Propane leaks are rare, but they can happen. Knowing what to do if you smell gas can help ensure the situation is resolved safely and quickly.
Since propane is naturally odorless, propane and natural gas distributors use an additive called mercaptan to give it a distinctive smell that makes it easier to detect leaking gas. Most people describe the smell as like rotten eggs, skunk or dead animal.
Mercaptan is a natural gas that is produced by decaying plants, animals and humans (fun fact—it’s one of the compounds responsible for bad breath!). One reason it’s used in propane and natural gas is that the human nose can detect it in extremely small quantities.
Make sure everyone in your home can recognize the odor and know what to do if they smell gas.
If you smell gas and suspect a leak, leave the area immediately.
Avoid all flames or sparks—including lights, appliances, phones or cell phones—which could ignite the gas and trigger an explosion.
Call us, or dial 911 from a safe area, and stay away until help arrives.
If it’s safe to do so, you should turn off the gas at the tank. You should also shut off your tank if there has been severe weather, flooding, or a natural disaster and your tank appears to have moved, or if there appears to be damage to the tank or the gas lines. It’s not hard—but it’s important to familiarize yourself with your tank so you know what to do when it’s an emergency.
