Is it true that gas piping must be electrically bonded to the building ground?

Gas piping must indeed be electrically bonded to the building ground to reduce the risk of electrical shock and to ensure safety. Bonding gas piping helps to equalize the electrical potential between metallic piping and the electrical grounding system of the building. This is particularly important because gas pipelines are often made of metallic materials that can become energized due to faults or other electrical issues in the vicinity.

By bonding the gas piping to the building’s grounding system, it helps to prevent harmful voltage differences that could lead to dangerous electrical shocks for individuals working on or near the gas system. Additionally, proper bonding is often a requirement in national and local building codes, ensuring compliance with safety standards in construction and maintenance practices.
