3. HAZARDS IDENTIFICATION
Potential Health Effects:
Eye: Contact with the liquefied or pressurized gas may cause momentary freezing followed by swelling and
eye damage.
Skin: Contact with the liquefied or pressurized gas may cause frostbite ("cold" burn). This material is a
gas under normal atmospheric conditions. No harmful effects from skin absorption are expected.
Inhalation (Breathing): Asphyxiant. High concentrations in confined spaces may limit oxygen
available for breathing. See Signs and Symptoms.
Ingestion (Swallowing): This material is a gas under normal atmospheric conditions and
ingestion is unlikely.
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), cyanosis (bluish discoloration of the skin), numbness
of the extremities, unconsciousness and death.

Inadequate data available to evaluate the cancer hazard of this material.
Cancer:
Target Organs: Inadequate data available for this material.
Developmental: Inadequate data available for this material.
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. Exposure during pregnancy to high concentrations of carbon monoxide or
carbon dioxide, which are produced during the combustion of hydrocarbon gases, can also cause harm to the
developing fetus.
This material contains mercaptans. Mercaptans are toxic gases with the smell of rotten cabbage. The
smell disappears rapidly because of olfactory fatigue. Therefore, odor may not be a reliable indicator
of exposure. Effects of overexposure include nausea, vomiting, irritation of the nose, throat and
digestive tract, signs of nervous system depression (e.g., headache, drowsiness, dizziness, loss of
coordination and fatigue), pulmonary edema, muscle weakness, convulsions, respiratory failure, coma and
death.
Pre-Existing Medical Conditions:
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).
4. FIRST AID MEASURES
Eye: For contact with the liquefied gas, hold eyelids apart and gently flush the affected eye(s) with
lukewarm water. Seek immediate medical attention.
Skin: Treat burned or frostbitten skin by flushing or immersing the affected area(s) in lukewarm water.
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. If symptoms persist, seek medical attention. If victim is not breathing, clear airway and immediately
begin artificial respiration. If breathing difficulties develop, oxygen should be administered by qualified
personnel. Seek immediate medical attention.
Ingestion (Swallowing): This material is a gas under normal atmospheric conditions and ingestion is unlikely.
Note To Physicians: 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.
5. FIRE FIGHTING MEASURES
Flash Point: -156癋/-104癈
Flammable Properties:
OSHA Flammability Class: Flammable Gas
LEL%: 2.1 / UEL%: 9.5
Autoignition Temperature: 842癋/432癈
Unusual Fire & Explosion Hazards: This material is flammable and can be ignited by heat, sparks, flames, or
other sources of ignition (e.g., static electricity, pilot lights, or mechanical/electrical equipment, and electronic
devices such as cell phones, computers, calculators, and pagers which have not been certified as intrinsically
Page 4 of 8
(MSDS: 169570)
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. Vapors are heavier than air and can accumulate in low areas. 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.
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 incipient stage, emergency responders in the immediate hazard
area should wear bunker gear. When the potential chemical hazard is unknown, in enclosed or confined spaces, or
when explicitly required by DOT, 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, keep unauthorized personnel out. Stop spill/release if it can be done with minimal
risk. If this cannot be done, allow fire to burn. Move undamaged containers from immediate hazard area if it can be
done with minimal risk.
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 with minimal risk.
6. ACCIDENTAL RELEASE MEASURES
Flammable. Keep all sources of ignition and hot metal surfaces away from spill/release. The use of
explosion-proof equipment is recommended.
Stay upwind and away from spill/release. Notify persons down wind of the spill/release, isolate immediate hazard
area and keep unauthorized personnel out. Stop spill/release if it can be done with minimal risk. Wear
appropriate protective equipment including respiratory protection as conditions warrant (see Section 8).
Notify fire authorities and appropriate federal, state, and local agencies. Water spray may be useful in
minimizing or dispersing vapors (see Section 5). If spill of any amount is made into or upon navigable waters, the
contiguous zone, or adjoining shorelines, notify the National Response Center (phone number 800-424-8802).
7. HANDLING AND STORAGE
Handling: Contents under pressure. The use of explosion-proof 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. The use of appropriate respiratory protection is advised when concentrations
exceed any established exposure limits (see Sections 2 and 8).
Use good personal hygiene practices.
"Empty" containers retain residue and may be dangerous. Do not pressurize, cut, weld, braze, solder, drill,
grind, or expose such containers to heat, flame, sparks, or other sources of ignition. They may explode and
cause injury or death. Containers should be disposed of in an environmentally safe manner and in accordance
with governmental regulations.
Before working on or in tanks which contain or have contained this material, refer to OSHA regulations, ANSI
Z49.1 and other references pertaining to cleaning, repairing, welding, or other contemplated operations.
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. Post area "No
Smoking or Open Flame." Store only in approved containers. Keep away from any incompatible material (see
Section 10). Protect container(s) against physical damage. Outdoor or detached storage is preferred.

(MSDS: 169570)
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering controls: If current ventilation practices are not adequate to maintain airborne concentrations below
the established exposure limits (see Section 2), additional engineering controls may be required. Where explosive
mixtures may be present, electrical systems safe for such locations must be used (see appropriate electrical
codes).
Personal Protective Equipment (PPE):
Respiratory: Wear a positive pressure air supplied respirator in situations where there may
be potential for airborne exposure above exposure limits (see Section 2). If exposure
concentration is unknown or if conditions immediately dangerous to life or health (IDLH)
exist, use a NIOSH approved self-contained breathing apparatus (SCBA) or equivalent
operated in a pressure demand or other positive pressure mode. A respiratory protection
program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements must be followed
whenever workplace conditions warrant a respirator's use.
Skin: The use of thermally resistant gloves is recommended.
Eye/Face: Approved eye protection to safeguard against potential eye contact, irritation, or
injury is recommended. Depending on conditions of use, a face shield may be necessary.
Other Protective Equipment: A source of clean water should be available in the work
area for flushing eyes and skin. Impervious clothing should be worn as needed.
Suggestions for the use of specific protective materials are based on readily available published
data. Users should check with specific manufacturers to confirm the performance of their products.

12. ECOLOGICAL INFORMATION
There is no information available on the ecotoxicological effects of petroleum gases. Because of
their high volatility, they are unlikely to cause ground or water pollution. Petroleum gases
released into the environment will rapidly disperse into the atmosphere and undergo photochemical
degradation.
13. DISPOSAL CONSIDERATIONS
This material, if discarded as produced, would be a RCRA "characteristic" hazardous waste due to the
characteristic(s) of ignitability (D001). If the spilled or released material impacts soil, water, or other
media, characteristic testing of the contaminated materials may be required prior to their disposal. Further,
this material, once it becomes a waste, is subject to the land disposal restrictions in 40 CFR 268.40 and may
require treatment prior to disposal to meet specific standards. Consult state and local regulations to
determine whether they are more stringent than the federal requirements.
Container contents should be completely used and containers should be emptied prior to discard. Container
rinsate could be considered a RCRA hazardous waste and must be disposed of with care and in full compliance
with federal, state and local regulations. Larger empty containers, such as drums, should be returned to the
distributor or to a drum reconditioner. To assure proper disposal of smaller empty containers, consult with
state and local regulations and disposal authorities.
