How does exposure to liquefied petroleum gas affect the body?

Exposure to liquefied petroleum gas (LPG) primarily poses a risk because it can displace the oxygen in the air, leading to an asphyxiation hazard. LPG is heavier than air, which means that it can accumulate in low-lying areas, effectively reducing the amount of breathable air available to individuals.

When inhaled in high concentrations, the gas doesn't provide a direct toxic effect like some other substances might, but its presence can create an environment where there's insufficient oxygen for normal physiological functions. This lack of oxygen can result in symptoms such as dizziness, shortness of breath, and in severe cases, loss of consciousness or suffocation.

Understanding the behavior of LPG and its effects on air quality is essential for firefighters and emergency responders, as they must be aware of the risks when operating near potential gas leaks or in confined spaces where LPG may accumulate.
