Propylene

SECTION 2: Hazards identification

EMERGENCY OVERVIEW Propylene is a flammable, colorless liquefied compressed gas packaged in cylinders under its own vapor pressure of 152.2 psia at 70 °F. It poses an immediate fire and explosion hazard when mixed with air at concentrations exceeding 1.9%. High concentrations that can cause rapid suffocation are above the lower flammable limit and must not be entered. Propylene is heavier then air and may collect in low areas or travel along the ground where there may be an ignition source present. It is generally odorless at concentrations below 2.0%. Direct contact with liquid can cause frostbite. EMERGENCY TELEPHONE NUMBERS (800) 523-9374 Continental U.S., Canada and Puerto Rico (610) 481-7711 Other locations

Principle Routes of Exposure

EYE CONTACT: Contact with liquid (or rapidly expanding gas) may cause irritation and frostbite. INGESTION: Ingestion is not a for Propylene INHALATION: Propylene is a Central Nervous System (CNS) depressant and a mild anesthetic. It can also displace the amount of oxygen in the air necessary to support life. Exposure to oxygen- deficient atmospheres (less than 19.5%) may produce dizziness, nausea, vomiting, loss of MSDS # 1083 Propylene Page 1 of 5 consciousness, and death. At very low oxygen concentrations (less than 12%) unconsciousness and death may rapidly occur without warning. It should be noted that before suffocation could occur, the lower flammable limit for Propylene in air will be exceeded; causing both an oxygen deficient and an explosive atmosphere. SKIN CONTACT: Contact with liquid (or rapidly expanding gas) can cause irritation and frostbite. Skin contact SYMPTOMS: Repeated or prolonged contact may cause dermatitis. TARGET ORGANS: Skin
