My Unpublished Works


    Examples of Unpublished Works

A. This section contain a list of works in process that I am developing for potential future publication. These works might be of interest for their potential contributions or use by others. Comments are invited.

  1. Sugegested editorial for a safety research journal (draft)

    The objective of this paper is to altert safety researchers to the variations in reported safety/accident investigation data due to at least 28 different investigation methodologies/methods used to conduct them, with suggestions for reserchers to minimize their effects on the researcher's work products. View document. Expands on variations mentioned in on-line paper What do STAMP-based Analysts Expect from Safety Investigations?

  2. Bifurcation of Accident Investigation Functions

    This research describes problems due to conflation of functions found in today's accident investigation processes, the need for change, and how mishap investigations could be conducted, reported and used to overcome those problems.

B. This section contains unpublished surveys, tables and charts I have created.

  1. Student survey. Results of survey responses of students attendaing a 1982 USC Accident Investigation course. Most all students had some investigation and a few had safety position experiences.The survey solicited their definitions of CAUSE and FACTORS they would use in accident investigqtions. View the results here.

C. This section contain a list of unpublished works I initiated and sometimes developed with coauthors or in collaboration with others. These works might be of interest for their potential exploitation by others. Comments are invited.

  1. Historical Risk Analysis Document:

    I have posted an early internal staff working draft of a technical document I prepared at the NTSB in 1971-1972 at the request of and in consultation with the Bureau Director, Henry Wakeland. It contains the risk oriented basis for focusing the Board's HazMat safety efforts on emergency responder safety and tank car head shield retrofits. It also generated , the insights for GEBMO, DECIDE, TRACEM and other models that were developed for Frank Brannigan's Fire Science curriculum at Montgomery College in subsequent years. The study was overtaken by external events before it was completed, and was not further developed for consideration by the Safety Board.

  2. Draft Aircraft Fire research report

    This project was undertaken to determine if aircraft fire losses might be addressed using an analysis method I developed to assess the effectiveness of emergency responses to hazmat accidents. The method is called Time/Loss Analysis. (T/LA) It uses best estimates of the loss accumulation over time as the emergency progresses to its conclusion. T/LA was used as a tool in the MORT program shortly after it was developed and publicly shared as MES Guide 7, first published in 1979. I used it experimentally at the NTSB to try to isolate response problems. This was the first attempt to apply it to aviation fire responses.To view a 2003 draft, see LOSS HISTORIES: A UNDERUSED SAFETY RESOURCE

    My special thanks to Mike Murphy for his many many contributions.

D. Examples of unpublished works prepared for private use

  1. Benner, L., REFLECTIONS ON SCIENTIFIC METHOD, course handout, USC Accident Investigation Course, ISSM 514, 1978.

  2. Internal document for NTSB: Background Paper: Hazardous Materials Emergency Response Network, TE40 (L Benner) Hazmat Div to provide talking points in support of an NTSB recommendation.

  3. L Benner, 3 DAY ADVANCED ACCIDENT INVESTIGATION COURSE, example of 1980s investigation courses, based on the then current state of the art. 18 blocks plus handouts, for USC ISSM for a railroad company.

  4. Numerous other accident investigation courses presented to various corporate, union and government audiences are not reproduced here.

  5. These sections will be supplemented as time permits.
