The requirement for how far conduit used to encase an underground gas line must extend beyond the end of the building is established to ensure safety and facilitate proper installation and maintenance. In this case, extending the conduit a minimum of 4 inches beyond the end of the building helps to protect the gas line from potential damage from landscaping, construction, or other activities close to the building's perimeter. This distance also provides enough room for any necessary connections to the gas supply system while minimizing the risk of accidental impacts or compression from soil movement. Adhering to this standard helps ensure the integrity of the gas line and complies with safety regulations.
