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. May Cause Flash Fire. Compressed gas. 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.
Signs of frostbite include a change in the color of the skin to gray or white,
possibly followed by blistering. 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 - Commercial 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. The burning of 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.

provide additional oxygen once breathing is restored if trained to do so. Seek
medical attention immediately.
Skin contact : Take off contaminated clothing and shoes immediately. Wash off immediately with
soap and plenty of water. Seek medical advice if symptoms persist or develop.
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 attention.
Ingestion : Ingestion is considered unlikely. If accidentally swallowed obtain immediate
medical attention.
Notes to physician : Symptoms: Dizziness, Headache, Nausea, Frostbite, Vomiting, Discomfort
SECTION 5. FIRE-FIGHTING MEASURES
2/9
Page 3 of 9
MATERIAL SAFETY DATA SHEET Propane - Commercial Grade
Form : Compressed liquefied gas
Flash point : -104 癈 (-155 癋)
Method: ASTM D 93
Auto Ignition temperature : 410 癈 (770 癋)
Lower explosive limit : 2.1 %(V)
Upper explosive limit : 9.5 % (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 : Keep people away from and upwind of spill/leak. Fire should not be extinguished
unless flow of gas can be immediately stopped. If spill or leak has not ignited,
determine if water spray may assist in dispersing gas or vapor to protect personnel
attempting to stop 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. Isolate area, particularly around ends of storage vessels. 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 and gas test area before
entering. 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. Do not flush
down sewer or drainage systems, unless system is designed and permitted to
handle such material.
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.
