The Compressed Gas Association (CGA) publishes a growing library of resources for users at all experience levels with our industry’s products, as a means of communicating safety information on a wide variety of important topics.


CGA maintains a library of over 400 publications, safety alerts, safety bulletins, technical bulletins, technical reports, training materials, and our Handbook of Compressed Gases.

Safety Posters

Free downloadable safety posters. Take advantage of and share these free resources to help ensure that all those who come in contact with our industry’s products, may do so safely.

Safety Information

For many of our most popular and searched compressed gases, we publish a “Safety Resource Center”, which provides safety information, related free poster downloads, and other resources in one place.

E-Learning Modules

Our growing library of eLearning modules present core concepts from our standards library in a format that is accessible and engaging for employees who are new to the industry.


We publish a steady stream of news articles to this section of our website to help keep all those in the compressed gas industry – both CGA members and non-members – fully informed.

Hydrogen Safety

Hydrogen has been growing in popularity as a viable renewable energy source. CGA has standards, guides, infographics, videos, and more to help learn about hydrogen safety.

Featured Resource

CGA is modernizing the CGA Handbook of Compressed Gases by making it a virtual tool, and we are pleased to announce that the gas monographs are now available in electronic format and can be accessed by going to the Handbook publication detail page and then clicking on the “Handbook Online” button.

The gas monographs provide information on the properties, uses, emergency response, safety, and special handling information for fifty-eight (58) of the most common compressed gases. Each gas monograph opens with basic identifying information: chemical name of the gas, its chemical symbol, synonyms, CAS registry number, DOT and TC proper shipping name, classification, labels, assigned UN number, and GHS classification.
