Where must CNG compression, storage, and dispensing facilities be located?

CNG compression, storage, and dispensing facilities are required to be located outdoors for several important reasons related to safety and regulatory standards. Compressed natural gas is highly flammable, and having these facilities outdoors helps mitigate the risks associated with potential leaks and the accumulation of gas in confined spaces, which could lead to explosive conditions.

Additionally, outdoor locations provide better ventilation, allowing any escaping gas to dissipate freely into the atmosphere rather than accumulating in enclosed areas. Regulatory standards often mandate the siting of CNG facilities in open air environments to lower the safety risks to both personnel and surrounding facilities.

While other choices might suggest shelter designed to protect equipment from environmental factors, the prevailing requirement for these facilities is that they operate in outdoor settings to enhance safety and comply with best practices in managing flammable gases.
