4. Fire and Explosion Hazard Data
o
Flammability Classification: Flammable Flash Point (F): -162 F LEL (%): 2
o
Ignition Temperature: 927 F Method: TCC UEL (%): 11.1
Extinguishing Media:
Water; Carbon dioxide; Dry chemical.
Fire Fighting Procedures:
If possible, stop the flow of gas with a remote valve. Use water spray to cool containers exposed to fire. If fire is extinguished and
flow of gas is continued, increase ventilation to prevent a build up of flammable or explosive atmosphere. Extinguish all sources of
ignition.
Be cautious of a Boiling Liquid Evaporating Vapor Explosion (BLEVE) if flame is impinging on surrounding containers. Direct 500-
gpm water stream onto containers above the liquid level with remote monitors. Limit the number of personnel in proximity to the
fire. Evacuate surrounding areas to at least 3000 feet in all directions.
Fire & Explosion Hazard:
This product will ignite at ambient temperatures and can be expected to form a flammable mixture upon release to atmosphere.
May burn with an almost invisible flame in bright light.

6. Health Hazard Data
Route(s) of Entry: Eye contact Skin Contact Skin Absorption
Yes Yes No
Inhalation Ingestion
Yes No
Health Hazards:
Acute Propylene is relatively nontoxic. Simple hydrocarbons can irritate the eyes, mucous membranes and
respiratory system at high concentrations.
Inhalation of high concentrations may cause dizziness, disorientation, decreased coordination,
narcosis, nausea, or narcotic effects.
Propylene may displace oxygen if released in a confined space. Maintain oxygen levels above
19.5% to prevent asphyxiation.
Product is a simple asphyxiant. Effects of oxygen deficiency may include any, all or none of the
following: rapid breathing, diminished mental alertness, impaired muscle coordination, blurred
speech, and fatigue. As asphyxiation progresses; nausea, vomiting, and loss of consciousness may
occur, eventually leading to convulsions, coma and death.
Chronic N/A
Carcinogenicity: NTP IARC Monographs OSHA
No No No
Signs and Symptoms of Exposure and Emergency First Aid Procedures:
Eye Contact None anticipated. Simple hydrocarbons can irritate the eyes.
If pain is present, seek attention of an ophthalmologist for further treatment.
Skin Contact None anticipated as product is a gas at room temperature.
Remove contaminated clothing and flush area with cold water. Seek medical attention if irritation
persists.
Signs and Symptoms of Exposure and Emergency First Aid Procedures:
Inhalation Simple hydrocarbons can irritate the mucous membranes and respiratory system at high
concentrations. Inhalation of high concentrations may cause dizziness, disorientation, decreased
coordination, narcosis, nausea, or narcotic effects. Propylene may displace oxygen if released in a
confined space. Maintain oxygen levels above 19.5% to prevent asphyxiation.
Product is a simple asphyxiant. Effects of oxygen deficiency may include any, all or none of the
following: rapid breathing, diminished mental alertness, impaired muscle coordination, blurred
speech, and fatigue. As asphyxiation progresses; nausea, vomiting, and loss of consciousness may
occur, eventually leading to convulsions, coma and death.
Conscious victim should be assisted to an uncontaminated area and allowed to inhale fresh air.
Unconscious victim should be moved to an uncontaminated area and given assisted respiration and
supplemental oxygen.
Ingestion Ingestion is unlikely.
Seek medical attention.
Medical Conditions Aggravated by Exposure:
Persons of ill health that may be aggravated by exposure to propylene should not be allowed to work with this product.

7. Precautions for Safe Handling and Use
Actions if Released or Spilled:
Evacuate all personnel from affected area. Use appropriate protective equipment. Increase ventilation to prevent build up of
flammable or explosive atmosphere. Extinguish all sources of ignition. If leak is in user's equipment, be certain to purge piping with
inert gas prior to attempting repairs. If leak is in container or container valve, contact the nearest distributor.
Waste Disposal Method:
Do not attempt to dispose of waste or unused quantities. Return in properly labeled shipping container, with any valve outlet plugs or
caps secured and valve protection caps in place.
Handling and Storage Precautions:
Use only in well-ventilated areas. Valve protection caps must remain in place unless cylinder is secured with valve outlet piped to
point of use. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a pressure-reducing
regulator when connecting cylinder to lower pressure piping or systems. Do not heat cylinder. Use a check valve or trap in the
discharge line to prevent hazardous backflow into the cylinder.
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavy traffic areas and emergency exits.
o
Do not allow temperature of cylinder storage area to exceed 125 F. Cylinders should be stored upright and firmly secured to
prevent falling or being knocked over. Full and empty cylinders should be segregated.
Do not attempt to repair or alter cylinders. Do not tamper with the valve or pressure relief devices. If the valve begins to leak, move
the cylinder to an open area and contact the nearest distributor. A leaking cylinder should be properly marked to prevent further use.
Do not store propylene within 20 feet of oxygen or combustible materials unless separated by a one-half hour rated, 5 feet high
firewall. Post "NO SMOKING OR OPEN FLAMES" signs in the storage and use area.
Other Precautions:
Compressed gas cylinders should only be refilled by qualified personnel. Shipment of compressed gas cylinders that have been
filled without the consent of the cylinder owner is a violation of federal law (49 CFR).
Always secure cylinders in an upright position during transportation. Never transport cylinders in enclosed space such as a vehicle
truck or van.
For additional recommendations, see CGA Pamphlets P-1, SB-2.
