Train derailment in NY
Here is the article:
I am always leery of statements such as “sources close to the investigation.” At any rate, fatigue is something you would want to investigate in such a case, so I’m glad they are on it.
The article also contains interesting information about some safeguards (barriers that protect targets from hazards) that were implemented previously. In trying to understand why this accident occurred, you would want to review the safeguards to see if they worked as intended. In the corrective action phase of the investigation, you would look to see if additional safeguards could be implemented or existing ones strengthened.
Would you like to learn more about investigating human performance problems (including fatigue?) and safeguards analysis? Of course you would! Plan on attending a TapRooT® course in 2009 – here is the schedule: http://www.taproot.com/courses.php
