SECTION 4: FIRE AND EXPLOSION DATA
Flash Point: -162?F
Auto Ignition: 927?F
Lower Explosion Limit: 2.0% by volume in air
Upper Explosion Limit: 11.0% by volume in air
General Fire Hazards: Liquid releases vapors hat readily form a flammable mixture with air. Dangerous fire
and explosion hazard when exposed to heat, sparks or flame. Vapors are heavier than air and may travel
long distances to a point of ignition. Container may explode in heat or flame.
Hazardous Combusion Products: Carbon monoxide, carbon dioxide and various non-combusted hydrocarbons.
Extinguishing Media: Dry chemical, foam, carbon dioxide, Halon or water.
Unusual Fire Hazards: Use extreme caution when fighting liquefied petroleum gas fires. Heated containers
may rupture violently and suddenly without warning due to vessel overpressure (BLEVE - boiling liquid
expanding vapor explosions). If safe to do so, stop the flow of gas and allow the flame to burn out. Extinguishing
the flame before shutting off the supply can cause formation of explosive mixtures. In some cases it may be
preferred to allow the flame to continue to burn. Use water to cool equipment, surfaces and containers
exposed to fire and excessive heat.
SECTION 5: REACTIVITY DATA
Chemical Stability: Stable
Hazardous Decomposition Products: Carbon oxides and various hydrocarbons formed when burned.
Incompatibility: Strong oxidizers such as nitrates, perchlorates, chlorine and fluorine.
Hazardous Polymerization: Does not polymerize except under special conditions (extreme temperature,
pressure, oxidizers).
Conditions to Avoid: Sources of heat, sparks or flame.

SECTION 6: HAZARDS IDENTIFICATION
Overview: This product contains propylene. A colorless liquid that repidly turns into a gas at standard
atmospheric temperatures and pressure. Propylene has a slight hydrocarbon odor. In commerce propylene is
packaged as a liquified and gas under pressure. Propylene is extremely flammable and explosive. At high
concentrations it acts as a simple asphixiant by diluting and displacing oxygen, particularly in confined
spaces. Direct contact with liquefied product may cause freeze burns and frontbite. Use this product only in
well ventilated areas and, where appropriate, proper respiratory protection and personal protective equipment
should be worn.
Primary Entry Routes: Inhalation
Target Organs: Respiratory system
Potential Health Effects:
* Inhalation: Product is an anesthetic at high concentrations. Inhalation may cause central nervous system
depression producing dizziness, drowsiness, headache and similar narcotic symptoms. Extremely high
concentrations can cause asphyxiation and death by displacing oxygen from the breathing atmosphere.
* Eyes: Vapor is generally non-irritating to the skin. Contact with liquefied gas or rapidly expanding gases
may cause freeze burns and frontbite.
* Skin: Vapor is generally non-irritating to the skin. Contact with liquefied gas or rapidly expaniding gases may
cause freeze burns and frontbite.
* Ingestion: Ingestion is not likely.
Medical Conditions Aggravated by Exposure: Chronic diseases or disorders of the respiratory system.
Toxicological Information: Propylene is an anesthetic and is mildly irritating to the mucous membranes. At
high concentrations propylene acts as a simple asphixiant without significant potential for systematic toxicity.
High concentrations can cause death due to oxygen depletion. Toxicity data can be found in the Registry of
Toxic Effects of Chemical Substances available on-line from the National Institute for Occupational Safety
and Health (NIOSH).
Carcinogenic Effects: Propylene is not identified as being carcinogenic by the International Agency for
Research on Cancer (IARC), The National Toxicology Program (NTP), ACGIH or OSHA.
SECTION 7: FIRST AID MEASURES
Eye Contact: Flush eyes with plenty of water for at least 15 minutes while occasionally lifting the eyelids.
Seek medical attention.
Skin Contact: Remove contaminated clothing. Wash with soap and water. Get midical attention if irritation or
redness develops. In case of frostbite, place affected area in warm water or wrap in blankets if warm water is
not available. DO NOT USE HOT WATER. Seek immediate medical attention.
Inhalation: Remove to fresh air. Administer oxygen or artificial respiration if necessary. Seek immediate
medical attention.
Ingestion: Risk of ingestion is extremely low. Seek immediate medical attention in cases of ingestion or oral
exposure.
SECTION 8: PERSONAL PROTECTIVE EQUIPMENT
Engineering Controls: Good industrial hygiene practice requires that engineering controls be used where
feasible to reduce workplace concentrations of hazardous materials.
Ventilation: Use adequate ventilation to keep gas and vapor concentrations of this product below the
occupational exposure and flammability limits, particularly in confines spaces. Use mechanical ventilation that
is explosion proof.
Respiratory Protection: Maintain oxygen levels above 19.5% in the workplace. Respirators must be worn if
ambient concentrations of contaminants exceed prescribed exposure limits. Seek professional advice prior to
respirator selection and use. Follow OSHA respirator regulations (29 CFR 1910.134). Select respirator based
on its suitability to provide adequate worker protection for given work conditions, level of airborne contamination,
and presence of sufficient oxygen. When required, only NIOSH approved respirators should be used.
Protective Clothing: Protective clothing should be worn to prevent skin contact. Protective gloves should be
worn as required for welding or burning. Use insulated gloves where there is the possibility of liquid contact.
Eye Protection: Use safety glasses or goggles as required for welding or burning. Use splash-proof goggles
or faceshield where there is the possibility of liquid contact.

SECTION 9: HANDLING AND STORAGE
Handling Precautions: Keep away from flame, sparks and excessive temperatures. Use only in well-ventilated
areas.
Storage Requirements: Store in a cool, dry, well-ventilated area away from sources of ignition, strong oxidizers
or other incompatible materials. Post "No Smoking or Open Flame" signs in the storage and use areas.
Protect cylinders against physical damage. Do not cut, drill, grind or weld on empty cylinders since they may
contain explosive residues. Do not attempt to refill cylinders.
Spill Response Procedures: Evacuate area of all unnecessary personnel. Remove or shut off all sources of
ignition. Ventilate the area thoroughly.
Disposal: Waste disposal must be in accordance with appropriate Federal, State and local regulations.
DOT Requirements: Product is classified as a Hazardous Substance under 49 CFR 172.101.
