HEALTH HAZARD DATA
TIME WEIGHTED AVERAGE EXPOSURE LIMIT
Propylene is defined as a simple asphyxiant (ACGIH 1997);it has an A4 (Not Classifiable as a Human
Carcinogen) carcinogen rating. OSHA 1995 PEL (Continued on Page 4)
SYMPTOMS OF EXPOSURE
Inhalation: Moderate concentrations so as to exclude an adequate supply of oxygen to the lungs causes
dizziness, drowsiness, and eventual unconsciousness.
Contact with evaporating liquid could cause frostbite or freezing of dermal tissue.
TOXICOLOGICAL PROPERTIES
Has been reported that breathing high concentrations causes an anesthetic effect; however, the major
property is the exclusion of an adequate supply of oxygen to the lungs.
Frostbite effects are a change in color of the skin to gray or white possibly followed by blistering.
Propylene is not listed in the IARC, NTP or by OSHA as a carcinogen or potential carcinogen. (Continued on
Page 4)
RECOMMENDED FIRST AID TREATMENT
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO
PROPYLENE. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING
APPARATUS AND BE COGNIZANT OF EXTREME FIRE AND EXPLOSION HAZARD.
Inhalation: Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Quick
removal from the contaminated area is most important. Unconscious persons should be moved to an
uncontaminated area, given assisted respiration and supplemental oxygen. Further treatment should be
symptomatic and supportive.
Dermal Contact or Frostbite: Remove contaminated clothing and flush affected areas with lukewarm water.
DO NOT USE HOT WATER. (Continued on Page 4)

SPECIAL FIRE FIGHTING PROCEDURES
If possible, stop flow of gas supply and allow fuel to consume itself. Use water spray to cool surrounding
containers.
UNUSUAL FIRE AND EXPLOSION HAZARDS
Propylene is heavier than air and may travel a considerable distance to a source of ignition. Should flame be
extinguished and flow of gas continue, increase ventilation to prevent flammable mixture formation in low
areas or pockets.

SPILL OR LEAK PROCEDURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user鈥檚
equipment, be certain to purge piping with an inert gas prior to attempting repairs. If leak is in container or
container valve, contact your closest supplier location or call the emergency telephone number listed herein.
WASTE DISPOSAL METHOD
Do not attempt to dispose of waste or unused quantities. Return in the shipping containe properly labeled,
with any valve outlet plugs or caps secured and valve protection cap in place to your supplier. For
emergency disposal assistance, contact your closest supplier location or call the emergency telephone
number listed herein.

SPECIAL HANDLING RECOMMENDATIONS
Use only in well-ventilated areas. Valve protection caps must remain in place unless container is secured
with valve outlet piped to use point. 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 (<200 psig)
piping or systems. Do not heat cylinder by any means to increase the discharge rate of product from the
cylinder. Use a check valve or trap in the discharge line to prevent hazardous back flow into the cylinder.
For additional handling recommendations, consult Compressed Gas Association鈥檚 Pamphlets P-1, P-14, and
Safety Bulletin SB-2.
SPECIAL STORAGE RECOMMENDATIONS
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of noncombustible
construction away from heavily trafficked areas and emergency exits. Do not allow the temperature where
cylinders are stored to exceed 125F (52C). Cylinders should be stored upright and firmly secured to prevent
falling or being knocked over. Full and empty cylinders should be segregated. Use a 鈥渇irst in - first out鈥?
inventory system to prevent full cylinders being stored for excessive periods of time. Post 鈥淣o Smoking or
Open Flames鈥? signs in the storage or use area. There should be no sources of ignition in the storage or use
area.
For additional storage recommendations, consult Compressed Gas Association鈥檚 Pamphlets P-1, P-14, and
Safety Bulletin SB-2.
SPECIAL PACKAGING RECOMMENDATIONS
Propylene is noncorrosive and may be used with any common structural material.
OTHER RECOMMENDATIONS OR PRECAUTIONS
Earth-ground and bond all lines and equipment associated with the propylene system. Electrical equipment
should be non-sparking or explosion proof. Compressed gas cylinders should not be refilled except by
qualified producers of compressed gases. Shipment of a compressed gas cylinder which has not been filled
by the owner or with his (written) consent is a violation of Federal Law (49CFR). (Continued on Page 4)
*Various Government Agencies (i.e. Department of Transportation, Occupational Safety and Health Administration, Food and Drug Administration
