3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
TOLUENE IS A COLORLESS LIQUID WITH A STRONG HYDROCARBON ODOR. IT IS A VOLATILE AND
EXTREMELY FLAMMABLE LIQUID THAT MAY CAUSE FLASH FIRES. KEEP AWAY FROM HEAT, SPARKS AND
OPEN FLAME. NEVER SIPHON THIS PRODUCT BY MOUTH. IF SWALLOWED, THIS PRODUCT MAY GET
SUCKED INTO THE LUNGS (ASPIRATED) AND CAUSE LUNG DAMAGE OR EVEN DEATH.
OSHA WARNING LABEL:
DANGER!
EXTREMELY FLAMMABLE.
ASPIRATION (INADVERTENT SUCTION) OF LIQUID INTO THE LUNGS CAN PRODUCE CHEMICAL PNEUMONIA
OR EVEN DEATH.
CONSUMER WARNING LABEL:
A CONSUMER WARNING LABEL IS NOT APPLICABLE FOR THIS PRODUCT.
Inhalation: Overexposure or prolonged exposure to lower concentrations can cause respiratory
irritation. Gross overexposure can cause central nervous system depression,
producing symptoms of headache, dizziness, narcosis, and muscular incoordination.
Excessive product exposure may cause cardiac sensitization.
Ingestion: Liquid ingestion causes severe gastrointestinal pain, abdominal cramps, nausea,
vomiting, narcosis and central nervous system depression. Aspiration (inadvertent
suction) of liquid into the lungs must be avoided as even small quantities in the lungs
can produce chemical pneumonitis, pulmonary edema/hemorrhage and even death.
Skin contact: Prolonged and repeated liquid contact can cause defatting and drying of the skin and
can lead to irritation and/or dermatitis.
Eye contact: Eye irritation may result from contact with the liquid or exposure to the vapor at
concentrations above the TLV.

4. FIRST AID MEASURES
Inhalation: If affected, move person to fresh air. If breathing is difficult, administer oxygen. If not
breathing or if no heartbeat, give artificial respiration or cardiopulmonary
resuscitation (CPR). Immediately call a physician.
MSDS ID NO.: 0157MAR019 Product name: Marathon Toluene Page 2 of 7
Skin contact: Wash with soap and large amounts of water. Remove contaminated clothing. If
symptoms or irritation occur, call a physician.
Ingestion: If swallowed, do not induce vomiting and do not give liquids. Immediately call a
physician.
Eye contact: Flush eyes with large amounts of tepid water for at least 15 minutes. If symptoms or
irritation occur, call a physician.
Medical conditions aggravated by Pre-existing skin conditions and respiratory disorders may be aggravated by
exposure: exposures to components of this product.
5. FIRE FIGHTING MEASURES
Suitable extinguishing media: For small fires, Class B fire extinguishing media such as
CO2, dry chemical, foam (AFFF/ATC) or water spray can be
used. For large fires, water spray, fog or foam (AFFT/ATC)
can be used. Fire fighting should be attempted only by those
who are adequately trained and equipped with proper
protective equipment.
Specific hazards: This product has been determined to be a flammable liquid
per the OSHA Hazard Communication Standard, and should
be handled accordingly. Vapors may travel along the
ground or be moved by ventilation and ignited by many
sources such as pilot lights, sparks, electric motors, static
discharge, or other ignition sources at locations distant from
material handling. Flashback can occur along vapor trail.
For additional fire related information, see NFPA 30 or the
North American Emergency Response Guide 130.
Special protective equipment for firefighters: Avoid using straight water streams. Water may be
ineffective in extinguishing low flash point fires, but can be
used to cool exposed surfaces. Avoid excessive water spray
application. Water spray and foam (AFFF/ATC) must be
applied carefully to avoid frothing and from as far a distance
as possible. Keep run-off water out of sewers and water
sources.

Other: - Special: *See Section 8 for guidance in selection of
personal protective equipment.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions: Keep public away. Isolate and evacuate area. Shut off source if safe to do so.
Eliminate all ignition sources. Advise authorities and National Response Center (800-
424-8802) if substance has entered a watercourse or sewer. Notify local health and
pollution control agencies, if appropriate. Contain liquid with sand or soil. Recover
and return free product to proper containers. Use suitable absorbent materials such
as vermiculite, sand, or clay to clean up residual liquids.

7. HANDLING AND STORAGE
Handling:
Comply with all applicable EPA, OSHA, NFPA and consistent state and local requirements. Use appropriate grounding
and bonding practices. Store in properly closed containers that are appropriately labeled and in a cool well-ventilated
area. Do not expose to heat, open flames, strong oxidizers or other sources of ignition. Do not cut, drill, grind or weld on
empty containers since they may contain explosive residues.
Never siphon this product by mouth. Avoid repeated and prolonged skin contact. Exercise good personal hygiene
including removal of soiled clothing and prompt washing with soap and water.
Hydrocarbons are basically non-conductors of electricity and can become electrostatically charged during mixing, filtering,
pumping at high flow rates or loading and transfer operations. If this charge reaches a sufficiently high level, sparks can
form that may ignite the vapors of flammable liquids. Sudden release of hot organic chemical vapors or mists from
process equipment operating under elevated temperature and pressure, or sudden ingress of air into vacuum equipment
may result in ignitions without the presence of obvious ignition sources. Nozzle spouts must be kept in contact with the
containers or tank during the entire filling operation.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
PERSONAL PROTECTIVE EQUIPMENT
Engineering measures: Local or general exhaust required in an enclosed area or when there is inadequate
ventilation.
Respiratory protection: Approved organic vapor chemical cartridge or supplied air respirators should be worn
for exposures to any components exceeding the TLV or STEL. Observe respirator
protection factor criteria cited in ANSI Z88.2. Self-contained breathing apparatus
should be used for fire fighting.
Skin and body protection: Viton gloves should be used to prevent skin contact.
Eye protection: No special eye protection is normally required. Where splashing is possible, wear
safety glasses with side shields.
Hygiene measures: Use mechanical ventilation equipment that is explosion-proof.

11. TOXICOLOGICAL INFORMATION
Acute toxicity:
Product information
Name CAS Number Inhalation: Dermal: Oral:
Marathon Toluene 108-88-3 LC50 = 3388-8800 ppm LD50 = 14.1 ml/kg LD50 = 5.5-7.5 gm/kg
for 4 hrs [Rats] [Rabbit] [Rat]
Toluene was not carcinogenic in mice and rats exposed in a 2 year inhalation study for 6 hours/day, 5 days/week at
concentrations of 600 or 1200 ppm.
Exposure to pregnant rats and mice during gestation to toluene produced some maternal and development toxicity
(decreased fetal weight and increased sleletal variations). Toluene produced a mid frequency hearing loss in rats
subchronically exposed to high concentrations of toluene. Decreased learning capability and deficits in operant behavior
have been observed in animals subjected to exposure regimens that generally exceed established exposure limits.
Deliberate inhalation of high concentrations of toluene has been shown to cause liver, kidney and brain damage and
central nervous system effects (incoordination, lassitude and memory loss) in individuals abusing toluene for its euphoric
effects.
12. ECOLOGICAL INFORMATION
Ecotoxicity effects: The 96 hour LC50 for toluene ranges from 5.4 to 26 mg/l in fathead minnow and
salmon. The 48 hour ED50 for toluene is 11.5 mg/l in daphnia. The 96 hour No
Observed Effect Concentration (NOEC) of toluene in algae is 10 mg/l. This product
does not concentrate or accumulate in the food chain.
13. DISPOSAL CONSIDERATIONS
Cleanup Considerations: This product as produced is not specifically listed as an EPA
RCRA hazardous waste according to federal regulations (40
CFR 261). However, when discarded or disposed of, it may
meet the criteria of an "characteristic" hazardous waste. This
product could also contain benzene at >0.5 ppm and could
exhibit the characteristics of "toxicity" as determined by the
toxicity characteristic leaching procedure (TCLP). This
material could become a hazardous waste if mixed or
contaminated with a hazardous waste or other substance(s).
It is the responsibility of the user to determine if disposal
material is hazardous according to federal, state and local
