Gas piping can be used as the grounding conductor if the building ground isn't close by. Is this statement true or false?

The statement is false. While gas piping systems are metallic, they are not considered suitable grounding conductors in electrical systems according to the National Electrical Code (NEC). The NEC specifically states that gas piping should not be used as an equipment grounding conductor due to potential safety hazards.

Using gas piping for grounding poses several risks, including compromising the integrity of the gas system and creating a path for fault current that could lead to unwanted ignitions or explosions. It is essential that a dedicated grounding electrode system, such as ground rods or grounding plates, be used to ensure the safety and stability of the electrical system in a building.

Additionally, appropriate grounding methods are critical for maintaining the reliability and safety of the electrical systems and preventing electrical hazards. Thus, it is important to adhere strictly to established codes and standards which dictate proper grounding practices.
