Chemical Name: Toluene
Common Names: Methylbenzene, Phenylmethane
Formula: C7H8
Chemical Family: Aromatic Hydrocarbon
Appearance: Clear, colorless liquid with characteristic sweet and pungent odor
Risk Classification: Flammable liquid, acute toxicity (inhalation, skin), skin and eye irritant, target organ toxicity (nervous system)
Main Risks: Vapor can form explosive mixtures with air. Breathing vapors may cause drowsiness, dizziness, or headaches. Liquid and vapor may irritate eyes, skin, and respiratory tract. Prolonged exposure can affect the central nervous system and may damage liver and kidneys. High levels in confined areas increase the risk of fire or explosion.
Signal Word: Danger
Primary Ingredient: Toluene (CAS: 108-88-3)
Purity: Typically above 99% by manufacturing specifications, impurities kept at trace levels by distillation and QA processes
Minor Impurities: Benzene, xylene, ethylbenzene (usually below regulated thresholds)
Inhalation: Remove from exposure area to fresh air right away. Keep person warm and at rest. Seek medical attention for persistent symptoms such as shortness of breath, headaches, or confusion.
Skin Contact: Remove contaminated clothing and shoes. Wash affected skin with soap and water for at least 15 minutes. Persistent irritation signals need for medical review.
Eye Contact: Rinse cautiously with water for several minutes, lifting eyelids occasionally. Avoid strong streams to prevent splashing. Get prompt medical attention if irritation continues.
Ingestion: Do not induce vomiting. Rinse mouth with water. Seek immediate medical care for any swallowing or aspiration risks.
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide. Water spray useful for cooling exposed containers and reducing vapor but may be less effective for extinguishing.
Hazards from Combustion: Generates toxic fumes of carbon monoxide and carbon dioxide. Vapors can travel significant distances to ignition sources.
Special Protective Equipment: Self-contained breathing apparatus (SCBA) and full protective gear for firefighters. Prevent runoff into drains or water sources due to toxic impact.
Personal Precautions: Evacuate unprotected personnel from area of spill. Use only spark-proof tools and explosion-proof equipment. Wear appropriate protective gear to minimize inhalation and skin contact.
Environmental Precautions: Prevent entry into waterways, sewers, basements, or confined areas. Notify environmental authorities if a significant spill occurs.
Spill Cleanup: Absorb small spills with sand, earth, or non-combustible absorbent material, then transfer to suitable container. Ensure adequate ventilation and remove ignition sources.
Handling: Work in well-ventilated areas or use proper exhaust systems to control vapors. Keep all ignition sources away from storage and handling points. Ground and bond all containers during transfer to avoid static discharge.
Storage: Store in tightly sealed containers in cool, dry, and well-ventilated areas. Drum storage must minimize heat and sun exposure. Avoid contact with oxidizers, acids, and chlorinated compounds.
Engineering Controls: Local exhaust and general ventilation systems reduce airborne concentrations. Continuous leak and vapor detectors inside enclosed spaces or large installations.
Personal Protective Equipment: Chemical splash goggles, nitrile or neoprene gloves, flame-retardant protective clothing, and face shields for splash risk. Use organic vapor respirators for concentrations above exposure limits.
Exposure Limits: TWA 50 ppm (OSHA/ACGIH recommended). Our manufacturing process is designed to minimize airborne exposure and incorporates real-time monitoring.
Physical State: Liquid
Odor Threshold: Detectable at low ppm levels
Boiling Point: 110.6°C
Melting Point: -95°C
Flash Point: 4°C (closed cup)
Vapor Pressure: 28.4 mmHg at 25°C
Density: 0.87 g/cm³ at 20°C
Solubility: Slightly soluble in water; completely miscible with most organic solvents
Chemical Stability: Stable under recommended storage and handling conditions. Sensitive to heat, open flames, and strong oxidizing agents.
Reactivity: Exhibits hazardous reactions with strong acids, chlorinated compounds, or alkali metals. Formation of peroxides possible during prolonged storage.
Hazardous Decomposition Products: Toxic fume generation (CO, CO2) in fires or at high temperature.
Acute Effects: Inhalation causes headaches, dizziness, respiratory irritation. High doses can depress the central nervous system.
Chronic Effects: Long-term exposure may affect liver, kidney, and nervous system function. Not classified as carcinogenic but continuous exposure increases health risks and must be tightly controlled.
Routes of Exposure: Inhalation is primary route in industrial settings. Skin and eye contact pose significant risk during manual handling. Observed health cases underscore the importance of rigorous PPE use in the workplace.
Persistence and Degradability: Toluene degrades relatively quickly by natural processes, but contamination into water or soil disrupts aquatic organisms.
Bioaccumulation: Minimal due to metabolic breakdown, although continuous leaks increase local groundwater and soil burden.
Ecotoxicity: Toxic to fish and other aquatic organisms. In tested spills, small volumes changed oxygen levels and harmed local biota. Environmental spill response on-site always matters, since long-term low-level exposure changes ecosystem dynamics.
Disposal Methods: Incineration at licensed facilities preferred. Drum and container residues classified as hazardous waste.
Precautions: Never discharge to surface water, sewer, or public landfills. Waste haulers must comply with national and regional hazardous regulations. On-site processes recover solvent for reuse where practical, minimizing total discharge volume.
UN Number: 1294
Packaging Group: II (medium hazard)
Hazard Class: 3 (flammable liquid)
Transport Symbols: Flammable Liquid symbol on all containers above lab scale. Personnel trained in emergency procedures prior to shipping bulk tankers.
Precautions During Transport: Secure containers, avoid rough handling. Inspect for leaks prior to shipment and on receipt at customer sites. National and international transport regulations frequently updated—compliance checked before every dispatch.
Major Regulatory Listings: Toluene regulated under the Globally Harmonized System (GHS), U.S. OSHA Hazard Communication Standard, REACH registration in the EU.
Restrictions: Some jurisdictions impose specific use and disposal restrictions. Direct marketing to consumer or residential settings unlikely due to flammability and chronic health risk profile. Production teams receive frequent legal updates and compliance training to meet evolving rules.
