Making Safety the Global Standard

CGA is involved in a number of international activities, including participation in the International Organization for Standardization (ISO), International Harmonization Council (IHC), and the United Nations (UN). Participation in these activities allows CGA to promote effective, consistent safety requirements in a global arena, provide industry-specific expertise to broader technical groups, develop consensus support for safety and technical requirements, extend cooperative relationships with other organizations, and proactively address regulatory concepts as they are being developed.

CGA participates in the U.S. Technical Advisory Groups (TAGs) for the International Organization for Standardization (ISO), and serves as an ANSI-accredited U.S. TAG Administrator.

U.S. positions developed by ANSI-Accredited U.S. TAGs shall be developed in accordance with applicable antitrust and competition laws, and meetings amongst competitors to develop U.S. positions are to be conducted in accordance with these laws.

U.S. TAG Membership

“Membership shall be open to all U.S. national interested parties who indicate that they are directly and materially affected by the activity of the U.S. TAG, after being informed concerning U.S. TAG working procedures and scope of activities.” U.S. TAG member responsibilities include providing comments and input to formulate a consensus U.S. position on draft standards, agenda items, and work items.

As an American National Standards Institute, ANSI-accredited U.S. TAG Administrator, CGA adheres to the following:

CGA participates as a non-governmental organization (NGO) on the UN Sub-Committee of Experts on the Transport of Dangerous Goods (SCETDG) and the UN Sub-Committee of Experts on the Globally Harmonized System of Classification and Labelling of Chemicals (SCEGHS). In this capacity, CGA represents industry positions, submits papers for consideration, makes comments regarding other submitted papers, and acts as technical advisors to participating regulatory agencies.

The UN SCETDG and SCEGHS operate on a 2-year (biennium) cycle, and meet 4 times during the biennium. Requirements agreed to by the UN Sub-Committees may be adopted into modal and domestic regulations such as the IMDG Code, ICAO Technical Instructions, U.S. Code of Federal Regulations, Canadian TDG Regulations, and other occupational safety and health regulations.

The International Harmonization Council (IHC) was established to develop international standards for industrial and medical gases. The actions of the IHC are endorsed by leading industrial gas companies and the International Oxygen Manufacturers Association (IOMA).

The IHC’s work to develop globally harmonized standards is supported by four regional Associations:

  • Asia Industrial Gases Association (AIGA);
  • Compressed Gas Association (CGA);
  • European Industrial Gases Association (EIGA); and
  • Japan Industrial and Medical Gases Association (JIMGA).

The IHC associations work cooperatively to manage joint working groups populated by industry experts from member companies. CGA provides technical, editorial, and administrative support for the joint working groups working to create and revise harmonized publications.
