International | Safety first: three new video clips from Messer inform viewers how to deal with gas cylinders safely. They describe the labeling of the cylinder contents and demonstrate the most important rules for transport and handling. The clips are a supplement to the pocket guides, which are available to download as PDFs at messergroup.com. They cover these topics comprehensively. The preparation of further video clips – on the handling of dry ice as well as how to connect up gas cylinder valves – is in progress.
