3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
PROPANE IS A COLORLESS GAS OR LIQUID WITH A SLIGHT HYDROCARBON ODOR. IT IS SHIPPED OR
TRANSPORTED AS A LIQUIFIED GAS UNDER PRESSURE. IT IS EXTREMELY FLAMMABLE AND EXPLOSIVE. AT
HIGH CONCENTRATIONS THIS PRODUCT ACTS AS A SIMPLE ASPHYXIANT, WHICH DISPLACES OXYGEN FROM
THE BREATHNG ATMOSPHERE. MAY CAUSE SKIN AND EYE BURNS UPON LIQUID CONTACT. LARGE
RELEASES CAN CREATE A FLAMMABLE VAPOR CLOUD.
OSHA WARNING LABEL:
DANGER!
EXTREMELY FLAMMABLE.
LIQUID AND GAS UNDER PRESSURE.
LIQUID CAN CAUSE FROST BURNS.
CONSUMER WARNING LABEL:
A CONSUMER WARNING LABEL IS NOT APPLICABLE FOR THIS PRODUCT.
Inhalation: Product is an anesthetic at high concentrations, producing dizziness, headache,
incoordination and narcosis; extremely high concentrations can cause asphyxiation
and death by displacement of oxygen from the breathing atmosphere.
Ingestion: Ingestion not likely.
Skin contact: Vapor is generally non-irritating to skin. Direct contact with liquified product can
cause "cold burn" or frostbite.
Eye contact: Vapor is generally non-irritating to eyes. Direct contact with liquified product can
cause "cold burn" or frostbite.
Carcinogenic Evaluation:

Notes: The International Agency for Research on Cancer (IARC) has not evaluated this
product.
Component Information:
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.
Skin contact: If liquified product has caused a "frost burn", remove contaminated clothing. Thaw
frostbitten areas slowly with lukewarm water or by wrapping affected areas with
blankets. Do not rub affected areas. Let circulation reestablish itself naturally,
exercising area if possible. Call a physician.
Ingestion: Ingestion not likely. If swallowed, immediately call a physician.
MSDS ID NO.: 0194MAR001 Product name: Marathon Propane Page 2 of 8
Eye contact: Flush with large amounts of tepid water for at least 15 minutes. Immediately consult a
physician if frostbite is suspected (cloudy lens or greyish white tissue around the
eye).
Gas: Call a physician if symptoms or irritation occur.
Medical conditions aggravated Inhalation of high vapor concentrations of components of this product in animals has
by exposure: produced cardiac sensitization. Such sensitization may cause changes in heart
rhythms. This latter effect was shown to be enhanced by oxygen deficiency or the
injection of adrenalin-like agents.
5. FIRE FIGHTING MEASURES
Suitable extinguishing media: For small fires, Class B fire extinguishing media such as
CO2 or dry chemical can be used. For large fires use water
spray or fog. 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
gas/liquid per the OSHA Hazard Communication Standard,
and should be handled accordingly. For additional fire
related information see NFPA 30 or North American
Emergency Response Guide 115.
Special protective equipment for firefighters: Bleve`s (boiling liquid expanding vapor explosions) can
occur when a liquid in a pressurized container in close
proximity to a fire reaches a temperature well above its
boiling point. Its effect could lead to a catastrophic failure of
the vessel resulting in flying equipment fragments, a shock
wave and a fireball causing serious damage and death.
Isolate hazard area. If safe to do so, stop the flow of gas
and allow fire to burn out. Extinguishing the flame before
shutting off the supply can cause the formation of explosive
mixtures. In some cases it may be preferred to allow the
flame to continue to burn. Use extreme caution when fighting
liquefied petroleum gas fires. Keep surrounding area cool
with water spray from a distance and prevent further ignition
of combustible material. Avoid use of solid water streams.
Contact with water and liquified product can cause increased
vaporization.

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.
Leaking containers should be moved outdoors or to well-ventilated area and contents
transferred to a suitable container. Product vapor is heavier than air and can collect
in low areas that are without sufficient ventilation. Advise authorities and National
Response Center (800-424-8802) if the product has entered a water course or
sewer. Notify local health and pollution control agencies, if appropriate.

7. HANDLING AND STORAGE
Handling:
Product is stored as a liquid but used in the gaseous state. 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. Avoid overpressurizing or overfilling cylinders. Do not cut, drill, grind or weld on empty containers
since they may contain explosive residues.
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: Use atmosphere supplying respirators in the event of oxygen deficiency, when
material produces vapors that exceed permissible limits or when excessive 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: Wear insulated gloves to prevent skin contact and frostbite.
Eye protection: Use goggles or face-shield if there is a potential for splashing.
Hygiene measures: Use mechanical ventilation equipment that is explosion-proof.

Marathon Propane 74-98-6 >800,000 ppm for 15 min No data available No data available
[Rat]
Some of the major components of this product act as simple asphyxiant gases without significant potential for systemic
toxicity. At high concentrations these gases act as asphyxiants by diluting and displacing oxygen. Symptoms of persons
exposed to oxygen deficient atmospheres include headache, dizziness, incoordination, cyanosis and narcosis. Extremely
high concentrations can produce unconsciousness followed by death.
At extremely high concentrations and excessive exposure conditions components of this product may produce cardiac
sensitization.
