Which of the following describes one of the principle dangers inherent in liquified petroleum gas?

Correct Answer: Option D — its low temperature causes frostbite or freezing

Liquefied petroleum gas (LPG) is transported under refrigeration or undergoes rapid auto-refrigeration when released to atmospheric pressure. Contact with this cryogenic liquid causes immediate, severe frostbite and tissue freezing, representing a primary physical hazard to crew members during cargo operations.
