September 15, 2019

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

CGA C-6 – Standard for Visual Inspection of Steel Compressed Gas Cylinders

Released: August 19, 2019 (12th Edition)

Special Attribute:

  • Referenced by National Fire Protection Association (NFPA)

Provides cylinder users (requalifiers, owners, fillers, operators, etc.) with criteria to accept, reject, and condemn steel compressed gas cylinders. This standard does not cover all circumstances for each individual cylinder type and condition of lading.

Inspection procedures include preparation of cylinders for inspection, exterior inspection, interior inspection (if required), nature and extent of damage to be looked for, and some tests that indicate the conditions of the cylinder, etc.

Previous editions of this publication have been cited in Title 29 (Labor) and Title 49 (Transportation) of the U.S. Code of Federal Regulations (CFR), commonly referred to as “29 CFR” and “49 CFR.”

CGA C-6.1 – Standard for Visual Inspection of High Pressure Aluminum Alloy Compressed Gas Cylinders

Released: August 19, 2019 (7th Edition)

This standard has been prepared for the visual inspection of aluminum alloy compressed gas cylinders with service pressures of 1800 psi (12 410 kPa) or greater. This standard does not address all cylinder manufacture defects.

Cylinders authorized by regulation may require testing by ultrasonic examination (UE) or pressure testing. This standard does not include testing that may be required by regulation.

A previous edition of this publication has been cited in Title 49 (Transportation) of the U.S. Code of Federal Regulations (CFR), commonly referred to as “49 CFR.”

CGA P-5 – Care of High Pressure Cylinders for Underwater Breathing

Released: August 19, 2019 (7th Edition)

Steel and aluminum alloy compressed gas cylinders used for underwater diving service in self-contained underwater breathing apparatus (SCUBA) are exposed to extremely harsh conditions. Corrosion caused by seawater can weaken cylinders. Residue from corrosion can clog valves and regulators, resulting in reduced or blocked airflow.

For cylinders used in underwater diving, proper maintenance ensures a long life, satisfactory service, safety, and reliability.

This publication provides recommendations for the care of high pressure cylinders used for underwater breathing, recognizing the extreme conditions to which these compressed gas cylinders are exposed.

CGA P-83 – Guidelines for Cleaning Externally Contaminated Medical Gas Containers

Released: August 18, 2019 (1st Edition)

Special Attribute: Harmonized

Medical gas containers can become externally contaminated due to their use in healthcare facilities and home care settings. They can also become contaminated as a result of natural disasters such as floods, hurricanes, fires, or earthquakes.

This guideline addresses the handling and external condition of medical gas containers and the removal of contaminants from these containers.

This publication does not address the internal condition or product quality of the container.

CGA C-8F – Norme Sur la Requalification des Bouteilles en Acier Sans Soudure DOT-3HT, CTC-3HT et TC-3HTM

Released: August 20, 2019

French translation of CGA C-8Standard for Requalification of DOT-3HT, CTC-3HT, and TC-3HTM Seamless Steel Cylinders (2017 – 8th Edition).
