Who is identified as the person controlling CNG immediately before its ignition?

The person controlling CNG immediately before its ignition is identified as the ultimate consumer. This is because the ultimate consumer is the individual or entity that uses the CNG for its intended purpose, such as operating equipment, heating a facility, or powering a vehicle. At the point of ignition, they have direct control over the CNG, determining how and when it is utilized.

In this context, the fuel operator and gas technician may play significant roles in the handling and delivery of CNG, but they do not have control over the specific usage and ignition of the gas once it reaches its final intended destination. Similarly, a distribution manager oversees the operations within the supply chain but is not involved at the ignition point where the end-use occurs. Thus, it is the ultimate consumer who is directly responsible for the CNG at the moment before it is ignited, validating why that choice is the correct one.
