This publication covers the design, location, installation, operation, and maintenance of insulated liquid car-bon dioxide supply systems located at user sites. The system covered is from the container fill connections to the user?s process piping.

NOTE – Small, stationary, insulated carbon dioxide systems with containers having individual capacities of 1000 lb or less and designed, manufactured, and certified in accordance with American Society of Mechanical Engineers (ASME) Boiler & Pressure Vessel Code, Section VIII, Division 1 requirements are not covered by this publication, refer to CGA G-6.5, Stand-ard for Small, Stationary, Insulated Carbon Dioxide Supply Systems [1, 2].

NOTE – Many of the provisions and design philosophies in this publication apply to storage units in production and depot service. However the operation, operating conditions, and control systems of those units may require further engineering, controls and safety equipment than required by storage units at a user site.

It also contains minimum requirements and recommended practices for the design, construction, installation, operation, and maintenance of such systems.

This publication is intended to serve as a guide for regulatory authorities in writing regulations and to assist designers, inspectors, and other interested parties.
