Gas Leak Signs: What Does a Gas Leak Smell Like?

Gas leaks are incredibly dangerous, and knowing how to detect one could save your life. Here, we’ll cover what a gas leak smells like, physical symptoms to watch out for, and what to do if you suspect a gas leak in your home.

What a Gas Leak Smells Like

You may already know that natural gas, on its own, is completely odorless. So, how can you smell something that has no smell? With help from gas companies. For safety reasons, gas companies add a chemical called mercaptan to give natural gas a distinct sulfur-like smell, similar to rotten eggs. It’s that added chemical and the resulting odor that can alert you to the presence of a gas leak.

Other Signs That Indicate a Gas Leak

A sulfur-like smell isn’t the only indication that you may be dealing with a gas leak. Here are a few additional gas leak signs to be on the lookout for:

Hissing or Whistling Sounds

If you hear a hissing sound near gas appliances, such as your stove or gas meter, it could be the sound of gas escaping.

Dead or Dying Plants

Gas leaks can kill vegetation. If you notice plants near a gas line suddenly dying, it’s a possible sign of a leak.

Bubbles in Standing Water

Bubbles in puddles or other areas with standing water could be signs of gas escaping from underground lines.

Unexplained Gas Bill Increase

If your gas bill suddenly spikes without any apparent reason, it could point to a leak. That’s because even gas escaping from lines still registers on your bill.

Physical Symptoms

Here are a few of the most common physical symptoms exhibited by those who have been exposed to natural gas:

• Headache and dizziness
• Confusion
• Nausea and vomiting
• Breathing difficulties

If you suspect a gas leak, it’s important to also keep an eye on any pets in the house, watching for signs of lethargy, breathing issues, and vomiting.

What to Do if You Suspect a Gas Leak

If you suspect a gas leak, take immediate action. Here’s what you should (and shouldn’t) do to stay safe and healthy:

1. Evacuate

If you notice any signs or smell a gas leak, leave your home immediately; do not wait to investigate further. Ensure everyone in the household, including pets, gets out safely.

2. Don’t Use Open Flames or Electronics

Gas is highly flammable; the slightest spark can ignite it. Therefore, don’t use open flames, turn on lights, use appliances, or even touch your phone while still inside the house. Wait until you’ve exited and are a safe distance away before calling for help.

3. Don’t Look for the Source of the Leak

All too often, homeowners try to locate the source of the gas leak. Doing so could put you in further or increased danger. During a suspected gas leak, the priority is to get to a safe location.

4. Contact Emergency Personnel

Call your gas company’s emergency line or a local emergency number. Again, don’t call from your cell phone inside the house, as a tiny spark could ignite the gas.

5. Seek Medical Attention

If you or anyone else is experiencing symptoms like difficulty breathing, dizziness, or headache, consult a healthcare professional as soon as possible. Prolonged exposure to natural gas can have severe health consequences; it’s always better to err on the side of caution.
