How must the operating end of a CNG container be shielded from vehicular traffic?

Answer: C — It needs barriers extending at least 24 inches beyond it.

The operating end of a CNG container must be shielded from vehicular traffic to ensure safety in case of an incident. Barriers extending at least 24 inches beyond it serve as a physical barrier that can prevent vehicles from coming too close to the operational area. This distance provides a buffer zone that reduces the risk of accidental collisions, which could jeopardize the safety of personnel and equipment. While protective railings, fluorescent paints, and traffic cones may also contribute to safety measures, they do not provide the same level of physical protection as barriers. The specified dimension of 24 inches is designed to create a clear separation between vehicular traffic and the potentially hazardous area associated with CNG operations. This approach aligns with best practices for safety in environments where flammable gases are handled.
