Petroleum gas (liquefied)
Agent Name
Petroleum gas (liquefied)
Synonyms
Bottled gas; Compressed petroleum gas; Liquefied hydrocarbon gas; Liquefied petroleum gas; LPG; [NIOSH] UN1075
Category
Petroleum, Refined
Description
Colorless, noncorrosive, odorless gas when pure; Note: A foul-smelling odorant is usually added. Shipped as a liquefied compressed gas; [NIOSH]
Sources/Uses
Used as a fuel for heating, motorized vehicles, and welding/cutting/brazing; [Hawley] "LPG is produced from natural gas and is recovered during petroleum refining." Natural gas contains primarily methane, and also ethane, propane, and butane. Natural gas occurs in marshes associated with petroleum deposits, and it is also produced by waste decomposition. [ACGIH]
Comments
TSCA Definition 2008: A mixture of crude oil distillates with carbon numbers of C3 to C7 and boiling points of -40 deg C to 80 deg C; [ChemIDplus] LPG is a fuel mixture of propane, propylene, butanes, and butylenes; Possible frostbite from contact with liquid; [NIOSH] Simple asphyxiant; "TLV basis" for aliphatic hydrocarbon gases are CNS impairment and cardiac sensitization; [ACGIH]
Skin Designation (ACGIH)
No
Excerpts from Documentation for IDLHs
Basis for revised IDLH: Because L.P.G. may cause asphyxia [Proctor et al. 1988] at concentrations well above the lower explosive limit (LEL), the revised IDLH for L.P.G. is 2,000 ppm based strictly on safety considerations (i.e., being about 10% of the LELs of 1.9% for butane and 2.1% for propane).
Explanatory Notes
IDLH = 10% LEL (lower explosive limit); A simple asphyxiant {See Appendix F.) and explosion hazard; [TLVs and BEIs]
Neurotoxin
Acute solvent syndrome
Other Poison
Simple Asphyxiant
