Question 1375 Deck General

70% to pass

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?

A result in sloshing in the tank which could make the ship unstable
B burn, if it's within its flammable range and has an ignition source
C freeze and possibly cause structural damage
D allow air to enter the system causing polymerization
AI Explanation

The correct answer is B) burn, if it's within its flammable range and has an ignition source. When liquefied gas cargoes are released into the atmosphere, they will rapidly vaporize and mix with the surrounding air. If the gas concentration falls within the flammable range and an ignition source is present, the vapors will burn. This is a key risk with handling liquefied gases that must be carefully managed. The other options are incorrect: A) is about sloshing, which is a stability issue, not a release hazard. C) is incorrect as the rapid vaporization and expansion would not cause freezing. D) is incorrect as air entry would not cause polymerization in this context.
