November 19, 2020

During October 2020, the Compressed Gas Association (CGA) issued the following new and revised safety standards, guidelines, position statements, and safety alerts:

CGA G-1.7, Standard for Storage and Handling of Calcium Carbide in Containers

Released: October 9, 2020 (6th Edition)
Special Attribute: Referenced by NFPA (National Fire Protection Association)

This standard covers the storage and handling of calcium carbide in containers from the calcium carbide manufacturer to the point of use. The purpose of this safety publication is to provide information on the storage and handling of calcium carbide, as well as background for training employees in its handling.

CGA P-85, Guideline for Use of CGA-341 and TC-341 Cryogenic Trailers in the United States and Canada

Released: October 13, 2020 (1st Edition)

This publication contains guidelines for the use of CGA-341 and TC-341 cryogenic trailers when moved in either direction between the United States and Canada. These trailers are typically used to transport the following cryogenic liquids at pressures less than 25.3 psi (174.4 kPa) although the maximum allowable working pressures of CGA-341 and TC-341 trailers are between 25.3 psi and 150 psi (174.4 kPa and 1034.2 kPa):

  • oxygen
  • helium
  • nitrogen
  • argon

CGA P-85 also provides guidance on determining if the trailers conform to U.S. and Canadian regulatory requirements. These requirements include trailer design, year of manufacture, requalification, and maintenance.

CGA P-88, Guideline for the Maintenance of Bulk Delivery Equipment Containing Class 2 Hazardous Materials (Formerly SB-41)

Released: October 9, 2020 (1st Edition)

This publication provides guidance for the proper procedures to conduct maintenance on bulk delivery equipment containing Class 2 hazardous materials.

Bulk delivery equipment is also commonly referred to as bulk packaging. Bulk delivery equipment can include but is not limited to tube trailers (including bundles of cylinders) and cargo tankers or vessels.

CGA PS-22, CGA Position Statement on Conforming with USP/NF Monographs for Medical Gases

Released: October 21, 2020 (3rd Edition)

USP (United States Pharmacopeia) is in the process of modifying the monographs for medical gases. This position statement defines the basic industry practices that will enable a medical gas manufacturer to be in compliance with U.S. Food and Drug Administration regulations during modifications to the USP/NF monographs.

This position statement sets forth acceptable industry test practices for products manufactured at ASU (Air Separation Unit) and cylinder filling operations. It also establishes the use of industry produced reference standards that are NIST (National Institute of Standards and Technology) traceable as an acceptable practice.

CGA PS-64, CGA Position Statement on Handling Carbon Dioxide Cylinders Previously Used in Cannabis Extraction or With Food Products Containing Cannabis

Released: October 27, 2020 (1st Edition)

This publication describes CGA’s position on how the industry ensures carbon dioxide cylinders that can contain residual cannabis or hemp oils are not subsequently filled without proper processing.

CGA SA-38, Safety Alert, Potential for Hidden Cryogenic Liquid Cylinder Contamination

Released: October 21, 2020 (1st Edition)

“All cylinders have the potential for exposure to external contamination during their service life. External contamination can occur while in storage or in use in areas where contaminants are present in the form of airborne mist or particulate matter. External contamination can also occur during transportation…”
