Signs and Symptoms: Light hydrocarbon gases are simple asphyxiants and can cause anesthetic effects at high concentrations.
Symptoms of overexposure, which are reversible if exposure is stopped, can include shortness of breath, drowsiness, headaches,
confusion, decreased coordination, visual disturbances and vomiting. Continued exposure can lead to hypoxia (inadequate oxygen),
rapid breathing, cyanosis (bluish discoloration of the skin), numbness of the extremities, unconsciousness and death.
Other Comments: High concentrations may reduce the amount of oxygen available for breathing, especially in confined spaces.
Hypoxia (inadequate oxygen) during pregnancy may have adverse effects on the developing fetus.
The odorant, ethyl mercaptan, can be irritating to the eyes, skin and respiratory tract. At high concentrations, a person can temporarily
lose the ability to smell ethyl mercaptan. In addition, some individuals may have an impaired sense of smell, which inhibits the detection
of the odorant.
Pre-Existing Medical Conditions: Conditions which may be aggravated by exposure include respiratory (asthma-like) disorders.
Exposure to high concentrations of this material may increase the sensitivity of the heart to certain drugs. Persons with pre-existing
heart disorders may be more susceptible to this effect (see Section 4 - Note to Physicians).
See Section 11 for additional Toxicity Information.

4. First Aid Measures
Eye Contact: For contact with the liquefied gas, hold eyelids apart and gently flush the affected eye(s) with lukewarm water. Seek
immediate medical attention.
Skin Contact: Liquefied gases may cause cryogenic burns or injury. Treat burned or frostbitten skin by flushing or immersing the
affected area(s) in lukewarm water. Do not rub affected area. After sensation has returned to the frostbitten skin, keep skin warm, dry,
and clean. If blistering occurs, apply a sterile dressing. Seek immediate medical attention.
Inhalation (Breathing): If respiratory symptoms develop, move victim away from source of exposure and into fresh air in a position
comfortable for breathing. If symptoms persist, seek medical attention.
Ingestion (Swallowing): This material is a gas under normal atmospheric conditions and ingestion is unlikely.
Notes to Physician: Epinephrine and other sympathomimetic drugs may initiate cardiac arrhythmias in persons exposed to high
concentrations of hydrocarbon solvents (e.g., in enclosed spaces or with deliberate abuse). The use of other drugs with less
arrhythmogenic potential should be considered. If sympathomimetic drugs are administered, observe for the development of cardiac
arrhythmias.

________________________________________________________________________________________________
Unusual Fire & Explosion Hazards: Flammable. This material can be ignited by heat, sparks, flames, or other sources of ignition
(e.g., static electricity, pilot lights, mechanical/electrical equipment, and electronic devices such as cell phones, computers, calculators,
and pagers which have not been certified as intrinsically safe). Contents under pressure. Vapors may travel considerable distances to a
source of ignition where they can ignite, flash back, or explode. May create vapor/air explosion hazard indoors, in confined spaces,
outdoors, or in sewers. If container is not properly cooled, it can rupture in the heat of a fire. Closed containers exposed to extreme heat
can rupture due to pressure buildup. Drains can be plugged and valves made inoperable by the formation of ice if rapid evaporation of
large quantities of the liquefied gas occurs.
Extinguishing Media: Dry chemical or carbon dioxide is recommended. Carbon dioxide can displace oxygen. Use caution when
applying carbon dioxide in confined spaces.
Fire Fighting Instructions: For fires beyond the initial stage, emergency responders in the immediate hazard area should wear
protective clothing. When the potential chemical hazard is unknown, in enclosed or confined spaces, a self contained breathing
apparatus should be worn. In addition, wear other appropriate protective equipment as conditions warrant (see Section 8).
Isolate immediate hazard area and keep unauthorized personnel out. Stop spill/release if it can be done safely. If this cannot be done,
allow fire to burn. Move undamaged containers from immediate hazard area if it can be done safely. Stay away from ends of container.
Water spray may be useful in minimizing or dispersing vapors and to protect personnel. Cool equipment exposed to fire with water, if it
can be done safely.
Hazardous Combustion Products: Combustion may yield smoke, carbon monoxide, and other products of incomplete combustion.
See Section 9 for Flammable Properties including Flash Point and Flammable (Explosive) Limits
6. Accidental Release Measures
Personal Precautions: Flammable. Keep all sources of ignition and hot metal surfaces away from spill/release if safe to do so. The
use of explosion-proof electrical equipment is recommended. Stay upwind and away from spill/release. Notify persons and shipping
down wind of the spill/release, isolate immediate hazard area and keep unauthorized personnel out. Wear appropriate protective
equipment, including respiratory protection, as conditions warrant (see Section 8). See Sections 2 and 7 for additional information on
hazards and precautionary measures.
Environmental Precautions: Stop spill/release if it can be done safely. Water spray may be useful in minimizing or dispersing vapors.
If spill occurs on water notify appropriate authorities and advise shipping of any hazard.
Methods for Containment and Clean-Up: Notify relevant authorities in accordance with all applicable regulations.
7. Handling and Storage
Precautions for safe handling: Keep away from ignition sources such as heat/sparks/open flame ?No smoking. Use good personal
hygiene practices and wear appropriate personal protective equipment.
Gas can accumulate in confined spaces and limit oxygen available for breathing. Use only with adequate ventilation. Contents under
pressure. The use of explosion-proof electrical equipment is recommended and may be required (see appropriate fire codes). Refer to
NFPA-704 and/or API RP 2003 for specific bonding/grounding requirements. Do not enter confined spaces such as tanks or pits without
following proper entry procedures such as ASTM D-4276 and 29CFR 1910.146. Cold burns may occur during filling operations.
Containers and delivery lines may become cold enough to present cold burn hazard.
Propane and odorant are heavier than air and will collect and pool along the ground or floor. Odorant, therefore, may not be detectable
above the location of propane storage or service (for example, odorant in propane released or leaked into the basement of a dwelling
may not be detected above the basement).
WARNING - The intensity of the odorant may fade over prolonged storage or in the presence of rust, when placed initially in new or
freshly-cleaned storage vessels, or when exposed to masonry.
Conditions for safe storage: Keep container(s) tightly closed. Use and store this material in cool, dry, well-ventilated areas away from
heat, direct sunlight, hot metal surfaces, and all sources of ignition. Store only in approved containers. Post area "No Smoking or Open
Flame." Keep away from any incompatible material (see Section 10). Protect container(s) against physical damage. Avoid exposing any
part of a compressed-gas cylinder to temperatures above 125F(51.6C). Outdoor or detached storage is preferred. Gas cylinders should
be stored outdoors or in well ventilated storerooms at no lower than ground level and should be quickly removable in an emergency.

Note: State, local or other agencies or advisory groups may have established more stringent limits. Consult an industrial
hygienist or similar professional, or your local agencies, for further information.
Engineering controls: If current ventilation practices are not adequate to maintain airborne concentrations below the established
exposure limits, additional engineering controls may be required.
Eye/Face Protection: The use of eye protection (such as splash goggles) that meets or exceeds ANSI Z.87.1 is recommended when
there is potential liquid contact to the eye. Depending on conditions of use, a face shield may be necessary.
Skin/Hand Protection: Wear thermal insulating gloves and face shield or eye protection when working with materials that present
thermal hazards (hot or cold).
Respiratory Protection: A NIOSH approved, self-contained breathing apparatus (SCBA) or equivalent operated in a pressure demand
or other positive pressure mode should be used in situations of oxygen deficiency (oxygen content less than 19.5 percent), unknown
exposure concentrations, or situations that are immediately dangerous to life or health (IDLH).
A respiratory protection program that meets or is equivalent to OSHA 29 CFR 1910.134 and ANSI Z88.2 should be followed whenever
workplace conditions warrant a respirator's use.
Suggestions provided in this section for exposure control and specific types of protective equipment are based on readily
available information. Users should consult with the specific manufacturer to confirm the performance of their protective
equipment. Specific situations may require consultation with industrial hygiene, safety, or engineering professionals.

12. Ecological Information
Ecotoxicity: Petroleum gases will readily evaporate from the surface and would not be expected to have significant adverse effects in
the aquatic environment.
Mobility: Because of their extreme volatility, air is the only environmental compartment in which petroleum gases will be found. In air,
these hydrocarbons are photodegraded by reaction with hydroxyl radicals with half lives ranging from 7 days for propane to 3.2 days for
n-butane.
Persistence and degradability: The hydrocarbons in this material are expected to be inherently biodegradable. In practice,
hydrocarbon gases are not likely to remain in solution long enough for biodegradation to be a significant loss process. Hydrogen
sulfide, if present in refinery gas streams, will be rapidly oxidized in water and insoluble sulfides precipitated from water when metallic
radicals are present.
Bioaccumulation Potential: Since the log Kow values measured for refinery gas constituents are below 3, they are not regarded as
having the potential to bioaccumulate.
