NGL Mix usually consists of a mixture of propane and butane isomers and the composition may be variable. The
product is deemed to be a complex mixture, as defined under Section 2 of the Controlled Products Regulations
thus the ingredients of the mixture need not be identified as permitted in Section 5 of the regulations.

4. HEALTH HAZARD INFORMATION:
NATURE OF HAZARD
Inhalation: NGL Mix is a simple asphyxiant and displaces oxygen from the breathing atmosphere. Oxygen
content of the atmosphere must not be allowed to fall below 19.5%. Lack of oxygen may cause dizziness,
headaches, nausea, vomiting, disturbed respiration, diminished awareness, faulty judgment, increasing fatigue,
impaired muscular coordination, convulsions, and death.
Eye Contact: Contact with gas or liquefied gas may cause burns and frostbite to the eyes.
Skin Contact: Contact with gas or liquefied gas may cause burns and frostbite to the skin.
Ingestion: Ingestion is not an applicable route of exposure for gases.
TOXICOLOGICAL SUMMARY:
ACUTE TOXICITY DATA:
ROUTES OF ENTRY: Inhalation and skin
TOXICITY TO ANIMALS: Butane: LC50: 202000 ppm/4h (mouse).
ACUTE EFFECTS ON HUMANS:
EYES: Contact with gas or liquefied gas may cause burns and frostbite.
SKIN: Contact with gas or liquefied gas may cause burns and frostbite.
INHALATION: Headaches, loss of appetite, drowsiness. Asphyxiation due to the displacement of oxygen.
INGESTION: Not applicable.
OTHER TOXICITY DATA: Aliphatic hydrocarbon gases (C2 to C4) have been associated with CNS depression
and possible cardiac sensitization.
CARCINOGENICITY: None Known.
EFFECTS OF CHRONIC EXPOSURE TO THE PRODUCT: N-butane has been associated with possible cardiac
arrhythmias. Aliphatic hydrocarbon gases (C2 to C4) have been associated with CNS depression and possible
cardiac sensitization.
Sludge and tank scale from LPG storage tanks, bulk delivery truck tanks, railway tank cars, fuel filters and
strainer screens may contain trace amounts of Naturally Occurring Radioactive Materials (NORM's).
Equipment used for the transfer of LPG such as piping and hoses, pumps and compressors may have detectable
levels of NORMS on inner surfaces.
Workers involved in cleaning, repair or maintenance on inner surfaces of such equipment should avoid breathing
dust generated from such activities. Suitable safe operating practices should be developed for these activities,
detailing appropriate occupational hygiene and disposal practices.
IRRITANCY: None known
SENSITIZATION: Cardiac sensitization has not been demonstrated in humans.
REPRODUCTIVE TOXICITY: None known
TERATOGENICITY: None known
MUTAGENICITY: None known.
TOXICOLOGICALLY SYNERGISTIC PRODUCTS: None known.
5. FIRE HAZARD:
Flash Pt(癈): -135癈 (ethane)
Auto-ignition Temp (癈): 472癈.
Flammable Limits (% volume): LEL: 3.0 % (ethane) UEL 12.5 % (ethane)
General Hazards: Extremely flammable gas. Will ignite easily in the presence of any source of ignition over a
wide range of concentrations and even at very low temperatures. Containers may explode when heated. Ruptured
cylinders may rocket.
Means of extinction: CAUTION: This product has a low flash point, use of water spray when fighting fire may be
inefficient. SMALL FIRE: Use DRY chemicals, CO2, water spray or foam. LARGE FIRE: Use water spray, fog or
foam. DO NOT use water jet. If tank, rail car or tank truck is involved in a fire, Evacuate for 1600 meters (1 mile)
in all directions due to the potential of a BLEVE, and contact local emergency personnel.
DO NOT extinguish a leaking gas flame unless leak can be stopped. Shut off fuel to fire if it is possible to do so
without being exposed to a hazard. If this is impossible, withdraw from area and let fire burn out under controlled
conditions. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tank
due to fire. Cool containing vessels with water spray in order to prevent pressure build-up, auto ignition or
explosion.
Self-contained breathing apparatus (SCBA) will be required if approaching a NGL fire, or to enter enclosed areas
or buildings where NGL vapours, in unknown concentrations, may be present.
Leak Response: Evacuate immediate area. Trained personnel using pre-planned procedures should respond to
uncontrolled releases. Proper protective equipment should be used. In case of a gas release, clear the affected area,
protect people, and respond with trained personnel.
Eliminate all ignition sources and provide maximum explosion proof ventilation. If the gas is leaking from a cylinder
or valve, contact the supplier. Adequate fire protection must be provided. Use only non-sparking tools and
equipment during the response.
Use only non-sparking tools and equipment. Locate and seal the source of the leaking gas. Allow the gas to
dissipate. Combustible gas concentrations must be below IDLH prior to entry. Monitor the surrounding area for
combustible gas levels and oxygen level. The atmosphere must have at least 19.5% oxygen before personnel can
be allowed in the area without SCBA.
Where possible attempt to close the main source valve prior to entering the area. If this does not stop the release (or
if it is not possible to reach the valve) allow the gas to release in-place or remove the container to a safe area and
allow the gas to be released there.
THIS IS AN EXTREMELY FLAMMABLE GAS. Protection of all personnel and the area must be maintained.
Handle damaged cylinders with extreme care. Dispose of according to applicable federal, provincial and local
regulations.
6. PHYSICAL DATA:

7. PREVENTATIVE MEASURES:
Respiratory Protection: Use product in a well-ventilated area, away from all sources of ignition, including
smoking. If ventilation is inadequate when handling the product, use SABA or SCBA to minimize risk of oxygen
asphyxiation.
Skin Protection: Wear long sleeved shirt or jacket, long legged pants that are not tucked into boots or shoes,
and insulated gloves suitable for low temperatures when handling liquid product.
Eye Protection: Wear chemical goggles and a face shield when handling liquid product.
Exposure Control: Enclose process to the greatest degree possible. Ventilate area (mechanical general and/or
local exhaust ventilation) where product is used, stored and/or handled to maintain airborne concentration well
below the applicable exposure limit. It is desirable to maintain the airborne concentration at half the applicable
exposure limit (the action level) or less.
Ventilation system should be a non-sparking type and should be vented directly to the outdoors. It should also be
grounded and be separate from other exhaust ventilation systems. Adequate make-up air must be provided.
Waste Disposal: Set up barricades to prevent spread of liquid. Eliminate all sources of ignition. Prevent liquid
from entering drains and sewers. Allow small amounts of liquid to evaporate with adequate ventilation. Dispose
according to applicable federal, provincial and local regulations.
Handling/Storage: Use in a well-ventilated area, away from all sources of ignition, including smoking. Ground
and bond all lines and equipment. Use a non-sparking ventilation system, explosion-proof equipment, and
intrinsically safe electrical equipment.
Do not lift cylinders by their caps or handle them with oily hands. Secure cylinders in place, in an upright position
at all times. Leave valve cap on until cylinders are secured in place and ready for use. Do not drop cylinders or
allow them to strike each other. Close all valves when not in use. Ground all drums and transfer vessels.
Store in a cool, dry well-ventilated area out of sunlight and away from any sources of ignition. Do not store at or
above 49C (120F). Do not store in areas containing flammable or combustible products, oxidizers, or materials
that support combustion.
