LNG is a cryogenic liquid that needs to be handled with care to avoid skin cold burns. It must be distributed and stored in specialized equipment and tanks in order to keep the fuel in a liquid state.
Handled properly, LNG can be safely stored, distributed and dispensed throughout transportation supply chains in an efficient manner. Decades of industry experience has demonstrated that, LNG poses no more risks than other transportation fuels being used today.
LNG tankers have been run for decades, during that period occasionally experienced loss of containment, suffered weather damage, been subjected to low temperature cargo spillage, suffered engine room fires, and been involved in serious collisions with other vessels - and no single LNG cargo explosion reported.
LNG is not toxic, not carcinogenic and less flammable than oil; its vapors are lighter than air and therefore rapidly disperse into the atmosphere and do not accumulate on the floor of contained areas.
LNG and natural gas are both hydrocarbons which will burn when exposed to air and ignited by a suitable source of ignition. In this regard, LNG is no different than other common petroleum fuels such as gasoline, kerosene and diesel. LNG does not burn or explode by itself, for natural gas to become combustible is needed to be in vapor form and mixed with air in the particular range of 5-15% volume concentration in air.
