  2. Swiss cheese model - Wikipedia

    en.wikipedia.org/wiki/Swiss_cheese_model

    The Swiss cheese model of accident causation is a model used in risk analysis and risk management. It likens human systems to multiple slices of Swiss cheese , which has randomly placed and sized holes in each slice, stacked side by side, in which the risk of a threat becoming a reality is mitigated by the differing layers and types of defenses ...

  3. Tripod Beta - Wikipedia

    en.wikipedia.org/wiki/Tripod_Beta

    The methodology combines a number of theories of accident causation into generating a single model (a 'Tripod tree') of an accident or incident, most notably the Swiss cheese model (barrier-based risk management) and human factors-oriented theories such as GEMS (Generic Error-modelling system).

  4. Accident triangle - Wikipedia

    en.wikipedia.org/wiki/Accident_triangle

    The theory was developed further by Frank E Bird in 1966 based on the analysis of 1.7 million accident reports from almost 300 companies. He produced an amended triangle that showed a relationship of one serious injury accident to 10 minor injury (first aid only) accidents, to 30 damage causing accidents, to 600 near misses.

  5. James Reason - Wikipedia

    en.wikipedia.org/wiki/James_Reason

    Among his many contributions is the introduction of the Swiss cheese model, a conceptual framework for the description of accidents based on the notion that accidents will happen only if multiple barriers fail, thus creating a path from an initiating cause all the way to the ultimate, unwanted consequences, such as harm to people, assets, the ...

    The Human Factors Analysis and Classification System (HFACS) identifies the human causes of an accident and offers tools for analysis as a way to plan preventive training. [1]

  7. Accident analysis - Wikipedia

    en.wikipedia.org/wiki/Accident_Analysis

    In accident analysis it could be used to determine leading factors, post-incident. This model works like a flow chart to help show all processes and systems that may have effected the outcome of the incident. Failure Mode and Effect Analysis: This model uses a quantitative value to represent qualitative metrics like probability and severity ...

    Heinrich's classic work was refuted by a 1980 book Industrial Accident Prevention, by Nestor Roos, H Heinrich, Julienne Brown and Dan Petersen. [6]Heinrich Revisited: Truisms or Myths by Fred A. Manuele, CSP, PE [2002, ISBN 0-87912-245-5 published by National Safety Council offers the following in the last chapter.

  9. AcciMap approach - Wikipedia

    en.wikipedia.org/wiki/AcciMap_Approach

    The AcciMap approach is a systems-based technique for accident analysis, specifically for analysing the causes of accidents and incidents that occur in complex sociotechnical systems. The approach was originally developed by Jens Rasmussen [ 1 ] as part of a proactive risk management strategy, but its primary application has been as an accident ...
