Standard for Small Stationary Insulated Carbon Dioxide Supply Systems (Corrected 3/16/2023)

This publication addresses the hazards specifically associated with small stationary insulated carbon dioxide supply systems.  The purpose of this publication is to provide a standard for small stationary insulated carbon dioxide systems with the capacity of each container being 1000 lb (454 kg) or less. It is intended to assist designers, engineers, distributors, restaurant personnel, inspectors, other users, and all interested parties.   This publication does not cover portable tanks built to U.S. Department of Transportation (DOT) standards because they require different procedures and equipment to ensure they are not overfilled.  While this standard is to be used as a guide for user installations, final approval of the design, equipment, appurtenances, and installation rests with the authority having jurisdiction (AHJ) in this area.
