Where should CNG storage containers not connected for use be located?

CNG storage containers that are not connected for use should be located in outdoor locations primarily for safety reasons. When stored outdoors, the risk associated with potential leaks or accidents is minimized due to increased ventilation and the ability for any escaping gas to dissipate into the atmosphere rather than accumulate in an enclosed space. This reduces the risk of fire and explosion that could occur in confined indoor environments.

Additionally, keeping CNG storage outdoors ensures that there is less chance for hazardous fumes to affect personnel working in nearby areas. This practice aligns with safety regulations and guidelines that emphasize the importance of separation from populated areas.

Storing CNG indoors, in close proximity to operational areas, or under covered parking areas poses a higher risk due to the possibility of gas build-up in case of leaks, which could lead to dangerous situations. Therefore, outdoor locations are the most appropriate and safest option for storing CNG containers that are not in use.
