One minor caveat, though: LNG and methane are not quite the same thing,
and the presence of modest percentages of higher hydrocarbons in LNG
changes its behavior and its safety issues somewhat. In particular, those
extras are less volatile than methane, and so an evaporating spill will
gradually get richer in them, and the result can be a BLEVE -- the
residual mixture can superheat in conditions where straight methane
wouldn't.
