The Chemical Identifier fields include common identification numbers, the NFPA diamond U.S. Department of Transportation hazard labels, and a general description of the chemical. The information in CAMEO Chemicals comes from a variety of data sources. CAS Number UN/NA Number DOT Hazard Label USCG CHRIS Code 108-88-3 1294 Flammable Liquid TOL NIOSH Pocket Guide International Chem Safety Card Toluene TOLUENE NFPA 704 Diamond Hazard Value Description 3 2 0 Health 2 Can cause temporary incapacitation or residual injury. Flammability 3 Can be ignited under almost all ambient temperature conditions. Instability 0 Normally stable, even under fire conditions. Special (NFPA, 2010) General Description A clear colorless liquid with a characteristic aromatic odor. Flash point 40掳F. Less dense than water (7.2 lb / gal) and insoluble in water. Hence floats on water. Vapors heavier than air. May be toxic by inhalation, ingestion or skin contact. Used in aviation and automotive fuels, as a solvent, and to make other chemicals. Hazards What is this information? The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources. Reactivity Alerts Highly Flammable Air & Water Reactions Highly flammable. Insoluble in water. Fire Hazard Behavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. (USCG, 1999) Health Hazard Vapors irritate eyes and upper respiratory tract; cause dizziness, headache, anesthesia, respiratory arrest. Liquid irritates eyes and causes drying of skin. If aspirated, causes coughing, gagging, distress, and rapidly developing pulmonary edema. If ingested causes vomiting, griping, diarrhea, depressed respiration. (USCG, 1999) Reactivity Profile TOLUENE reacts vigorously with allyl chloride or other alkyl halides even at -70掳C in the presence of ethyl aluminum dichloride or ethyl aluminum sesquichloride. Explosions have been reported [NFPA 491M 1991]. Incompatible with strong oxidizing agents. When added to a tank of sulfur dichloride, the tank over pressurized and ruptured in a reaction thought to be catalyzed by iron or iron(III) chloride [Chem. Eng. News, 1988, 66(32), 2]. Belongs to the Following Reactive Group(s) Hydrocarbons, Aromatic Potentially Incompatible Absorbents

Response Recommendations What is this information? The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid. The information in CAMEO Chemicals comes from a variety of data sources. Isolation and Evacuation Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]: IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions. LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet). FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020) Firefighting Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]: CAUTION: The majority of these products have a very low flash point. Use of water spray when fighting fire may be inefficient. SMALL FIRE: Dry chemical, CO2, water spray or regular foam. LARGE FIRE: Water spray, fog or regular foam. Avoid aiming straight or solid streams directly onto the product. If it can be done safely, move undamaged containers away from the area around the fire. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2020) Non-Fire Response Excerpt from ERG Guide 130 [Flammable Liquids (Water-Immiscible / Noxious)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean, non-sparking tools to collect absorbed material. LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2020) Protective Clothing Excerpt from NIOSH Pocket Guide for Toluene: Skin: PREVENT SKIN CONTACT - Wear appropriate personal protective clothing to prevent skin contact. Eyes: PREVENT EYE CONTACT - Wear appropriate eye protection to prevent eye contact. Wash skin: WHEN CONTAMINATED - The worker should immediately wash the skin when it becomes contaminated. Remove: WHEN WET (FLAMMABLE) - Work clothing that becomes wet should be immediately removed due to its flammability hazard (i.e., for liquids with a flash point ERPGs (Emergency Response Planning Guidelines) Chemical ERPG-1 ERPG-2 ERPG-3 Toluene (108-88-3) 50 ppm 300 ppm 1000 ppm indicates that odor should be detectable near ERPG-1. (AIHA, 2022) PACs (Protective Action Criteria) Chemical PAC-1 PAC-2 PAC-3 Toluene (108-88-3) 67 ppm 560 ppm 3700 ppm LEL = 14000 ppm indicates value is 10-49% of LEL. (DOE, 2018) Regulatory Information What is this information? The Regulatory Information fields include information from the U.S. Environmental Protection Agency's Title III Consolidated List of Lists, the U.S. Cybersecurity and Infrastructure Security Agency's Chemical Facility Anti-Terrorism Standards, and the U.S. Occupational Safety and Health Administration's Process Safety Management of Highly Hazardous Chemicals Standard List (see more about these data sources).
