If you own a gas grill or burner powered by propane (such as a turkey fryer), you need to know how to check the gas line for leaks before you start cooking. If any gas is leaking out when you ignite the grill or burner, you could start a fire, or worse, set off an explosion.
The first thing to do is make a visual inspection. Jackie Mason of the Propane Council of Texas told us to make sure that there's no cracks or rust on the tank, which can compromise its structural integrity. Then look for holes, wears, or tears on the hose—squirrels or other wild animals may enjoy nibbling on it.
From there, a simple test can tell you whether you have any leaks. We follow the guidance of the National Institutes of Health.
