What is the minimum distance for gas piping below a commercial parking lot?

The minimum distance for gas piping below a commercial parking lot is established to ensure safety and prevent potential hazards associated with gas leaks or damage to the piping. Placing gas piping at least 24 inches below a parking lot surface helps protect the piping from vehicle loads and the risk of impact or damage caused by vehicles driving over the area. Additionally, this depth reduces the potential for the accumulation of harmful gases in case of leakage, as the soil can act as a natural barrier, allowing for proper dissipation. The 24-inch depth recommendation is based on industry standards that prioritize safety and regulatory compliance concerning gas utilities, making it essential for gas technicians to adhere to these guidelines when installing piping in such environments.
