Know your fuel
Gas grills can be fueled using propane in a portable cylinder or natural gas that is delivered via underground pipes from a home's natural gas supply to a professionally installed grill.
Although some 52 percent of gas grill owners have their LP (liquid propane) cylinders refilled for them, 27 percent find it more convenient to take their empty cylinder to an LP exchange center at a nearby store to get a new, filled cylinder. However, 40 percent of all gas grill users own two or more LP cylinders so they never have to risk running out of gas!
Gas grilling is now safer than ever thanks to a mandate from the National Fire Prevention Association in 2002 that only cylinders with an overfill prevention device (OPD) may be exchanged or refilled. This prevents the cylinder from being filled more than 80 percent -creating a potential fire hazard when rising temperatures cause propane gas to expand and unintentionally be released into the air.
