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 Pre-existing eye, skin, respiratory, liver and/or kidney disorders may be aggravated
by exposure: by exposure 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 128.
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.

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. Avoid skin contact. Exercise good personal hygiene
including removal of soiled clothing and prompt washing with soap and water.
For use as a motor fuel only. Product should never be used as a solvent due to its flammable and potentially toxic
properties. Siphoning by mouth can result in lung aspiration which can be harmful or fatal.
Portable containers of 12 gallons (45 liters) or less should never be filled while they are in or on a motor vehicle or marine
craft. Static electric discharge can ignite fuel vapors when filling non-grounded containers or vehicles on trailers.
Containers should be placed on the ground. The nozzle spout must be kept in contact with the container before and
during the entire filling operation. Use only approved containers. A buildup of static electricity can occur upon re-entry
into a vehicle during fueling especially in cold or dry climate conditions. The charge is generated by the action of
dissimilar fabrics (i.e., clothing and upholstery) rubbing across each other as a person enters/exits the vehicle. A flash fire
can result from this discharge if sufficient flammable vapors are present. Therefore, do not get back in your vehicle while
refueling. Cellular phones and other electronic devices may have the potential to emit electrical charges (sparks). Sparks
in potentially explosive atmospheres (including fueling areas such as gas stations) could cause an explosion if sufficient
flammable vapors are present. Therefore, turn off cellular phones and other electronic devices when working in
potentially explosive atmospheres or keep devices inside your vehicle during refueling.
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: Use nitrile rubber, viton or PVA gloves for repeated or prolonged skin exposure.
Eye protection: No special eye protection is normally required. Where splashing is possible, wear
safety glasses with side shields.
Hygiene measures: No special protective clothing is normally required. Select protective clothing
depending on industrial operations. Use mechanical ventilation equipment that is
explosion-proof.

Gasoline
MSDS ID NO.: 0125MAR019 Product name: Marathon Mid Grade Unleaded Page 7 of 15
Gasoline
Lifetime inhalation studies with full vaporized gasoline (67, 292 and 2,056 ppm) produced kidney damage and kidney
tumors in male rats but not in female rats or male and female mice. Female mice developed a slightly higher incidence of
liver tumors compared to controls at the highest exposure level. Results from separate studies with compounds
producing similar effects, i.e., 1,4-dichlorobenzene and perchloroethylene, have shown that the kidney damage and
kidney tumors develop via the formation of alpha-2u-globulin, a mechanism unique to the male rat. Humans do not form
alpha-2u-globulin, therefore, tumors resulting from this mechanism are not relevant in humans. The biologic significance
of the mouse liver tumor response with regard to human health risk is questionable.
Summary of health effect information on gasoline engine exhaust:
Chronic inhalation studies of gasoline engine exhaust in mice, rats and hamsters did not produce any carcinogenic
effects. Condensates/extracts of gasoline engine exhaust produced an increase in tumors compared to controls when
testing by skin painting, subcutaneous injection, intratracheal instillation or implantation into the lungs. Combustion of
gasoline produces gases and particulates which include carbon monoxide, carbon dioxide, oxides of nitrogen and/or
sulfur and hydrocarbons. Significant exposure to carbon monoxide vapors decreases the oxygen carrying capacity of the
blood and may cause tissue hypoxia via formation of carboxyhemoglobin. Overexposure to CO can cause headache,
nausea, nervous system depression, coma and death.
Summary of health effect data on gasoline components:
This product contains benzene at a level of >0.1%. Repeated or prolonged exposure to benzene at concentrations in
excess of the TLV may cause serious injury to blood-forming organs. Significant chronic exposure to benzene vapor has
been reported to produce various blood disorders ranging from anemia to certain forms of leukemia (cancer) in man.
Benzene produced tumors in rats and mice in lifetime chronic toxicity studies, but the response has not been consistent
across species, strain, sex or route of exposure. Animal studies on benzene have demonstrated immune toxicity,
chromosomal aberrations, testicular effects and alterations in reproductive cycles and embryo/fetotoxicity, but not
teratogenicity.
This product contains >0.1% ethyl benzene (EB). Rats and mice exposed to 750 ppm EB for 6 hours/day, 5 days/week
for two years developed kidney tumors in male and femmale rats and lung tumors in male mice and liver tumor in female
mice.
This product contains >0.1% naphthalene. Exposure to naphthalene at 30 ppm for two years caused lung tumors in
female mice. Male mice with the same exposure did not develop tumors. Exposure to 10-60 ppm naphthalene for 2 years
caused tumors in the tissue lining of the nose and respiratory tract in male and female rats. Oral administration of 133-
267 mg/kg/day of naphthalene in mice for up to 90 days did not produce mortality, systemic toxicity, adversely affect
organ or body weight or produce changes in blood. Repeated oral administration of naphthalene produced an anemia in
dogs. Repeated intraperitoneal doses of naphthalene produced lung damage in mice. Repeated high doses of
naphthalene has caused the formation of cataracts and retinotoxicity in the eyes of rats and rabbits due to accumulation
of 1,2-naphthoquinone, a toxic metabolite. Effects in human eyes is uncertain and not well documented. Pregnant rats
administered intraperitoneal doses of naphthalene during gestation gave birth to offspring that had delayed heart and
bone development. Pregnant mice given near lethal doses of naphthalene showed no significant maternal toxicity and a
reduction in the number of pups per litter, but no gross abnormalities in offspring. Suppressed spermatogenesis and
progeny development have been reported in mice, rats and guinea pigs after exposure to high concentrations of
naphthalene in their drinking water. Certain groups or individuals, i.e., infants, Semites, Arabs, Asians and Blacks, with a
certain blood enzyme deficiency (glucose-6-phosphate dehydrogenase) are particularly susceptible to hemolytic agents
and can rapidly develop hemolytic anemia and systemic poisoning from ingestion or inhalation of naphthalene.
This product may contain hexane at a level of >1.0%. Studies in laboratory animals have produced systemic toxicity in
blood, spleen and lungs. Fetotoxicity has been observed at hexane concentrations that produced maternal toxicity.
Long term exposure to high concentrations of hexane has been shown to cause testicular effects and nervous system
damage.
