The purpose of this standard 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. Because portable tanks built to U.S. Department of Transportation (DOT) standards require special facilities to ensure they are not overfilled, this standard does not cover their use.
This standard contains minimum requirements and recommended practice for the design, construction, installation, operation, and maintenance of small stationary insulated carbon dioxide systems from the fill connection to the carbon dioxide container gas outlet regulator. 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].
