Plains Marketing Canada Natural Gas, Sweet MSDS
EYES
This product is a moderate eye irritant. Direct contact with rapidly escaping gas may cause cryogenic (freezer) burns
or frostbite. Vapours may cause irritation to the eyes. Conjunctiva and mucous membranes resulting in redness and
tearing.
SKIN
This product is a slight skin irritant. Direct contact with rapidly escaping gas may cause cryogenic (freezer) burns or
frostbit. The appearance of injury may be delayed for a few hours, but may cause tissue to become swollen,
discolored and extremely painful; permanent damage or death may result with adequate medical treatment.
INGESTION
Natural gas is extremely unlikely to be swallowed and much more likely to be inhaled since it is in the form of a gas.
INHALATION
Vapors may cause nose and throat irritation, anesthetic effects and central nervous system (CNS) depression.
Inhalation may result in nausea, dizziness, drowsiness, headaches, loss of appetite, vomiting, loss of consciousness
and even death. Certain ingredients may produce systemic effects to the blood, liver, kidneys, central nervous system
and cardiovascular system. Inhalation of high concentrations can cause rapid CNS depression, cardiac arrhythmia,
unconsciousness, coma, and possibly death resulting from respiratory failure.
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 EFFECTS/CARCINOGENICITY
Hematologic, heptotoxic, renal, neuropyschiatric, neurologic, and carcinogenic effects. Anoxia, polyneuropathy
characterized by muscle weakness, loss of sensation, and impaired gait.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
Irritation from skin exposure may aggravate existing open wounds, skin disorders, and dermatitis (rash) conditions.
Chronic respiratory disease, liver or kidney dysfunction, or pre-existing central nervous system disorders may be
aggravated by exposure.
4. FIRST AID MEASURES
EYES
In case of contact with eyes, immediately flush with clean, low-pressure water for at least 20 minutes. Hold eyelids
open to ensure adequate flushing. Seek medical attention immediately.
SKIN
This material can cause drying and redness of the skin. High-pressure releases may inject gas under the skin and
requires immediate medical attention.
INGESTION
Rinse mouth with water. DO NOT induce vomiting. If conscious, give 1-2 glasses of milk or water to drink. Never
administer liquids to an unconscious person. If spontaneous vomiting occurs lean victim forward to reduce the risk
of aspiration into the lungs. Seek medical attention immediately and monitor for breathing difficulty.
INHALATION
Ensure your own safety and use the appropriate respiratory protection to immediately remove the victim to an
uncontaminated area. Give CPR or artificial respiration as needed and give oxygen if breathing is difficult. Keep
victim at rest and get medical attention.

5. FIRE FIGHTING MEASURES
FLAMMABLE PROPERTIES
-156oC (-249 oF) (Tagliabue CC) Flammable Gas
FLASH POINT:
537oC (1000 oF)
AUTO IGNITION:
LOWER EXPLOSIVE LIMIT: 5%
UPPER EXPLOSIVE LIMIT: 15%
FIRE AND EXPLOSION HAZARDS
This product is EXTEMELY FLAMMABLE. DO NOT ATTEMPT TO ENTINGUISH A LEAKING GAS
UNLESS THE LEAK CAN BE STOPPED. Vapours will ignite easily in the presence of any source of ignition over
a wide range on concentrations and even at very low temperatures. Containers may explode when heated. Ruptured
cylinders may rocket.
EXTINGUISHING MEDIA
SMALL FIRES: Dry chemical or CO2.
LARGE FIRES: Water spray or fog.
FIRE FIGHTING INSTRUCTIONS
Small fires in the incipient (beginning) stage may typically be extinguished using handheld portable fire
extinguishers and other fire fighting equipment.
Fire fighting activities that may result in potential exposure to high heat, smoke or toxic byproducts of combustion
should require approved self-contained breathing apparatus (SCBA) with full-facepiece and full protective
firefighting clothing.
Isolate area around container involved in fire. Cool tanks, shells, and containers exposed to fire and excessive heat
with water. If leak or spill has not ignited, ventilate area and determine if water spray would assist in dispersing gas
or vapor to protect personnel attempting to stop leak. Water may be useful in flushing spills away from ignition
sources; however, do NOT flush petroleum products down public sewers or other drainage systems.
For massive fires the use of unmanned hose holders or monitor nozzles may be advantageous to further minimize
personnel exposure. Major fires may require withdrawal, allowing the tank to burn. Large storage tank fires
typically require specially trained personnel and equipment to extinguish the fire, often including the need for
properly applied fire fighting foam. Refer to NAERG Guide 115.
6. ACCIDENTAL RELEASE MEASURES
ACTIVATE YOUR FACILITY'S SITE SPECIFIC EMERGENCY RESPONSE PLAN if available.
Evacuate nonessential personnel and remove or secure all ignition sources for 800m (1/2 mile). Consider wind
direction; stay upwind and uphill, if possible. Evaluate the direction of product travel, diking, sewers, etc. to
confirm spill areas.
Carefully contain and stop the source of the spill, if safe to do so. Do not flush down sewer or drainage systems.
Protect bodies of water by diking, if possible. The use of fire fighting foam may be useful in certain situations to
reduce vapors.
SMALL SPILLS: Take up with sand or other oil absorbing materials. Carefully shovel, scoop or sweep up into a
waste container for reclamation or disposal. Cleanup crews must be properly trained and must utilize proper
protective equipment.
LARGE SPILLS: Ensure your own safety and use the appropriate respiratory protection. An approved self-contained
breathing apparatus (SCBA) with full-face piece may be required. Isolate spill or leak area immediately for at least
Issue date: June 30, 2008 Page 3 of 7
Plains Marketing Canada Natural Gas, Sweet MSDS
50 to 100 metres (160 to 330 feet) in all directions. Keep unauthorized personnel away and stay upwind. Many gases
are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks,
etc.). keep out of low areas. The proper use of water spray may effectively disperse product vapours, preventing
contact with ignition sources or areas / equipment that require protection. Consider initial downwind evacuation for
at least 800m (1/2 mile). Refer to NAERG Guide 115.
7. HANDLING AND STORAGE
HANDLING PRECAUTIONS
Ensure your own safety and use the appropriate respiratory protection. An approved self-contained breathing
apparatus (SCBA) with full-face piece may be required. Handle as a flammable gas. Keep away from all sources of
heat, spraks, open flame or any sources of ignition as well as flammable materials or oxidizers. Do not pressurize,
cut, heat, weld or expose such containers to sources of ignition. Use only with adequate ventilation and avoid
breathing vapours. Ground and bond all lines and equipment. Use intrinsically safe electrical equipment.
STORAGE PRECAUTIONS
Outside storage is recommended. Store in a cool, dry and well ventilated area out of sunlight and away from all
sources of ignition. Avoid storage in low, confined locations or near incompatible materials such as other flammable
materials, oxidizers or materials that support combustion. This storage area should comply with NFPA 30
("Flammable and Combustible Liquid Code"). The cleaning of tanks previously containing this product should
follow API Recommended Practice (RP) 2013 "Cleaning Mobile Tanks In Flammable and Combustible Liquid
Service: and API RP 2015 "Cleaning Petroleum Storage Tanks".
WORK/HYGIENIC PRACTICES
Emergency eye wash capability should be available in the vicinity of any potential splash exposure. Use good
personal hygiene practices. Avoid repeated and/or prolonged skin exposure. Wash hands before eating, drinking,
smoking, or using toilet facilities. Do not eat, drink or smoke in areas of use or storage. Do not use gasoline or
solvents (naphtha, kerosene, etc) for washing this product from exposed skin areas. Waterless hand cleansers are
effective.
Promptly remove contaminated clothing and launder before reuse. Use care when laundering to prevent the
formation of flammable vapors which could ignite via washer or dryer. Consider the need to discard contaminated
leather shoes and gloves.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Issue date: June 30, 2008 Page 4 of 7
Plains Marketing Canada Natural Gas, Sweet MSDS
with organic vapor cartridges or canister may be permissible under certain circumstances where airborne
concentrations are or may be expected to exceed exposure limits or for odor or irritation. Protection provided by air-
purifying respirators is limited and should not be considered especially when odor cannot be used to determine
respirator effectiveness. Use a positive pressure, air-supplied respirator if there is a potential for uncontrolled
release, exposure levels are not known, or any other circumstance where an air-purifying respirator may not provide
adequate protection.
Refer to CSA Standard "Selection, Use and Care of Respirators" (Z94.4-02) and NIOSH Respirator Decision Logic
