A superb video. One of the points they mentioned a bit casually is that plastic tubing has no fire resistance and little mechanical strength. Hence it is both easier to fail in an accident and more prone to failure. Many CPI research organizations have fairly restrictive rules about where it can be used (very low pressure, very low flows) and usually restrict it to a short connection if needed for flexibility.

Subject: [DCHAS-L] PNNL Hydrogen Fire Event Video

 

My colleague at the Princeton University Plasma Physics Lab (a DOE facility) sent me this video from the Safe Conduct of Research (SCoR) at the Pacific Northwest National Lab (PNNL).  There was a hydrogen fire and explosion in one of their fuel cell research labs in September 2018. This video highlights their incident investigation and lessons learned, and provides a good example of why it is necessary to continue to question and improve safety even for operations that have remained unchanged for many years with no serious incidents. This video is very well done and very much appreciated.
