NOTES

RESEARH UODATES: This page will be updated as relevant projects are brought to my attention. Any references to INVESTIGATION PROCESS RESEARCH projects are welcomed. References or research with the objective of assessing quality of investigation work products also would be helpful. Send a message to me at this iprr.org site with sufficient information to permit me to establish contact with the Project Director or report author, such as name and e-mail address (preferred), URL, telephone number, fax number, or snail mail address


HISTORICAL PERSPECTIVE: View two documents describing then current thinking about aircraft accidents in 1927 and 1928, if you are interested in tracking sources of the conventional wisdom about investigations. Also I found an in house draft 1972 study with a method for hazmat rail transportation risk analysis that might be of historical interest. (See also the on-line experimental research project )


HAZMAT RESERCH: While the Site Administrator was the NTSB's principal hazardous materials specialist at the NTSB, significant hazmat investigation research and safety progress occurred. Click here to view a discussion of that INVESTIGATION/RESEARCH relationship.

The aim of this research is to try and improve the way that information about accidents is communicated. They are not trying to criticize the way in which accident reports are created or written but we are trying to look at the problems that the reader has in understanding those reports. This information can then be fed back into the writing process or be used to look at alternative forms of visualizing and structuring the information from accidents, Again, thanks for sharing your work product with me..
