Why are protective measures required for underground piping systems?

Protective measures for underground piping systems are essential to prevent ignition, particularly when dealing with combustible gases like compressed natural gas (CNG). The underground environment poses unique risks including potential leaks and exposure to various factors that could trigger an ignition source. By implementing protective measures, such as proper materials, coatings, and installation practices, the likelihood of a leak igniting is significantly minimized.

Moreover, safety practices may include ensuring adequate ventilation, using appropriate detection systems, and monitoring for potential leaks, all aimed at maintaining a safe environment. This focus on preventing ignition is vital because even a small leak in a system carrying flammable materials can lead to catastrophic incidents if ignition occurs. Such protective measures are critical for safeguarding both the infrastructure and the surrounding community.

While enhancing efficiency, ensuring long-term operation, and reducing maintenance costs are important considerations for any piping system, these factors do not directly address the immediate safety risks associated with igniting flammable gases, making fire prevention the primary focus for protective measures in this context.
