Many safety and process safety professional think incidents like this are “rare”. They would be wrong, unless of course their definition of “rare” is a bit looser than mine! I do not have official numbers of the frequency of this type of incident but I am trying to obtain them and will certainly pass them along when, and if, I ever get them. But using my Incident Alerts from the past 14 years I have counted 78 such incidents that resulted in consequences that it made the news or triggered an agency inspection/investigation. Who knows how many occur with consequences so insignificant that they never make the news or any official reporting mechanism. But this 2012 incident is a PERFECT example of how these incidents occur and how their consequences can be lethal (however this incident only required the hospitalization of the drive for several days)…
