Propane helps you live comfortably wherever and however you want. This video shows how easy it is to turn your propane tank off, when necessary. Never turn on the gas yourself. Your propane system has some great features that help your family stay safe and comfortable, like the ability to turn off the gas quickly. There are many reasons you may want to turn off the gas. If you smell gas or suspect a leak, turn off your gas only if it is safe to do so. After a storm or a natural disaster, if you suspect something isn’t right with your system — such as a tank has changed position, or a gas line has been bent or damaged — turn off your gas. Never turn on the gas yourself; national safety codes require that a qualified professional inspect your system before turning on the gas again or re-lighting pilots.
