Systemic causation model

A SYSTEMIC CAUSATION MODEL FOR HAZARDS-RELATED INCIDENTS... 

It is a necessity that the advice given by safety professionals be based on an understanding of the reality of causal factors and actually serves to attain a state for which the risks are judged to be acceptable. I will develop a systemic causation model for hazards-related occupational incidents that represents the thoughts set forth in this chapter. 

To promote an understanding of this systemic, causation model, meanings are given here of the terms incidents, hazards, HAZRINS, model, causation, causal, factors, and causal factors. 

I conducted workshops on selected incident reports they had sent me. To help the attendees explore the reality of accident causation, they were given copies of the exhibit A Systemic Causation Model for Hazards-Related Incidents shown in Chapter 10. It works as a reference base. The point to be made was this The employees in that entity could do a good job of investigation if management so required. 

Chapter 10, A Systemic Causation Model for Hazards-Related Incidents ... 

In recognition of the need to further our knowledge of hazards-related incident causation, a chapter offers A Systemic Causation Model for Hazards Related Occupational Incidents. ... 

In Chapter 3, Serious Injury Prevention, an outline for such a study was presented under the heading Proposing a Study of Serious Injuries. Such a study will not be time-consuming since the data to be collected and analyzed should already exist or can be obtained easily. To assist in such a study, two addenda are provided at the conclusion of this chapter. Both are reprinted Ifom the third edition of On The Practice Of Safety Addendum A, A Systemic Causation Model for Hazards-Related Incidents, and Addendum B, Reference for Causal Factors and Corrective Actions. Another good reference when completing this evaluation, in terms of its comments on human errors that may be made above the worker level, is Chapter 4 here. 

In Chapter 8, Improving Serious Injury and Fatality Prevention, this author wrote that risk assessments should be established as the core of an occupational risk management system. So, also, should risk assessment be a major element in a systemic causation model. 

Thus, the case can be soundly made that risk assessment should be the core of an Occupational Risk Management System—and a significant element in a systemic causation model because less than adequate avoidance decisions or control methods may result from poorly done or totally absent risk assessments. An outcome of the risk assessment process is to prioritize risks for orderly consideration. 

Since it is well established that the most effective and economic method of achieving and maintaining acceptable risk levels it to address hazards and risks in the design and redesign processes, prevention through design must be given prominence in a systemic causation model.
