IMPORTANT SAFETY INFORMATION (CONTINUED) WARNING Never open system components while the system is under pressure. Treat all cylinders as full until defueling has been completed. WARNING Never weld or perform any type of "hot work" on any part of a compressed natural gas vehicle unless the compressed natural gas fuel system has been purged with inert gas.
Page 139: Properties Of Natural Gas / Signs Of A Fuel Leak
PROPERTIES OF NATURAL GAS SIGNS OF A FUEL LEAK CNG is a naturally occurring hydrocarbon gas mixture An odorant which smells like rotten eggs is added to which consists primarily of methane. This gas is lighter than compressed natural gas to aid in detection of a leak. If you air, which means if gas were to leak, it would float upwards notice this kind of lingering odor coming from your vehicle, and quickly dissipate into the atmosphere.
