water sources and soil.
Incineration: Professional incinerators effectively destroy furfuryl alcohol, but only with complete controls to capture and treat toxic fumes.
Legal Compliance: Follow local and international waste regulations strictly—hazardous waste transport demands thorough labeling and containment to prevent accidental releases during transit.
UN Number: Classified as a flammable liquid under hazardous goods rules.
Packing Group: Assignment varies by region and packaging method. Containers require secure closure, tough enough for rough handling.
Labeling: Marked with prominent hazards including flammability, toxicity, and environmental risk pictograms.
Special Conditions: Keep away from heat and corrosion, transport only when containers are leak-proof and correctly labeled.
Workplace Standards: Major regulatory agencies classify furfuryl alcohol as hazardous, with rules for reporting and cleanup of spills above given quantities.
Labeling Requirements: Bottles, drums, and shipping cartons require hazard statements, health warnings, and response instructions on all sides.
Community Right-to-Know: Certain jurisdictions put it on chemical disclosure lists, making public reporting of storage locations and volumes mandatory.
Environmental Protection: Strict limits govern emissions to air and water during manufacturing or disposal.
Import/Export: Cross-border movement faces inspection and legal oversight due to recognized toxicity and potential misuse.
