The information contained in this handbook was obtained from technical sources believed to be reliable, and is based on technical information and experience available at the time of publication from members of the Compressed Gas Association, Inc. and others. Readers are cautioned to refer to any applicable CGA technical publications and obtain the most up-to-date edition. These publications are reviewed on a periodic basis and are the official statement of policy by the Association on a particular matter. 

A complete list of the publications, standards, and audiovisual training programs of the Compressed Gas Association, Inc., can be found with a brief description of the coverage of each as an appendix in Part IV of this Handbook,... 

Many of the detailed engineering aspects of mechanical integrity are covered by codes and standards generated by a wide variety of associations. Useful references not mentioned in the OSHA excerpt above include those published by organizations such as the American Institute of Chemical Engineers, the Chemical Manufacturers Association, the Chlorine Institute, the Compressed Gas Association, and publications from various property insurance associations. 

The Compressed Gas Association (CGA) is composed of members from firms that produce and distribute compressed, liquefied, and cryogenic gases. The association develops and publishes recommendations to improve safety concerning the transportation, storing, and handling of gases. The CGA provides handbooks, technical publications, videotapes, and posters relating to safety. 

The Compressed Gas Association, Inc. (CGA) issues general industry standards and recommendations for compressed gases along with a number of publications, which are concerned with highly specialized aspects of the... 

Lastly, a listing providing descriptions of all publications and audiovisuals available from the Compressed Gas Association, Inc. is provided. 

Neither the Association, its members, nor the publisher guarantee any results, make any representations regarding the accuracy of, or assume any liability or responsibility in connection with, the information or suggestions contained in this handbook. It should not be assumed that every acceptable commodity grade, test or safety procedure or method, precaution, equipment or device is contained within, or that abnormal or unusual circumstances may not warrant or suggest further requirements or additional procedures.

The Association advises readers that the CGA technical publications remain the official statement of policy on a particular matter. Reference is made throughout this text to the numerous technical publications published by the Compressed Gas Association. Some of these publications have been incorporated by reference into federal, state, provincial, and local regulations. 

P-6 Standard Density Data, Atmospheric Gases and Hydrogen, Density data recommended in this publication were compiled by the Compressed Gas Association to provide uniform values of liquid and gas density for atmospheric gases and hydrogen for the benefit of suppliers and users of these commodities. Tables present standard density data and volumetric conversion factors. (4 pages)... 

The close superposition of C02/polymer isotherms at various tempo-atures, when plotted vs. activity, sugg ts that most of the apparent temperature dependence of the isotherms plotted vs. pressure is related to the activity change of CO2 with temperature. At constant activity, die actual mixing of CO2 with PMMA, PC, or PVBz appears to be nearly athermal i.e., the energy of interaction of CO2 with these polymers seems to be essentially that associated with the compression of the gas to its molar volume in the sorbed state. This aspect of polymer interactions with CO2 will also be consicfored further in forthcoming publications. 

A gas data and safety sheet for carbonyl difluoride has been produced by the British Compressed Gases Association [277] and the compound is described in the Matheson publication, "Guide to safe handling of compressed gases [1347], and the ACGIH Documentation of the Threshold Limit Values for Substances in Workroom Air [38,39].
