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

CGA AV-30 and AV-31, Technical Presentations: Part 1 & 2 – Hydrogen Supply Systems

Released: February 5, 2020

Part 1 of this series covers the following topics:

  • Typical industrial gas supply system standards;
  • Material properties;
  • Pipe materials;
  • Regulators and other components;
  • Weather protection; and
  • Setback distances to exposures

Part 2 covers the following topics:

  • Cryogenic tank components;
  • Vaporizers;
  • Venting from valves and PRDs (pressure relief devices);
  • Equipment grounding;
  • Electrical classified areas; and
  • OSHA Process Safety Management (PSM) and EPA Risk Management Program (RMP)

CGA H-15, Safe Catalyst Handling in HYCO Plants

Released: February 18, 2020 (1st Edition)
Special Attribute: Harmonized publication

This publication applies to HYCO plants that produce hydrogen, carbon monoxide, or mixtures thereof, with a nominal production capacity greater than 9 MMSCFD hydrogen or carbon monoxide/syngas (approximately 10 000 Nm3/hr). Many of the concepts and issues discussed may also apply to smaller HYCO plants depending on the technology used.

This publication covers the safety aspects of all catalysts and chemisorbents such as zinc oxide used in HYCO facilities. Non-catalytic material such as physical adsorbents, for example, those used for pressure swing adsorbers; activated carbon, ion exchange resins, and inert solids (e.g., sand) are excluded from the publication. The publication scope is limited to catalyst and chemisorbent handling, loading, preparation for operation, unloading, and disposal. The publication scope excludes periods when the reactor is in operation (including startup and shutdown). Catalyst-specific instructions related to startup with new catalyst and shutdown prior to catalyst removal are included in the catalyst manufacturer’s documentation, which should be consulted. This publication is not intended to replace catalyst manufacturers’ operating manuals, handling manuals, or safety data sheets (SDS).

CGA P-87, Guideline for Avoiding Container Product Migration and Contamination During Use (Formerly SB-36)

Released: February 18, 2020 (1st Edition)

While compressed gas containers have been filled and used safely for decades, wherever more than one container or process stream is connected to a system, there is potential for product migration or back contamination.

This publication is intended for users, fillers, and designers of gas delivery systems. It provides steps that can be taken to minimize, if not eliminate, the risk of product migration or back contamination.

CGA PS-58, CGA Position Statement on Acetylene Plant Safe Operating Pressures and Temperatures

Released: February 11, 2020 (1st Edition)
Special Attribute: Harmonized publication

This publication provides CGA’s position on operating pressure and temperature limits for acetylene production plants.

CGA SA-34, Safety Alert, Blended Breathing Air Fatalities

Released: February 20, 2020 (1st Edition)

This alert provides a list of publications with recommendations in the interest of worker safety, in regards to supplied breathing air cylinders and level of oxygen contained in them.

CGA SA-35, Safety Alert, Cleaning of Cylinders Returned from Health Care Facilities During a Pandemic

Released: March 27, 2020 (1st Edition)

As health care providers around the world work to assist patients affected by the respiratory illness Coronavirus Disease 2019 (COVID-19), medical gas containers might become externally contaminated due to their use in health care facilities. It is important that these containers are cleaned in a manner that removes contaminants, does not cause damage to the container, valve, or gas product, and does not lead to a hazardous situation during the refilling and use of the container’s contents.
