3. HAZARDS IDENTIFICATION (rev. Aug-98; Tox-98)
EMERGENCY OVERVIEW
DANGER!
EXTREMELY FLAMMABLE GAS - MAY CAUSE FLASH FIRE OR EXPLOSION!
High concentrations may exclude oxygen and cause dizziness and suffocation. Contact with pressurized
vapor may cause frostbite or freeze burn.
EYES
Not irritating. However, contact with pressurized vapor may cause frostbite, freeze burns, and permanent
eye damage.
SKIN
Not irritating. Direct contact to skin or mucous membranes with pressurized vapor may cause freeze
burns and frostbite. 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
Risk of ingestion is extremely unlikely.
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.

MATERIAL SAFETY DATA SHEET
NATURAL GAS (odorized) MSDS No. 8010
This product is a simple asphyxiant. In high concentrations it 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.
WARNING: 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.
CHRONIC and CARCINOGENICITY
None expected - see Section 11.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
Individuals with pre-existing conditions of the heart, lungs, and blood may have increased susceptibility to
symptoms of asphyxia.
4. FIRST AID MEASURES (rev. Aug-98; Tox-98)
EYES
In case of freeze burn cover eyes to protect from light. Seek immediate medical attention.
SKIN
In case of frostbite or freeze burns seek immediate medical attention.
INGESTION
Though risk of ingestion is extremely unlikely, in case of frostbite or freeze burns due to oral exposure
seek immediate medical attention.
INHALATION
Remove person to fresh air. If person is not breathing, provide artificial respiration. If necessary, provide
additional oxygen once breathing is restored if trained to do so. Seek medical attention immediately.
5. FIRE FIGHTING MEASURES (rev. Aug-98)
FLAMMABLE PROPERTIES: (NFPA Natural Gas)
FLASH POINT: Flammable gas
o o
AUTOIGNITION POINT: 900 - 1170 F (482 - 632 C)
OSHA/NFPA FLAMMABILITY CLASS: FLAMMABLE GAS
LOWER EXPLOSIVE LIMIT (%): 3.8 - 6.5
UPPER EXPLOSIVE LIMIT (%): 13 - 17
FIRE AND EXPLOSION HAZARDS
Dangerous fire and explosion hazard when exposed to heat, sparks or flame. Natural gas is lighter than
air and may travel long distances to a point of ignition and flash back. Container may explode in heat or
fire. Liquefied Natural Gas (LNG) releases flammable gas at well below ambient temperatures and readily
forms a flammable mixture with air.
EXTINGUISHING MEDIA
Dry chemical, carbon dioxide, Halon or water. However, fire should not be extinguished unless flow of gas
can be immediately stopped.
FIRE FIGHTING INSTRUCTIONS
Gas fires should not be extinguished unless flow of gas can be immediately stopped. Shut off gas source
and allow gas to burn out. 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.
Revision Date: 08/12/98 Page 2 of 6
MATERIAL SAFETY DATA SHEET
NATURAL GAS (odorized) MSDS No. 8010
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. Let vessel, tank car or container burn unless
leak can be stopped. 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.
Firefighting activities that may result in potential exposure to high heat, smoke or toxic by-products of
combustion should require NIOSH/MSHA- approved pressure-demand self-contained breathing apparatus
with full facepiece and full protective clothing.
See Section 16 for the NFPA 704 Hazard Rating.
6. ACCIDENTAL RELEASE MEASURES (rev. Aug-98)
ACTIVATE FACILITY'S SPILL CONTINGENCY or EMERGENCY RESPONSE PLAN.
Evacuate nonessential personnel and secure all ignition sources. No road flares, smoking or flames in
hazard area. Consider wind direction, stay upwind, if possible. Evaluate the direction of product travel.
Cold vapor cloud may be white, but color will dissipate as cloud disperses - fire and explosion hazard is
still present!
Stop the source of the release, if safe to do so. Consider the use of water spray to disperse vapors.
Isolate the area until gas has dispersed. Ventilate and gas test area before entering.
7. HANDLING and STORAGE (rev. Aug-98)
HANDLING and STORAGE PRECAUTIONS
Keep away from flame, sparks and excessive temperatures. Store only in approved containers. Bond
and ground containers. Use only in well ventilated areas. See also applicable OSHA regulations for the
handling and storage of this product, including, but not limited to, 29 CFR 1910.110 Storage and Handling
of Liquefied Petroleum Gases.
8. EXPOSURE CONTROLS and PERSONAL PROTECTION (rev. Aug-94)
ENGINEERING CONTROLS
Use adequate ventilation to keep gas concentrations of this product below occupational exposure and
flammability limits, particularly in confined spaces. Use explosion-proof equipment and lighting in
classified/controlled areas.
EYE/FACE PROTECTION
Splash-proof safety goggles and/or faceshield for protection from pressurized gas
SKIN PROTECTION
Wear apron, faceshield, and cold-impervious, insulating gloves may protect from pressurized gas.
RESPIRATORY PROTECTION
Use a NIOSH/MSHA approved positive-pressure, supplied air respirator with escape bottle or self-
contained breathing apparatus (SCBA) for gas concentrations above occupational exposure limits, for
potential for uncontrolled release, if exposure levels are not known, or in an oxygen-deficient atmosphere.
CAUTION: Flammability limits (i.e., explosion hazard) should be considered when assessing the need to
expose personnel to concentrations requiring respiratory protection.
Refer to OSHA 29 CFR 1910.134, ANSI Z88.2-1992, NIOSH Respirator Decision Logic, and the
manufacturer for additional guidance on respiratory protection selection.
