|LNG Risk Assessment
A new two-page fact sheet has been released by AAF. Clearly stated and fully sourced, it provides a different view of those high-tech gas liquification facilities and tanker superships touted on all the API TV commercials.
A selection of facts drawn from the paper:
Liquefied Natural Gas (LNG) is methane in the form of a bubbling, super-cold liquid (minus 259 degrees Fahrenheit). By contrast, Compressed Natural Gas is highly pressurized methane vapor.
LNG is the form that natural gas takes when it is exported overseas on tanker ships. To a lesser extent, LNG is used as vehicle fuel in, for example, long-haul trucks.
If LNG spills into water, it explodes.
If LNG spills on the ground, it turns into rapidly expanding clouds of vaporizing methane that can asphyxiate by displacing oxygen and flash-freeze human flesh.
If ignited at the source, these vapors become flaming “pool fires” that burn hotter than other fuels and cannot be extinguished.
Drifting in the wind, an ignitable vapor cloud can threaten large populations.
Highly volatile LNG cannot be odorized, so there is no warning of a leak.
The ongoing prohibition on LNG facilities in New York State was the result of a deadly explosion in 1973 that blew apart an empty LNG tank in Staten Island and killed 40 people.
