What is one of the principal dangers inherent in liquefied petroleum gas?

A its low temperature causes frostbite or freezing
B the way it reacts with sea water
C as it warms up it becomes heavier than air
D the strong odor it produces
AI Explanation

The correct answer is A) its low temperature causes frostbite or freezing. Liquefied petroleum gas (LPG), such as propane or butane, is stored under pressure and is extremely cold, around -40°F (-40°C). If LPG is released, the rapid expansion and evaporation can cause severe frostbite or freezing of exposed skin and tissues. This low temperature hazard is one of the principal dangers of handling LPG. The other options are incorrect: B) the way it reacts with sea water is not a principal danger, C) as LPG warms up it becomes lighter than air, not heavier, and D) the strong odor is actually an intentional safety feature to help detect leaks, not a principal danger.
