CGA’s September 2019 Safety Publications (New Releases & Revisions)

October 4, 2019

During September 2019, the Compressed Gas Association (CGA) issued the following new and/or revised safety standards, guidelines, and position statements:

CGA C-9 – Standard Color Marking of Compressed Gas Containers for Medical Use

Released: September 26, 2019 (6th Edition)

Although product labeling and CGA outlet connection identification are the primary and secondary means of identification, color is used as an additional aid for identifying the contents of compressed gas containers for medical use and for designating certain containers for use with specific medical gases.

This standard shall apply to all sizes of containers used with gases for medical use as listed in the U.S. Federal Food Drug and Cosmetic Act. This standard also applies to these gases in Canada.

CGA C-28 – Guideline for Heat Exposure Indicating Systems on Aluminum Alloy Cylinders (Formerly SB-22)

Released: September 26, 2019 (1st Edition)

Aluminum cylinders can be damaged by exposure to temperatures greater than 350 °F (177 °C). Exposure to temperatures greater than these, could weaken the cylinder to such an extent that the cylinder could be unsafe to fill.

Visual examination of the cylinder is not always sufficient to determine if the cylinder has been heat affected. In most cases, overheating from a fire is readily apparent by standard visual examination. However, other sources of heat (electric element, super-heated steam, hot air) could possibly not produce any visual sign or indicator of overheating. Therefore, a system for indicating if aluminum cylinders have been exposed to elevated temperatures is recommended.

This publication applies to high pressure, seamless refillable aluminum alloy cylinders.

CGA G-7 – Compressed Air for Human Respiration

Released: September 26, 2019 (8th Edition)

Special Attribute:

  • Referenced by National Fire Protection Association (NFPA)

This publication presents general information regarding the characteristics and use of compressed air. In order to supply the answers to as broad a cross-section of inquiries as possible, it covers material of a general nature only.

Information is provided relative to the preparation, transportation, handling, storage, and use of compressed air. While the publication deals with compressed air used for human respiration, much of the information is equally applicable to compressed air for other purposes.

It should be used in conjunction with CGA G-7.1 – Commodity Specification for Air, which describes the specification requirements and lists the grades for air and prescribes methods of sampling and analysis.

CGA M-23 – Standard for Regulatory Classification of Medical Device Gases

Released: September 24, 2019 (1st Edition)

This publication provides clarification on the regulatory classification of medical device gas mixtures.

It is designed to assist in meeting existing U.S. Food and Drug Administration (FDA) and Health Canada requirements on device gas classifications, by providing the industry with clarity on the classification of medical device gases to ensure uniform registration and listing across the industry.

CGA PS-38 – CGA Position Statement on Registration of Facilities Filling Open Topped Medical Liquid Nitrogen Dewars for Device Use in the United States

Released: September 24, 2019 (2nd Edition)

Provides CGA position on procedures that a filler of open topped medical liquid nitrogen dewars should follow and whether they need to register with the U.S. FDA as a device manufacturing facility.
