EMERGENCY OVERVIEW
DENATURED ALCOHOL IS A CLEAR, COLORLESS LIQUID WITH A HYDROCARBON ODOR. IT CONTAINS 95%
ETHYL ALCOHOL. 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!
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: Prolonged breathing of high ethanol vapor concentrations can produce headache,
dizziness, nausea, incoordination and impaired vision. Excessive overexposure can
cause central nervous system depression, loss of consciousness, liver damage and
death resulting from respiratory failure.
Ingestion: Liquid ingestion can cause inebriation, headache, incoordination, gastrointestinal
pain, nausea, and vomiting leading to 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: Liquid is practically non-irritating to the skin. Prolonged and repeated liquid contact
can cause defatting and drying of the skin and can lead to irritation and/or dermatitis.
Eye contact: Liquid may cause mild to severe irritation. Splash contact or high vapor
concentrations can produce an immediate burning and stinging sensation.

Notes: The International Agerncy for Research on Cancer (IARC) has determined that there
is inadequate evidence for the carcinogenicity of gasoline in humans. IARC
determined that limited evidence of carcinogenicity in animals exists. IARC's overall
evaluation of gasoline, in spite of limited carcinogenicity evidence, has resulted in the
IARC designation of gasoline as possibly carcinogenic to humans (Group 2B)
because gasoline contains benzene.
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. 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 Pre-existing eye, skin, respiratory disorders and impaired liver function may be
exposure: aggravated by overexposure to ethanol. Persons on disulfiram (antabuse) therapy
should be aware that the ethyl alcohol in the product is hazardous to them just as is
alcohol from any source. Disulfiram reactions (vomiting, headache and even
collapse) may follow ingestion of small amounts of alcohol.
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 127.
Special protective equipment for firefighters: Flame is invisible in daylight. 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.
Flash point: <-5 F
Autoignition temperature: No data available.

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. 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. 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
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: 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.

Intentional abuse, misuse or other massive exposure to ethanol may result in multiple organ damage and/or death.
Chronic ingestion of large amounts of ethanol can cause cancer and damage to the liver, kidney, heart, brain, nervous
system and stomach. Ethyl alcohol ingestion during pregnancy can adversely affect the unborn child. Studies in
laboratory animals involving prolonged and repeated exposures have resulted in such effects as embryotoxicity,
immunotoxicity and teratogenicity. Mutagenic effects have been reported in both in vitro and in vivo systems but usually
at high dosages.
This product may contain natural gasoline at a level of >1.0%. Repeated dermal application has produced severe
irritation and systemic toxicity in subacute toxicity studies. Some components of this product, i.e., paraffins and olefins,
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 alpha-2u-
globulin, a mechanism unique to the male rat. Humans do not form alpha-2u-globulin, therefore, the kidney effects
resulting from this mechanism are not relevant in humans. Some components were found to be positive in a few
mutagenicity tests while negative in the majority of others. The exact relationship between these results and human
health is not known.
