What can natural gas do to someone if it is leaking?

• A. It displaces oxygen in the air and can cause illness or suffocation.
• B. It will immediately explode.
• C. It will have no effect on people.
• D. It will evaporate without any hazard.

Answer: (A)

Natural gas can displace the oxygen in the air. When it leaks, especially in enclosed or poorly ventilated spaces, the room can have less breathable O2, which can cause symptoms like headache, dizziness, confusion, or fainting, and in severe cases suffocation. The odor added to gas helps you notice leaks, but it doesn’t remove the hazard. The gas is flammable, so a leak can lead to an explosion if there’s a spark or flame, but that risk is about ignition, not the immediate effect of the gas on a person. So, a leak can seriously affect air quality and safety rather than having no effect or evaporating harmlessly.
