This video teaches you what to do if you ever suspect a gas leak. Propane has an added odorant that smells like a skunk’s spray, rotten eggs, or a dead animal. This distinctively unpleasant smell is a safety feature of your propane system. If you smell a leak, have everyone get outside and move away from the house. Put out all smoking materials and other open flames. Do not operate lights, appliances, telephones, or cell phones—as they could create a spark, or ignition source. If it is safe to do so, turn off the main gas supply valve on your propane tank. Call your propane retailer, 911, or fire department right away from a safe area. Do not return to your home until a qualified professional says it’s safe.
