With some success, I have been teaching Charles Perrow’s “Normal Accident” concept with “Engineering Disasters.” It is a show on the History Channel, which is itself an offshoot of Modern Marvels). Each show is broken-down into usually four or five vignettes that are essentially “case studies” in engineering accidents and disasters.
These shows can easily be harnessed to walk students through the normal accident concept by analyzing each of the case studies using a worksheet (I could share this with anyone that wants it njr12 at psu.edu) that distills normal accidents into a few component parts. See below. I use Modern Marvels Engineering Disasters 7 in my course and in the image you see the final two cases — Northridge Earthquakes in CA and the Underground Mine Fires in Centralia, PA — and they are cross-referenced with the three criteria that I use from normal accidents, namely,
- That there is a techno-human-nature interaction that is detectable;
- That the relational interaction is sufficiently complex (and/or tightly-coupled);
- That, with regard to the resulting engineering accident or disaster, it is not reasonable to expect the designing engineers to have anticipated (i.e., predicted) the issues that lead to the engineering accident or disaster in advance.
The students, from what I can gather, enjoy doing this sort of detective work. After four or five case studies, the students typically know how to apply the criteria and, thus, the concept of normal disasters.
