Most liquified gas cargoes are flammable, and are carried at or close to their boiling point. What will happen if they are released into the atmosphere?

Correct Answer: Option B — burn, if it's within its flammable range and has an ignition source

Liquefied gases are stored near their boiling points and are highly flammable. If released, they rapidly vaporize and mix with air. If this mixture falls within the flammable range and encounters an ignition source, it will burn, posing a severe fire hazard to the vessel, crew, and surrounding terminal environment.
