Safety analysis and review

To ensure a high degree of safety, the operating organization should establish a safety review process that could be implemented by a safety review group or independent reviewers and which provides an independent evaluation of the operational activities of the plant. Safety reviews should be considered for activities such as  

Safety reviews should be conducted in sufficient depth to ensure that all issues and questions raised by the review can be satisfactorily resolved. Safety review activities should be performed by personnel who have sufficient education, nuclear experience, expertise and training to allow a thorough understanding and evaluation of the items reviewed. 

In addition, periodic safety reviews should be performed to substantiate continued safe and reliable plant operation. The results of periodic safety reviews should be used, for example

DOE Order 5480.23 specifies that hazard and accident analyses be included in safety analyses for nuclear facilities. Likewise, DOE Order 5481.IB, "Safety Analysis and Review System," requires hazard and accident analyses be included for non-nuclear facilities. Two nuclear SAR topics overlap with the PrHA.

Safety auditors should collect the following safety facilities and non-fmancial information related to the project (1) the written request for the project construction units (2) safety preassessment report (3) safety specific report and relevant documentation about project preliminary design (4) written approval of preliminary design safety fadhties of construction projects (5) the project completion report and related construction drawings (6) the safety assessment report (7) safety faciUties construction project completion and acceptance approval letter (8) technicd indicator information apphes to the audited entity s safety faciUties three simultaneous . Safety facilities "three simultaneous" can be audited by audit, supervision, observation, inquiry, confirmation, calculation, analysis and review and other conventional methods of audit. Due to the comprehensive and technology of safety audit project, safety auditors should also use cost-benefit analysis and economic evaluation of safety and other methods. 

Over the past few years, the relative emphasis of pharmacovigilance activities has shifted (Figure 6.1). In the past, most pharmacovigilance departments at biopharmaceutical companies focused on the handling of individual adverse event reports (called individual case safety reports [ICSRs]) with less attention paid to systematic analysis and review of aggregate adverse... 

Procedures should be comprehensive, validated, formally approved and subject to rigorous change control. In addition, they should be unambiguous and relevant to the actual plant (with modifications taken into account), and should reflect current practice and due consideration of human factor aspects (for example, it should be considered whether the procedures are user friendly). The review should focus on those procedures that are of high safety significance it should not entail a technical review of all procedures. (The safety significance can be determined from a deterministic safety analysis and a PSA.) The system for the development and control of procedures should be reviewed. (As far as possible, staff should participate in the development of the procedures that they use.) The review of this safety factor should include ... 

The verification of the safety assessment should be carried out by experts who are familiar with current developments in reactor technology and safety analysis. The reviewers should be independent of the designers of the plant.

A-10. For safety systems, the PSW shall be subjected to the same assessment (analysis and review) of the final product (not of the production process) as new software developed for the application. If necessary, reverse engineering shall be performed to enable the full specification of the PSW to be evaluated. 

A difficulty here can be the conflation of two issues fitness for purpose and risk-based safety justification. Sometimes (though not necessarily in these examples) it can appear to senior management that a particular safety concern has been derived solely from risk-based safety analysis, and not from a review of fitness for purpose. Senior management may think the concern is about a hypothetical fault sequence expressed in terms of probability or fault frequency, unless it is made very clear where the engineering issues lie. 

Such a result can be used to help port safety analysts to carry out formal safety assessment of a port, and to initiate safety audit and review of key performance indicators of various port departments for enhanced operation. The result of the analysis could also help analysts to propose various...

This Part reviews different risk-analysis methods. Risk analysis is a planned activity involving an identification and evaluation of accident risks in the workplace. We will start in Chapter 21 by establishing some common principles of the different risk-analysis methods. We will then in Chapters 22 to 25 go through four different methods that primarily are used in the analysis of the risk of occupational accidents energy analysis, job-safety analysis and comparison analysis. One chapter is dedicated to the risk assessment of machinery. Finally, we will in Chapter 26 review the CRIOP method, where the interaction between the operators and the technical system are analysed when the system is in a disturbed state. The aim is here to prevent major accidents. 

Chapter 3 presents introductory aspects of reliability and safety. Chapter 4 presents a number of methods considered useful to perform transportation systems reliability and safety analysis. These methods are failure modes and effect analysis, fault-tree analysis, the Markov method, hazard and operability analysis, interface safety analysis, preliminary hazard analysis, job safety analysis, and technique of operations review. 

The maintenance programme should ensure that the levels of reliability and effectiveness of all plant structures, systems and components important to safety remain in accordance with the current plant safety analysis and that the safety stams of the plant is not adversely affected after the commencement of operation. Additionally, the results of periodic reviews should be incorporated into the maintenance programme. 

Methods for performing hazard analysis and risk assessment include safety review, checkhsts, Dow Fire and Explosion Index, what-if analysis, hazard and operabihty analysis (HAZOP), failure modes and effects analysis (FMEA), fault tree analysis, and event tree analysis. Other methods are also available, but those given are used most often. 

Process Safety Analysis This part treats the analysis of a process or project from the standpoint of hazards, risks, procedures for making potential damage estimates, and project reviews and audits. It can be helpful to management in assessing risks in a project. It consists of the following ...
