What term describes a system including various safety and operational devices intended for use in CNG applications?

The term that describes a system including various safety and operational devices intended for use in CNG applications is "CNG system." This terminology encompasses all the components and equipment necessary for safely managing compressed natural gas operations, including storage facilities, delivery trucks, safety mechanisms, and usage protocols. A CNG system is specifically designed to ensure that the handling and utilization of compressed natural gas are efficient, safe, and reliable.

In this context, other options may suggest related constructs but do not fully encapsulate the diverse array of devices and technologies involved in CNG operations as comprehensively as "CNG system." For instance, "CNG framework" might imply a structural concept but does not explicitly convey the operational and safety aspects tied to gas handling. Similarly, while "CNG network" could refer to a system of interconnected pathways or facilities, it lacks the specificity regarding operational devices. "CNG infrastructure," though relevant, generally pertains to physical installations and support mechanisms but is less focused on the operational aspect of safety and control mechanisms essential in CNG applications.
