As its boiling point is below room வெப்பநிலை, LPG will evaporate quickly at normal temperatures and அழுத்தம்s and is usually supplied in pressurized எஃகு vessels. They are typically filled to 80–85% of their capacity to allow for வெப்ப விரிவு of the contained liquid. The ratio of the densities of the liquid and vapor varies depending on composition, pressure, and temperature, but is typically around 250:1. The pressure at which LPG becomes liquid, called its ஆவியமுக்கம், likewise varies depending on composition and temperature; for example, it is approximately 220 கிலோpascals (32 psi) for pure பியூட்டேன் at 20 °C (68 °F), and approximately 2,200 கிலோpascals (320 psi) for pure புரொப்பேன் at 55 °C (131 °F). LPG in its gaseous phase is still heavier than புவியின் வளிமண்டலம், unlike இயற்கை எரிவளி, and thus will flow along floors and tend to settle in low spots, such as basements. There are two main dangers to this. The first is a possible explosion if the mixture of LPG and air is within the explosive limits and there is an ignition source. The second is suffocation due to LPG displacing air, causing a decrease in oxygen concentration.

A full LPG gas cylinder contains 86% liquid; the ullage volume will contain vapour at a pressure that varies with temperature.
