What should be the maximum capacity of a residential fueling system?

The maximum capacity of a residential fueling system is established to ensure safety and compliance with regulatory standards. A capacity limit of no more than 5 standard cubic feet per minute is appropriate for residential fueling systems because it helps to minimize risks associated with gas leakage and pressure build-up.

This regulation is primarily designed to ensure that residential systems are safe for everyday use, as larger capacities could create a higher risk of accidents and potentially hazardous situations, particularly in residential areas where there may be more unintended exploitation of the fueling system. It allows homeowners to fuel their CNG vehicles efficiently while still adhering to safety protocols and maintaining control over the fueling process.

A capacity greater than 5 standard cubic feet per minute may not be suitable for residential environments due to the complexities of installation, operation, and maintenance, which could require more professional oversight and increase the potential for mechanical failures or operational mistakes. Therefore, establishing a maximum capacity at this level is crucial for residential CNG fueling safety.
