LNG – Properties & Hazards

Click here to read YEC SWP-106.

Liquefied natural gas (LNG) is natural gas that is cooled to -160°C (–260°F) to form a cryogenic liquid.

LNG is comprised of 4 main components:

Methane; 83% - 99%
Ethane; 1% -13%
Propane; 0.1% - 3%
Butane; 0.2% - 1%

LNG occupies 1/600th it’s volume in a liquid state.

LNG has an expansion rate of 600:1 (liquid to vapour).

LNG is odourless, colourless, non-corrosive, and non-toxic.

LNG is lighter than air.

LNG is not flammable in the liquid state.

LNG release results in evaporation and formation of a visible vapour cloud.

Ignition temperature is approx. 537°C (1000°F).

Flame temperature is approx. 1370°C (2500°F).

LNG vapour is non-toxic; but is an asphyxiate.

As LNG vapour concentrations rise, the LFL (5%) will be reached long before the dangers of O2 deprivation are present.

LNG vapour is flammable when mixed with air. The flammable range is 5%; lower flammable limit (LFL) to 15%; upper flammable limit (UFL).

LNG – Properties & Hazards

POTENTIAL HAZARDS	POTENTIAL INJURIES OR DAMAGE
Contact with LNG	(Cold) burns and frostbite.
Contact with LNG equipment/piping; cold surfaces	Skin adhesion and frostbite.
LNG (vapour) release	Breathing discomfort; frostbite; asphyxiation. Fire or explosion.
High pressure	Bodily injury

There is also a cryogenic hazard to equipment & structures.

When LNG spills on the ground or water it vapourizes quickly and leaves behind no residues.

LNG released to the ground or water will result in a visible cloud as the LNG warms.

LNG will evapourate 5X faster in water.

Vapour cloud size and shape depend on wind speed.
