Which statement correctly describes the primary risk of liquefied petroleum gas exposure?

• A. It increases oxygen levels in the air
• B. It causes dehydration
• C. It displaces breathing air
• D. It acts as a stimulant

Answer: (C)

Exposure to liquefied petroleum gas mainly risks asphyxiation by displacing the breathable air. LPG is heavier than air, so leaks tend to settle in low areas and accumulate, reducing the concentration of oxygen people can breathe. When oxygen levels drop, you can see dizziness, confusion, fainting, and even loss of consciousness, especially in enclosed spaces. This is not about dehydration or stimulating effects, and it does not increase the amount of oxygen in the environment. The focus in safety terms is to get people to fresh air and ventilate the area, while eliminating ignition sources and using appropriate respiratory protection if entry is necessary.
