CELL: 391-8260
Transportation Emergency:
CHEMTRAC @ 1-(800) 424-9300
Extremely
flammable liquefied gas under pressure. Keep away from heat, sparks, flame,
and all other ignition sources. Vapor reduces oxygen available for breathing
and may cause suffocation in confined spaces. Use only with adequate ventilation.
Odor may not provide adequate warning of potentially hazardous concentrations.
Vapor is heavier than air and may collect at low levels. Liquid may cause freeze
burn similar to frostbite. Do not get liquid in eyes, on skin, or on clothing.
Avoid prolonged breathing of vapor. Keep container valve closed when not in
use.

Inhalation:
Asphyxiant in high concentrations due to dilution of available oxygen. At excessive
vapor concentrations, this product has anesthetic, asphyxiating properties and
may cause sleepiness. At levels above 100,000 ppm (i.e. 10%), propane is mildly
irritating to the respiratory tract and may result in dizziness, headache, drowsiness,
nausea, shortness of breath, muscular in coordination, excessive salivation,
disorientation, vomiting, and excitation. In extreme cases, convulsions, unconsciousness
and death may occur as a result of asphyxiation. Persons with chronic respiratory
disease should avoid exposure.
Ingestion: Liquid may cause freeze burn similar to frostbite. Ingestion not expected to occur in normal use.
Eye Contact: Liquid may cause freeze burn similar to frostbite.
Skin contact: Liquid may cause freeze burn similar to frostbite.
Other: Product is not listed by IARC, NTP or OSHA as a potential carcinogen. Propane and some of the minor components have been reported to be cardiac sensitizers in experiments.

Section
V Emergency and First Aid Procedure for Overexposure by
Inhalation: Remove victim from further exposure and into fresh air. Provide oxygen if breathing is difficult. If victim is unconscious, get prompt medical attention.
Ingestion: If swallowed, get immediate medical attention.
Eye Contact: For contact with liquid, flush immediately with water. Obtain immediate medical attention.
Skin Contact: If freeze burn occurs, remove contaminated clothes, shoes and jewelry. Immerse burned area in warm (not hot) water. Keep immersed. Get prompt medical attention.
Boiling Point: -44¡F
Melting Point: N/A
Vapor Pressure: 196 psig @ 100¡F
Specific Gravity: 0.504
Vapor Density: -1.50
Solubility in Water: Slight, 0.1 to 1.0%
Appearance & Order:
Colorless, odorless in natural form.
Odorant Warning: Odorant is added to aid in detection of leaks. One common odorant is ethyl mercaptan, CAS No. 75-08-1. Odorant has a foul, skunk-like odor. The odorant is effective in most instances, but not everyone can smell the odor. The ability of people to detect odors varies widely. Also, certain chemical reactions with material in the propane system can reduce the propane odor level. No odorant will be 100% effective in all circumstances. If odor level appears to be weak, notify propane supplier immediately.
Flash Point & Method Used: -156¡F (estimated)
Ignition Temperature in Air: 920 TO 1120¡F
Flammable Limits in Air: LOWER--2.2% UPPER--9.6%
NFPA Rating: (Under Fire Conditions. Does not apply to exposure hazards other than during fire)
Health: 1 Slightly toxic
Fire: 4 Extremely flammable
Reactivity: 0 Stable
Fire Fighting Procedures: Eliminate sources of ignition. Evacuate area. Notify fire department. Allow only trained, properly protected Personnel in area. Shut off source of gas, if possible. Allow fire to burn itself out after gas flow is shut off. If gas flow cannot be shut off, do not extinguish fire. Allow fire to burn itself out using high volume water supply to cool heat-exposed pressure containers and nearby equipment. Approach a flame-enveloped container from the side, never the head ends. Use extreme caution when applying water to a container which has been exposed to heat or flame for more than a short time. For uncontrollable fires and when flame is impinging on container, withdraw all personnel and evacuate vicinity immediately
Usual Fire and Explosion Hazards: Firefighters should wear self-contained breathing apparatus in the positive pressure mode with a full-face piece when there is a possibility of exposure to smoke, fumes or hazardous decomposition products. Uncontrolled vapors spread rapidly, are heavier than air and are extremely flammable.
Stability: Stable
Hazardous Polymerization: Will not occur
Conditions & Materials To Avoid: Keep away from high heat, sparks, open flame, strong oxidizing agent .
Hazardous Decomposition Products: Incomplete combustion may yield carbon monoxide, a toxic gas.
Environmental Effects: Avoid uncontrolled releases of this material. Liquid release will have possible effect on plant and animal life. Large liquid release will quickly vaporize to produce vapor cloud. Vapor cloud is both a fire and asphyxiation hazard.
Spill
or Leak Procedures:
Product is extremely flammable. Vapor is heavier than air and may collect at
lower levels. Flammable concentrations may be present below nose level. If there
is a leak but no fire, do not ignite the escaped gas. Eliminate all ignition
sources. Do not smoke, use a nearby phone or turn electrical switches on and
off. Evacuate area. If possible, remove leaking container to safe area. Stop
flow of gas or allow vapor to disperse in a safe area. Water spray can be used
to help dilute vapor concentration in air.
Control Measures: Use local and dilution ventilation to maintain exposures below acceptable criteria
Respiratory Protections: If concentrations are high enough to warrant supplied-air or self-contained breathing apparatus, atmosphere may be flammable (see Section VII). Appropriate precautions must be taken regarding flammability. For situations where flammability has been safely addressed and where control measures are not feasible or sufficient to achieve full conformance with acceptable criteria (Section IV), use NIOSH/MSHA approved respiratory protection (supplied-air or self-contained breathing apparatus as appropriate). Respirators should be selected based on form and concentration of contaminant in air and in accordance with OSHA (29 CFR 1910.134).
Protective Clothing: Avoid skin contact with liquid because of possibility of freeze burn. Wear gloves and protective clothing which are impervious to the product for the duration of the anticipated exposure.
Eye Protection: Use chemical safety goggles meeting the specifications of ANSI Z87.1 when connecting or disconnecting lines under pressure. Spectacle type safety glasses do not provide satisfactory protection
Waste Disposal: Dispose of gas in accordance with applicable laws and regulations. When permitted, vent vapor in a safe location and insure that gas dissipates below the lower flammable limit. Controlled burning is preferred.

Store in an authorized location
(outside, detached storage is preferred with adequate ventilation. Isolate from
heat and ignition sources. Isolate from combustible materials. Provide separate
storage locations for other compressed or flammable gases. Inspect cylinders
frequently for leaks, dents, gouges and corrosion with emphasis on bottom of
cylinder. Store cylinders in upright position or with pressure relief valves
in vapor space. Do not drop or abuse cylinders. Keep container valve closed
and plugged when not in use. Install protective caps when cylinders are not
connected for use. Empty containers retain some residue, so they should be treated
as if they were full
