> One of the points they mentioned a bit casually is that plastic tubing has no fire resistance and little mechanical strength.
Another point that I thought was understated as part of the incident report was the problem presented by storage of chemicals (gas cylinders in this case) not involved in the process within the fume hood. While fume hoods are designed to serve many different uses, they aren't designed to host more than 1 at a time. Storing gas cylinders in a fume hood is not a good use of valuable hood space. I've observed that it's a common practice that I don't quite understand. The colliery fume hood lesson learned in this story is that fume hoods aren't designed to provide any protection from fire other than segregation of the process from other chemicals.
I really appreciate the effort that went into making this video and sharing it with the community. I'm always fascinated by how many different kinds of lessons learned can be developed from the same incident, depending on the level of detail and transferability of the Lesson desired.
