Michael Petruccelli says; The National Fire Protection Association offers several safety tips for propane & charcoal grills. Before using a propane grill for the first time each year, and at the close of grilling season, check the gas tank for leaks. Apply a light soap and water solution to the hose. If bubbles are released, there most likely a propane leak. Be sure to get the grill serviced by a professional before using it again.
