                                               EMERGENCY OVERVIEW

                                                       DANGER!!

 EXTREMELY FLAMMABLE Will be easily ignited by heat, sparks or flames. Will form explosive mixtures

 with air. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to

 source of ignition and flash back. Vapors may cause dizziness or asphyxiation without warning. Some may be

 irritating if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, severe injury

 and/or frostbite. Fire may produce irritating and/or toxic gases.









ROUTE(S) OF ENTRY

Eyes: Yes                 Skin:    Yes



EYES

MODERATE TO SEVERE IRRITANT. Contact with liquid will cause cryogenic (freezer) burns or frostbite.

Vapors may cause irritation to the eyes, conjunctiva, and mucous membranes, causing redness and tearing.



SKIN

SLIGHT TO MODERATE IRRITANT. Direct contact with the liquefied product causes burns & frostbite.

Inhalation, skin and eye contact by liquid. Contact with liquid will cause cryogenic (freezer) burns or frostbite.

High pressure skin injections are serious medical emergencies. 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 without adequate medical treatment.



INGESTION

Propane is extremely unlikely to be swallowed and much more likely to be inhaled. If propane is swallowed severe

burns will occur wherever propane contacts any tissues.

INHALATION

Vapors may cause nose and throat irritation, anesthetic effects and central nervous system (CNS) depression.

Inhalation may result in dizziness, drowsiness, headaches. An increased pulse rate may occur. Hyperventilation

may develop. headache, dizziness, mood disturbances, numbness of the extremities, sleepiness, mental confusion,

poor judgment and coordination, and memory loss may occur.



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

n-Butane has been reported to cause some symptoms in the central nervous system. Not known to contain

carcinogens. .



MEDICAL CONDITIONS AGGRA VA TED 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.





EYES

In case of contact with eyes, immediately flush with clean, low-pressure water for at least IS min. Hold eyelids open

to ensure adequate flushing. Seek medical attention.



SKIN

This material will cause cryogenic (freezer) burns if clothing is frozen treat by immersing in lukewarm water for 30

minutes. Remove clothing unless stuck to a burn area in which case cut around the bum leaving cloth fixed to the

bum. Obtain medical attention immediately.



INGESTION

This product is unlikely to be ingested and more likely to be inhaled. DO NOT INDUCE VOMITING BECAUSE

OF DANGER OF BREATHING LIQUID INTO LUNGS. Seek immediate medical attention. Rinse mouth with

water. Administer I to 2 glasses of water or milk to drink. Never administer liquids to an unconscious person.



If spontaneous vomiting occurs, lean victim forward to reduce the risk of aspiration. Seek medical attention.

Monitor for breathing difficulty.



INHALATION

Remove person to fresh air. If person is not breathing, ensure an open airway and administer CPR. If necessary,

provide additional air or oxygen once breathing is restored if trained to do so. Seek medical attention immediately.

FIRE AND EXPLOSION HAZARDS

EXTREMELY FLAMMABLE .. DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE

STOPPED. Move containers from fire area if you can do it without risk. Containers may explode. Will be easily

ignited by heat, sparks or flames .. Will form explosive mixtures with air .. Vapors from depressurization of

compressed liquefied gas will cause frostbite or cryogenic burns. Vapours from liquefied gas are initially heavier

than air and spread along ground .. Vapors may travel to source of ignition and flash back .. Vapours may be ignited

rapidly when exposed to heat, spark, open flame or other source of ignition. Container may explode in heat or fire.

Runoff to sewer may cause fire or explosion hazard. Review NAERG Guide 115.



EXTINGUISHING MEDIA

May 1,2008

LARGE FIRES: Water spray or fog. Water may be ineffective for fighting the fire, but may be used to cool fire-

exposed containers. Consider initial downwind evacuation for at least 800 meters (1/2 mile). Fight fire from

maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of

water until well after fire is out. Do not direct water at source of leak or safety devices; icing may occur. Withdraw

immediately in case of rising sound from venting safety devices or discoloration of tank. AL WAYS stay away from

tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; ifthis is impossible,

withdraw from area and let fire burn.



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.









ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Evacuate nonessential

personnel. Consider wind direction; stay upwind and uphill, if possible. Evaluate the direction of product travel,

diking, sewers, etc. to confirm spill areas. see Section 8 for personal protection. All equipment used when handling

the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk.

Ifpossible, turn leaking containers so that gas escapes rather than liquid. Use water spray to reduce vapors or divert

vapor cloud drift. Avoid allowing water runoff to contact spilled material. Do not direct water at spill or source of

leak. Prevent spreading of vapors through sewers, ventilation systems and confined areas. Isolate area until gas has

dispersed. CAUTION: When in contact with refrigerated/cryogenic liquids, many materials become brittle and are

likely to break without warning.









LARGE SPILLS: CALL Emergency Response Telephone Number. Isolate spill or leak area immediately for at least

50 to 100 meters (160 to 330 feet) in all directions. Keep unauthorized personnel away. Stay upwind. Many gases

are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks).

Keep out of low areas. The proper use of water spray may effectively disperse product vapors, preventing contact

with ignition sources or areas /equipment that require protection. Do not discharge solid water stream pattern into

the liquid resulting in splashing. Do not flush down sewer or drainage systems. Protect bodies of water by diking, if

possible. Evacuation: Fire: If tank, rail car or tank truck is involved in a fire, ISOLATE for 1600 meters (1 mile) in

all directions; also, consider initial evacuation for 1600 meters (1 mile) in all directions.



Caution: the application of water and/or fire fighting foam may cause the spilled liquid to liberate increased amounts

of vapors, particularly when the water/foam temperature is warmer than the liquid. However, this effect may be

desirable under certain conditions to evaporate a spill quickly.



Consideration should be given to environmental clean-up and waste material generation when determining ifthe use

of large volumes of water is appropriate for non-fire emergency situations. Clean-up crews must be properly trained

and must utilize proper protective equipment.

HANDLING PRECAUTIONS

Handle as a flammable gas. Keep away from heat, sparks, and open flame. No smoking or open flame in storage,

use of handling areas. Keep containers closed and clearly labeled. Ground all containers and transfer vessels when

handling. Empty product containers or vessels may contain explosive vapors. Do not pressurize, cut, heat, weld or

expose such containers to sources of ignition. Use only with adequate ventilation. Avoid breathing vapors. Do not

use as a cleaning agent. Wash thoroughly after handling. Electrical equipment should be approved for classified

area. Emergency eye wash capability should be available in the vicinity of any potential splash exposure.



STORAGE PRECAUTIONS

Store in a well ventilated area. This storage area should comply with NFP A 30 ("Flammable and Combustible

Liquid Code"). Avoid storage near incompatible materials.



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".



NATURALLY OCCURRING RADIOACTIVE MATERIAL (NORM):

Industry experience indicates that propane contains small amounts of a radioactive gas called radon; radon decays

into other radioactive products (called radon daughters). These naturally occurring radioactive materials (called

NORM) can accumulate in production and process equipment handling propane liquids. Scales, deposits, and

sludges from this equipment may have a significant accumulation of NORM. Gamma radiation above background

may be detected external to equipment contaminated with NORM; such equipment should be assumed to be

internally contaminated with long half-life decay products that emit alpha radiation, which is a radiation hazard if

inhaled. Steps should be taken to minimize skin and inhalation exposure to NORM dusts/mists by wearing personal

protective clothing [such as disposable Tyvek (®DuPont)], utilizing respiratory protection (minimum ofHEPA

filter), and practicing good personal hygiene. Please refer to API Bulletin E2, "Bulletin on Management of Naturally

Occurring Radioactive Materials in Oil and Gas Production", April 1, 1992 for additional information on managing

NORM.



WORKIHYGIENIC PRACTICES

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.









ENGINEERING CONTROLS

Use adequate ventilation to keep vapor and gas concentrations of this product below occupational exposure and

flammability limits, particularly in confined spaces. Use explosion-proof equipment and lighting.









EYE/FACE PROTECTION

Wear appropriate eye/face protection to prevent contact with the liquid that could result in bums or tissue damage

from frostbite.



SKIN PROTECTION

Avoid repeated or prolonged skin contact. Insulated gloves should be used to prevent the potential of frostbite or

RESPIRA TORY PROTECTION

This product is a known asphyxiant and air supplied respirators are required if there is a potential for decreased

oxygen concentrations.



If exposure assessment indicates NO reduced oxygen content: 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.



When assessing the proper type of respiratory protection, also consider the occupational exposure limits applicable

to individual ingredients.



Refer to OSHA 29 CFR 1910.134, ANSI Z88.2-1992, CSA Standard "Selection, Use and Care of Respirators"

(Z94.4-02) and NIOSH Respirator Decision Logic for additional guidance on respiratory protection.
