What is the primary reason for protecting the operating end of CNG containers and related equipment?

Protecting the operating end of CNG containers and related equipment is primarily important to prevent collision damage. This is critical because CNG containers are designed to withstand significant pressure and must remain intact for safe operation. If the operating end of these containers is damaged through a collision, it can lead to gas leaks, which pose serious safety risks, including explosions or fires. Ensuring this area is protected helps maintain the integrity of the storage system and ensures safe transport and delivery of compressed natural gas.

While preventing collision damage is essential, considerations like operational costs, aesthetic appeal, and ease of access are secondary in comparison to the overarching need for safety and functionality in handling CNG systems. Each of those factors plays a role in logistics and design but does not directly address the imperative safety measures associated with the operating end of CNG containers.
