Which statement best describes the risk associated with using LPG in basements?

Using LPG in basements poses significant risks due to the potential for gas to displace oxygen, leading to asphyxiation. LPG is heavier than air, which means that in poorly ventilated spaces, such as basements, it can accumulate and reduce the amount of breathable oxygen available. This accumulation creates a hazardous environment that can quickly become life-threatening, especially in the event of a leak.

Proper ventilation is crucial when handling LPG to ensure that any gas that may leak can dissipate safely into the atmosphere, minimizing the risk of an oxygen-deficient environment. In contrast, while soot accumulation is a concern with certain combustion processes, asphyxiation due to displaced oxygen is a more immediate and serious risk associated with using LPG in confined spaces like basements.
