68476-85-7 |
Major Category |
Toxic Gases & Vapors |
Synonyms |
Bottled gas; Compressed petroleum gas; Liquefied hydrocarbon gas; Liquefied petroleum gas; LPG; [NIOSH] UN1075 |
Category |
Simple Asphyxiants |
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] |
Comments |
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] |
Exposure Assessment |
Skin Designation (ACGIH) |
No |
TLV (ACGIH) |
1000 ppm |
PEL (OSHA) |
1000 ppm |
IDLH (NIOSH) |
2000 ppm |
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); For TLV, see aliphatic hydrocarbon gases: alkane (C1-C4); [ACGIH] |
Flammability (NFPA) |
4: burns readily |
Adverse Effects |
Neurotoxin |
CNS Solvent Syndrome |
Other Poison |
