According to regulations, how far must filling connections be from any sources of ignition?

In the context of the safe handling of compressed natural gas (CNG), regulations require filling connections to be located at least 10 feet away from any sources of ignition. This safety measure is critical because CNG is a flammable gas, and minimizing the risk of igniting it during refueling operations is essential to ensure the safety of both drivers and the surrounding environment.

By maintaining a distance of 10 feet, it helps to mitigate the potential hazards associated with accidental ignition. Sources of ignition may include open flames, electrical sparks, heated surfaces, or any other potential trigger that could cause combustion. This distance aims to create a safe buffer zone during the refueling process, thereby enhancing overall safety protocols in CNG operations.
