In its natural state, natural gas is clear and odorless, which makes it incredibly dangerous because it’s difficult to detect any leaks. Before utilities pipe it into your home, they add a special heavy odor to the gas, so you can detect even small amounts of it escaping. That’s because even a small leak is serious.
Here’s what you do if you smell gas: turn off any flames, open windows and doors, and get out of your house as quickly as possible. Don’t turn on light switches or use the phone to call the gas company. Gas can easily build up in interior spaces, and the tiniest little spark can ignite it.
Once outside, close the main gas shutoff valve, and use a neighbor’s phone to report the problem. Remember, the smell of gas is there for a reason. Never ignore it, regardless how minor it may seem.
