Detecting a Propane Leak

Propane gas leaks are highly flammable and can be easily ignited by a spark or flame. They can result in explosions with devastating consequences. If you use propane appliances at home, it is important that you know how to recognize a leak and fix the problem before it becomes catastrophic.

Propane Safety Tips

The smell of propane is strong and foul, similar to a dead animal, rotting eggs or a skunk’s spray. The odor is deliberately added to propane so you are able to detect a leak. It is important for you and your family to become familiar with the smell. If you detect a leak in your home:

• Immediately extinguish flames or smoking materials, and do not create any sparks.


• Do not turn on lights or appliances, and do not use your land line or cell phone, as these actions could produce sparks.

Propane leaks can cause carbon monoxide poisoning. If you are experiencing headaches, dizziness, loss of muscular control, vomiting or watering of the eyes, have your propane system checked immediately.

• Inform others in the premises and evacuate.


• If you are able, turn off the main gas supply valve on your propane gas tank.


• Contact the fire department or dial 911.


• Do not return to the premises until instructed to do so by emergency response personnel.


• Have a propane service technician perform a comprehensive check on your entire system before turning on any appliances.

Take these proactive steps to prevent leaks:

• Clean furnaces regularly. Check with your propane retailer for cleaning instructions.


• If you suspect your propane appliance has been damaged by water, call a trained technician to check your system.


• When performing renovations or landscaping, refer to the layout of your gas service lines.


• When using gas grills, follow the owner’s manual.
