Is It a Propane Leak or “Just” a Rotten Egg?

A rotten egg smell when you have propane is more than a kitchen emergency!

Propane is widely used for heating, cooking, water heaters, and other appliances. It’s efficient, safe, and reliable when your system is installed correctly and maintained by professionals. But like any fuel source, problems can arise if the equipment is damaged, aging, or not correctly maintained.

A small propane leak can create several issues. First and most importantly is the safety risk involved. Propane is highly flammable, and if gas builds up in an enclosed area, it can create a fire or explosion hazard. Leaks can also cost you money. If propane is escaping from your tank or lines, you’re literally losing fuel and paying for gas you never got to use. In some situations, propane exposure can also cause dizziness, headaches, and nausea.

One of the most common signs of a propane leak is the smell of a rotten egg. While propane itself is naturally odorless, suppliers add a chemical called ethyl mercaptan. This creates a sulfur smell that most people associate with rotten eggs and propane.

Thankfully, smell isn’t the only clue that something’s wrong. You may hear a hissing or whistling sound near the propane tank, line, or appliance connection. You may also see visible damage, such as rust or a dent, on the tank, regulator, or piping. Outside, you may even see dead vegetation near buried propane lines where gas has been leaking into the soil. We recommend that customers research gas and carbon monoxide detectors. We make no specific recommendations on these.

If you think you might have a propane leak, don’t ignore it. Leave the area right away and avoid using electrical switches, appliances, or anything that could create a spark. Once you are at a safe distance, contact Advanced Propane for an emergency inspection and service.
