What is the maximum volume a single compressed natural gas (CNG) container can hold according to regulations?

The correct answer is based on regulations that govern the storage and transportation of compressed natural gas (CNG). According to these regulations, a single CNG container may hold a maximum volume of 381 standard cubic feet (SCF). This limit is established to enhance safety by ensuring that individual containers do not exceed certain capacities, minimizing risks during transport and usage.

The regulatory standard takes into account the safety margins necessary for handling CNG, which is a highly flammable fuel, as well as the need to prevent overloading and ensuring proper pressure management within storage systems. Containers above this specified volume could pose significant safety risks, including increased potential for leaks or explosions in the event of a failure.
