Liquefied natural gas, or LNG, is natural gas that has been cooled to minus 160° C (minus 260° F) at atmospheric pressure and reduced to a liquid state that is 1/600th its original volume. LNG is clear, colourless, and odourless. LNG is non-corrosive and non-toxic.
The potential hazards of LNG are the result of its basic properties including its cryogenic nature and dispersion and flammability characteristics. Due to its cryogenic nature, LNG will freeze any material it contacts. As a liquid, LNG cannot explode and is not flammable. Only when LNG is warmed and returns to its gaseous state (i.e., natural gas), is mixed with air, and comes into contact with an ignition source, does the mixture become flammable or explosive (in a confined environment). Before any of these hazards can be realized, a release of LNG would need to occur.
