General Characteristics
Propane is a mixture of liquefied hydrocarbons mostly with three carbons in the molecule, with predominant propane content. Liquid-state propane is a colourless liquid, easy to evaporate, and of specific odour.

Application
Propane is used for special purposes within machinery and chemical industries (P I and P II) or for deasphalting and selective refining of mineral oils (P III).
Packaging, Storage, Transportation
Propane is supplied under pressure in rail tankers and road tankers. Propane storage, transportation and handling must comply with respective legal regulations.
Transport Sign
RID/ADR: 2/2f
UN: 1965
Kemler: 23
Basic Safety Data
Propane is highly volatile, flammable liquid, which is stored under pressure in pressure containers. When released into the environment with atmospheric pressure, vaporization by boiling at temperatures down to – 40 °C – occurs - causing a high risk of burns.
