SECTION 2. HAZARDS IDENTIFICATION
Emergency Overview
Regulatory status : This material is considered hazardous by the Occupational Safety and Health
Administration (OSHA) Hazard Communication Standard (29 CFR 1910.1200).
Signal Word : DANGER
Hazard Summary : Extremely flammable liquefied gas. Compressed gas May cause fire. Risk of
explosion if heated under confinement. High concentrations may exclude oxygen
and cause dizziness and suffocation. Contact with liquid or cold vapor may cause
frostbite or freeze burn.
Potential Health Effects
Eyes : Vapors are not irritating. Contact with liquid or cold vapor may cause frostbite or
freeze burn.
Skin : Vapors are not irritating. Direct contact to skin or mucous membranes with
liquefied product or cold vapor may cause freeze burns and frostbite. Contact to
mucous membranes with liquefied product may cause frostbite and freeze burns.
Contact can cause frostbite, freeze burns and/or chemical burns, resulting in
severe dermal damage. Skin may become inflamed and painful.
Ingestion : Ingestion is considered unlikely. Contact to mucous membranes with liquefied
product may cause frostbite and freeze burns.

MATERIAL SAFETY DATA SHEET Propane - Refinery Grade
Inhalation : This product is considered to be non-toxic by inhalation. Inhalation of high
concentrations may cause central nervous system depression such as dizziness,
drowsiness, headache, and similar narcotic symptoms, but no long-term effects.
Numbness, a "chilly" feeling, and vomiting have been reported from accidental
exposures to high concentrations. In high concentrations they will displace
oxygen from the breathing atmosphere, particularly in confined spaces. Signs of
asphyxiation will be noticed when oxygen is reduced to below 16%, and may
occur in several stages. Symptoms may include rapid breathing and pulse rate,
headache, dizziness, visual disturbances, mental confusion, incoordination,
mood changes, muscular weakness, tremors, cyanosis, narcosis and numbness
of the extremities. Unconsciousness leading to central nervous system injury
and possibly death will occur when the atmospheric oxygen concentration is
reduced to about 6% to 8% or less. Burning any hydrocarbon as a fuel in an
area without adequate ventilation may result in hazardous levels of combustion
products, including carbon monoxide, and inadequate oxygen levels, which may
cause unconsciousness, suffocation, and death.
Target Organs : Eyes, Skin, Central nervous system, Individuals with pre-existing conditions of
the heart, lungs, and blood may have increased susceptibility to symptoms of
asphyxia.

SECTION 4. FIRST AID MEASURES
Inhalation : If breathed in, move person into fresh air. If not breathing, give artificial
respiration. If necessary, provide additional oxygen once breathing is restored if
trained to do so. Seek medical attention immediately.
Skin contact : Take off all contaminated clothing immediately. Wash off with soap and water.
Obtain medical attention.
Eye contact : In case of eye contact, immediately flush with low pressure, cool water for at least
15 minutes, opening eyelids to ensure flushing. Seek medical advice.
Ingestion : Ingestion is considered unlikely. Seek medical attention immediately.
Notes to physician : Symptoms: Dizziness, Headache, Nausea, Frostbite, Vomiting, Discomfort
SECTION 5. FIRE-FIGHTING MEASURES
Form : Compressed liquefied gas
2/9
Page 3 of 9
MATERIAL SAFETY DATA SHEET Propane - Refinery Grade
Flash point : -104 癈 (-155 癋)
Method: ASTM D 93
Auto Ignition temperature : 410 癈 (770 癋)
Lower explosive limit : 2 % (V)
Upper explosive limit : 10 % (V)
Suitable extinguishing media : Water spray, Dry chemical, Foam, Carbon dioxide (CO2), Fire should not be
extinguished unless flow of gas can be immediately stopped.
Specific hazards during fire : Liquid releases flammable vapors at well below ambient temperatures and readily
fighting forms a flammable mixture with air. Dangerous fire and explosion hazard when
exposed to heat, sparks or flame. Vapors are heavier than air and may travel long
distances to a point of ignition and flash back. Container may explode in heat or
fire. Do not allow liquid runoff to enter sewers or public waters.
Special protective equipment : Firefighting activities that may result in potential exposure to high heat, smoke or
for fire-fighters toxic by-products of combustion should require NIOSH/MSHA- approved pressure-
demand self-contained breathing apparatus with full facepiece and full protective
clothing.
Further information : Refinery grade propane may be present in explosive or flammable concentrations
when there is no odor present. Keep people away from and upwind of spill/leak.
Fire should not be extinguished unless flow of gas can be immediately stopped.
Isolate area, particularly around ends of storage vessels. If a leak or spill has not
ignited, use water spray to disperse the vapors and to protect personnel
attempting to stop a leak. Use water to cool equipment, surfaces and containers
exposed to fire and excessive heat. For large fire the use of unmanned hose
holders or monitor nozzles may be advantageous to further minimize personnel
exposure. Major fires may require withdrawal, allowing the tank to burn. Withdraw
immediately in the event of a rising sound from a venting safety device. Large fires
typically require specially trained personnel and equipment to isolate and
extinguish the fire.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions : Evacuate nonessential personnel and remove or secure all ignition sources. No
road flares, smoking or flames in hazard area. Consider wind direction; stay
upwind and uphill, if possible. Evaluate the direction of product travel, diking,
sewers, etc. to contain spill areas. Vapor cloud may be white, but color will
dissipate as cloud disperses - fire explosion, and toxic hydrogen sulfide gas hazard
may be present after visible cloud is dispersed. Ventilate the area. Do not touch
spilled liquid (frostbite/freeze burn hazard!).
Environmental precautions : Carefully contain and stop the source of the spill, if safe to do so. Ventilate and gas
test area before entering. Do not flush into surface water or sanitary sewer system.
Methods for cleaning up : The product evaporates readily. Consider the use of water spray to disperse gas or
vapors. Isolate area until gas has dispersed.
