What do you do if you suspect a natural gas leak? We've got tips for you.

Recognizing gas leaks

If you’re like most people, you’ve learned to rely on your sense of smell to detect a natural gas leak. In and around your home, that distinctive, sulfur-like odor is in fact a sure sign that natural gas is leaking from an appliance or pipe. But odor is not the only sign, especially on the job site. And in some cases, natural gas leaks don’t smell at all.

National Grid adds the odorant mercaptan to natural gas. This odor, which is similar to sulfur or rotten eggs, helps most people smell a leak. But in some cases, the odor of natural gas can be masked by other smells, or the gas can be stripped of its odor. This is known as “odor fade.”

So be sure to not only rely on your nose, but your eyes and ears as well to detect the warning signs of a gas leak. Be alert for hissing, whistling or roaring sounds; dirt blowing into the air from a hole in the ground; continuous bubbling in water; or a damaged connection to a gas appliance.

Respond safely to a natural gas emergency

If you hit a gas pipeline or suspect a gas leak, protect yourself, your coworkers and the public by taking the following steps:

  1. Leave your equipment behind. Warn others of the danger, and leave the area quickly. Stay away until utility personnel say it is safe to return.
  2. Do not use matches, lighters or anything electrical – even a phone. A spark could ignite the gas.
  3. Do not operate underground pipeline valves or attempt to stop the flow of gas. Never bury a contacted pipeline.
  4. From a safe location, call 911, and then call National Grid at one of the numbers below.
  5. Report the incident to your supervisor.

There’s no such thing as minor damage

Even a slight gouge, scrape or dent in a pipeline or its coating may cause a catastrophic break or leak in the future. Cutting or damaging a wire attached to or running alongside the pipe may make it impossible to locate. Report ALL gas line contacts to National Grid so crews can inspect the line and make necessary repairs.
