The purpose of this publication is to provide a standard for small, stationary, insulated carbon dioxide systems.
It is intended to assist designers, engineers, distributors, restaurant personnel, inspectors, other users, and all interested parties
This standard contains minimum requirements and recommended practice for the design, construction, installation, operation, and maintenance of small, stationary, insulated carbon dioxide systems from lhe fill connection to the storage container outlet connection valve. See Figure 1. These systems are primarily used for supplying
carbon dioxide gas at beverage dispensing sites and can also be used in greenhouses, by welding fabricators,
and for other applications. Additional information on carbon dioxide is published in CGA G-6, Carbon Dioxide,
and CGA AV-7, Characteristics and Safe Handling of Carbon Dioxide [1, 2].4
The system shall be designed so the container does net become liquid full at the pressure setting of the pres-
sure relief device (PRD) and shall discharge to the outside of the building.
While this standard is to be used as a guide for user installations, final approval of the design, equipment, ap-
purtenances, and installation rests with regulatory authorities with jurisdiction in this area.
