| 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] |

| 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] |
