Gas Line Leak? Act Fast: A Step-by-Step Guide
If you suspect a gas line leak, immediately evacuate the area, avoid using electrical devices or open flames, and call your gas company’s emergency line or 911 from a safe location. Do not attempt to locate or repair the leak yourself.
Evacuate and Alert: The First Steps
Warning Signs of a Gas Line Leak
Be aware of these common indicators: A strong sulfur or “rotten egg” smell. Hissing, whistling, or roaring near gas appliances, meters, or pipelines. Unexplained increase in gas bills or pilot lights that won’t stay lit. Dead/dying vegetation or bubbling in standing water above a buried pipeline.What Not to Do When You Suspect a Gas Line Leak
The Dangers of Inaction
Delaying evacuation or calling for help increases the risk of fire, explosion, and inhalation injuries (including life-threatening outcomes). Even low concentrations of certain gases can cause health effects—so don’t ignore warning signs.The Trade-Off Matrix: DIY vs. Professional Repair
The Practitioner’s Reality Check
Counter-Intuitive Insight: Many people think turning off the gas at the appliance is helpful; however, unless you know where and how to safely operate the main shutoff, doing so can put you in the leak zone longer. If you can safely reach and operate the meter valve from outdoors (and only if trained), you may shut it off—otherwise wait for the utility or fire service.Frequently Asked Questions
Should I call my gas company or 911 first?
From a safe location, call 911 if there is immediate danger (fire/smoke/exposure). Otherwise call your gas utility’s emergency number—if you can’t reach them, call 911. Utilities and emergency services coordinate responses.
Is the rotten-egg smell always present with a gas leak?
Utilities add an odorant (mercaptan) to natural gas, but odour detection isn’t foolproof—sensory fatigue or certain gases without odorants (or high concentrations that overcome smell) make detection unreliable. Evacuate if you suspect a leak even if you’re unsure.
Can I open windows and doors before leaving?
If it’s safe to do so quickly while exiting (and you won’t operate electrical switches), opening doors/windows can help ventilation—but do not linger in the area or use devices inside. Prioritize getting outside quickly and calling for help.
Will the utility come right away?
Yes—utilities treat gas leaks as emergencies and dispatch crews immediately. They will isolate the line, ventilate the area if needed, and repair or advise next steps. Always follow their instructions.
