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. If symptoms or irritation occur with
any exposure, call a physician.
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 Skin contact could aggravate an existing skin disorder or dermatitis condition.

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 combustible liquid
per the OSHA Hazard Communication Standard and should
be handled accordingly. 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 spray and foam
(AFFF/ATC) must be applied carefully to avoid frothing and
from as far a distance as possible. Avoid excessive water
spray application. Keep surrounding area cool with water
spray from a distance and prevent further ignition of
combustible material. Keep run-off water out of sewers and
water sources.

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:
MSDS ID NO.: 0252MAR019 Product name: Marathon Low Odor Base Solvent Page 3 of 8
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.
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.
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.
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
when significant vapors are generated. Observe respirator protection factor criteria
cited in ANSI Z88.2. Self-contained breathing apparatus should be used for fire
fighting.
Skin and body protection: Neoprene, nitrile, polyvinyl alcohol (PVA), polyvinyl chloride and polyurethane gloves
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: No special protective clothing is normally required. Select protective clothing
depending on industrial operations. Use mechanical ventilation equipment that is
explosion-proof.

11. TOXICOLOGICAL INFORMATION
Acute toxicity:
Product information
Name CAS Number Inhalation: Dermal: Oral:
Marathon Low Odor Base Solvent 64742-96-7 >3.6 mg/l [Rat] >3.16 gm/kg [Rabbit] >2 gm/kg [Rat]
Some components of this product, have been shown to produce a species specific, sex hormonal dependent kidney
lesion in male rats from repeated oral or inhalation exposure. Subsequent research has shown that the kidney damage
develops via the formation of a alpha-2碌-globulin, a mechanism unique to the male rat. Humans do not form alpha-2碌-
globulin, therefore, the kidney effects resulting from this mechanism are not relevant in humans.
Stoddard Solvent (Mineral Spirit) is an C9-C13 aliphatic naphtha hydrocarbon solvent (predominately normal, iso- and
cyclo-paraffins with <1.0% aromatics). Ninety day and two year inhalation studies of mineral spirits (stoddard solvent)
were conducted in mice and rats at concentrations of 138, 275, 550, 1,100 and 2,200 mg/m3. In the 90 day studies, no
significant toxicity was observed in rats except for nasel irritation at the highest dose and the previously noted effects in
the male rat kidney. No significant toxicity was observed in mice except for slight effects in the spleen of female mice. No
evidence of carcinogenic activity was observed in male mice or female rats chronically exposed to stoddard solvent.
There was equivocal evidence that stoddard solvent produced benign liver tumors in female mice (an effect associated
with increased body weight) and some evidence that stoddard solvent produced adrenal tumors in male rats. This latter
effect is believed to be a secondary response to the kidney disease mediated by alpha-2碌-microglobulin.
12. ECOLOGICAL INFORMATION
Ecotoxicity effects: The 96 hour LC50 of a water accomadated fraction (WAF) of mineral spirits is >1,000
mg/l in rainbow trout.
