The safe handling, use, storage and actual packaging of chlorine in either cylinders or ton containers has always been an important part of the Chlorine Institute's safety mission. CI’s 200 member companies represent the complete value chain—from chlorine producers to packagers, distributors, users and suppliers. The Institute’s North American producer members account for a majority of the total chlorine production capacity of the U.S. and Canada. Packager members represent a significant percentage of the total U. S. market.
Resources for Packagers
The Chlorine Institute has developed a library of technical pamphlets and training resources specifically related to the safe handling and use of chlorine cylinders and ton containers, including:
- Chlorine Basics (formerlyThe Chlorine Manual)
- Packaging Plant Safety and Operational Guidelines
- Guidelines for the Safe Motor Vehicular Transportation of Chlorine Cylinders & Ton Containers
These products can be ordered on this website in the CI Bookstore.
Proper Terms to Avoid Confusion
Please note that cylinders and ton containers have many similarities in the way in which they are handled and many users of cylinders also use ton containers. Therefore, they are considered together in discussions of chlorine packaging. However, the terms “cylinder,” “ton cylinder” or “drum” should NOT be used to describe the ton container. Emergency equipment for handling ton containers is different from that used for cylinders and confusion can be avoided if proper terms are used.
Checklists for Packagers
The Chlorine Institute has prepared a letter that describes the reasons that we developed the checklists as well as why the Institute has made their use or comparable ones a condition of CI membership.
