You say LNG is not combustible or explosive in liquid state. Would a spill into 10C Howe Sound or a 30C atmosphere, not result in LNG immediately boiling into a combustible/explosive vapour?

Hi David,

In order for a fire to happen, a number of things must occur simultaneously: there must be a loss of containment of LNG, the right fuel to air ratio (five-to-15 per cent) and there must be a spark. These conditions are highly unlikely to occur given the complex containment systems, double-hull protection and emergency shut-off, and fire protection systems on LNG carriers, the local marine expertise and the weather conditions that are common in a large fjord like Howe Sound.
