What defines perimeter fencing in CNG installations?

The definition of perimeter fencing in CNG installations is determined by safety standards and regulations that aim to mitigate risk and ensure controlled access to high-risk areas. The correct answer refers to fencing located more than 25 feet from any point of the CNG dispensing system, which is critical for ensuring that any potential hazards associated with the dispensing system are kept at a safe distance from people and property.

This distance serves as a buffer zone, preventing unauthorized access and allowing for safe operations while considering emergency response protocols. The choice of 25 feet is significant because it provides enough space to minimize the risk of accidents and the potential for exposure to high-pressure scenarios or gas leaks.

In addition to establishing safety zones, proper perimeter fencing is also a regulatory requirement that helps facilities maintain compliance with safety codes and prevents incidents related to the handling and dispensing of natural gas. By having a clear demarcation that is a specified distance away from the dispensing system, facilities enhance overall safety and reduce liability.

The other responses either indicate distances that are too far or propose temporary solutions, which do not meet the established safety requirements for permanent CNG installations. Additionally, the emphasis on visibility does not directly relate to the standard for perimeter fencing distance, which is focused primarily on safety protocol rather than
