When an underground natural gas leak is suspected, which action is typically recommended?

• A. Do nothing and observe
• B. Evacuate and call the gas utility or emergency services
• C. Start digging to locate the leak
• D. Cover the area with soil

Answer: (B)

The key idea is that a suspected underground natural gas leak demands immediate evacuation and professional help. Gas can travel through soil and collect in confined spaces, and it is highly flammable—igniting any spark can cause a serious explosion. By evacuating people to a safe distance and calling the gas utility or emergency services, you remove everyone from danger and enable trained responders to locate the source and shut off the gas safely. Trying to locate or fix the leak yourself, digging, or covering the area can spread gas, trigger ignition, or trap it, increasing risk. So the recommended action is to leave the area and contact the appropriate authorities right away.
