Through design safety analysis

Safety professionals should be aware that more recently issued safety standards and guidelines require hazard analysis and risk assessment. Adoption of safety through design concepts is slow-moving, but certain. In time, many more safety professionals will need to become skilled in making hazards analyses and risk assessments. That spells career opportunity. 

But, because of the emergence of what has been called the safety through design movement and the recent publication of safety guidelines and standards that propose or require hazard analysis and risk assessment, special courses need to be crafted to address these additional knowledge need. 

The FTA is a diagrammatic analytical technique that is used for ReUabiUty, Maintainability and Safety Analysis. It is a top-down (deductive) analysis, proceeding through successively more detailed (i.e. lower) levels of the design until the probability of occurrence of the top event (the feared event) can be predicted in the context of its enviromnent and operation. 

Accurate and Consistent Results of a combination of analysis techniques and reviews/inspections, including safety analysis, S/W safety analysis, modelling and simulation, formal method proofs that show internal consistency and completeness, structured design waUc-throughs and inspections. 

The objective of a safety analysis is to help define and to confirm, through adequate analysis tools, the safety basis for the parts of the plant which are important for safety and to ensure that the general design of the plant is capable of complying with the dose limits in force and with the radioactive releases specified for any plant conditions. ... 

The designer, who uses the safety analysis as an important and integral part of the design process. This is continued through the manufacture and construction of the plant. 

Now, so many accidents no longer affect only one country or community, but many. To be sure that our systems are designing safety into the process, the application of risk assessments becomes paramount. And the risk assessment process is a very good structure in which to put the safety analysis tools discussed in Chapters 5 through 9. To complete the process, the safety analysis results need to be put into a context that engineers can use to make good design and operations decisions. 

The JHA is a core process element of the safety management system and offers benefits in multiple areas. As mentioned above, if you have a JHA process, it becomes part of the network of communications that spreads job information and influences safe behaviors through the organization. It covers both the job design for potential latent, built-in errors that are hidden and for potential active errors by the employee (Job Safety Analysis A Fundamental Tool for Safety, n.d. Volume 1 Concepts and principles, human performance, improvement Handbook, 2009). 

The analysis points out the increasing importance of BIM to achieve safety in construction through design and the need to integrate relevant safety information in the models.
