What must the storage and compression area be completely enclosed by?

The storage and compression area must be completely enclosed by fencing to ensure security and safety. Fencing provides a physical barrier that helps prevent unauthorized access to potentially hazardous materials and equipment used in compressed natural gas operations. This is crucial in maintaining safety standards and protecting both workers and the public.

Fencing can be made from various materials designed to withstand environmental conditions while providing clear visibility of the contained area. It serves not only as a protective measure but also as a regulatory requirement in many regions, including Texas, to ensure compliance with safety regulations governing the handling of compressed natural gas.

Other options like barbed wire or concrete walls may offer security or containment as well, but fencing is the most common and practical choice for operational areas requiring a balance of accessibility and security. Fencing typically allows for easier access for maintenance and monitoring while still providing the necessary protective barriers.
