Which of the following statements is correct regarding LP gas?

LP gas, or liquefied petroleum gas, is indeed heavier than air. This characteristic is important for safety and handling considerations. When released, LP gas tends to accumulate in low-lying areas because it is denser than air, which can pose a risk of fire or explosion in confined spaces. Understanding this property helps professionals in the HVACR field take appropriate precautions when working with LP gas, such as ensuring adequate ventilation and employing proper gas detection measures in case of a leak.

The other statements do not correctly describe LP gas. For instance, LP gas is not the same as natural gas; they have different chemical compositions and properties. LP gas can be used in furnaces, making it a versatile fuel option for residential and commercial heating systems. Additionally, while LP gas can be used in portable appliances, it is not limited to them alone, as it is also used in many stationary applications, including home heating and cooking appliances.
