A liquefied natural gas (LNG) spill can happen during an accident or an intentional act.
If this cooled liquid is released from a storage facility, pipeline, or LNG transport ship, then it begins to warm.
As LNG warms above its storage temperature, the liquid begins to vaporize.
If a spill occurs and the vapor does not ignite, it would build to higher concentrations.
According to the 2004 Sandia report, this is of special concern to ship and pilot-boat crews, emergency response personnel or others who are exposed in a marine environment.
