Galvanized pipe is used for natural gas lines and pressure vent lines, and for electrical conduits. As a water supply or drain pipe, it is subject to rusting over time.
Nitrogen is heavier than air, and is an inert gas - it will not burn or explode.In fact nitrogen is used to prevent fires in certain circumstances. Depending on the size of the leak, care must be taken not to inhale as the nitrogen will replace the oxygen thus causing suffocation. Ventilate before entering a building where gas leaks are suspected
Try Nitrogen (For natural gas lines NOT cars /trucks etc)
