### 3. COMPOSITION/INFORMATION ON INGREDIENTS

Chemical Name CAS-No Volume % Chemical Formula Propane 74-98-6 >99 C 3 H 8 

### 4. FIRST AID MEASURES Eye Contact Immediately flush with plenty of water. After initial flushing, remove any contact lenses and continue flushing for at least 15 minutes. Call a physician immediately. Skin Contact Clothing frozen to the skin should be thawed before being removed. In case of contact with liquefied gas, thaw frosted parts with lukewarm water. Inhalation PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF INHALATION OVEREXPOSURE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS. Conscious inhalation victims should be assisted to an uncontaminated area and inhale fresh air. If breathing is difficult, administer oxygen. Unconscious persons should be moved to an uncontaminated area and, as necessary, given artificial resuscitation and supplemental oxygen. Treatment should be symptomatic and supportive. Ingestion None under normal use. Get medical attention if symptoms occur. Notes to Physician Keep victim warm and quiet.



### 5. FIRE-FIGHTING MEASURES Flammable Properties Extremely flammable. Containers may explode when heated. Skin Absorption Hazard No known hazard in contact with skin. Ingestion Not an expected route of exposure. Eyes None known. Contact with rapidly expanding gas near the point of release may cause frostbite. Inhalation

Skin None known. Contact with rapidly expanding gas near the point of release may cause frostbite. May cause central nervous system depression with nausea, headache, dizziness, vomiting, and incoordination. High concentrations may also cause cardiac sensitization resulting in irregular heartbeat and may make the individual more susceptible to cardiac effects of substances such as epinephrine and adrenaline.PROPANE , Material Safety Data Sheet , Revision Date 27-Sep-2013 , Page 3 / 9

___________________________________________________________________ Suitable Extinguishing Media Dry chemical or CO 2 . Water spray or fog. DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED. Hazardous Combustion Products Carbon monoxide. Carbon dioxide (CO 2 ). Explosion Data Sensitivity to Mechanical Impact None Sensitivity to Static Discharge Yes. Specific Hazards Arising from the Chemical 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. Ruptured cylinders may rocket. Protective Equipment and Precautions for Firefighters If possible, stop the flow of gas. Do not extinguish the fire until supply is shut off as otherwise an explosive-ignition may occur. If the fire is extinguished and the flow of gas continues, use increased ventilation to prevent build-up of explosive atmosphere. Ventilation fans must be explosion proof. Use non-sparking tools to close container valves. Isolate spill or leak area for at least 100 meters (330 feet) in all directions. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Vapors may travel to source of ignition and flash back. Use water spray to cool surrounding containers. Be cautious of a Boiling Liquid Evaporating Vapor Explosion, BLEVE, if flame is impinging on surrounding containers. As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear.



### 6. ACCIDENTAL RELEASE MEASURES Personal Precautions ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). 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. Environmental Precautions Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas. Methods for Containment Stop the flow of gas or remove cylinder to outdoor location if this can be done without risk. If leak is in container or container valve, contact the appropriate emergency telephone number in Section 1 or call your closest Linde location. Methods for Cleaning Up Do not direct water at spill or source of leak. Return cylinder to Linde or an authorized distributor.



### 7. HANDLING AND STORAGE Handling Ground and bond all lines and equipment associated with product system. All equipment should be non-sparking and explosion proof. Remove all sources of ignition. Ensure adequate ventilation. "NO SMOKING" signs should be posted in storage and use areas. Never attempt to lift a cylinder by its valve protection cap. Protect cylinders from physical damage; do not drag, roll, slide or drop. When moving cylinders, even for short distance, use a cart designed to transport cylinders. Use equipment rated for cylinder pressure. Use backflow preventive device in piping.PROPANE , Material Safety Data Sheet , Revision Date 27-Sep-2013 , Page 4 / 9

___________________________________________________________________ Use an adjustable strap wrench to remove over-tight or rusted caps. Never insert an object (e.g. wrench, screwdriver, pry bar,etc.) into valve cap openings. Doing so may damage valve, causing leak to occur. If user experiences any difficulty operating cylinder valve discontinue use and contact supplier. Never put cylinders into trunks of cars or unventilated areas of passenger vehicles. Never attempt to refill a compressed gas cylinder without the owner's written consent. Never strike an arc on a compressed gas cylinder or make a cylinder a part of an electrical circuit. For additional recommendations consult Compressed Gas Association's (CGA) Safety Bulletin SB-2, Oxygen-Deficient Atmospheres. Storage Outside or detached storage is preferred. Protect from physical damage. Cylinders should be stored upright with valve protection cap in place and firmly secured to prevent falling. Store in cool, dry, well-ventilated area of non-combustible construction away from heavily trafficked areas and e m e r g e n c y e x i t s
. K e e p a t t e m p e r a t u r e s b e l o w 5 2 ° C / 1 2 5 ° F

. F u l l a n d e m p t y c y l i n d e r s s h o u l d b e segregrated. Use a "first in-first out" inventory system to prevent full cylinders from being stored for excessive periods of time. Always store and handle compressed gas cylinders in accordance with Compressed Gas Association, pamphlet CGA-P1, Safe Handling of Compressed Gases in Containers.


### 8. EXPOSURE CONTROLS / PERSONAL PROTECTION Exposure Guidelines

Other Exposure Guidelines Vacated limits revoked by the Court of Appeals decision in AFL-CIO v. OSHA, 965 F.2d 962 (11th Cir., 1992). Engineering Measures Explosion proof ventilation systems. Showers. Eyewash stations. Ventilation Use ventilation adequate to keep exposures below recommended exposure limits. Personal Protective Equipment Eye/Face Protection Wear protective eyewear (safety glasses). Skin and Body Protection W o r k g l o v e s a n d s a f e t y s h o e s a r e r e c o m m e n d e d w h e n h a n d l i n g c y l i n d e r s
. C o t t o n o r N o m e x ® clothing is recommended to prevent static build-up. Respiratory Protection General Use If exposure limits are exceeded or irritation is experienced, NIOSH/MSHA approved respiratory protection should be worn. Positive-pressure supplied air respirators may be required for high airborne contaminant concentrations. Respiratory protection must be provided in accordance with current local regulations. Emergency Use Use positive pressure airline respirator with escape cylinder or self contained breathing apparatus for oxygen-deficient atmospheres (<19.5%). Hygiene Measures Wear suitable gloves and eye/face protection.PROPANE , Material Safety Data Sheet , Revision Date 27-Sep-2013 , Page 5 / 9
