Despite accidents, propane grills are safe when operated correctly, according to the Florida Propane Gas Safety, Education and Research Council. The organization reports that propane tanks are 20 times more puncture-resistant than tanks filled with other types of fuel, such as gasoline and ethanol. The durability of propane tanks makes leaks less likely than in other types of fuel containers.
Propane leaking from a tank dissipates into the air but can ignite. When it initially is released, it has a strong smell similar to rotten eggs. Gas from the leak could ignite and cause an explosion if there is a spark, flame or heat source nearby, such as a person smoking.
It’s possible to test for propane gas leaks using a mixture of soap and water. Conduct the test outside, away from a house or building. Start the test with the propane tank in the off or closed position by turning a valve on the tank. Place the mixture in a spray bottle and spray along all hoses connected to the propane tank. Turn the tank on while looking for soap bubbles from the hose or the connections. A leak exists if bubbles are visible. Turn the tank off. Discontinue use of the grill if there is a leak, and contact the manufacturer for repair options. Solutions include replacing the tank, hoses or connections.
Never grill indoors, including inside a garage. Never disconnect or connect a propane gas tank when a grill is in use or hot. Make sure controls on the grill are in the off position when changing tanks. Check grill hoses periodically for deterioration. Also check propane tanks for rust, dents and punctures. If possible, purchase propane tanks from merchants specializing in propane-related sales and service. The merchants can answer questions about avoiding leaks and the proper operation of your grill. Refrain from smoking around the grill and keep other flammables away.
