What is the minimum burial depth underground for gas lines in areas prone to external damage?

The minimum burial depth for gas lines in areas prone to external damage is established to provide adequate protection against physical impact and environmental factors. A burial depth of 18 inches helps ensure that the gas lines are shielded from potential damage caused by surface activities such as digging, construction, or other disturbances. This depth effectively reduces the risk of accidental strikes and provides a safeguard against the elements that could compromise the integrity of the lines.

Consideration for proper depth is crucial in areas with higher risks of external damage, as insufficient burial depth could lead to potential leaks or hazards. This standard aligns with safety regulations designed to minimize the risk of gas line failures.

In contrast, burial depths less than 18 inches may not offer the same level of protection, while those greater than 18 inches, while potentially safer, may not be necessary in all situations, especially if the risk of external damage is carefully assessed. Therefore, the determination of 18 inches strikes an effective balance between safety and practicality in safeguarding gas lines against external threats.
