Accident Risk Assessment

In short, the Accident Risk Assessment provides a comprehensive, detailed evaluation of the overall accident risk associated with the operation and maintenance of a specific facility, its systems, equipment, and hardware. It incorporates the results of integrated hazard analyses, recommended design changes, hazard reports, and procedural or administrative tools which will eliminate or reduce the risk of these hazards, operational flow charts, safety-critical procedure lists, and other such information pertinent to the overall assessment of accident risk. 

The necessity to report mishaps, accidents, and/or incidents to the contracting agency should, at face value, be obvious. In fact, the occurrence of such unfortunate activities

Determining the potential for hazards to result in an accident (risk assessment) is frequently part of the identification step (see chapter 11). This list of potential hazards and their risk is used during the evaluation and control phase of the project. Resources for evaluating the hazards and developing control methods are allocated on a priority basis, giving the appropriate time and attention to the most significant hazards.

The genetic effects that could be caused by radiation are too numerous to be considered individually. For nuclear accident risk assessment, genetic disorders have been grouped as (1) dominant and X-linked single-gene disorders, (2) chromosome disorders, and (3) multifactorial disorders.

The discussion in this chapter is based on information the committee was able to gather on available test results or operational plans for use of the tools as presented by the Army. However, equipment does not always function as designed, and unexpected events—even catastrophic failures—may occur. The Army has conducted preliminary accident risk assessments of treatment systems (see, for example, U.S. Army, 2001a, Appendix D, Summary of Accident Risk Assessment ) but does not appear to have conducted an integrated site-specific risk assessment of its systems, including the risks of catastrophic failures. 

In addition to the hazardous conditions that develop during daily operations and are incorporated in the closed-loop hazard tracking system, the customer may require the contractor to perform a formal periodic risk assessment (usually annually, but it can be more frequent if the customer so desires or if operational activities dictate) of all facilities in which operations will occur. The risk assessment will also take into consideration the hazards associated with the permanent equipment and hardware assigned for use in the facility. The accident risk assessment then becomes a detailed safety analysis of a facility, including its systems and functions. 

With this, the validation of a simulation based accident risk assessment has largely become a bias and uncertainty assessment process. Within TOPAZ, a bias and uncertainty assessment method has been developed which consists of the following steps ...

Dutyholders should ensure that they have implemented a competence management system, linked to major accident risk assessment, to ensure that anyone whose work impacts on the control of major accident hazards is competent to do so. 

Specific databases are available for a wide range of uses including the recording and analysis of data on accidents, risk assessments and various test results such as audiometry and LEV tests. Several different versions of each database type, which differ in function, flexibility and price, are available on the market.
