What is a necessary feature for valves and fittings in CNG facilities?

Clear access of 3 feet is an essential feature for valves and fittings in CNG facilities because it ensures that personnel can safely and easily access equipment for maintenance, inspection, and operation. This space minimizes the risk of accidents and allows for efficient work in emergency scenarios, ensuring compliance with safety regulations and facilitating quick response to potential leaks or failures. Having unobstructed access is critical, especially in emergency situations where quick action is necessary to mitigate risks.

In contrast, while automatic inspection tools, continuous monitoring systems, and remote-operated controls may enhance operational efficiency and safety, they do not address the immediate physical accessibility needs that are crucial for personnel involved in the daily functions and emergency responses at CNG facilities. Clear access is a foundational requirement that supports all other practices and technologies in place.
