Liquid Petroleum Gas (LPG) poses significant dangers due to its rapid expansion when vaporized. When LPG is stored as a liquid under pressure, it is in a compact form, but once it is released into the atmosphere, it vaporizes quickly, increasing in volume dramatically. This rapid expansion can lead to the formation of flammable gas clouds, which can result in fire or explosion hazards if there is an ignition source nearby. Thus, understanding the behavior of LPG when it vaporizes is crucial for ensuring safety in environments where it is stored or used.

The other options highlight misconceptions or risks that are not as impactful. For instance, LPG is actually flammable and poses serious risks under typical conditions. It does not require very low temperatures for storage, as it is typically contained in pressurized tanks at ambient temperatures. Additionally, while LPG is stored under pressure, it is not characterized as having low pressure. Recognizing the dynamics of how LPG behaves, particularly its expansion when vaporized, is essential for safe handling and management practices.
